QUESTION How can i achieve Asynchronous Behavior. As it is deprecate Now. Is there alternative in android development to Download image in background.

I read the solution on stackoverflow of using thread for background task but it crash the App when i press a button to Download the image.

Answer 1

For running background tasks you have

• MutliThreading
• Rx Java
• Coroutines (Kotlin)

among the above three coroutines is preferred as it is easy to learn and more efficient
