Answer 1

The following works for me:

private static String KEY_FIRST_RUN = "";
private SharedPreferences sharedPreferences;
private SharedPreferences.Editor editor;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    sharedPreferences = getPreferences(MODE_PRIVATE);

    if (!sharedPreferences.contains("KEY_FIRST_RUN")) {
        KEY_FIRST_RUN = "something";
        Log.d("First", "First run!");
    } else {
        Log.d("Second...", "Second run...!");
    }

    editor = sharedPreferences.edit();
    editor.putString("KEY_FIRST_RUN", KEY_FIRST_RUN);
    editor.commit();
}
