Rf Mvs's questions

I am putting 3 Fragments with their 3 corresponding xml with a background that is an image but they are not very big only 3 MB, but they have a resolution of approximately 4K and it gives me the following error

2019-07-29 22:36:11.418 21832-21832/com.example.images E/AndroidRuntime: FATAL EXCEPTION: main Process: com.example.images, PID: 21832 java.lang.RuntimeException: Unable to start activity ComponentInfo{ com.example.images/com.example.images.MainActivity}: android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class android.widget.RelativeLayout at android.app.ActivityThread. performLaunchActivity(ActivityThread.java:2665) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2726) at android.app.ActivityThread.-wrap12(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread. java:1477) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6119) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java: 886) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:776) Caused by: android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class android.widget .RelativeLayout Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class android.widget.RelativeLayout Caused by: java.lang.reflect.InvocationTargetException at java.lang.reflect.Constructor.newInstance0(Native Method) at java.lang.reflect.Constructor.newInstance(Constructor.java:430) at android.view.LayoutInflater.createView(LayoutInflater.java:645) at com.android.internal.policy.PhoneLayoutInflater.onCreateView(PhoneLayoutInflater.java:58) at android.view.LayoutInflater.onCreateView(LayoutInflater.java:717) at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java :785) at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:727) at android.view.LayoutInflater.inflate(LayoutInflater.java:495) at android.view.LayoutInflater.inflate(LayoutInflater.java:426) at android .view.LayoutInflater.inflate(LayoutInflater.java:377) at android.support.v7.app.AppCompatDelegateImplV9.setContentView(AppCompatDelegateImplV9.java:287) at android.support.v7.app.AppCompatActivity.setContentView(AppCompatActivity.java:139 ) at com.example.images.MainActivity.onCreate(MainActivity.java:35) at android.app.Activity.performCreate(Activity.java:6679) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1118) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2618) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2726) at android.app.ActivityThread.-wrap12(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1477) at android.os.

Do I have to use Glide?

Glide.with(getApplicationContext()).load(mBundle.getInt("Image")).into(mPlace);

How would I use it in a Fragment?

Here is my Fragment (the other 2 are the same):

public class PageFragment1 extends Fragment {

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {


    ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.page_1, container,false);
    return rootView;


}
}

and my activity page_1.xml

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@drawable/portada">

<TextView
    android:id="@+id/file_type_logo_1"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:fontFamily="@font/simonetta_black_italic"
    android:text="Divertido"
    android:textColor="#FFFFFF"
    android:textSize="50sp" />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:layout_alignParentBottom="true">
    <ImageView
        android:id="@+id/file_type_logo_2"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:background="@drawable/downarrow" />

</RelativeLayout>

cover is the 4K image or I don't know why the app crashes when I launch it...

EDIT

MainActivity.java :

public class MainActivity extends AppCompatActivity {

private VerticalViewPager viewPager;
private PagerAdapter pagerAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.page_1);

    List<Fragment> list = new ArrayList<>();
    list.add(new PageFragment1());
    list.add(new PageFragment2());
    list.add(new PageFragment3());

    viewPager = findViewById(R.id.pager);
    pagerAdapter = new VPagerAdapter(getSupportFragmentManager(),list);
    viewPager.setAdapter(pagerAdapter);



}



}

EDIT2:

Now it won't let me start the App, the error I have is the following and I don't know why:

Out of memory, I have tried to put a thousand solutions as in Manifestthe android:largeHeap="true"typical one and another that is usually commented on but nothing, if I put icons instead of large images, it works, because of the size, how can I incorporate images of 10 MB or more in my App or does it have a limit and I have to download them to 5MB or how much?

Landscape.java:

I am following this tutorial: https://www.youtube.com/watch?v=VQwZQz9qsDA but when I have to do the activity_main I do it as is:

<vpv.iso.com.viewpagervertical.VerticalViewPager
    android:id="@id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

but it gives me the following error

Caused by that, I don't know how to make the vertical slider work anymore, it just fails me there. I think it also has to do with the fact that at the start of the video he has 2 folders created with that name and I don't, and that I have created an xml called pager.xml that only has the following:

<resources>
<item
    type="id"
    name="pager" />
</resources>

I am trying to make an app and I want to add a splash screen to it. Tired of having static splash screen I'm thinking of making one that I've seen in the root app "KingRoot" but I don't know the name or where to find information about it.

It is treated as if it were the same vertical image but that it occupied 3 vertical screens, that is, you slide with your finger and you go down, the screen that is disappearing at the same time as you go down and the next screen appears, and so on with the third also. I would like to know the name to be able to look up information about it or whether it is natively in C# or Java.

EDITED:

Code to make Slide horizontally and with depth but my need is to convert it to Slide VERTICAL and remove that depth:

public class DepthPageTransformer implements ViewPager2.PageTransformer {

private static final float MIN_SCALE = 0.75f;

public void transformPage(View view, float position) {
    int pageWidth = view.getWidth();

    if (position < -1) { // [-Infinity,-1)
        // This page is way off-screen to the left.
        view.setAlpha(0f);

    } else if (position <= 0) { // [-1,0]
        // Use the default slide transition when moving to the left page
        view.setAlpha(1f);
        view.setTranslationX(0f);
        view.setScaleX(1f);
        view.setScaleY(1f);

    } else if (position <= 1) { // (0,1]
        // Fade the page out.
        view.setAlpha(1 - position);

        // Counteract the default slide transition
        view.setTranslationX(pageWidth * -position);

        // Scale the page down (between MIN_SCALE and 1)
        float scaleFactor = MIN_SCALE
                + (1 - MIN_SCALE) * (1 - Math.abs(position));
        view.setScaleX(scaleFactor);
        view.setScaleY(scaleFactor);

    } else { // (1,+Infinity]
        // This page is way off-screen to the right.
        view.setAlpha(0f);
    }
}}

Should I change the "X" to "Y"?

I have tiempo -= Time.deltaTime;and when it reaches 0 I want it to be replaced according to a variable that is being added, that is to say, i = 2when time reaches 0, what tiempo = 2, and then a tiempo = 3... because there will be a i++, but if I put it tiempo = ior tiempo = +inot it understands nothing and it doesn't take me i, why? they are floatboth.

code:

void Update(){

   float tiempo,i=2;
   tiempo -= Time.deltaTime;
   i++;

   if(tiempo == 0)
   tiempo = i;  // Esto no me coge que es i
}

I have a GameObject that works as an object generator and they are generated along the y-axis, that is, straight, according to this function:

public void Generar() {

    Instantiate (obj [Random.Range (0,obj.Length)], transform.position, Quaternion.identity);
    InvokeRepeating ("Generar", 3, 180);
}

How can I make them parallel to the x axis? I have already put in the generator the objects that have to be generated in the correct way, parallel to the x axis, but they come out as before, why? i tried to put in above function transform.position.xbut i get error.

I am making a game in Spanish but if they download it from another country they will not understand it, so I have to make it detect the language of the mobile and choose it stringdepending on the language. Is it done as in Android Studio? I haven't found any information about it...

I have a scene with 1 moving object and a canvas with a button playand when I run the scene the object moves because it has a certain Script assigned with a speed and so on... But the button playis in the center.

What I want is for everything to be still and when I hit the button, the button it will be with disappears button.setActive(false)and the object moves.

I'm trying to access them scriptsto do it but it won't let me refer to them and I don't want to start putting them staticor not staticbecause it would throw everything off, how can I do it so that once I hit the play button on the canvas, the other is executed? Within the same scene everything.

A possible solution would be to cancel 1 scriptand until you give "play" not execute that script (the movement of the object), but how do you do that?

Script to move the object:

public class MoveBall_ : MonoBehaviour {


public float velocidad = 10f;


private void Update()
{
    transform.Translate(new Vector3(1f, 0f, 0f) * velocidad * Time.deltaTime);
}
}

What I need is for that to velocidadbe 0 before clicking on the button playon the canvas, and when clicking on the playsecondary canvas that I have placed (which I think I know how to do) disappears and the ball starts to move just like that Script .

I have 2 numberPickerin one dialog. The problem is that if I select "seconds" and then "minutes" and click ok, the numbers are saved well . But if I do it the other way around, the seconds take those of the previous configuration, why?

I have put it, as there is only 1 button, which is saved in the 1st numberpicker, inuser_minutos.setText

 //PRIMER NUMBERPICKER

 NumberPicker.OnValueChangeListener myValChangedListener = new NumberPicker.OnValueChangeListener() {

        @Override
        public void onValueChange(NumberPicker picker, int oldVal, int newVal) {
            user_minutos.setText(newVal + " min "+ minutos2 +"seg");
            minutos = newVal;


        }
    };

    aNumberPicker.setOnValueChangedListener(myValChangedListener);

//SEGUNDO NUMBERPICKER

NumberPicker.OnValueChangeListener myValChangedListener2 = new NumberPicker.OnValueChangeListener() {

        @Override
        public void onValueChange(NumberPicker picker, int oldVal, int newVal2) {
            //user_minutos.setText(newVal + " seg");
            minutos2 = newVal2;

        }

    };

    aNumberPickerA.setOnValueChangedListener(myValChangedListener2);

Does anyone do this or has anyone used this type of background Theme? EclipseIt's exactly what I'm looking for, but with any color I use, it logically stays matte, it's not the result, it must be translucent.

UPDATE:

My xml code where I have a button that is the one that I have to modify so that it applies to all, since I have a list as in the example:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" 
>

 <RelativeLayout
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_alignParentLeft="true"
     android:layout_alignParentRight="true"
     android:layout_alignParentTop="true"
     android:layout_marginTop="0dp"
     android:background="@drawable/translucido" >

 </RelativeLayout>

</RelativeLayout>

I am trying to get it to accept the accent marks but no one has managed to solve this problem for me, it does not directly read the letters with accent marks, therefore the only solution that I think is simpler is that if you enter an accent mark, it will change it for the same one without an accent mark, it is say, "á" for "a", "é" for "e" ... and so on.

I'm going to help you too because I found this code that does what I'm telling you, but I don't know how to put it in my code.

Character change example:

public static String remove1(String input) {
  // Cadena de caracteres original a sustituir.
  String original = "áàäéèëíìïóòöúùuñÁÀÄÉÈËÍÌÏÓÒÖÚÙÜÑçÇ";
  // Cadena de caracteres ASCII que reemplazarán los originales.
  String ascii = "aaaeeeiiiooouuunAAAEEEIIIOOOUUUNcC";
  String output = input;
  for (int i=0; i<original.length(); i++) {
      // Reemplazamos los caracteres especiales.
      output = output.replace(original.charAt(i), ascii.charAt(i));
  }//for i
  return output;
}

That is what I have found on the Internet, one of many, but my code is this (and it does work):

public class Admin extends AppCompatActivity {
EditText titulo_in;
EditText descripcion_in;
Button btnActualizarA;


String recuperado="";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.admin);

    titulo_in = (EditText)findViewById(R.id.titulo_in);
    descripcion_in = (EditText)findViewById(R.id.descripcion_in);

   // titu = titulo_in.getText().toString();
    //desc = descripcion_in.getText().toString();



    final Bundle recupera=getIntent().getExtras();
    if(recupera!=null){
        recuperado=recupera.getString("cod");
    }

    btnActualizarA=(Button)findViewById(R.id.publicar);
    btnActualizarA.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Thread tr2=new Thread(){
                @Override
                public void run() {
                    ActualizarPost(recuperado, titulo_in.getText().toString(), descripcion_in.getText().toString());

                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            Toast.makeText(getApplicationContext(),"Se ha completado la publicación", Toast.LENGTH_SHORT).show();
                        }
                    });
                }
            };
            tr2.start();
        }
    });


}

public void ActualizarPost(String c, String tit, String des){
   // HttpURLConnection conection=null;
    try{
        String titleUtf8 = URLEncoder.encode(tit, "UTF-8").replaceAll("\\+","%20");
        String descriptionUtf8 = URLEncoder.encode(des, "UTF-8").replaceAll("\\+","%20");

        String urlParameters="cod="+c+"&tit="+titleUtf8+"&des="+descriptionUtf8;


        URL url=new URL("http://rudeboys.esy.es/ramiroconnect/publicar.php");
        HttpURLConnection conection = (HttpURLConnection) url.openConnection();
       // conection.setRequestProperty("Content-Type","UTF-8");

        //estableciendo el metodo
        conection.setRequestMethod("POST");

        //longitud de datos que se envian
        conection.setRequestProperty("Content-Length", "" + Integer.toString(urlParameters.getBytes().length));
       // conection.setRequestProperty("Content-Type", "application/json; charset=utf-8");


        //comando para la salida de datos
        conection.setDoOutput(true);

        DataOutputStream wr = new DataOutputStream(conection.getOutputStream());
        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(wr, "UTF-8"));
        writer.write(urlParameters);
        writer.close();

        InputStream is =conection.getInputStream();
    }catch (Exception ex){}
}

}

How can I change the code so that it updates the data in the DB without accents?

I just need to know if it's english go to url2 and if it's spanish url . I have some layouts with strings in Spanish and English and I know how to use them to exit depending on the user's language, but since it's a URL, I'm not able to make it go to one URL or another.

I have tried putting a string and comparing it or assigning numbers to it but nothing, I am not able. The solution would be if(es ingles) { go to url2} if not (spanish}

public class Competidores extends android.support.v4.app.Fragment {

WebView appWeb;

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.four_tab, container, false);


    String url = " https://rudeboysapp.wordpress.com/";
    String url2 = " https://rudeboysappenglish.wordpress.com/";

  if(l7 == "es") {

        appWeb = (WebView) v.findViewById(R.id.webView);
        //Habilitamos el javaScript y el zoom
        appWeb.getSettings().setJavaScriptEnabled(true);
        // appWeb.getSettings().setBuiltInZoomControls(true);
        //Cargamos el enlace definido
        appWeb.loadUrl(url);
        //Este método es para que el navegador se quede en nuestra aplicación
        appWeb.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                return false;
            }
        });

    }else {


        appWeb = (WebView) v.findViewById(R.id.webView);
        //Habilitamos el javaScript y el zoom
        appWeb.getSettings().setJavaScriptEnabled(true);
        // appWeb.getSettings().setBuiltInZoomControls(true);
        //Cargamos el enlace definido
        appWeb.loadUrl(url2);
        //Este método es para que el navegador se quede en nuestra aplicación
        appWeb.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                return false;
            }
        });

    }




    return v;
}

I have the following inside the method onCreate()and it must necessarily be there:

do {

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(R.string.contacto).setIcon(R.drawable.rudeboys_icon);
builder.setMessage("hola");
builder.show(); } while(timer_dialog<10);

Which shows a dialog with the text "hello" and my timer_dialog that will be my time of 10 seconds, but in the onCreate I don't know how to put it.

In a function I know it is something like :

timer = new CountDownTimer(tiempo_dialog * 1000, 1000) {

        @Override
        public void onTick(long millisUntilFinished) {
            crono.setText("" + String.format(FORMAT, TimeUnit.MILLISECONDS.toHours(millisUntilFinished),
                    TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millisUntilFinished)),
                    TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished))));


        }
        @Override
        public void onFinish() { //finalizar dialog } }

How can I do it ? I have put a do-while , is it the most efficient?

I have put in my application for the API de Google(to use the Maps) and the following lines of code so that in all the devices (including those superior to 6.0) they can give permissions and that it works correctly. The code works and a sign appears asking for permission, you put "OK" and it starts again letting you use the map.

The problem is that before that banner a banner appears saying that the application has stopped and I don't want that banner to appear. Missing??

Part of the code where the permissions are:

if (Build.VERSION.SDK_INT >= 23) {

        if (ContextCompat.checkSelfPermission(getActivity(), android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED){
        } else {
            ActivityCompat.requestPermissions(
                    getActivity(), new String[] { android.Manifest.permission.ACCESS_COARSE_LOCATION, android.Manifest.permission.ACCESS_FINE_LOCATION }, 1337);
        }
    }

Permissions that I have in the manifest are among others:

the of ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATIONandLOCATION_REQUEST_CODE

What I got in the log:

FATAL EXCEPTION: main Process: com.test.rudeboys.rudeboys1, PID: 6957 java.lang.SecurityException: my location requires permission ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION at maps.ad.tc(Unknown Source) at xj.onTransact(:com.google. android.gms.DynamiteModulesB:274) at android.os.Binder.transact(Binder.java:387) at com.google.android.gms.maps.internal.IGoogleMapDelegate$zza$‌​zza.setMyLocationEna‌​bled(Unknown Source ) at com.google.android.gms.maps.GoogleMap.setMyLocationEnabled(U‌​nknown Source) at –

Updated, what I have in the onCreate:

public class Map_fragment extends Fragment implements OnMapReadyCallback {

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.activity_map, container, false);

    if ( Build.VERSION.SDK_INT >= 23) {
        if (ContextCompat.checkSelfPermission(getActivity(), android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED){
        } else {
            ActivityCompat.requestPermissions(
                    getActivity(), new String[] { android.Manifest.permission.ACCESS_COARSE_LOCATION, android.Manifest.permission.ACCESS_FINE_LOCATION }, 1337);
        }
    }



    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
   // MapFragment mapFragment = (MapFragment) getActivity().getFragmentManager().findFragmentById(R.id.mapid);
   // mapFragment.getMapAsync(this);
   // USO SUPPORTMAPFRAGMENT PORQUE SOLO CON MAPFRAGMENT SE ME CRASHEABA AL VOLVER A ENTRAR AL MAPA!!
    SupportMapFragment mapFragment = (SupportMapFragment) this.getChildFragmentManager().findFragmentById(R.id.mapid);
    mapFragment.getMapAsync(this);
    return v;
}

But below ifit was this line: map.setMyLocationEnabled(true);and now it gives me an error because the if I have uploaded it above to onCreate , and this line has been left hanging because it needs the checkSelfPermission, how do I do it?

You see, I have an App with a Bottom bar with 5 buttons corresponding to 5 fragments, and when entering the application, of course, it loads the first fragment which is a database. The code of said fragment is the following:

public class First_fragment extends Fragment {

    ListView lstCursos;
    String recuperado;
    public final static String CLAVE_EXTRA_PASAR2 = "true";

    private ListView mylist;

    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        View v = inflater.inflate(R.layout.first_tab, container, false);
        //De este modo cambiamos el tema para cada uno de los layout
        getActivity().setTheme(R.style.Barra);

        getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

        Bundle recupera = getActivity().getIntent().getExtras ();
        if (recupera != null) {
            recuperado = recupera.getString ( "cod" );
        }

        Thread tr2 = new Thread () {
            @Override

}

Lo que sucede que si la uso sin Wi-Fi o sin datos, es decir, sin Internet, la App crashea al iniciarla, supongo que será porque como no hay Internet no puede accedes a la data base. Por tanto intenté poner en el **Main Activity un try-catch donde llamo al 1º fragment para que no crasheara sin éxito alguno** : 



``if (i == R.id.one) {``  // AQUI CARGO EL PRIMER FRAGMENT

                    First_fragment f1 = new First_fragment();
                    getSupportFragmentManager().beginTransaction().replace(R.id.frame, f1).commit();
                    currentFragment  = 1;
                }

                if (i == R.id.two) { // AQUI CARGO EL SEGUNDO FRAGMENT

                    //Second_fragment f2 = new Second_fragment();
                    Second_renovado_fragment f2 = new Second_renovado_fragment();
                    getSupportFragmentManager().beginTransaction().replace(R.id.frame, f2).commit();
                    currentFragment  = 2;
                }

                if (i == R.id.three) { AQUI CARGO EL TERCER FRAGMENT

                    Three_fragment f3 = new Three_fragment();
                    getSupportFragmentManager().beginTransaction().replace(R.id.frame, f3).commit();
                    currentFragment  = 3;
                }

                if (i == R.id.four) { // AQUI CARGO EL CUARTO FRAGMENT

                    Four_fragment_list f4 = new Four_fragment_list();
                    getSupportFragmentManager().beginTransaction().replace(R.id.frame, f4).commit();
                    currentFragment  = 4;
                }

                    getSupportFragmentManager().beginTransaction().replace(R.id.frame, f5).commit();
                   // startActivity(new Intent(MainActivity1.this, MapActivity.class));
                    currentFragment  = 5;
                }
            }

        });

        mBottomBar.mapColorForTab(0, "#c92029");
        mBottomBar.mapColorForTab(1, "#c92029");
        mBottomBar.mapColorForTab(2, "#c92029");
        mBottomBar.mapColorForTab(3, "#c92029");
        mBottomBar.mapColorForTab(4, "#c92029");

        // seems this is  working to highlist tab
        mBottomBar.selectTabAtPosition(0, true);



        try {  ////////ESTE ES EL TRY-CATCH DEL QUE HABLO//////////

            // Loading first Fragment to FrameLayout manually
            First_fragment f1 = new First_fragment();
            getSupportFragmentManager().beginTransaction().replace(R.id.frame, f1).commit();
        }catch (Exception e){}

What I can do ?

What appears in the log:

I have commented lines 55 and 101 that give errors in the log in the above code to easily locate them

I have in an Fragmentimplemented Google APIand WORKS . But it works on my 3 phones which are jellybean , kitkat and lollipop . My friend's, which is 6.0 , does not work ... the map of GOOGLE API, yes, appears, but the coordinates do not appear, as if he had not put anything, only the map...

Because ? Where does it fail?

Clarification : If you are thinking of telling me to try MapFragmentthe application stops me, so that is not the solution, MapFragmentinstead of SupportMapFragmentit does not work for me in any situation, and what is implemented here below works:

public class Map_fragment extends Fragment implements OnMapReadyCallback {

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.activity_map, container, false);

    SupportMapFragment mapFragment = (SupportMapFragment) this.getChildFragmentManager().findFragmentById(R.id.mapid);
    mapFragment.getMapAsync(this);

    return v;
}

@Override
public void onMapReady(GoogleMap map) {
    LatLng RudeBoys = new LatLng(39.4561165, -0.3545661);

<fragment

I have implemented BottomBarwith 5 Fragmentswhere I have in one of them a WebViewwith the Youtube page . The problem is that when I play a video and change from Fragmentto BottomBarit is still heard, and it should stop.

I have tried with the method onPause, but nothing. The method onStop, I don't know why the application stops. Which one should be used in this case?

public class Four_fragment extends Fragment {

    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.four_tab, container, false);

        String url = "https://www.youtube.com/";
        WebView appWeb = (WebView) v.findViewById(R.id.webView);
        //Habilitamos el javaScript y el zoom
        appWeb.getSettings().setJavaScriptEnabled(true);
        appWeb.getSettings().setBuiltInZoomControls(true);
        //Cargamos el enlace definido
        appWeb.loadUrl(url);
        //Este método es para que el navegador se quede en nuestra aplicación
        appWeb.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                return false;
            }
        });
        return v;
    }
}

I have a type Fragment, where I have implemented a ListViewwith certain characters. It turns out that I had the typical blue bar above with the name of the App and through manifestit I have removed it but I cannot take advantage of its space, that is, it does not reach the ListViewtop, only until the beginning of the supposed top bar, and It takes up a lot of space.

Is it possible to deactivate it completely to be able to take advantage of the whole screen?

Another thing you can see is the BottomBarbottom one, red, since the typical Android buttons are there, it starts higher, is there any way to lower it or adapt it to the buttons even more?

UPDATED:

activity_main.xml

< LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

xmlns:app="http://schemas.android.com/apk/res-auto"

android:orientation="vertical"

android:layout_height="match_parent">

<FrameLayout

    android:id="@+id/frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

I have the following function to save data in a database, where "SaveData" is the onClick method of my button, but I want it to disable the button after clicking 1 time on it, to avoid saving all the time, my function is this one and I thought it was done with the onclicklistener thing but I see that it's not...:

public void GuardarDatos(View view) {

    int primero = Integer.parseInt(Primero1.getText().toString());
    finalizar =(ImageButton) findViewById(R.id.Guardar) ;

    BaseHelper baseHelper = new BaseHelper (this,"DEMODB",null,1);
    SQLiteDatabase db = baseHelper.getWritableDatabase();

    if(db!=null){

        ContentValues registronuevo = new ContentValues();

        registronuevo.put("Primero",primero);

        long i = db.insert("Notas",null,registronuevo);
        if ( i>0)
            Toast.makeText(this,"Puntuación guardada",Toast.LENGTH_SHORT).show();

        finalizar.setOnClickListener(new View.OnClickListener() {
            @Override   
            public void onClick(View v){
                onStop();  //Se supone que esto basta pero no. No funciona
            }
        });
    }

}

UPDATE:

finalizar = (ImageButton) findViewById(R.id.Guardar);

     finalizar.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View view) {
                //ejecuta el método
                GuardarDatos(); // --> Aquí me obliga a pasarle algo , 
                               // pone : The method GuardarDatos(View) in the type Tiempoacabadobebe is not applicable for the arguments () 
                //Deshabilita el botón
                finalizar.setEnabled(false); 
            }

        });

I have an Android application that takes up a lot of my time and 90% of the total is due to 3 files that I don't know if they can be deleted or what would happen if I delete them.

The first is fileSnapShots.bin, located in .gradle/2.10/taskArtifacts , it is 22 MB, what happens if I delete it ? Can I do without it? It's very heavy...

The second and third are app-debug and app-debug-unaligned , located in app\build\outputs\apk , do they both work? 9MB between the two

The third one is mockable-android-23, located in \build\generated , I suppose this is useful to be able to run the app in android studio, but it weighs almost 23MB.

Can any of this be removed?
