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 functions on the device. Installing a variety of apps on an Android device can negatively impact the battery’s performance and life.
In order to develop Android apps requires a deep understanding of the Android platform as well as its design principles and frameworks. It is also about developing an appropriate app architecture that can be separated from UI and OS-related code into parts which share responsibilities. These components can be activated at a time that is synchronized by the system, using the broadcast mechanism that is activated by the intents.
Kotlin is becoming more popular as a programming language for Android development.

The Android OS itself is divided into multiple layers, with the application layer comprising the standard apps that are included with the operating system, and also the proprietary apps bundled with a particular device, like the phone dialer or music player. The Android application layer comes with custom firmware, such as CyanogenMod or OMFGB. These can be installed to customize the functionality of specific devices.
Compatibility is a different factor that hinders certain apps from working. If an application is created specifically for the US but is not compatible with your European device it will not work and will be listed in the Play Store as “incompatible”.
