Android apps are pieces of software that run the Android operating system. They can be installed on Android phones, tablets and televisions. They’re excellent at using the camera, touchscreen, and GPS features of the device. Installing many apps on an Android device can negatively impact battery performance and life.
In order to develop Android apps requires a deep understanding of the Android platform and its design principles and frameworks. It also involves creating an appropriate app architecture that is able to separate UI and OS-related code into components which share responsibilities. These components can be activated asynchronously by the system using a broadcast mechanism that is triggered by intentions.
Kotlin is becoming more popular as a programming language for Android development. Both are supported by the Android SDK. Online, there is an extensive group of developers who can help newcomers learn the language and troubleshoot any issues.
The Android OS itself is divided into multiple layers, with the application layer containing the standard applications that come with the operating system as well as the custom apps bundled with a particular device such as the phone dialer or music player. The Android app layer also includes custom firmware, like CyanogenMod or OMFGB. These can be installed to customize the functionality of specific devices.
Compatibility is yet another factor which prevents some apps from working. If an app was released for the US market but isn’t compatible with your European device, it will not work on it and will be displayed as „incompatible“ in the Play Store.
