  • Another thing that you need to keep in mind is to debug the Android application as it is one of the most important skills for any developer. Android Studio provides a debugger and allows you to do some of the most important things when you are building an Android app.

  • Learn about the navigation, back stack, and task. Building an Android requires you to develop a logical construct of the screens on which you want the user to navigate through.

  • Develop an understanding of Android Core. Using Handler, Looper and Handler Thread, you will be able to solve several problems in Android related asynchronous programming. These are helpful as complex Android structures are built on these languages as app developers in Dubai.

  • Start learning about Intent Service and Service. The latter one is used to perform background operations such as handling network transactions, playing music, and interacting with the content providers, and so on. It does not have a user interface.

  • Understand where you can consider using Array Map for improving the performance of your Android application.

  • Learn about tools which help in determining the CPU and memory usage along with other technical aspects of the application. Some of the metrics need to be evaluated continuously during the development of an Android application.

  • Learn about Android sensors, acceleration, MVP architecture and GPS.

  • Understand custom views as it an important aspect of Android development.

  • Learn more about Android Jetpack, which is used to develop an app faster. It is considered to be the next generation of Android components which combines the functionality of support library, backward compatibility and sending out immediate updates to a larger set of components. With this, you will be able to manage activities such as navigation, lifecycle management, background tasks so that you can focus more on what makes your app better. This package is designed to work well with Kotlin, thus saving you from writing more code.

  • Learn the use of proguard in Android application and optimize to reduce the size of the application.

  • Read and apply the security to build a secure Android application.

  • Get an understanding of bitmaps. Learning these takes a huge amount of memory, but when it is highly useful for the users who prefer well-formatted content that looks good in appearance.

  • Start reading out codes that are written by others to get a fair understanding of how things work and the ways in which you can improvise your knowledge and ensure that you are on the right path.
