Android apps are software applications that run on the Android OS. They can be downloaded on Android tablets, phones and televisions. They are extremely adept in using the camera, touchscreen and GPS features on the device. Installing a variety of apps on an Android device can negatively impact the battery’s performance and life.

Understanding the Android platform and its design principles is crucial for the development of Android apps. It also requires a proper app architecture that separates UI- and OS-related codes into components that have shared duties. These components can be activated asynchronously by the system using a broadcast mechanism that is triggered by desires.

Kotlin is growing in popularity as a language used in Android development. Both languages are supported by Android SDK. A large community of developers is available online to assist those who are new to the language and resolve issues.

The Android OS itself is divided into layers, with the app layer containing the standard apps that are included with the operating system, along with the specialized apps that are bundled with a specific device, like the phone dialer or music player. The Android app layer also includes custom firmwares, like CyanogenMod or OMFGB. These are installed to customize the functionality of certain devices.

Compatibility is another factor that hinders certain apps from working. If an app has been launched for the US market, but isn’t compatible with your European device, it will not function on it and will be marked as “incompatible” in the Play Store.
