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 are extremely adept at using the camera, touchscreen, and GPS functions of the device. Having lots of apps installed on an Android phone is, however, a problem that can impact the battery’s life and performance.
Understanding the Android platform and its design principles is vital for the development of Android apps. It also requires creating an appropriate app architecture that is able to separate UI and OS-related code into pieces which share responsibilities. The system can activate these components asynchronously by using the broadcast mechanism, which is activated by intents.
Java is the preferred language for Android development, however Kotlin has gained popularity in recent years. Both languages are supported by Android SDK. A large community of developers is available online to help newcomers to the language understand and troubleshoot problems.
The Android OS is divided into layers. The application layer comprises the standard apps that come with the OS, as well as any other proprietary apps that are included with specific devices, for example, a music player or a phone dialer. The Android app layer also includes custom firmware, like CyanogenMod or OMFGB. These can be installed to enhance the capabilities of specific devices.
Compatibility is a different factor that stops certain apps from functioning. If an app has been made available to the US market but isn’t compatible with your European device, it won’t be able to run on it and be listed as “incompatible” in the Play Store.
