Developing Android Apps

Android apps are software programs that run on the Android OS. They can be installed on Android tablets, TVs and phones. They are extremely adept at using the touchscreen, camera and GPS capabilities of the device. The presence of a lot of apps on an Android phone can, however, affect battery life and performance.

Understanding the Android platform and its design principles is essential to develop Android apps. It also requires a well-designed app architecture, which separates UIand OS-related code into components that share the same responsibilities. These components can be activated at a time that is synchronized by the system, using the broadcast mechanism that is activated by intents.

Java is the preferred language for Android development, although Kotlin has gained a lot of attention in recent years. Both are supported by Android SDK. On the web, there’s an enormous community of developers that can assist newcomers to understand the language and resolve any issues.

The Android OS is divided into layers. The app layer includes the standard apps that come with the OS, in addition to any custom internet apps that come integrated with specific devices like phones with a music player and dialer. The Android application layer comes with customized firmware, such as CyanogenMod or OMFGB. They can be installed to customize the functionality of specific devices.

Another reason that hinders certain apps from working is compatibility. If an app was designed for the US but isn’t compatible with your European device, it won’t run and will appear in the Play Store as “incompatible”.
