Developing Android Apps

Android apps are bits of software that run on the Android operating system. They can be installed on Android tablets, phones, and televisions. They are extremely adept in using the touchscreen, camera and GPS features on the device. The installation of many apps on an Android device can affect the battery’s life and performance.

In order to develop Android apps requires a deep understanding of the Android platform and its design principles and frameworks. It also requires a well-designed app architecture that separates UIand OS-related code into components with shared responsibility. The system is able to activate these components asynchronously by using broadcast mechanisms that are triggered by intents.

Java is the preferred language for Android development, although Kotlin has gained popularity in recent years. Both are supported by Android SDK. A large community of developers is available online to help those who are new to the language and troubleshoot problems.

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

Compatibility is yet another factor that hinders certain apps from functioning. If an app is created for the US but not compatible with your European device it will not function and will be displayed in the Play Store as “incompatible”.
