React-native-firebase: MultiDex needing in Android and having to remove build folder on every launch

[BrianIto]

Hello everybody, I was developing a project with the version 6.3.4.

Everytime when I run my Android project I have to remove my android/build to it finish the build, because if I don't I got a problem with google-services.json.

If anyone needs more details, I can pass it, no problem.

*Sorry, if it lack of details, I'm not an Issue Reporter, this is my first. (:

Have you encountered this problem?

> Task :app:transformClassesWithMultidexlistForDebug FAILED 
D8: Program type already present: io.invertase.firebase.BuildConfig

FAILURE: Build failed with an exception.

* What went wrong:
> Execution failed for task ':app:transformClassesWithMultidexlistForDebug'.
> com.android.build.api.transform.TransformException: Error while generating the main dex list:
  Error while merging dex archives:
  Program type already present: io.invertase.firebase.BuildConfig

I'm not able to run my application, even though I make all the changes to the native code to work with DEX

I created a gist with my build.gradle, mainApplication and Error 👇

@eugustavo I have a hunch this is a problem with Android Studio 4.0

People aren't following the template so I can't say definitively, but if you can still reproduce this with Android Studio 3.4 (current stable, not a beta version) and gradle plugin 3.6.1 (current stable) I will be surprised

cross link: #3254

If you run my example here, which should build current stable versions of everything, I believe it still works? https://github.com/mikehardy/rnfbdemo/blob/master/make-demo-v6.sh

@eugustavo I had this problem before, I just removed the build folder at android/app and it worked for me.

The main problem here, is that everytime I launch, I need to remove this same build folder because if I don't, it simply doesn't start.

If you have linked the package manually, then you have to disable auto-linking of specific package by creating a file react-native.config.js in base project folder like this:
module.exports = { dependencies: { '@react-native-firebase/app': { platforms: { android: null }, }, '@react-native-firebase/crashlytics': { platforms: { android: null }, }, }, }

The main problem here, is that everytime I launch, I need to remove this same build folder because if I don't, it simply doesn't start.

I found the problem in the application. It consisted that the same lib was being used 2 times in different versions.
I solved that and the application made the build, but now it always closes when it loads, I'm checking this error now. Hope this helps!

@eugustavo I don't have this in my package.json, but I'm really glad you found the problem in your project. Well, I'm digging a little to found the problem in my project to erase the build folder anytime I run react-native start

@BrianIto
Im also facing same issue
and since the very start im not using react-native-firebase
All im using is

Its very strange
It only comes since i did this change
multiDexEnabled true in defaultConfig section of build.gradle

But i need to do this to avoid some other dex error...

I've added this to the docs: https://rnfirebase.io/#android-enabling-multidex

[gotyet9]

@BrianIto Did you come across any workaround for this issue ?
For me even deleting build thing doesnt work.

It keeps on throwing the below error:

`

Execution failed for task ':app:transformClassesWithMultidexlistForDebug'.
com.android.build.api.transform.TransformException: Error while generating the main dex list:
Error while merging dex archives:
Program type already present: io.invertase.firebase.BuildConfig

Also since the very start i have been using

And no other firebase package ever.
That's why i'm more shocked looking at other's solution.
they ask to remove react-native-firebase but i dont have any...

hey @gotyet9 did you figure out the solution to this? Cheers

Well, finally I solved this problem by disable auto-linking.
First create a file name react-native.config.js in your root of project with the following content:

module.exports = {
  dependencies: {
    '@react-native-firebase/app': { platforms: { android: null } },
    '@react-native-firebase/messaging': { platforms: { android: null } },
//all the packages related to firebase
  },
};

After that, please link you package manually and update your project (pod, android libraries).
npx react-native run-android

I have tried all the solutions and only this worked for me. Hope this help!

I'm glad you found a solution, but disabling auto-linking is a drastic step, I would only do it as a last resort. There are thousands (a hundred thousand maybe?) users of react-native-firebase and this does not show up often, so I suspect the underlying cause is a local project misconfiguration somehow, that still bears investigation / comparison (perhaps with https://github.com/mikehardy/rnfbdemo/blob/master/make-demo-v6.sh ?) so we can reproduce the problem and fix it if so.
