Android apps are software applications 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 features on the device. Installing a variety of apps on an Android device could affect the battery’s performance and life.
Making Android apps requires a thorough understanding of the Android platform, including its design principles and frameworks. It also requires implementing an appropriate app architecture that divides UI and OS-related code into parts which share responsibilities. The system is able to activate these components asynchronously by using the broadcast mechanism, which is activated by intents.
Kotlin is gaining popularity as a language that is used for Android development. Both are supported by Android SDK. A large community of developers is available online to help newcomers to the language understand and fix issues.
The Android OS itself is divided into several layers, with the app layer consisting of the default apps that are included with the operating system, along with the specialized apps that are bundled with a specific device like the music player or phone dialer. 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 yet another factor which prevents some apps from working. If an app was released to the US market, but it’s not compatible with your European device, it will not work on it, and will be marked as “incompatible” in the Play Store.
