Android apps are software applications that run on the Android OS. They can be downloaded on Android tablets, phones and televisions. They are very good in making use of the touchscreen, camera and GPS functions on the device. Installing many apps on an Android device can impact battery life and performance.

Making Android apps requires a deep understanding of the Android platform, including its design principles and frameworks. It also involves developing an appropriate app architecture that divides UI and OS-related code into parts that share responsibility. The system can activate these components asynchronously through the broadcast mechanism, which is triggered by intentions.

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

The Android OS itself is divided into layers, with the application layer comprising the standard apps that come with the operating system and also the proprietary apps that are bundled with a specific device, like the music player or phone dialer. The Android app layer also includes custom firmwares, like CyanogenMod or OMFGB. They can be installed to customize the functionality of certain devices.

Another reason that stops certain apps from working is compatibility. If an app was pushed out to the US market but is not compatible with your European device, it will not function on it and will be displayed as “incompatible” in the Play Store.
