Problem with app_name texts in different languages

To solve this problem, it would be enough to make the app support several languages. For this you can take a look at the android documentation .

For your specific App name problem, you can do the following:

In your Manifest you must make use of the string resources, so that the device takes the corresponding language automatically, for this it is used @string/, remaining as follows:

<application
        android:name=".MyApp"
        android:icon="@drawable/logo"
        android:label="@string/app_name"
        android:theme="@style/AppTheme">

On the other hand, to add support for more languages, you'll need to create additional values ​​directories inside res/ that include a hyphen and the ISO language code at the end of the directory name. Like for example values-en , being as follows:

MyProject/
    res/
       values/
           strings.xml
       values-en/
           strings.xml

Finally you will have to add the string values ​​for each locale in the corresponding file. For example:

Spanish (default locale), /values/strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">Mi Aplicación</string>
</resources>

English, /values-en/strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">My Application</string>
</resources>

I hope it helps you

For that case you can use multilanguage support by defining a named string app_namein each strings.xml file defined for a different language.

 <string name="app_name">Mi Aplicación</string>

These texts in addition to the name of the application can be applied to others in the application.

Multilanguage support on Android

The localization scheme requires you to create folders and files containing the text and its identifier in different languages ​​as required, which will be supported by your application.

For example, if we suppose that our application supports English, Spanish and Romanian languages, we must have the following folders....

The default text folder would be:

res/values/strings.xml

The folder to add the texts in English:

res/values-en/strings.xml

would contain:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="nom">Crazy Dog</string>
    <string name="desc">Crazy dog Transportation, the best company</string>
</resources>

The folder to add the texts in Spanish is:

res/values-es/strings.xml

would contain:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="nom">Perro Loco</string>
    <string name="desc">Transportes Perro Loco, la mejor empresa</string>
</resources>

The folder to add the Romanian texts:

res/values-ro/strings.xml

would contain:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="nom">Câine nebun</string>
    <string name="desc">companie de transport Câine nebun, cea mai buna companie.</string>
</resources>

You would have something similar to this in your project:

You simply use those descriptions defined in your strings.xmlapplication wherever it is required in your application:

String strNombre = context.getResources().getString(R.string.nom);
textViewName.setText(strNombre);
String strDescripcion = context.getResources().getString(R.string.desc)  
textViewDesc.setText(strDescripcion);

strings.xmlThe great advantage is that automatically, depending on the language defined in your operating system, it loads the defined texts in the corresponding language file .
