Question

I have to create a small android application for my college course work which presents 10 maths problems and take answers from users to calculate the score.

The program is supposed to have a main screen with “new game” button and a “continue” button.

How do I program to save data during the application run and retrieve them from the stored place to continue from that point if the user presses continue button? (what sort of a method I should be looking at for such a task? )

Thanks in advance.

Just use preference to store and retrieve value in the code.Here is the snippet

//Set Preference
SharedPreferences myPrefs = getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
SharedPreferences.Editor prefsEditor;  
prefsEditor = myPrefs.edit();  
prefsEditor.putString("REFKEY", valuetobestored);
prefsEditor.commit();

//Get Preferenece  
SharedPreferences myPrefs;  
myPrefs = getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
String output=myPrefs.getString("REFKEY", "");
