Developing Android Apps

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

Making Android apps requires an understanding of the Android platform and its design principles and frameworks. It also requires a proper app architecture that separates UIand OS-related code into components that have shared responsibilities. The system is able to activate these components asynchronously by using an asynchronous broadcast mechanism that is activated by the intents.

Kotlin is gaining popularity as a language that is used for Android development. Both languages are supported by Android SDK. A large developer community is available online to help newcomers to the language understand and solve issues.

The Android OS itself is divided into several layers, with the app layer consisting of the default apps that ship with the operating system, as well as the custom apps bundled with a particular device like the phone dialer or music player. The Android application layer also has custom firmware, such as CyanogenMod and OMFGB which can be installed on specific devices to alter their functionality.

Another reason that blocks certain apps from functioning is compatibility. If an app was pushed out for the US market but isn’t compatible with your European device, it won’t work on it, and will appear as “incompatible” in the Play Store.
