Developing Android Apps

Android apps are pieces of software that run the Android operating system. They can be downloaded on Android phones, tablets and TVs. They are excellent in making use of the touchscreen, camera and GPS features of the device. The presence of a lot of apps on an Android phone is, however, a problem that can impact battery life and performance.

Understanding the Android platform and its design principles is vital to develop Android applications. It also means creating an appropriate app architecture that is able to separate UI and OS-related code into components which share responsibilities. The system can trigger these components in asynchronous fashion using broadcast mechanisms that are triggered by intentions.

Kotlin is gaining popularity as a language used in Android development. Both languages are supported by the Android SDK. Online, there’s an enormous group of developers who can help newcomers learn the language and solve any issues.

The Android OS itself is divided into several layers, with the application layer comprising the default standard apps that ship with the operating system as well as the custom applications that are included with a particular device like the phone dialer or music player. The Android app layer also includes custom firmware, such as CyanogenMod and OMFGB, which can be installed on certain devices to modify their functionality.

Another reason that stops certain apps from functioning is compatibility. If an app has been made available for the US market but is not compatible with your European device, it won’t work on it, and will be marked as « incompatible » in the Play Store.
