Android apps are pieces of software that run the Android operating system. They can be installed on Android tablets, TVs and phones. They are extremely adept at using the touchscreen, camera and GPS features of the device. There are a lot of apps installed on an Android phone however, could affect the life of batteries and performance.
Understanding the Android platform and its design principles is essential in the creation of Android apps. It also requires implementing an appropriate app architecture that is able to separate UI and OS-related code into components which share responsibilities. The system can activate these components asynchronously through an asynchronous broadcast mechanism that is activated by intentions.
Kotlin is gaining traction as a language for Android development. Both languages are supported by Android SDK. On the internet, there is a large community of developers who assist newcomers to understand the language and troubleshoot any problems.
The Android OS is divided into layers. The application layer comprises the standard apps that are included with the OS, in addition to any custom apps that come specifically designed for specific devices, for example, a music player see this or a phone dialer. The Android app layer includes custom firmwares, like CyanogenMod or OMFGB. These are installed to customize the functionality of certain devices.
Another reason that blocks certain apps from functioning is compatibility. If an app was launched for the US market but isn’t compatible with your European device, it will not work on it and will appear as “incompatible” in the Play Store.
