Question

I am bit confused with how this shared preference works. I had a sample code from a website based on shared preferences. My problem is, editor.commit() doesn’t update immediately. Here is my sample code,

 public class PreferencesDemo extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    // Get the app's shared preferences
    SharedPreferences app_preferences = 
        PreferenceManager.getDefaultSharedPreferences(this);

    // Get the value for the run counter
    int counter = app_preferences.getInt("counter", 0);

    // Update the TextView
    TextView text = (TextView) findViewById(R.id.text);
    TextView text1 = (TextView) findViewById(R.id.text1);
    text.setText("This app has been started " + counter + " times.");

    // Increment the counter
    SharedPreferences.Editor editor = app_preferences.edit();
    editor.putInt("counter", counter+2);
  editor.apply();

    editor.commit(); // Very important
    text1.setText("This app has been started " + counter + " times.");
}

}

As you can see, I have counter whose value I am displaying in the first textView and after the commit statement I am printing the updated value in next TextView. But still both the textviews prints the same default value as ‘0’. So if I restart the app, both the textviews are updated.
How to solve this problem. Any help is appreciated.

try this
for store value in sharePreferences..

SharedPreferences prefs = getSharedPreferences("Share", Context.MODE_PRIVATE );
Editor editor = prefs.edit();
editor.putInt("Value", 1 );
editor.commit();

for get value

prefs.getInt("Value",0);
