com.android.dex.DexException: Multiple dex files define in android app

[BlakeRxxk]

After adding react-native-firestack I've got this error

UNEXPECTED TOP-LEVEL EXCEPTION:

Any ideas?

Thanks

I just had this error, this is how I managed to fix it.

Change
compile project(':react-native-firestack')
To
compile(project(':react-native-firestack')){ exclude group: 'com.google.android.gms' }

On your android/app/build.gradle file.

Hope it works for you!

@GDuarteL, thank you! work like a charm!

I'm facing the same issue here,
these are my dependencies in app/build.gradle

dependencies {
    compile(project(':react-native-firestack')){
        exclude group: "com.google.android.gms" // very important
    }
    compile project(':react-native-facebook-login')
    compile project(':react-native-vector-icons')
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "com.android.support:appcompat-v7:23.0.1"
    compile "com.facebook.react:react-native:+"
    compile(project(":react-native-google-signin")){
        exclude group: "com.google.android.gms" // very important
    }
    compile 'com.google.android.gms:play-services-auth:9.2.1' // should be at least 9.0.0
}

Do you see something that may be causing problems?

[jdmunro]

@maggialejandro I had this issue too even after the fixes. I was able to solve it by loosening the dependencies in the gradle file for firestack as mentioned in #290. I don't know if there's any intention of merging this.

Go the Gradle and move cursor on each library if there is updated version available then update the library then sync the Gradle. Actually I was up to this problem for 2 days I tried every method but did not solve it. then I updated the library, sync the gradle and run agian. it worked for me.

@Opriday yes this worked for me. Thanks

Hi guys,

I have this combination of dependencies. Does anyone know which one is to be changed, and to what? The bold lines are the ones with problems.

Thanks
