Answer 1

you can use SharedPreferences simply.

for save :

SharedPreferences sp = getSharedPreferences("your_pref_key", Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.putString("your_key", yourValue);
editor.commit();

for read:

SharedPreferences sp = getSharedPreferences("your_pref_key", Activity.MODE_PRIVATE);
 String yourJson = sp.getString("your_key","defaultValue");

if you want deserialization, use gson

Gson gson = new Gson();  
YourClass yourObject = gson.fromJson(yourJson, YourClass.class);
