I´m pretty sure the provided files for exoplayer doesn´t need to be desugared.
Why are you doing this?

BTW: We are in the B4J Forum here. Exoplayer is an Android Library, or not?

ExoPlayer is an application level media player for Android.

i am trying to use the latest version of exoplayer aar thats why i have to desugar the new aar and adjust the exoplayer with the new exoplayer function and remove the deprecated old version usage, then recompile the library

It is no longer needed to desugar libraries. Make sure to use latest version of B4A.

It is no longer needed to desugar libraries.

Where can I get more info on why this is no longer needed, or is it not needed for only certain types of libs?

 

[DonManfred]

why this is no longer needed

probably because of the new toolchains in the newest SDK.
Desugaring was needed before the new tools were available.

Excellent to know - thank you Don.

So does that mean that the newer SDK will allow the latest version of B4A to work with *any* library that worked with B4A 9.x?

I can not answer this. It is far above my knowledge about the toolchain.
I can´t see any reason why a library will not work.

Yes.
