Developing Android Apps

Android apps are software applications that run on the Android OS. They can be installed on Android TVs, tablets, and phones. They are very good in using the camera, touchscreen and GPS functions on the device. The addition of numerous apps to an Android device could affect the battery’s life and performance.

Understanding the Android platform and its design principles is essential to developing Android apps. It also requires an appropriate app architecture, which separates UI- and OS-related codes into components that have shared responsibilities. These components can be activated through asynchronous communication with the system by a broadcast mechanism that is triggered by intentions.

Java is the preferred language for Android development, but Kotlin has gained popularity in recent years. Both are supported by Android SDK. A large community of developers is online to help newcomers to the language and troubleshoot problems.

The Android OS itself is divided into layers, with the application layer consisting of the default applications that come with the operating system along with the specialized apps that are bundled with a specific device, like the music player or phone dialer. The Android application layer also has custom firmware such as CyanogenMod and OMFGB which can be installed on certain devices to customize their functionality.

Compatibility is a different factor that hinders certain apps from functioning. If an app was launched for the US market but is not compatible with your European device, it will not work on it and will be listed as “incompatible” in the Play Store.
