An error on fetching messages

[mako-yolo]

Hi guys!

My release build is getting the next error: "Error fetching messages: java.lang.Class cannot be cast to java.lang.reflect.ParameterizedType" and I don't get any push notifications and in-app messages on Android. The debug build has no issues.

How can I fix it?

Thanks.

Hey @mako-yolo, are you using proguard/R8 in your production apps?

[mako-yolo]

No, I don't. We are checking without any kind of obfuscation on release builds.

[Shahroz16]

Can you please share your gradle file If possible? or any kind of sample for us to reproduce?

[mako-yolo]

I can't but there is nothing there related to obfuscation or shrinking.

• here are more logs

[mako-yolo]

[mako-yolo]

@Shahroz16 JFYI: R8 obfuscation is enabled by default for Flutter projects Please check here

[mako-yolo]

@Shahroz16

release { // If I add these 2 lines to build.gradle then everything is fine, but it's not a solution for us. They weren't there before shrinkResources false minifyEnabled false ... }

[Shahroz16]

@mako-yolo when you set minifyEnabled to true it turns on R8 with full mode in you are on Gradle 8. We have noted it down and will check what is being obfuscated.

Meanwhile, can you downgrade gradle version?

[mako-yolo]

@Shahroz16 Thank you!

I have tried to downgrade to 7.6.1 and got a lot of errors. I'll have to try to roll back too many things in the project and I doubt that it's possible. I just don't have time for this.

[Shahroz16]

@mako-yolo can you try adding

android.enableR8.fullMode=false

in gradle.properties ?

[mako-yolo]

I got this after I had disabled the full mode.

Caused by: [CIRCULAR REFERENCE: com.android.tools.r8.internal.h: Missing class org.slf4j.impl.StaticMDCBinder (referenced from: org.slf4j.spi.MDCAdapter org.slf4j.MDC.bwCompatibleGetMDCAdapterFromBinder())] 

this makes me think you would need to add this to your proguard file of the app and hopefully this would fix it

-dontwarn org.slf4j.impl.StaticLoggerBinder

Again, we are working on Gradle 8 support alongside the Proguarding changes needed for R8 full mode and hope to send it out soon, while I do understand that it is hard to downgrade, my recommendation would be until we provide support for proguarding I would suggest utilizing the previous Gradle version as you were using before.

We'll be waiting for the new library version.

@Shahroz16 Could you please tell me when approximately your team release the fix?

[Shahroz16]

@mako-yolo we are working on it in the current development cycle, so while I can't give any timelines but this is our top priority.

[Shahroz16]

@mako-yolo the new Flutter SDK release is out, which should resolve this issue for you. Please feel free to re-open the issue if you stumble on any thing else.

Note: We have not rolled down the Gradle 8 changes yet, this release just adds the proguard rules that are required for R8 strict mode.
