Question

There is a lot of examples and guides how to get ApplicationContext, but a cannot find some examples which provide me an ability to store some values in ApplicationContext.
I want to get, for example, string mode everywhere in my application, like this:

String mode = getApplicationContext().getMode();

How can I do that?

Answer 1

You have to extend Application (there is no ApplicationContext class) and add the fields you need stored to your custom class. Then you would cast the reference you get from getApplication() to your actual class:

class MyApplication extends Application {
  String mode;
}

// in your activity
MyApplication app = (MyApplication)getApplication();
String mode = app.mode;
