Why is my Gradle Failing on my Unity Android Build?

Question

I used to use 'Internal' option to build my Android Version but in Unity 2019 there is no option.

When trying to build my Android version I get the following errors:

D8: Program type already present: android.support.annotation.FractionRes UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':transformClassesAndResourcesWithR8ForRelease'. com.android.tools.r8.CompilationFailedException: Compilation failed to complete * Try: Run with --stacktrace option to get the stack trace.

Answer 1

Library com.android.support:support-annotations:26.1.0 should only exist once in the package:

implementation ("com.android.support:support-v4:26.1.0") {
    exclude group: "com.android.support", module: "support-annotations"
}

Answer 2

It looks like you're including the symbol android.support.annotation.FractionRes multiple times (see this).

My first guess is that you used to explode the JARs and now they're just included in your gradle file. You might want to clear out Assets/Plugins/Android (especially if it's filled with jar files) and force run the play services resolver afterwards. See this.

My second guess is that this has to do with the support library to androidx migration Firebase underwent in June. In this case, there are a few things you can do to resolve the issue.

First, make sure that you have the latest (6.5.0 as of right now) Unity SDK. Back in July, updates were made that fix these sorts of issues specifically.

Next, look at your play services resolver settings and make sure Patch mainTemplate.gradle and Use Jetifier are selected. Especially if you do have a mainTemplate.gradle file, this will help resolve some issues.

I've written up some information about the Play Services Resolver here, which I also linked above.

I hope something here helps!

• What went wrong: Execution failed for task ':transformClassesAndResourcesWithR8ForRelease'.FAILED

if you using below lines in progaurd-project file, then comment them and Generate release build again.
