What language is the Android program written in?

Android uses Java as the programming language, which makes the interface and functions change endlessly. Among them, Activity is equivalent to J2ME's MIDlet, an Activity class is responsible for creating a window, an Activity is in foreground mode, and the program running in the background is called Service.

These two programs are connected by ServiceConnection and AIDL, so that multiple programs can be run at the same time. If all the pictures of the running activity are replaced by other activities, the activity will be stopped or even terminated by the system.
