The Associate Android Developer Exam will ask you to demonstrate skills in the following areas:
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.
Write and execute a local JVM unit test
Write and execute a device UI test
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
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
Localize the application's UI text into one other language
Apply content descriptions to views for accessibility
Add accessibility hooks to a custom view
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
Fetch local data from disk using a Loader on a background thread
Propagate data changes through a Loader to the UI
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
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
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
The exam is performance-based and designed to evaluate what you can do, show, and describe. You will be given a coding project based on a starter app. In this project, you will be asked to add functionality and fix bugs. The type of functionality you are asked to add and the bugs you are asked to find and fix fall under the competencies listed above in "What does the exam cover?".
The Associate Android Developer Certification exam is $149 USD. Local pricing may vary based on your country of origin.
The Associate Android Developer Certification process works like this:
Complete the registration process and pay for, download, and complete your exam.
After you complete the exam, you will submit it for grading.
Immediately following submission you will be asked to verify your identity. Please have your government-issued ID (driver's license, passport, etc.) ready.
If you passed the exam, you will be able to set up your exit interview. This will be a chance for you to explain your work, and you'll once again provide proof of your identity.
Upon successfully passing the exit interview, you will be awarded with your Associate Android Developer Certification.
Note: Exams will be graded in the order that they are submitted. Due to the in-person nature of the exit interview portion, the awarding of certifications will depend on when you are able to complete your interview. It is our intention to review completed exam submissions and reply to candidates within 45 days.
When you are ready to start, you will sign up and pay to take the exam. You have 48 hours from the time you receive your exam until the time you must submit it. If you do not submit your exam within 48 hours, your attempt will count as "failed" and you will need to take another exam to proceed with the certification process.
If a candidate does not pass the Certification exam, they may retake it in the following manner:
If a candidate does not pass their first attempt, they may immediately retake the exam.
If a candidate does not pass their second attempt, they will be eligible for their third attempt after a two month period.
If after three attempts, the candidate has still not passed the exam, they must wait six months. After six months, if the candidate still wishes to take the exam, they must pay for the exam to take it again.
Make sure you have an acceptable form of ID. Acceptable forms of ID include driver's licenses, passports, or a government-issued ID. Note: student or work IDs are not accepted.
Make sure the image and/or ID you upload is clear and not blurry. Do not obstruct your ID with your fingers if you are using a webcam.
