Developing Android Apps

Developing Android Apps

Android apps are bits of software that run the Android operating system. They can be installed on Android phones, tablets and TVs. They’re very good at utilizing the camera, touchscreen, and GPS capabilities of the device. Having lots of apps installed on an Android phone, however, can affect battery life and performance.

Developing Android apps requires an understanding of the Android platform, including its design principles and frameworks. It also requires a well-designed structure for apps, which divides UI- and OS-related codes into components that have shared the same responsibilities. These components can be activated at a time that is synchronized by the system, using a broadcast mechanism that is triggered 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 online to help newcomers to the language understand and solve issues.

The Android OS itself is divided into layers, with the app layer comprising the standard applications that come with the operating system and also the proprietary apps that are bundled with a specific device, like the phone dialer or music player. The Android application layer also has custom firmwares, like CyanogenMod and OMFGB, which can be installed on certain devices to customize their functionality.

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