Developing Android Apps

Android apps are software applications that run on the Android OS. They can be downloaded on Android tablets, phones and TVs. They are excellent at making use of the touchscreen, camera and GPS features of the device. The addition of numerous apps to an Android device can affect battery life and performance.

Understanding the Android platform and its design principles is essential to developing Android apps. It also requires a well-designed app architecture, which can separate UIand OS-related code into components with shared the same responsibilities. These components can be activated asynchronously by the system using an event-driven broadcast mechanism, which is activated by the intents.

Java is the preferred language for Android development, though Kotlin has gained a lot of attention in recent years. Both are supported by Android SDK. A large developer community is available online to assist 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 are included with the OS, as well as any proprietary apps that are integrated with specific devices for example, the music player or phone dialer. The Android application layer also has custom firmware, such as CyanogenMod and OMFGB, which can be installed on specific devices to customize their functionality.

Another reason that stops certain apps from functioning is compatibility. If an app was pushed out to the US market, but it’s not compatible with your European device, it will not function on it and will be marked as «incompatible» in the Play Store.
