Android Core: This section requires that the individuals have an understanding of Android system’s architecture and be able to explain the fundamental building blocks of the Android app. They also need to possess a good comprehension of the process required to develop, build, and run an Android application as well as be capable of displaying basic messages in a pop-up with the use of a ‘Toast’ or a ‘Snackbar’. The test takers should possess the skills in displaying messages outside the UI of an app with the use of ‘Notification’ and schedule background tasks with the use of ‘WorkManager’. Additionally, they should understand the process of localizing an app.
User Interface: This part requires that the applicants have an understanding of the activity lifecycle of Android. They should also be capable of creating an ‘Activity’ that shows a ‘Layout’ as well as constructing a UI using ‘ConstraintLayout’. The section also requires an understanding of how to build a custom ‘View’ class and include it to a ‘Layout’; familiarity with the process of implementing custom app themes and including accessibility hooks to the custom ‘View’. Additionally, the students should also understand how to apply the content descriptions to a view for accessibility. It is also important to understand the process of displaying items in a ‘RecyclerView’ and have the capacity to bind local data to the ‘RecyclerView’ list with the use of the Paging library. They should be able to implement both menu-based and drawer navigation.
Data Management: This topic measures the learners’ skills in defining data with the use of Room entities; accessing ‘Room’ database using a data access object; observing and responding to changing data with the use of ‘LiveData’. The applicants should also have competence in reading and parsing asset files or raw resources; using a Repository for mediating data operations; creating persistent Preference data from the user input; changing behaviors of an app based on the user preferences.
Debugging: This domain will evaluate your understanding of the fundamental debugging methods that are available within Android Studio. It will also measure the skills required for debugging and fixing issues associated with the usability and functional behavior of an app as well as the skills in using System Log to output the debug information. This section of the exam also requires an understanding of the process involved in using breakpoints in Android Studio and inspecting variables with the use of Android Studio.
Testing: This area requires a thorough understanding of the fundamentals of testing and the ability to write the functional local JUnit tests. It will also measure the understanding of the Espresso UI test framework as well as the skills in writing the functional automated Android tests.
