How to save my app's settings?

Question

How do I save the back ground setting in the app and when it exits back it still saves that background As the default app I to be :

<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/bg2"
android:id="@+id/bgplayer">

and click button

 bgplayer.setBackgroundResource(R.drawable.bg1a);

If you want to completely exit the app and re-enter the background it will be bga1

This is very Bad coding practices. Don;t use that classes which has been deprecated. Ask your doubt with your effort. — coder_baba, Dec 08 '17 at 12:20

Use shared preferences in Activity:

SharedPreferences prefs = getSharedPreferences(
  "com.example.app", Context.MODE_PRIVATE);

then save like this:

prefs.edit().putInt("your_key", R.drawable.bg1a).apply();

and read like this:

int value = prefs.getInt("your_key", defaultIntValue);

And set background as:

bgplayer.setBackgroundResource(value);
