Can you explain why you have used coroutines-core along with coroutines android? In the documentation for android for coroutines only a single library implementation is used and that is the android implementation.

How to store custom object arraylist in room database, can you please add one video on it

[@CheezyCode]

just convert that into json and store it in DB

[@suhebrafique7341]

@@CheezyCode ok, thank you for the reply. Also i want to know can we store a complete arraylist at a time in room?

[@CheezyCode]

Yes.. 2 options- - Save method mei list of object accept karlo - arraylist as a unit store karana hai toh as a string save karlo by converting it into json

[@CheezyCode]

@Insert suspend fun addNote(notes: List) For instance - this method will store the list of notes in the db in one go

[@yunhi1853]

sir new errror pls suggest solution > 'compileDebugJavaWithJavac' task (current target is 1.8) and 'kaptGenerateStubsDebugKotlin' task (current target is 17) jvm target compatibility should be set to the same Java version.

[@nimeshluhana4796]

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]

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

Can we store the pdf document in room database?

[@CheezyCode]

We can store but what's the need. Keep the file as is and store it's name

[@mohammadtaqi4051]

Why did you pass "applicationContext"... What if we pass only "this"... Does this have any effect? (I know applicationContext ties with application lifecycle and"this" ties with activity lifecycle) if i am not wrong

[@CheezyCode]

Activity rotated activity died. Storing activity context holds the object, so memory leak
