Developing Android Apps

Android apps are software programs that run on the Android OS. They can be installed on Android phones, tablets and TVs. They are extremely adept in making use of the touchscreen, camera and GPS features on the device. Installing many apps on an Android device can affect the battery’s performance and life.

The process of creating Android apps requires an understanding of the Android platform, including its design principles and frameworks. It also requires an appropriate app architecture, which separates UIand OS-related code into components that share the same responsibilities. These components can be activated asynchronously by the system using a broadcast mechanism triggered by intentions.

Java is the preferred language for Android development, but Kotlin has gained a lot of attention in recent years. Both are supported by the Android SDK. A large developer community is available online to help newcomers to the language and troubleshoot problems.

The Android OS itself is divided into multiple layers, with the application layer comprising the standard apps that ship with the operating system, as well as proprietary apps that are bundled with a specific device like the phone dialer or music player. The Android application layer also has custom firmware such as CyanogenMod and OMFGB that can be installed on specific devices to modify their functions.

Compatibility is yet another factor which prevents some apps from functioning. If an app was launched to the US market but isn’t compatible with your European device, it will not be able to run on it and be marked as “incompatible” in the Play Store.
