This question- started answering and realised it is is actually a dupe and marked it. OPs clarification not withstanding. Knowledgeable folks here can clarify ?

@beeshyams What are you saying it's a duplicate of?

@beeshyams Did you mean this question? - android.stackexchange.com/questions/148994/…

oh, I see

I dunno: this later question is quite specifically asking for an API, while the earlier guy wants an API but is asking for a way to do it from the user's point of view.

I'm tempted to close as OT instead.

there, done

That does it but essentially I felt it was dupe in so far as playing audio while on call but don't have enough understanding

@beeshyams I think you're right about that. Playing music instead of vs as well as the mic input is not a significant difference.

Thanks @DanHulme

@bmdixon you are right didn't clarify well.. Thanks

@DanHulme: Very amused at this

I freaked out a little at my desk reading that, and everyone came over to gawp

Li-ion batteries really are just tiny firebombs

:o wow...

That's pretty dangerous... why would they think that would be a good idea?!

if people realised how dangerous those batteries are, they wouldn't use them at all

@bmdixon- beats me- i have heard of people put heating up laptops in fridge for a while (that is equally bad- think of condensation that would happen when taken out ) but this takes the cake (couldn't resist that being an oven)

@DanHulme- lot of safety built in these days

@DanHulme: As a mod can you trash the answer? If downvoting helps- would gladly do

Downvoted

@beeshyams I don't feel that that is a good thing to do, because it is an answer to the question. We don't delete answers for being wrong, even if they're dangerous.
