Hey Good Explanation You have mentioned that the getContact function will be called in the background thread. Now, can this also be made a suspend function, so that we can use the advantages of a coroutine rather than running this on a thread only?

@nehasahoo2638 2 жыл бұрын

We can do that, but since we made its return type a livedata(which anyway runs on background thread) the suspend keyword is skipped for that function
