Developing Android Apps

Android apps are pieces of software that run on the Android operating system. They can be installed on Android devices like tablets, TVs and phones. They excel at making use of the touchscreen, camera and GPS features on the device. A lot of apps installed on an Android phone is, however, a problem that can impact the life of batteries and performance.

In order to develop Android apps requires a deep understanding of the Android platform as well as its design principles and frameworks. It also means developing an appropriate app architecture that separates UI and OS-related code into separate components that share responsibilities. The system can trigger these components in asynchronous fashion using the broadcast mechanism, which is activated by desires.

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 online to help those who are new to the language and fix issues.

The Android OS is divided into layers. The application layer includes the standard apps that come with the OS, and any custom apps that come bundled with specific devices, for example, a music player or a phone dialer. The Android application layer comes with custom firmware, such as CyanogenMod or OMFGB. They can be installed to alter the functions of certain devices.

Another reason that blocks certain apps from working is compatibility. If an app has been released for the US market but isn't compatible with your European device, it will not work on it and will be displayed as "incompatible" in the Play Store.
