#5 Android Room Tutorial - Using Coroutines

#AndroidRoomTutorial

In the last video we used AsyncTask to save our data into the database. And this process is a bit lengthy, so to minimize this effort we will implement Coroutines instead of AsyncTask in this video.

If you think this course is going to help you then please help me back by sharing this video to all your friends learning android application development.

And don't forget to follow us on

@1:59 to 2:59 code for gradle is as below

[wardengrant]

For any confusion at 4:22 he implemented interface CoroutineScope. You can only extend one class, but implement many interfaces.

It showing the lots error while using coroutines gradle build failed Not sure how to handle a insert method type..

[أحمديونس-جض]

sir when you create BaseFragment you use main job in addNoteFragment you use insert in main thread i think it's not better if you add the function to make insert operation inside launch it is become better

Hello sir, how to apply this inside an adapter?
I have a list in recyclerview and upon clicking an item popmenu appears for saving. Upon clicking save app crashes.
All are done but I didn't get any idea on how to fire coroutine inside adapter.

I am working on other project and i have a question that, can I use BaseActivity instead of BaseFragment with abstract class BaseActivity:AppCompactActivity(), CoroutineScope{} ?

[sawankumar]

async task is showing deprecated in AddNoteFragment

[karanveer]

Why didn't you use thread instead of asynctask?

[pembatamang]

hey I wrote a @transaction for deleting and adding a user that contains a delete query and an insert function, there seems to be some problem they work properly if I call it from my fragment but it returns an error when used as a transasction
sometimes a stackoverflow error sometimes a readonly error

[nikhilbhatnagar]

on inheriting the base class, the home fragment and the add note fragment is throwing an error saying that these classes aren't abstract hence the base fragment can't be implemented!! help please

[raghavaggarwal]

Hi Belal can we follow this approach:
GlobalScope.launch {
saveNote(note)
}
suspend fun saveNote(note: Note){



Toast.makeText(activity, "Saved", Toast.LENGTH_SHORT).show()
}


}
after declaring functions Notes.Dao as suspend
