SharedPreferences from different activity

Question

I load from activity A the SharedPreferences in following way:

private void SavePreferences(String key, String value){
    SharedPreferences sharedPreference         


        

Answer 1

use getApplicationContext() instead of this in both Activities as:

In activity A the SharedPreferences in following way:

 private void SavePreferences(String key, String value){
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());

        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putString(key, value);
        editor.commit();
        Intent sd=new Intent(this,Secongtess.class);
        startActivity(sd);
       }

and in Activity B get Value as:

 private void LoadPreferences(){   
       SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
     String  data = sharedPreferences.getString("name", "08:00") ;
     Toast.makeText(this,data, Toast.LENGTH_LONG).show();
   }

because as doc says:

getDefaultSharedPreferences(Context context) :

Gets a SharedPreferences instance that points to the default file that is used by the preference framework in the given context.
