Developing Android Apps

Android apps are software applications that run on the Android OS. They can be downloaded on Android tablets, TVs, and phones. They are very good at using the camera, touchscreen and GPS features on the device. A lot of apps installed on an Android phone, however, can affect the life of batteries and performance.

Understanding the Android platform and its design principles is essential to develop Android applications. It also involves developing an appropriate app architecture that can be separated from UI and OS-related code into parts that share responsibility. These components can be activated through asynchronous communication with the system by an event-driven broadcast mechanism, which is activated by intents.

Kotlin is gaining traction as a language used in Android development. Both are supported by Android SDK. On the internet, there is an extensive community of developers who can help newcomers get used to the language and help with any issues.

The Android OS itself is divided into layers, with the application layer comprising the standard apps that are included with the operating system along with the specialized apps bundled with a particular device, such as the phone dialer or music player. The Android app layer also comes with custom firmware such as CyanogenMod and OMFGB which can be installed on specific devices to customize their functionality.

Another factor that prevents some apps from working is compatibility. If an app was released for the US market, but it’s not compatible with your European device, it will not function on it and will be displayed as “incompatible” in the Play Store.
