Developing Android Apps

Android apps are software programs that run on the Android OS. They can be installed on Android tablets, phones, and TVs. They’re very good at utilizing the camera, touchscreen, and GPS features of the device. A lot of apps installed on an Android phone is, however, a problem that can impact the life of other batteries and performance.

Understanding the Android platform and its design principles is crucial for the development of Android apps. It also requires creating an appropriate app architecture that separates UI and OS-related code into pieces which share responsibilities. These components can be activated through asynchronous communication with the system by a broadcast mechanism triggered by the intents.

Kotlin is becoming more popular as a language used in Android development. Both languages 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 come with the operating system and also the proprietary apps that come with a specific device like the phone dialer or music player. The Android app layer also includes customized firmware, such as CyanogenMod or OMFGB. They can be installed to customize the functionality of certain devices.

Compatibility is another factor that stops certain apps from functioning. If an app is designed specifically for the US but isn’t compatible with your European device it will not run and will appear in the Play Store as “incompatible”.
