Android is an operating system that is prominently used in the smartphones these days. Launched by Google and a few other partner brands, there are a variety of features associated with android development that you should be aware of if you are planning to take up Android Development Courses. Being a popular option out of the available Mobile Development Courses, there are some key concepts of android app development that you should know before you start developing android apps.
User interface is an important area that the developers need to work around. Since the mobile phone screen is of an average size of 5 inches, one needs to understand that whatever you develop should fit perfectly on that screen. The building block that is used to work around the UI in android app development is known as activity. Just like there is an analogy in the window and dialogue between the desktop based applications, there is activity in the android applications. Right from constantly clicking on the screen while playing a game to tapping different buttons to reach at different pages, all of this is monitored and managed through activity in an android app.
An activity that is initiated by an application wouldn’t work like that forever and thus are short-lived in nature. So when the app shuts down, you still need something that ensures the backend processes keep running until the app is force closed. This task is managed with the help of services. Right from checking an update to playing music in the background, all of this and other advanced capabilities are handled by the services.
The next thing that you should know about the android development is to create platforms for data abstraction. When you use the content providers, they make sure that your application is able to abstract all the data that is available in the device and which has the permission of being accessible to all the apps in the phone. Obviously, you need to allow the app to access the data once that is done; the entire abstraction is done by the content providers. The model of the android app development is such that it would encourage you as a developer to share your apps data with other apps while you also have the permission to use theirs.
In addition to this, there are a lot of android features that are available at your disposal when you develop an app. Storage, connectivity, multimedia; GPS, network, etc. are some of these options.
Now that you have got your hands on the basics, you should know how to get started with android development. Generally, the application code is written in the java language itself as it becomes easy for the developers. There are different tools that are used to convert this java code into the android code, before it is run. Using any of the available JDK for this would serve your purpose of getting started with the android app development.
