How to save data and re-open the last used Activity

Question

I\'ve made the majority of my game\'s mechanics, I now need to be able to:

1. Save all the data of the current activity and <

Answer 1

The onSaveInstanceState will not be called when you press back key to finish it. To save your data all the time you have to use onPause as the code shows:

@Override
public void onPause() {
    super.onPause();
    SharedPreferences sp = getSharedPreferences("X", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = sp.edit();
    editor.putString("lastActivity", HomeActivity.class.getCanonicalName());
}

Remember to replace HomeActivity with your own class name.BTW, I didn't test the function getCanonicalName, but it should work.

In your Dispatch Activity, you read the value back and do some action to it.
