Async-storage: D8: Program type already present: com.reactnativecommunity.asyncstorage.AsyncLocalStorageUtil

[mattveraldi]

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

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!

If i unlink i get error that async storage is not linked

[focalsolution]

I still get the same error even after I ran

1. react-native unlink @react-native-community/async-storage
2. Ensure no async-storage references in settings.gradle
3. Ensure no async-storage references in app/build.gradle

Environment
"react-native": "0.62.2"
"@react-native-community/async-storage": "^1.11.0"

@focalsolution You should not have AsyncStorage entries (or any other auto-linkable libraries) in gradle.settings/build.gradle. Remove those and retry

[focalsolution]

@Krizzu Can you guide me how to know if any auto-link libraries in node_modules contain this AsyncStorage?

[focalsolution]

@Krizzu I figured it out and solved by excluding AsyncStorage from jitsi library.
Thanks a lot for your reply that can shed me some light.

I add these lines in the app/build.gradle

+     implementation (project(':react-native-jitsi-meet')) {
+         exclude group: 'com.facebook.react', module:'react-native-community-async-storage'
+     }

Uninstall async Storage it would work fine!
