Android apps are software programs that run on the Android OS. They can be downloaded on Android tablets, phones and TVs. They are extremely adept at using the camera, touchscreen, and GPS features on the device. Installing a variety of apps on an Android device can affect battery life and performance.
Understanding the Android platform and its design principles is crucial for the development of Android applications. It is also about developing an appropriate app architecture that divides UI and OS-related code into components that share responsibilities. These components can be activated at a time that is synchronized by the system, using an event-driven broadcast mechanism, which is activated by intents.

The Android OS itself is divided into multiple layers, with the app layer containing the standard apps that come with the operating system as well as proprietary apps that come with a specific device, such as the phone dialer or music player. The Android application layer comes with custom firmware, such as CyanogenMod or OMFGB. These are installed to modify the functionality of specific devices.
Another reason that hinders certain apps from functioning is compatibility. If an app has been pushed out to the US market, but it’s not compatible with your European device, it won’t function on it and will appear as « incompatible » in the Play Store.
