I have the same issue, last week it was building correctly.

[danilopolani]

Same here. Yesterday was fine, today this breaks the build. My version of the plugin is 6.0.6.

[yosi-dediashvili]

Same story here. Not sure what got updated, and where :\

[yosi-dediashvili]

@amit-t, can you share the plugin list you have? I have a feeling that it might be related to other plugin causing a mess?

[iowaz]

@yosi-dediashvili , here's go mine:

com.telerik.plugins.nativepagetransitions 0.6.5 "Native Page Transitions"
cordova-android-play-services-gradle-release 0.0.2 "cordova-android-play-services-gradle-release"

phonegap-plugin-barcodescanner 6.0.7 "BarcodeScanner"
phonegap-plugin-push 1.10.5 "PushPlugin"

[iowaz]

See, the problem is that Facebook SDK recently included ZXing as a dependency.

jeduan/cordova-plugin-facebook4#550

[yosi-dediashvili]

OK, so the issue here is with the underlying module. The barcodescanner-lib-aar: https://github.com/EddyVerbruggen/barcodescanner-lib-aar/tree/master/barcodescanner/src/main/java/com/google/zxing

Seems like instead of depending on the barcode lib, it's including the whole source, essentially redefining everything, and that's why the build fails (there's the lib being included because of the Facebook SDK, and the lib getting redefined by the barcode lib).

Seems like forcing version 4.25.0 of the Facebook SDK (if you don't need 4.26.0), solves this. Add a after_platform_add hook:

if [ -d "platforms/android" ]; then
  echo '
configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == "com.facebook.android") {
          details.useVersion "4.25.0"
        }
    }
}
' > platforms/android/build-extras.gradle
fi

[amit-t]

@yosi-dediashvili - Here is my list

cordova-plugin-calendar 4.6.0 "Calendar"
cordova-plugin-camera 2.4.1 "Camera"
cordova-plugin-compat 1.1.0 "Compat"
cordova-plugin-console 1.0.7 "Console"
cordova-plugin-datepicker 0.9.3 "DatePicker"
cordova-plugin-device 1.1.6 "Device"
cordova-plugin-facebook4 1.9.1 "Facebook Connect"
cordova-plugin-googleplus 5.1.1 "Google SignIn"
cordova-plugin-inappbrowser 1.7.1 "InAppBrowser"
cordova-plugin-splashscreen 4.0.3 "Splashscreen"
cordova-plugin-statusbar 2.2.3 "StatusBar"
cordova-plugin-whitelist 1.3.2 "Whitelist"
cordova-plugin-wkwebview-engine 1.1.4-dev "Cordova WKWebView Engine"
ionic-plugin-keyboard 2.2.1 "Keyboard"
phonegap-plugin-barcodescanner 6.0.8 "BarcodeScanner"

[Ross-Rawlins]

Where does the hook get added? in the build gradle?

[danilopolani]

@Ross-Rawlins you can create the path hooks/after_platform_add/ in your project root and inside that create a file called facebook4-fix.sh (the name doesn't matter, but it must be .sh) and put the code inside that file.

Then remove and readd android platform.
If you are using Ionic the folder may already exists with a detailed README, just make sure to delete it from .gitignore or, if you are using git, the hooks will never be sent with the push.

[Ross-Rawlins]

oh i added the file build-extras.gradle and its all working now?

[danilopolani]

@Ross-Rawlins yes, but if you choose to create manually the file, remember to exclude it from .gitignore (which ignores all the platforms).

Put !platforms/android/build-extras.gradle after platforms/, for example:

tmp/
temp/
platforms/
!platforms/android/build-extras.gradle
plugins/
plugins/android.json

P.S. This is extracted from a Ionic project .gitignore, it may change if you aren't using it

[dgaurav-163]

I am getting same problem, Where I have to add hack in code repository. I have already build-extras.gradle file inside cordova-plugin-file -> src -> android -> build.extras.gradle. same file is blank so what I have to add in tthis file? Did nou understand why you are adding hack for facebook.

Kindly suggest!

[danilopolani]

@dgaurav-163 the "hack" is for Facebook because it now includes the barcodescanner, so there are two duplicates.

You have to copy-paste that code inside your platforms/android/build-extras.gradle file, not the one of the plugin.

[Maik3345]

if [ -d "platforms/android" ]; then
  echo '
configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == "com.facebook.android") {
          details.useVersion "4.25.0"
        }
    }
}
' > platforms/android/build-extras.gradle
fi

create the hook not work for me, but adding this in the end of the build.gradle and work correctly!!

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == "com.facebook.android") {
          details.useVersion "4.25.0"
        }
    }
}

[danilopolani]

Maik did you removed android and added again with the command platform rm android and platform add android? The hook is called only when you add the platform, not when you deploy the app

[Maik3345]

yeah, remove the platform but not work the hook, but add this code in the gradle and work.

[Ross-Rawlins]

I copied the exact code into the file it says and it works perfectly.

same issue will remove when I add multiDexEnabled true in build.gradle inside defaultConfig.

defaultConfig {
minSdkVersion 14 //lower than 14 doesn't support multidex
targetSdkVersion 22

         // Enabling multidex support.
         multiDexEnabled true
     }

try this, may be it will help

[amit-t]

I was able to fix it by doing the below :-
in the file "project.properties"
Change the below three lines ...

cordova.system.library.2=com.facebook.android:facebook-android-sdk:+
cordova.system.library.3=com.google.android.gms:play-services-auth:+
cordova.system.library.4=com.google.android.gms:play-services-identity:+

TO

cordova.system.library.2=com.facebook.android:facebook-android-sdk:4.25.0
cordova.system.library.3=com.google.android.gms:play-services-auth:9.0.0
cordova.system.library.4=com.google.android.gms:play-services-identity:9.0.0

[vagnerbertoni]

just fix facebook plugin version
<gap:plugin name="cordova-plugin-facebook4" source="npm" spec="1.7.4">

[lorecioni]

I followed the solution proposed by @amit-t and got it work! Thank you!
The only change I made:

cordova.system.library.2=com.facebook.android:facebook-android-sdk:4.25.0

[baptistedeleplace]

Thanks @vagnerbertoni !

[upuxaa]

I couldn't figure it out...just added this plugin and it worked: https://github.com/NazarKozak/cordova-plugin-multidex

[dgaurav-163]

Thanks @Maik3345. your solution worked for me. 👍

[AnthonyLombard]

I dont have the facebook plugin and I still get this error< have tried everything above to no avail.

Here is my plugin list

cordova-plugin-compat 1.1.0 "Compat"
cordova-plugin-device 1.1.5 "Device"
cordova-plugin-dialogs 1.3.2 "Notification"
cordova-plugin-multidex 1.0 "Cordova Multi Dex"
cordova-plugin-whitelist 1.3.2 "Whitelist"
phonegap-plugin-barcodescanner 6.0.6 "BarcodeScanner"

I just added multidex as above comment said it may work

[wilsolutions]

Using com.facebook.android:facebook-android-sdk:4.25.0 works =) but

FB SDK is now on version com.facebook.android:facebook-android-sdk:4.37.0 so, we need to upgrade.

Is it possible to make the barcodescanner plugin to use the same version of the zxing library (com.google.zxing:core:3.3.0) as the FB SDK?

[xale76]

please someone could help me?
even if I add

I got still the error!

[yurik94]

Any news?

[FlossyWeb]

[JustasKuizinas]

Did no one solve this?

[viking2917]

@JustasKuizinas See workarounds mentioned in this issue: #606. Key seems to be retreating to Facebook login plugin v 1.7.4. Not a fix but can work with older facebook plugin versions.

[JavierPAYTEF]

This issue is still happening. But now it's worst because the facebook4 plugin introduced some new features that make it incompatible with SDK version 4.25, so now you also have to install an older version of the plugin itself.
Is there no way around the use of the aar file? Is the codebase to big to include the code instead?

[JavierPAYTEF]

In case anyone needs it the last compatible version is 3.2.0 (the current is 4.2.1).
You can install it like this:

cordova plugin add cordova-plugin-facebook4@3.2.0 --save --variable APP_ID="123456789" --variable APP_NAME="yourappname" --variable FACEBOOK_ANDROID_SDK_VERSION="4.25.0"

You might also need to add multidex, like some other answers explain. There are cordova plugins for that as well.

[idpsycho]

Nothing worked. I tried every suggestion I found in this thread, on stackoverflow, and on the internet. Nothing helped me. phonegap-plugin-barcodescanner just wont coexist with cordova-plugin-facebook4. I ended up removing phonegap-plugin-barcodescanner and used cordova-plugin-qrscanner instead.

Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

Thank you, @viking2917! I finally found a solution. Not that best one, but it works.

Adding in build.gradle:

compile ("com.facebook.android:facebook-android-sdk:4.40.0"){

Hello, could you explain me where to put that code? i have been trying to solve this issue, but when i try to use

compile ("com.facebook.android:facebook-android-sdk:4.40.0"){
exclude group: 'com.google.zxing'
}

It doesnt make any effect since the build.grandle gets rebuilt everytime i try cordova build.

Thanks

I have a fix for this !
I forked the facebook plugin and excluded that library with exclude group: 'com.google.zxing'.
Here is my fork: https://github.com/AndreiTelteu/cordova-plugin-facebook4-no-zxing
To install my fork, do this:

cordova plugin rm cordova-plugin-facebook4
cordova plugin add cordova-plugin-facebook4-no-zxing --save --variable APP_ID="123456789" --variable APP_NAME="myApplication"

@AndreiTelteu , thank you!

@AndreiTelteu very nice, thank you!
is there any way that your build.gradle uses the FACEBOOK_ANDROID_SDK_VERSION preference?
also, is there any way to add a FACEBOOK_ANDROID_SDK_EXCLUDE_ZXING preference, which would default to false, and use it to exclude zxing or not?
with those 2 improvements, your changes could be integrated in the main facebook4 plugin

[JustasKuizinas]

@AndreiTelteu could your changes be integrated into the main cordova-plugin-facebook4 with optional parameters to enable/disable ZXING ?

In my opinion, since the root cause is that this plugin provides it's own (slightly customized) aar version of the library instead of linking to the maven dependency, it's up to this plugin to be configured so it'll add the com.google.zxing group to the compile excludes.

If the plugin maintainer(s) simply add the snippet below to the src/android/barcodescanner.gradle file it should resolve this conflict as well as conflicts with other plugins that import the zxing library from maven.

configurations {
    compile.exclude group: 'com.google.zxing'
}

If at all possible, I'd actually suggest doing a "clean" import of zxing instead, but that depends on what kind of customizations there are in the "aar" file and if these customizations could also be done without the use of said aar file.

Reproduced a very similar problem with same root cause. Error messages in particular were:

> Task :app:transformClassesWithDexBuilderForDebug

D8: Program type already present: com.google.zxing.DecodeHintType

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:

  Program type already present: com.google.zxing.DecodeHintType

Versions:

Cordova 9.0.0 (cordova-lib@9.0.1)
cordova-android@8.1.0
cordova-plugin-facebook4@6.0.0
phonegap-plugin-barcodescanner@8.1.0

Many thanks @chancezeus for this analysis. I've suggested the change in src/android/barcodescanner.gradle as PR for a minimal fix.

For reference, #614 seems a duplicate.

Thanks, it worked here.
