Syllabus
The whole syllabus is divided into few sections:
Android Core
This section involves the basics of Android system architecture, XML files, virtual machine, Activities, Services, Content Providers, Intents, Broadcast Receiver properties, manifest file significance, creating components, and using the predefined structure for creating a basic android application.
With basic android core knowledge you can use Toast, Snackbar, Notifications, scheduling background tasks using WorkManager, etc for displaying texts in the application. One of the most important topics in this section is knowing the lifecycle of the android application threads.
Mostly this section deals with the usage of UI in applications that Android studio provides a variety of supports to build seamlessly and efficiently. You can also get some idea about android features as it provides some latest up-gradation and features.
·User Interface
Android framework enables us to develop useful applications efficiently with a smooth User Interface. One needs basic knowledge of views, Layouts and, activity lifecycle to understand how the UI layer works. Some of the most important subcategories that you need to refer to in this section are – Activity, Activity lifecycle, Constraint, and Relative layouts, View class, RecyclerView, paging library to make the scrolling of the recycler view smooth where the data is locally bound with the views.
If paging is not used then, the User Interface will feel stuck/lagged. Implementation for menu-based navigation and drawer navigation is important as the exam is concerned.
- Create custom views
- Build accessible and reusable views
- Using material components
- Activities and intents
- Creating custom Recycler views and adapters
Data Management
Data is an important aspect of any application. Proper data management techniques are required to essentially make the application more reliable and useful. The candidate must have a basic knowledge of the Data Access Object (DAO) layer to be able to use the Room database where the user data can be stored.
Real-time data can be observed and responded to with LiveData. Taking care of the user input and asset files provided by the user is also necessary.
- Room with a view
- Repository for accessing DAO layer
- ViewModelo Drawables, styles, and themes
Debugging
Debugging is one of the most important parts of any development process. While creating applications, it is obvious that there have been some errors, and fixing these issues is known as debugging. A candidate must have the ability to find the error and fix the issues in their android applications.
This will include having knowledge of error statements, System logs, adding breakpoints to test the applications statement by statement.
- Debug your app
- Write logs with logcato
- Using android studio debugger to find and fix errors
Testing
Testing is the process of finding the last lines of errors like if a particular function is providing efficiently some unexpected output or not. This is quite similar to debugging, but most of the errors are quite hard to catch as these do not give any error statements.
Testing is done to find errors, abnormal or unexpected behaviour in the android application. Testing and test-driven development (TDD) is a critically important step of software development for every Android Developer. If you are already a developer then you might be knowing about unit testing.
Some of the most important topics to learn for this section:
- Basic knowledge of using Junit tests
- Understanding the Espresso UI test framework
- Writing automated android tests
