The Complete Intermediate Android Masterclass

Explore the four core Android building blocks—activities, services, content providers, and broadcast receivers—and learn to interact with underlying systems, starting with activities and delving into their granular details.

Android activities track user interactions, manage foreground lifecycle to keep processes running, prioritize data retention, preserve state across interruptions, and coordinate data flow between activities.

Discover why Android fragments enhance UI flexibility by enabling side-by-side views on large devices and single-activity control of reusable fragments.

Learn how to handle android configuration changes by using savedInstanceState to avoid recreating fragments. Retrieve existing fragments via fragment manager by id or tag when returning from a config change.

Explore communicating between fragments and activities by moving user interface elements into a fragment, implementing an on selected item listener interface, and attaching the listener in on attach.

Configure the border detail fragment to receive a serializable board object via arguments. Display the board name and description in text views and enable data passing through an interface listener.

Explore how content providers offer a common abstraction for sharing and consuming structured data, and use the content resolver and cursor to access data like contacts.

Configure Android Room by adding Room dependencies, and model a dream entity with an auto-generated id and columns for name and description, forming a simple database table.

Create an Android Room entity setup by converting content values into a dream object, map dream id and dream name fields, and refactor with private access to the keys.

Register the content provider in the manifest with a unique authority, define dream table contracts, and use a UriMatcher to handle all and single-dream queries.

Implement an android async task with doInBackground parameters and background work; insert data into a content provider using content values and a content resolver, then update the UI in onPostExecute.
