Android：如何仅显示一次应用内更新

Question

Is it possible to display the flexible in-app update only once using just the Google API? Eg.:

1. User opens the app.
2. There is a new version.
3. Display flexible in-app update dialog.
4. User cancels the dialog.
5. User opens the app again but the dialog is not shown.

Is it possible to achieve that with Google Core API or do I need to somehow store that information (that dialog was displayed but canceled) on my own?

Use a flag using shared preferences like below. Then check if the value has been edited before..if not app update

SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putBoolean("isAppUpdateShown", false);
editor.commit(); 

if(sharedPref.getBoolean("locked", false)){
//app update code
editor.putBoolean("isAppUpdateShown", true);

}
