How to open maps app with a specific GPS position on Android?

  • 772

I have the url https://www.google.com/maps/@41.3825581,2.1704375,16zthat positions Barcelona on the map, but I find that the address pointer does not come out, it only centers the map.

On my device I have several map apps:

  • Cytymapper
  • MAPS.ME
  • Google Maps
  • Google Earth

The code I have to launch the Intent:

Uri uri = Uri.parse("https://www.google.com/maps/@41.3825581,2.1704375,16z");
if (URLUtil.isValidUrl(uri.toString())) {
   startActivity( new Intent(Intent.ACTION_VIEW, uri));
}

I get a ActionListto choose Mapsor Chrome, if MapsI click on the application opens maps, but it does not show me the position with an indicator, it focuses on landmark and point.

If I indicate that it opens with chrome, another appears ActionList, with the other map applications.

My doubts are:

  • How do I launch a Intentspecific so that it can be opened with the Maps Apps?
  • How can I display the position marker within the map?

Fixed:

To display a location with marker and label

geo:<lat>,<lon>?z=<zoom>&q=<lat>,<lon>(<label>)

To show the location of Barcelona

geo:41.3825581,2.1704375?z=16&q=41.3825581,2.1704375(Barcelona)

To show the ActionListoutput of all compatible applications to position a location

Uri uri = Uri.parse("geo:41.3825581,2.1704375?z=16&q=41.3825581,2.1704375(Barcelona)");
startActivity( new Intent(Intent.ACTION_VIEW, uri));

If you want to send the position directly to the Google Maps application

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse("geo:41.3825581,2.1704375?z=16&q=41.3825581,2.1704375(Barcelona)"));
                intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
                startActivity(intent);
java

    According to this answer on SO in English:

    The form is this:

    Uri intentUri = Uri.parse("geo:41.382,2.170?z=16&q=41.382,2.170(Esta+Es+La+Etiqueta)");
Intent intent = new Intent(Intent.ACTION_VIEW, intentUri);
startActivity(intent);

  2. You can do it like this:

    map.moveCamera( CameraUpdateFactory.newLatLngZoom(new LatLng(xxxx,xxxx) , 14.0f) );

    The xxxx represent latitude and longitude and 14.0f the zoom level.

    How can I display the position marker within the map?

    I don't know if there is a better way to do what you ask, but if I understand your question you can try some of the following examples, if it is what you are looking for you could implement it in some way in your app, if you can't get the coordinates in the following Act , I could pass them inside the Intent and retrieve them there.

    // latitude longitude

double latitude = 41;
double longitude = 2;

// marker
MarkerOptions miMarker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("Hola Webserveis");

// marker icono
miMarker.icon(BitmapDescriptorFactory.fromResource(R.drawable.mimarkericono)));

// marker
googleMap.addMarker(miMarker);

    @Override
public void onMapReady(GoogleMap map) {
    map.addMarker(new MarkerOptions()
        .position(new LatLng(10, 10))
        .title("Hola Webserveis"));
}

    How do I launch a specific Intent so that it can be opened by Maps Apps?

    About the part that says how to open an app with an Intent, I don't know if this is what you mean:

    Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?saddr="+_lat+","+_ltg+"&daddr="+destino_lat+","+destino_ltg)); //o la direccion/consulta que quiera "http://maps.google.com/maps?q="+ myLatitude  +"," + myLongitude +"("+ labLocation + ")&iwloc=A&hl=es"
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(intent);
