Build issues with new AndroidX namespace and D8

[vrendina]

When migrating to AndroidX and D8 I was not able to build because of the following error:

Task :app:transformDexArchiveWithExternalLibsDexMergerForDebug FAILED
AGPBI: {"kind":"error","text":"Program type already present: android.support.v4.app.INotificationSideChannel","sources":[{}],"tool":"D8"}

I was able to get the build to work again by excluding the support library group from my build.gradle file:

debugImplementation 'com.squareup.leakcanary:leakcanary-android:1.6.1' exclude group: 'com.android.support'

It looks like there is a support library dependency that is causing this problem.

leakcanary/leakcanary-android/build.gradle

Lines 5 to 11 in 700f64e

	// We don't need the latest version of the support library (there are no bugs that impact what
	// LeakCanary relies on), we're sticking a bit older because most apps will be using a more
	// recent version and they'll automatically resolve to higher version without having to
	// necessarily resort to a resolution strategy. This is also the version we use in
	// leakcanary-support-fragment.
	//noinspection GradleDependency
	implementation 'com.android.support:support-core-utils:26.0.0'

What would be the best approach?

You need to specify android.enableJetifier=true and android.useAndroidX=true in your gradle.properties which will automatically rewrite dependencies to use AndroidX.

Hi Jake thank you for the response. Both are set to true, but I am still seeing this problem when building.

android.enableJetifier=true
android.useAndroidX=true

When you run the dependencies task you should see the android.support.* transitive dependencies replaced with androidx.*. Do you?

This this the output for the debug build variant:

+--- com.squareup.leakcanary:leakcanary-android:1.6.1
| +--- com.squareup.leakcanary:leakcanary-analyzer:1.6.1
| | +--- com.squareup.leakcanary:leakcanary-watcher:1.6.1
| | --- com.squareup.haha:haha:2.0.4
| | --- org.jetbrains.trove4j:trove4j:20160824

| +--- com.android.support:support-annotations:26.0.0
| --- com.android.support:support-compat:26.0.0

Sounds like this is a gradle/jetifier issue. Thanks for pointing me in the right direction.

In case anyone sees this in the future the problem was with my Android Gradle plugin version. I was using 3.1.0 and needed to be using at least 3.2.0-alpha14 according to the docs. Now when I run the dependencies task I can see that all transitive dependencies of Leak Canary have been converted to the new androidx.* namespace.

If you depend on a library that references the older Support Library, Android Studio will update that library to reference androidx instead via dependency translation. Dependency translation is automatically applied by the Android Gradle Plugin 3.2.0-alpha14, which rewrites bytecode and resources of JAR and AAR dependencies (and transitive dependencies) to reference the new androidx-packaged classes and artifacts. We will also provide a standalone translation tool as a JAR.
