need to write a JUnit test for an already existing app which delas with life cycles of android methods. The test is to check the life cycle methods of the activity. The test should create an instance of the activity, check the values of the fields indicating the counts for the different life cycle methods, call the different life cycle methods and check that the fields have changed correctly. You should also destroy the activity and recreate it, checking that the values of the fields indicating the counts for the different life cycle methods have changed. Note that the method "callActivityOnDestroy" does not destroy your activity. Once we agreed on the job, I will send you the app.
