//
private static final String TAG = App.class.getSimpleName();
public static SharedPreferences sPrefs;
private static App sInstance;

public static App getsInstance() {
    return sInstance;
}

@Override
public void onCreate() {
    super.onCreate();
    if (!BuildConfig.DEBUG) {
        Fabric.with(this, new Crashlytics());
    }
    Log.e(TAG,"onCreate()");
    sInstance = this;
    sPrefs = PreferenceManager.getDefaultSharedPreferences(this);
}
//some methods
}

in AndroidManifest.xml

<application
    android:name=".App"
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
