Android apps are software programs that run on the Android OS. They can be downloaded on Android tablets, phones and TVs. They are extremely adept in using the touchscreen, camera and GPS features of the device. The addition of numerous apps to an Android device can affect the battery’s life and performance.
Developing Android apps requires an understanding of the Android platform, including its design principles and frameworks. It also requires the implementation of an appropriate architecture for apps that is able to separate UI and OS-related code into pieces that share responsibility. These components can be activated through asynchronous communication with the system by the broadcast mechanism that is activated by intentions.
Java is the preferred language for Android development, though Kotlin has gained popularity in recent years. Both are supported by Android SDK. On the web, there’s an enormous group of developers who can help newcomers get used to the language and help with any issues.
The Android OS is divided into layers. The app layer includes the standard apps that come with the OS, and any apps that are proprietary and specifically designed for specific devices, such as a music player or a phone dialer. The Android application layer is comprised of customized firmware, such as CyanogenMod or OMFGB. These can be installed to modify the functionality of certain devices.
Compatibility is another aspect that stops certain apps from functioning. If an app was pushed out for the US market, but isn’t compatible with your European device, it will not be able to run on it and appear as “incompatible” in the Play Store.
