Summary

Tasks and Back Stack

• A task is a collection of activities the user interacts with
• When a new activity is started it is added to the back stack
• When the user goes back to the previous activity the top most activity is popped off the stack
• Back gesture at the root will default move the activity to the background
• In the background all activities and tasks are stopped but the backstack is maintained

UI tests with Espresso

• Espresso lets you record your interactions and use asserts to verify UI elements

Shared Preference

• A small collection of key-value pairs that can be saved and be used
• getSharedPreferences() - retrieves shared preference by name
• getPreferences() - is specific to the activity and doesn’t have to be named
