Android apps are software applications that run on the Android OS. They can be installed on Android devices like tablets, TVs and phones. They excel in making use of the touchscreen, camera and GPS features of the device. Installing many apps on an Android device can affect battery life and performance.
Developing Android apps requires a deep understanding of the Android platform, including its design principles and frameworks. It also requires a proper app architecture that separates UI- and OS-related codes into components that have shared the same responsibilities. These components can be activated through asynchronous communication with the system by a broadcast mechanism triggered by intentions.
Java is the preferred language for Android development, although Kotlin has gained a lot of attention in recent years. Both languages are supported by the Android SDK. A large developer community is online to help newcomers to the language and resolve issues.
