How does Android manage memory?

I studied this topic because I wanted to know more. So I found out the following:

Android OS attaches great importance to our application, based on the following factors:

  • Foreground Process - onResume()when we interact with the user interface of the application. (Highest value)
  • The visible process is onPause()when some kind of dialog box goes beyond the application that we are currently using.
  • Service process . There is no interaction with the user interface, but there is a service that works best, for example, an MP3 player.
  • Background process . There is no interaction with the user interface, but there is a thread trying to load the image.
  • The empty process . In this process no active components ( Activity, Service, Content Provideror BroadCast Receiver). (The lowest value will be the first to be deleted from memory).

I should give a seminar on this topic, but, of course, I need to give an example for each of the above 5 cases.

I find it difficult to find an example of a Background process .

So, for an application that should be classified as a background process for the Android OS, then there should be no user interaction, and the thread should work.

The fact is that I cannot come up with a convincing example for a background process.

Can someone help me?
