D8: Program type already present: com.reactnativecommunity.asyncstorage.AsyncLocalStorageUtil

Current behavior

gradlew buildRelease don’t build my app because of an issue with async-storage.

Expected behavior

It should build without errors.

Repro steps

I added this library on my project.

Environment

• Async Storage version: 1.8.1
• React-Native version: 0.61.5
• Platform tested: Android
• Logs/Error that are relevant: `> Task :app:transformClassesAndResourcesWithR8ForRelease FAILED R8 is the new Android code shrinker. If you experience any issues, please file a bug at https://issuetracker.google.com, using ‘Shrinker (R8)’ as component name.

I ran into the similar issue, tried all steps, didn’t work. I checked my package.json file and I figured out that i had 2 versions of react-native-async-storage, the community one and the oldest one. Just delete the old one, re-install with yarn on NPM, and it should work.

Is AsyncStorage linked manually? Have you tried to clean and rebuild? Or try to disable R8 to see if it can build without it?

@Krizzu thank you for your reply. I solved it. At the time I installed this package at first I linked it manually, then, I unlinked it via react-native unlink @react-native-community/async-storage. But I found out there were still some references in settings.gradle and build.gradle, I removed them and now it works fine!
