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 TVs. They’re extremely efficient in using the camera, touchscreen, and GPS features of the device. The addition of numerous apps to an Android device can affect the battery’s life and performance.
Understanding the Android platform and its design principles is crucial for the development of Android apps. It also requires an appropriate app architecture, which separates UI- and OS-related codes into components that share responsibility. These components can be activated in asynchronous fashion by the system via a broadcast mechanism that is triggered by the intents.
Kotlin is gaining popularity as a language for Android development. Both languages are supported by the Android SDK. A large community of developers is available online to help newcomers to the language and resolve issues.
The Android OS is divided into layers. The application layer comprises the standard apps that are included with the OS, in addition to any proprietary apps that are integrated with specific devices such as a music player or phone dialer. The Android app layer also includes custom firmware, like CyanogenMod or OMFGB. These can be installed to modify the functionality of specific devices.
Compatibility is another aspect that prevents certain apps from functioning. If an app is created specifically for the US but is not compatible with your European device it will not function and will be displayed in the Play Store as “incompatible”.
