R8 warnings

[RobbWatershed]

Hi Sergey,

First of all, thanks a lot for making this library - it has helped me a lot!

I've been having a lot of warnings coming from R8. Could you investigate and tell me if I need to add a specific setting to avoid issues?

Using Android Studio Giraffe | 2022.3.1 Patch 1 and Gradle 8.1.0 here 😄

Thanks in advance~

Hi.
Such a log appears because the library uses some device-specific and/or Gray-listed classes, so R8 during obfuscation can't create a references tree properly.
It doesn't have any effect on the final code execution, just warns about unexpected cases.?
It seems like I need to do some fine-tuning in Proguard rules. Thank you for reporting

[RobbWatershed]

Yup, the library works as expected so far, though I don't have all the devices you have to test vendor edge cases.

It seems like I need to do some fine-tuning in Proguard rules.

Thanks!

You already can try the new version 2.2.4 for me the issue with Missing class... is gone.
Remains R8 warnings, that's relate class file version - some old JAR libraries from Samsung/Meizu contains classes, compiled with ClassVersion=50, when now ClassVersion=51 required.
I'm working under this fix too

[RobbWatershed]

Unfortunately, I can't test it right now as you've included window:1.2.0-beta01, which needs API34. However, my app hasn't made the jump yet 😅

[sergeykomlach]

@RobbWatershed so I downgrade the window version, now should be OK.
Also added a new section to README
Most of the warnings were removed, remains only a few, related to Samsung's libraries and older Class File versions (50 instead of modern 51).
Honestly, do not see any way how to remove it

[RobbWatershed]

Thanks! I confirm missing classes are not among warnings anymore 👌

However, I'm still getting ~40 lines of

AGPBI: {"kind":"warning","text":"Expected stack map table for method with non-linear control flow.

As it says "In later version of R8, the method may be assumed not reachable", shouldn't I completely exclude your library to the scope of R8 to avoid future issues?

[sergeykomlach]

As I said earlier, some warnings from Samsung Pass SDK remain - I didn't find a way to suppress or hide these warnings
They don't have an effect on libraries or applications for now, but I'll continue watching, maybe in future just update the minimal SDK level in the library and remove obsolete SDKs like Samsung Pass or Meizu SDK
