How to get the device locale after changing the application locale

Question

I am changing the application locale based on user choice. Independent of device locale.

using

public void setDefaultLocale(Context context, String          


        

Answer 1

If you need to support below Android 7.0 - Nougat (API level 24) you can use something like this:

@SuppressWarnings("deprecation")
@SuppressLint("NewApi")
// ToDo: Adjust this method once the target API is 24 or higher!
private Locale getLocale()
{
  if(Build.VERSION.SDK_INT >= 24)
  {
    return Resources.getSystem().getConfiguration().getLocales().get(0);
  }

  else
  {
    return Resources.getSystem().getConfiguration().locale;
  }
}

Note the annotation regarding deprecation and NewApi. Adjust this method once you target API 24 or higher. Inspired by this answer.

Answer 2

I asked something similar and found this answer, sorry if it is late:

To find the system locale use:

defaultLocale = Resources.getSystem().getConfiguration().locale;

It gets the system locale, no matter which default locale is set for the app/activity.

Answer 3

I am absolutely unsure how portable this is to different devices:

try {
    Process exec = Runtime.getRuntime().exec(new String[]{"getprop", "persist.sys.language"});
    String locale = new BufferedReader(new InputStreamReader(exec.getInputStream())).readLine();
    exec.destroy();
    Log.e("", "Device locale: "+locale);
} catch (IOException e) {
    e.printStackTrace();
}

And if you want the country part: persist.sys.country

Answer 4

for those whom are using Daniel Fekete 's solution which is :

Process exec = Runtime.getRuntime().exec(new String[]{"getprop", "persist.sys.language"});
String locale = new BufferedReader(new InputStreamReader(exec.getInputStream())).readLine();
exec.destroy();

Be aware of that locale might be EMPTY on latest Android Api(+21)! instead of using persist.sys.language use persist.sys.locale

exec = Runtime.getRuntime().exec(new String[]{"getprop", "persist.sys.locale"});
locale = new BufferedReader(new InputStreamReader(exec.getInputStream())).readLine();
exec.destroy();
