Developing Android Apps

Android apps are software programs that run on the Android OS. They can be downloaded on Android tablets, phones, and televisions. They are excellent at using the camera, touchscreen, and GPS features on the device. Installing many apps on an Android device can impact the battery’s performance and life.

Making Android apps requires a thorough understanding of the Android platform and its design principles and frameworks. It also means the implementation of an appropriate architecture for apps that separates UI and OS-related code into pieces which share responsibilities. The system can trigger these components asynchronously through an asynchronous broadcast mechanism that is activated by intentions.

Java is the preferred language for Android development, although Kotlin has gained a lot of attention in recent years. Both are supported by the Android SDK. A large community of developers is available online to assist newcomers to the language understand and solve issues.

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

Another reason that blocks certain apps from functioning is compatibility. If an app was designed specifically for the US but is not compatible with your European device it will not function and will be displayed in the Play Store as “incompatible”.
