android: Gradle build error due to Android support lib 27.1.0 usage / Program type already present

CLI version: 4.2.1 Android runtime version: 4.2.0 minSdkVersion: 21 targetSdkVersion: 26

Not sure if this is a bug, but after upgrading to {N} 4.2 our release build for Android fails during Gradle’s :app:transformDexArchiveWithExternalLibsDexMergerForRelease task.

Error:

D8: Program type already present: android.support.design.widget.CoordinatorLayout$Behavior

FAILURE: Build failed with an exception.

What went wrong: Execution failed for task ‘:app:transformDexArchiveWithExternalLibsDexMergerForRelease’.

It turned out that the Android support lib version used in the generated platforms/android/app/build.gradle is causing this.

Workaround was to add this to the App_Resources/Android/app.gradle file

ext {
    supportVersion = "27.1.0"
}

then compilation works fine.

Just tried it and it worked on Android 4.3. Seems good!

@edusperoni I’ve found what’s causing the error. We are using getDeclaredMethods of the TextInputLayout class to get the list of available methods when searching the corresponding Java method of a JavaScript method call. So this call is causing the app to crash. You can reproduce the same behaviour in a native app by calling the following code:

Class<?> clazz = Class.forName("android.support.design.widget.TextInputLayout");
Method[] declaredMethods = clazz.getDeclaredMethods();

We’ve found a fix for this and I hope it will be part of our next release. Thanks for helping me finding the root cause!
