Build fails on 3.1.1 and above

[sander121]

When building for android with 3.1.0 everything works fine.
When building with 3.1.1and above I get the error:

FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring project ':flutter_reactive_ble'.

class com.android.build.gradle.internal.api.TestVariantImpl_Decorated cannot be cast to class com.android.build.gradle.internal.core.InternalBaseVariant (com.android.build.gradle.internal.api.TestVariantImpl_Decorated is in unnamed module of loader org.gradle.internal.classloader.VisitableURLClassLoader @5db3
98dd; com.android.build.gradle.internal.core.InternalBaseVariant is in unnamed module of loader org.gradle.internal.classloader.VisitableURLClassLoader @69421090)

I do not understand enough of gradle to see the problem. Does someone else have this as well and maybe also found a solution? Thank you.

We needed to update to the latest stable gradle version + wrapper + android dependencies.

If you update tools to classpath 'com.android.tools.build:gradle:4.2.1' and the wrapper version to 6.8.1. The app should build

Thank you for your quick help. This indeed makes the error messages I got before disappear. Unfortunately it causes many more problems, all releated to incompatible kotlin and gradle versions. I will stick to 3.1.0 for now.

I updated my build tools and wrapper version to the ones listed to resolve this issue.

I now receive the following error. Curious if someone also ran into this problem after following the steps...

* What went wrong:
Execution failed for task ':app:processReleaseResources'.
> A failure occurred while executing com.android.build.gradle.internal.res.LinkApplicationAndroidResourcesTask$TaskAction
   > Android resource linking failed

I too have this error.

@safield @Edu09campos Please checkout the answer on this other (solved) issue: #410 (comment)

That info has been added to the readme as well.

Please see the note I just made at #410 regarding a comment made by @YellowShark about setting the Android SDK to 31.
