Testing and Debugging
Writing tests to verify that the application's logic and user interface are performing as expected, and executing those tests using the developer tools. Candidates should be able to analyze application crashes, and find common bugs such as layout errors and memory leaks. This includes working with the debuggers to step through application code and verify expected behavior.

Given a problem description, replicate the failure
Use the system log to output debug information
Debug and fix an application crash (uncaught exception)
Debug and fix an activity lifecycle issue
Debug and fix an issue binding data to views
Application User Interface (UI) and User Experience (UX)
Implementation of the visual and navigational components of an application's design. This includes constructing layouts–using both XML and Java code–that consist of the standard framework UI elements as well as custom views. Candidates should have a working knowledge of using view styles and theme attributes to apply a consistent look and feel across an entire application. Understanding of how to include features that expand the application's audience through accessibility and localization may also be required.
Mock up the main screens and navigation flow of the application
Describe interactions between UI, background task, and data persistence
Construct a layout using XML or Java code
Create a custom view class and add it to a layout
Implement a custom application theme
Apply a custom style to a group of common widgets
Define a RecyclerView item list
Bind local data to a RecyclerView list
Implement menu-based or drawer navigation

Apply content descriptions to views for accessibility
Add accessibility hooks to a custom view
Fundamental Application Components
Understanding of Android's top-level application components (Activity, Service, Broadcast Receiver, Content Provider) and the lifecycle associated with each one. Candidates should be able to describe the types of application logic that would be best suited for each component, and whether that component is executing in the foreground or in the background. This includes strategies for determining how and when to execute background work.
- Describe an application's key functional and nonfunctional requirements
- Create an Activity that displays a layout resource
- Schedule a time-sensitive task using alarms
- Schedule a background task using JobScheduler
- Execute a background task inside of a Service
- Implement non-standard task stack navigation (deep links)
- Integrate code from an external support library
Persistent Data Storage
Determining appropriate use cases for local persisted data, and designing solutions to implement data storage using files, preferences, and databases. This includes implementing strategies for bundling static data with applications, caching data from remote sources, and managing user-generated private data. Candidates should also be able to describe platform features that allow applications to store data securely and share that data with other applications in a secure manner.
- Define a database schema; include tables, fields, and indices
- Create an application-private database file
- Construct database queries returning single results
- Construct database queries returning multiple results
- Insert new items into a database
- Update or delete existing items in a database
- Expose a database to other applications via Content Provider
- Read and parse raw resources or asset files
- Create persistent preference data from user input
- Toggle application logic based on preference values
Enhanced System Integration
Extending applications to integrate with interfaces outside the core application experience through notifications and app widgets. This includes displaying information to the user through these elements and keeping that information up to date. Candidates should also understand how to provide proper navigation from these external interfaces into the application's main task, including appropriate handling of deep links.
- Create an app widget that displays on the device home screen
- Implement a task to update the app widget periodically
- Create and display a notification to the user
App Data and Files (Android Architecture Components)
Android architecture components are part of Android Jetpack. They are a collection of libraries that help you design robust, testable, and maintainable apps. Start with classes for managing your UI component lifecycle and handling data persistence.
Manage your app's lifecycle with ease. New lifecycle-aware components help you manage your activity and fragment lifecycles. Survive configuration changes, avoid memory leaks and easily load data into your UI.
Use LiveData to build data objects that notify views when the underlying database changes
ViewModel Stores UI-related data that isn't destroyed on app rotations. Note it doesn't replace savedInstanceState
Room is an a SQLite object mapping library. Use it to Avoid boilerplate code and easily convert SQLite table data to Java objects. Room provides compile time checks of SQLite statements and can return RxJava, Flowable and LiveData observables. Android Developers Page
