Question

I have been spending the last few hours researching on how to store data within internal storage however I cannot for some reason be capable of storing an integer.

I would like to know how to store an int value within a file as well as be able to read off of it.
Please provide a brief example on how I can achieve this and would it be preferable to use the SharedPreferences class?

Answer 1

It is better to use SharedPreference if it is just an int value:

public int getValue() {
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
    return prefs.getInt("value_key", 0);
}

public void setValue(int newValue) {
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
    SharedPreferences.Editor editor = prefs.edit();
    editor.putInt("value_key", newValue);
    editor.commit();
}
