Answer 1

You are using getPreferences(MODE). Use getSharedPreferences("PREF_NAME", MODE) instead. This way you will provide a name to particular preference and then you can call it by its name (PREF_NAME here) from whatever the activity you want.

//------get sharedPreferences

SharedPreferences pref = context.getSharedPreferences("PREF_NAME", Context.MODE_PRIVATE);

//-------get a value from them

pref.getString("NAME", "Android");

//--------modify the value

pref.edit().putString("NAME", "Simone").commit();

//--------reset preferences

pref.edit().clear().commit();
