Android apps are pieces of software that run the Android operating system. They can be installed on Android tablets, TVs and phones. They’re very good at utilizing the touchscreen, camera and GPS functions of the device. The installation of many apps on an Android device can affect the battery’s performance and life.
Understanding the Android platform and its design principles is vital for the development of Android applications. It also requires a well-designed app architecture that separates UI- and OS-related codes into components with shared responsibility. These components can be activated at a time that is synchronized by the system, using an event-driven broadcast mechanism, which is activated by intentions.
Java is the preferred language for Android development, however Kotlin has gained a lot of attention in recent years. Both languages are supported by the Android SDK. Online, there is an extensive group of developers who can assist newcomers to understand the language and resolve any issues.
The Android OS is divided into layers. The application layer comprises the standard apps that come with the OS, as well as any apps that are proprietary and integrated with specific devices for example, phones with a music player and dialer. The Android app layer includes custom firmwares, like CyanogenMod or OMFGB. These can be installed to modify the functionality of certain devices.
Another reason that stops certain apps from working is compatibility. If an app has been pushed out to the US market, but isn’t compatible with your European device, it won’t be able to Android devices run on it and be listed as “incompatible” in the Play Store.
