IssueTracker

Hello there!

Thank you for the heads up this has been already reported internally.

Hello,

The expected impact of this bug is considered low (it's a narrow edge case with no upvotes, and should be avoidable on the consumer side by trimming inputs). As a result, our engineering team has deprioritized the issue until there is evidence of further impact. I am going to mark this as Won't Fix to more accurately reflect this. Please re-open if the scope of the issue changes. Thanks!

Thank you for reporting an issue. Can I ask you to run with --info to see if there are any messages/warnings about missing classes. Also, would it be possible for you to share on of the modules privately? If so, you should be able to add the argument -Dcom.android.tools.r8.dumpinputtofile=/path/to/file as an argument to the gradle task, which will bundle up the code and library dependencies - along with the configuration.

After add the option '--info', there are the logs:

R8 is a new Android code shrinker. If you experience any issues, please file a bug at
https://issuetracker.google.com, using 'Shrinker (R8)' as component name. You can
disable R8 by updating gradle.properties with 'android.enableR8=false'.
Current version is: 1.6.67 (build 63035baeff4ab2f5079d99c54d86d9a4839c158c from go/r8bot (luci-r8-ci-xenial-7-83cg)).

It seems that the missing class is from the junit library. I guess it's very easy to reproduce with the configs in comment#2.

The missing class is due to the class java.lang.ClassValue is not present on Android (https://developer.android.com/reference/java/lang/package-summary).

How can we fix this issue? Is there any workaround?

Ideally, you should not add test-code to your main app. That should go into the tests only. The reason why we try to minify it in the end is because there is code that ends up keeping the test-code. Until working on a fix, because we should not crash, you can try to see if it is possible to move junit code to the tests.

The app only has test code in it. It's designed to provide the compatibility test for our apps on our devices. I just set "minifyEnabled" false for temp workaround.

OK, I think I understand your setup a bit better now, but please clarify if I am mistaken. I assume you are "bundling" the compatibility tests together with the app for running your tests and would like to run it as close to the final product as possible and therefore you have minifyEnabled=true. Thereby, disabling R8 completely by setting minifyEnabled=false is not that desirable.

Since the NPE happens during minification (sorry for the clash in naming here, we call minification the renaming part where we rename Foo.Bar.BazWithLongName to -> a.a.a), you can just disable that part by using the -dontobfuscate keep rule. That would allow you to still run R8 and test your app.

To solve your problem, it would be great to figure out exactly why this fails, so could I ask you to run with assertions enabled? That should point to what class we could not find the reservation state for. You can enable assertions by running the gradle task as follows:

JAVA_OPTS="-ea:com.android.tools.r8..." ./gradlew --stacktrace clean :app:assembleRelease

for linux and mac, or setting the environment variable on windows as follows:

set JAVA_OPTS="-ea:com.android.tools.r8..."

Hopefully, we will see an assertion error like "Could not find reservation state for ...". When we know what class/classes are causing issues, and how they are related to the missing classes, I should be able to make a local reproduction and fix the issue.

Yes, you understood well and -dontobfuscate works for my case.

It seems that the assertion was not triggered:

I filed a dupe (https://issuetracker.google.com/issues/150511124) and have tried enabling assertions as above too - I also didn't get any lines with 'Could not find reservation state...' unfortunately :(

Is there a way to check the assertions got enabled properly?

I was able to enable the assertions by adding the -ea:com.android.tools.r8... to our org.gradle.jvmargs setting in the project gradle.properties.

There was nothing about the reservation state. This is the assertion it hit:

Thank you all for chipping in and trying with assertions enabled. R8 will print "Running R8 version XXX with assertions enabled". If you do not see it, then R8 is not running with assertions. It can also be added (as gleach@ showed) to the gradle.properties jvm options.

Seems like we in the first find trace an assertion error earlier, but the problem reproduces on 4.0 beta 1 with the retraced stack trace:

I still didn't see the assertion.

If you run with --info as well, do you see the message that R8 is running with assertions enabled?

I've just tried add this flag to the end of our jvmargs too as follows:

org.gradle.jvmargs=-Xmx6g -XX:MaxMetaspaceSize=512m -Dkotlin.daemon.jvm.options=-Xmx6g,-XX:MaxMetaspaceSize=512m -ea:com.android.tools.r8...

Is that correct? I still don't see a log about assertions in the output. Is it meant to be ... at the end?

Still no assertions found.

emmag@, yes that should be correct. The ... in the end says "for all subpackages".

tuyongce@, can I ask you to try without --no-daemon

Also, if any of you do not mind sharing the compiled sources privately, you can run:

./gradlew <FAILING-R8-TASK> -Dcom.android.tools.r8.dumpinputtofile=/path/to/write/dump.zip

That will produce a dump with the compiled class files generated by javac/kotlinc, all libraries used, the proguard rules and allow us to directly observe the problem. You can then send the file privately to mkroghj@google.com

I have tried generating projects that include Junit and have missing classes, but it is sadly not that easy to reproduce because of the possible uses in the program.

I have sent through a dump zip via email.

I just noticed something whilst doing this - at first, I wasn't getting a dump.zip output. I realised it was because I still had the assertion flag in there. The exception has actually changed slightly - it's no longer an NPE but now an AssertionError:

emmag@, thank you for providing the dump. I have found the error and will work on creating a fix for it. Regarding the assertion error posted here, it is because you have a proguard rule as follows:

-keepclassmembers @<some_package_name_here>.JsonClass @kotlin.Metadata class * {
    synthetic <init>(...);
}

The syntax for class-specifications seem to not support multiple annotations.

mkroghj@, I've shared a dump (for both AGP 3.6.1 and 4.0.0beta1) via GDrive with you. As far as I can tell, we don't have any lines in the config that use multiple annotations, so for us it seems to be something different than #22.

Let me know if I can do anything else to help.

Thank you all for the dumps. I have a solution up for review that should solve the issue for all. Will post back here on how to obtain it when it lands.

I used an incorrect bug-tracking id for the review, which is why you have not seen it added here. Basically, the fix has landed in: https://r8-review.googlesource.com/49542

Would it be possible for any of you to try out the fix and try out version 1.6.82 by adding the following to your top-level build.gradle file:

buildscript {

repositories {
    maven {
        url 'https://storage.googleapis.com/r8-releases/raw'
    }
}

dependencies {
    classpath 'com.android.tools:r8:1.6.82'          // Must be before the Gradle Plugin for Android.
    classpath 'com.android.tools.build:gradle:X.Y.Z' // Your current AGP version.
 }

}

That should fix all issues you have seen so far. If not, please comment back here.

This now works for us! Thank you 🙌🏻

Thank you emmag@ for providing the dump and being responsive. The fix is rolling into Studio and will hopefully be in the next point-release. You should probably use 1.6.82 until the next release since the only difference between the version in AGP and 1.6.82 is that the latter has more bug-fixes in it.

R8 v1.6.82 fixed the issue. Thanks!

Thanks for trying to build with assertions enabled.

The retraced stack trace is:

This indicates that there is a class in your program that implements a (non-interface) class, or that an interface extends a (non-interface) class.

Would it be possible for you to share a reproduction project of this? If you prefer to share it privately you can send it to christofferqa@google.com or sgjesse@google.com.

When you build with compiler assertions enabled, then yes, that should lead to a build error. Does your debug build succeed without assertions errors if you build with compiler assertions enabled? I would expect the debug build to fail with the same assertion error, assuming you are also using R8 for your debug build.

If you build with R8 version 1.6.90 (without assertions enabled) the assertion error should now have a message that pinpoints which class in your program that implements a non-program class. You can build with 1.6.90 by making the following changes to build.gradle:

buildscript {
    repositories {
        maven {
            url 'https://storage.googleapis.com/r8-releases/raw'
        }
    }
    dependencies {
        classpath 'com.android.tools:r8:1.6.90'          // Must be before the Gradle Plugin for Android.
        classpath 'com.android.tools.build:gradle:X.Y.Z' // Your current AGP version.
     }
}

Thanks for the quick update. That sounds like a bug in com.google.android.gms. Which version of the library are you using?

adioos88@ I opened b/157643753 to track this issue. I will follow up with more information there after debugging the problem.

I got the exception too these days. I tried the configurations:

buildscript {
    repositories {
        maven {
            url 'https://storage.googleapis.com/r8-releases/raw'
        }
    }
    dependencies {
        classpath 'com.android.tools:r8:1.6.90'          // Must be before the Gradle Plugin for Android.
        classpath "com.android.tools.build:gradle:4.1.2"
        classpath 'org.greenrobot:greendao-gradle-plugin:3.3.0'
     }
}

But there still was the NullPointException. For more details, please check out the attachment. By the way, My quifft module implements the rt.jar, which is the Java library.

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:minifyReleaseWithR8'.

com.android.tools.r8.CompilationFailedException: Compilation failed to complete

gengshengjie13@ the stack trace above is from R8 2.1.86 (note the frame at Version.fakeStackEntry(Version_2.1.86.java:0)).

Can you try building with R8 2.1.101 to see if this resolves the NPE?

the NPE still exists after using the R8 2.1.101.

Caused by: java.lang.NullPointerException

In fact, I knew it was the quifft module that caused the NPE(I have tried to remove the module, then built the apk successfully) As for the quifft, please check out the attachment. Thanks!

Unfortunately it is not clear from the stack trace where the NPE comes from. Would it be possible for you to share a dump of the inputs to R8, including your app's JVM class files? You can generate such a dump by issuing the command ./gradlew assembleRelease --no-daemon -Dcom.android.tools.r8.dumpinputtodirectory=/path/to/dir (see also https://r8.googlesource.com/r8/+/refs/heads/main/doc/compilerdump.md).
