[darrabam]

Hi there,

I'm noticing many crash reports logged in my App Center Issues for Android:

Bug

Version Number of Plugin: 3.0.0-beta
Device Tested On: Galaxy S8+, OnePlus 6 , Device, Y9 Prime 2019, and others
XF: 4.8.0.1560

Steps to reproduce the Behavior

I show the dialog by calling the request review
await Plugin.StoreReview.CrossStoreReview.Current.RequestReview(false);

Note that the application language is Arabic.

I don't have a physical device in order try to reproduce it, but I wonder if you could get a hint from the log on what could be the issue.

Thanks,

@darrabam Whats the Android version on those devices?
Android 5.0 or above?

The error says Java.Lang.IncompatibleClassChangeError: no non-static method "Lcom/google/android/play/core/review/c;.requestReviewFlow()Lcom/google/android/play/core/tasks/Task;" so, it could just not be available

Also, do you have a proguard file in your project? Whats the build configuration for it?

[darrabam]

@saamerm
Android 7, 8, 9 &10

No, I don't use proguard for my project. These are my build settings:

[saamerm]

Are you sure that's the release project configuration? I don't believe you can publish an app with Shared Mono Runtime enabled

[darrabam]

@saamerm sorry, you are right, this is the one:

[saamerm]

If you use proguard or r8, you need to have a proguard file for now so that the shrinker you are using to reduce the size of the APK file doesn't delete those classes.

Please follow the instructions in the readme to add a proguard file and publish a build with that.

I highly recommend that you test the In-App Review using "Android Internal App Sharing" before you publish

@darrabam ^

[darrabam]

@saamerm thanks for the hint, I'll try that.

[saamerm]

Any success @darrabam

[darrabam]

@saamerm yep, it worked! at least I got the rating dialog and managed to submit a review without a crash :)
Thank you very much

[saamerm]

@darrabam you mean without a crash?
