React-native-firebase: 🔥 Error while generating the main dex list

[lzwebc]

Issue

I'm trying to move my app to react-native-firebase-starter so I initialized app with react-native-firebase-starter and installed packages with yarn add.
When I try to run react-native run-android I get this error:

Execution failed for task ':app:transformClassesWithMultidexlistForDebug'.
> com.android.build.api.transform.TransformException: Error while generating the main dex list.

I've tried everything I could find and nothing helps.

I got the issue fixed by running react-native unlink react-native-firebase to unlink firebase. I guess there's an issue when linking it for some reason.

Anyone plz help us :confused:

react-native unlink react-native-firebase

this works! thank you

Please tell me how to solve this issue.

[mikehardy]

I don't know, I can't reproduce it - see automated react-native-firebase example build here to make sure it works in your environment: https://github.com/mikehardy/rnfbdemo - you can fork that repo and add the database dependency if you like, and if you can demonstrate the failure we can try to fix it. But this is a stale issue so you might like to open a new one with full information filled in the template

[mikehardy]

Okay, I was working on react-native-firebase-starter today to upgrade it so it matches the current v5.5.4 release of react-native-firebase and I could finally reproduce this

It's a gradle cache issue, and if it happened for others the way it happened for me, you maybe tried to yarn android or somehow run the android gradle build before you did the yarn rename. Gradle cached some of the outputs and you end up with some pretty bizarre object collisions as gradle tries to merge the old build and the new build together to package it.

For me, I did rm -rf android/.gradle to clear out the project cache and that worked
