Developing Android Apps

Sharing is Caring!

Android apps are software programs that run on the Android OS. They can be downloaded on Android tablets, phones and televisions. They’re very good at utilizing the camera, touchscreen, and GPS features of the device. Having lots of apps installed on an Android phone, however, can affect the life of batteries and performance.

Understanding the Android platform and its design principles is vital for the development of Android apps. It is also about creating an appropriate app architecture that can be separated from UI and OS-related code into pieces that share responsibilities. The system can trigger these components asynchronously using broadcast mechanisms that are activated by intents.

Kotlin is becoming more popular as a programming language for Android development. Both languages are supported by the Android SDK. A large developer community is online to help newcomers to the language and resolve issues.

The Android OS is divided into layers. The application layer comprises the standard apps included in the OS, as well as any custom apps that come specifically designed for specific devices, like the music player or phone dialer. The Android application layer also contains custom firmware such as CyanogenMod and OMFGB that can be installed on specific devices to alter their functionality.

Compatibility is another factor that stops certain apps from working. If an app is created specifically for the US but is not compatible with your European device, it will not work and be displayed in the Play Store as “incompatible”.
