Developing Android Apps

Android apps are software applications that run on the Android OS. They can be installed on Android tablets, phones and televisions. They are excellent at making use of the touchscreen, camera and GPS features of the device. The addition of numerous apps to an Android device can impact battery performance and life.

Understanding the Android platform and its design principles is vital to develop Android apps. It also involves the implementation of an appropriate architecture for apps that divides UI and OS-related code into parts which share responsibilities. These components can be activated in asynchronous fashion by the system via an event-driven broadcast mechanism, which is activated by intents.

Kotlin is gaining popularity as a programming language for Android development. Both are supported by the Android SDK. Online, there is a huge community of developers who help newcomers get used to the language and troubleshoot any problems.

The Android OS itself is divided into several layers, with the app layer containing the standard apps that ship with the operating system as well as proprietary apps bundled with a particular device like the music player or phone dialer. The Android app layer also includes customized firmware such as CyanogenMod and OMFGB, which can be installed on certain devices to alter their functionality.

Compatibility is a different factor that stops certain apps from functioning. If an app is created specifically for the US but not compatible with your European device, it will not run and will appear in the Play Store as “incompatible”.
