Android apps are bits of software that run the Android operating system. They can be installed on Android tablets, TVs and phones. They’re extremely efficient in using the camera, touchscreen and GPS capabilities of the device. Having lots of apps installed on an Android phone however, could affect battery life and performance.
Making Android apps requires a deep understanding of the Android platform and its design principles and frameworks. It is also about creating an appropriate app architecture that divides UI and OS-related code into components which share responsibilities. These components can be activated through asynchronous communication with the system by an event-driven broadcast mechanism, which is activated by intents.
Java is the preferred language for Android development, however Kotlin has gained a lot of attention in recent years. Both are supported by Android SDK. A large community of developers is available online to help those who are new to the language and fix issues.

The Android application layer is comprised of customized firmware, such as CyanogenMod or OMFGB. These are installed to alter the functions of specific devices.
Another factor that prevents some apps from working is compatibility. If an app was designed for the US but is not compatible with your European device it will not work and be displayed in the Play Store as “incompatible”.
