I want to save a flag for recognizing that my app is run for the first time or not. For this simple job I don't want to create database..

Is there a simple option to do this? I want to save and read little pieces of information only.

Use sharedPreference or files to save the data but better option is sharedPreference.

For Retrieving

SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
boolean silent = settings.getBoolean("silentMode", false);

For Saving 

SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putBoolean("silentMode", true);
editor.commit();
