Question

android, java, sharedpreferences, datad during the run . What I want is that if I close or pause my app the ints value are saved, so when I open it back again I can have the last value back.

I have this so far, trying with 1 int to learn how to.

protected void onPause(){
    SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
    SharedPreferences.Editor editor = settings.edit(); 
    editor.putInt("valueSave",valueToSave ); 
    editor.commit();
} 

@Override 
protected void onResume(){
    SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0); 
}

But values are not saved… what am I doing wrong?

EDIT: onCreate added

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.program);
    //SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
    SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
    //settings = getSharedPreferences(PREFS_NAME, 0);
    valueToSave = settings.getInt("valueSave",valueToSave);

Answer 1

Try getting a SharedPreference using the application context in this way:

To save preferences:

int valueToSave = 1;
SharedPreferences.Editor editor = PreferenceManager.getDefaultSharedPreferences(getApplicationContext()).edit();
editor.putInt("someValue", valueToSave);
editor.commit();

To retreive from preferences:

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
int savedvalue = settings.getInt("someValue");
