Classes

ExampleApplication

The ExampleApplication class is a subclass of the Application class in Android. It enables strict mode by setting a thread policy that detects all violations, logs them, and causes the application to crash. It also maintains three mutable lists: leakedViews, leakedDialogs, and leakedServices. These lists are used to keep track of any views, dialogs, or services that are leaked during the application's lifecycle.
