Developing Android Apps

Android apps are software programs that run on the Android OS. They can be installed on Android tablets, phones and televisions. They are very good at using the camera, touchscreen and GPS features on the device. Having lots of apps installed on an Android phone is, however, a problem that can impact the life of batteries and performance.

Understanding the Android platform and its design principles is vital in the creation of Android apps. It also requires a well-designed app architecture that separates UIand OS-related code into components that have shared the same responsibilities. The system is able to activate these components asynchronously through the broadcast mechanism, which is activated by the intents.

Kotlin is gaining popularity as a language that is used for Android development. Both are supported by Android SDK. Online, there’s an extensive group of developers who can help newcomers learn the language and help with any problems.

The Android OS itself is divided into multiple layers, with the application layer consisting of the default apps that come with the operating system, along with the specialized apps bundled with a particular device like the phone dialer or music player. The Android application layer comes with custom firmware, such as CyanogenMod or OMFGB. These can be installed to modify the functionality of specific devices.

Compatibility is another factor that stops certain apps from functioning. If an app was made available for the US market but is not compatible with your European device, it will not function on it and will be marked as “incompatible” in the Play Store.
