Developing Android Apps

Android apps are pieces of software that run on the Android operating system. They can be downloaded on Android devices like tablets, TVs and phones. They are extremely adept in making use of the touchscreen, camera and GPS features on the device. The addition of numerous apps to an Android device can impact the battery’s performance and life.

The process of creating Android apps requires a deep understanding of the Android platform as well as its design principles and frameworks. It also requires a solid app architecture, which separates UI- and OS-related codes into components that have shared responsibility. The system can trigger these components asynchronously through an asynchronous broadcast mechanism that is activated by intentions.

Java is the preferred language for Android development, although Kotlin has gained a lot of attention in recent years. Both languages are supported by the Android SDK. Online, there’s a large group of developers who can assist newcomers to understand the language and resolve any problems.

The Android OS itself is divided into several layers, with the application layer comprising the standard apps that ship with the operating system, as well as the custom applications that are included with a particular device, like the music player or phone dialer. The Android application layer comes with custom firmware, like CyanogenMod or OMFGB. These can be installed to enhance the capabilities of specific devices.

Compatibility is a different factor that stops certain apps from working. If an app was released for the US market, but it’s not compatible with your European device, it won’t work on it, and will be displayed as “incompatible” in the Play Store.
