Using ~/Android/Sdk/platforms/android-34/android.jar or ~/Android/Sdk/platforms/android-VanillaIceCream/android.jar
sg...@google.com
Question to reporter: Which compileSdk is used in the project?
pu...@gmail.com
Thank you for looking into this. I'm using compileSdk 34. I had no issue with Koala 2024.1.2 Canary 5.
I could verify that this issue happens in any project that has desugaring enabled:
android.compileOptions.coreLibraryDesugaringEnabled=true
dependencies {
coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs_nio:2.0.4'
...
}
For example, use the AS (Canary 6) "Basic Views Activity" template, modify its build.gradle with lines above.
I have no idea why this function java.util.stream.DoubleStream java.util.stream.DoubleStream.iterate(double, java.util.function.DoublePredicate, java.util.function.DoubleUnaryOperator) is appearing, since it was introduced in VanillaIcecream and my app does not compile against it. Could it be an AGP / Lint issue (making use of R8) doing something with VanillaIcecream that it should not ?
sg...@google.com
Thank you for reporting back.
This looks like it is caused by the API database embedded in D8/R8. It was updated to contain the Android V API's in
pu...@gmail.com
Is there a version of R8 that I can manually revert to until this is fixed ?
Since AS Canary 6 is not really usable at the moment with desugaring which I believe most apps will have enabled, maybe it would be a good idea to ping the right people to revert to Canary 5.
ky...@gmail.com
We are getting similar errors with compileSdk 34.

FWIW we see it on one flavor that has minSdk 26 but not the other with minSdk 23.
And this happens with AGP 8.6.0-alpha06 + R8 8.6.4-dev but not with AGP 8.6.0-alpha05 + R8 8.6.6-dev
pu...@gmail.com
I any case, downgrading R8 does not work (tried various 8.6.x and 8.5.x versions).
pu...@gmail.com
Using the stable version of AGP (8.5.0) do work as work-around for Gradle Sync to complete in AS Canary 6.

Update DesugaredMethodList to work with old library
- Essentially missing methods in the library matter for html
doc generation more than for the lint, since no access flags
are required in the lint

8.5.28 and 8.6.12-dev should have fixes for this. We can keep this open until someone verifies
pu...@gmail.com
I confirm that both R8 8.6.12-dev and 8.5.28 work fine in conjunction with AGP 8.6.0-alpha07. Again, thanks for the fix !

er...@gmail.com
I can also confirm 8.6.12-dev fixed the issue for me. Thank you.
Will it be part of the release notes, whether it's in 8.6.0-alpha09 or another upcoming canary release?
pu...@gmail.com
This issue is fixed in AS Ladybug 2024.1.3 Canary 1, as it uses R8 8.7.1-dev (Interestingly this fix is not mentioned in the issue fixed list).
So if you had forced R8 8.6.12-dev in your settings.gradle, you can remove it now.

Description
I just upgraded from Koala 2024.1.2 Canary 5 to Canary 6 (which was just released), which upgraded AGP to
8.6.0-alpha06and R8 to8.6.6-dev.Since then, a Gradle sync of my project fails with in
java.lang.Error: Unexpected backport missing from Android U: java.util.stream.DoubleStream java.util.stream.DoubleStream.iterate(double, java.util.function.DoublePredicate, java.util.function.DoubleUnaryOperator).Here's the full gradle trace below.
Note that a
gradle assembleReleaseon the command line fails the same when it reaches thelintVitalAnalyzeReleasetask.I tried to configure the build to use the latest R8 release at this time (8.6.8-dev), but the error is the same.
If you need more info, let me know.
