Developing Android Apps

Android apps are software programs that run on the Android OS. They can be installed on Android tablets, TVs, and phones. They’re extremely efficient in using the camera, touchscreen and GPS functions of the device. Installing a variety of apps on an Android device can affect the battery’s life and performance.

In order to develop Android apps requires a thorough understanding of the Android platform as well as its design principles and frameworks. It also involves the implementation of an appropriate architecture for apps that separates UI and OS-related code into components which share responsibilities. These components can be activated in asynchronous fashion by the system via a broadcast mechanism triggered by intentions.

Java is the preferred language Android apps for Android development, although Kotlin has gained popularity in recent years. Both are supported by the Android SDK. A large developer community 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 app layer consisting of the default apps that ship with the operating system, as well as proprietary apps that come with a specific 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 enhance the capabilities of specific devices.

Another factor that prevents some apps from functioning is compatibility. If an app was released for the US market, but it’s not compatible with your European device, it will not be able to run on it and appear as “incompatible” in the Play Store.
