Prevent locale changes on Android application

    public class MyApplication extends Application {

    @Override
    protected void attachBaseContext(Context base) {
        Resources res = base.getResources();

        Locale locale = new Locale("en");
        Locale.setDefault(locale);

        Configuration config = new Configuration();
        config.locale = locale;

        res.updateConfiguration(config, res.getDisplayMetrics());

        super.attachBaseContext(base);
    }
}

Support layout mirroring

<manifest>
    <application
        .
        .
        .
        android:supportsRtl="false"
        tools:replace="android:supportsRtl"
        >
    </application>
</manifest>
