Using Application context everywhere?

Question

In an Android app, is there anything wrong with the following approach:

public class MyApp extends android.app.Application {

    private static MyApp instan         


        

Answer 1

It is a good approach. I use it myself as well. I would only suggest to override onCreate to set the singleton instead of using a constructor.

And since you mentioned SQLiteOpenHelper: In onCreate () you can open the database as well.

Personally I think the documentation got it wrong in saying that There is normally no need to subclass Application. I think the opposite is true: You should always subclass Application.
