Developing Android Apps

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

Making Android apps requires a deep understanding of the Android platform as well as its design principles and frameworks. It is also about the implementation of an appropriate architecture for apps that divides UI and OS-related code into pieces which share responsibilities. These components can be activated through asynchronous communication with the system by a broadcast mechanism triggered by desires.

Java is the preferred language for Android development, although Kotlin has gained a lot of attention in recent years. Both are supported by Android SDK. Online, there is an extensive community of developers who help newcomers learn the language and solve any problems.

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 apps bundled with a particular device, like the phone dialer or music player. The Android app layer also includes custom firmwares, like CyanogenMod or OMFGB. These can be installed to customize the functionality of specific devices.

Compatibility is another aspect which prevents some apps from functioning. If an app has been released for the US market but isn’t compatible with your European device, it won’t work on it and will appear as “incompatible” in the Play Store.
