Question

Hello I have an app that I'm developing and I want to clear all of its data when its getting close. I don't mind if it will need to add permission or something like this. also I need it will clear all of my shared preferences.

Answer 1

you can use this code for delete all data from sharedpreferences.

this is for clear data when apps close:-

 @Override
public void onDestroy() {
super.onDestroy(); 
SharedPreferences preferences = getSharedPreferences("your prefre name", 0);
 preferences.edit().clear().commit();
}

this is when you want to clear all data by any your activity like as button clicked:-

    SharedPreferences preferences = getSharedPreferences("your prefre name", 0);
    preferences.edit().clear().commit(); 

it should solve your query.

Answer 2
