Developing Android Apps

Android apps are bits of software that run on the Android operating system. They can be installed on Android phones, tablets and TVs. They are extremely adept at using the touchscreen, camera and GPS functions of the device. Installing a variety of apps on an Android device can negatively impact battery performance and life.

Understanding the Android platform and its design principles is crucial for the development of Android applications. It also requires a proper app architecture that separates UIand OS-related code into components that have shared the same responsibilities. The system can activate these components asynchronously using a broadcast mechanism that is triggered by the intents.

Kotlin is becoming more popular as a programming language for Android development. Both are supported by the Android SDK. Online, there’s an enormous community of developers who help newcomers get used to the language and help with any issues.

The Android OS itself is divided into layers, with the application layer comprising the standard apps that ship with the operating system, as well as proprietary apps that come with a specific device, like the music player or phone dialer. The Android application layer is comprised of custom firmware, such as CyanogenMod or OMFGB. They can be installed to alter the functions of specific devices.

Another reason that hinders certain apps from functioning is compatibility. If an app has been launched to the US market, but isn’t compatible with your European device, it will not be able to run on it and be displayed as “incompatible” in the Play Store.
