I generate the UUID but the problem is that when I close the app and run it again he generate another UUID, I want to generate UUID just for one time, and keep it always the same after installing the application.
private final static String androidId = UUID.randomUUID().toString();

reference to Công Hải's comment ,I used SharedPreference and it work perfectly:
private static String uuid;
SharedPreferences sPrefs = PreferenceManager.getDefaultSharedPreferences(this);
uuid = sPrefs.getString("uuid",null);
if (uuid == null){
uuid = UUID.randomUUID().toString();
SharedPreferences.Editor editor = sPrefs.edit();
editor.putString("uuid",uuid);
editor.apply();
}
