SDKBOX issue with GPS services multidex

@nite @yinjimmy

Hi, we updated sdkbox to latest version and seems there is some issue with google play services when enabling multidex.

We getting issue about duplicated entry com/google/android/gms/internal/zzcfo.class

After rollbacking gps version to previos sdkbox version everything compiled, is there some special requirments to use latest sdkbox bundled gps in project?

I am also having similar issues with latest (cocos 3.17 and latest sdkbox) with the facebook plugin.

:MyApp:transformClassesWithMultidexlistForDebug FAILED

FAILURE: Build failed with an exception.

I tried re-importing with latest without luck:

sdkbox import share --forcedownload --staging
sdkbox import facebook --forcedownload --staging

Thank you all reporting this issue.

@praubic , what plugins do you have in your project ? Is here more than one support-v4 jar.

plz help to check:

$ find . -name "*support-v4*"

UPDATE: I reproduce this issue.


  1. sdkbox import facebook
  2. cocos compile -p android
  3. sdkbox import admob
  4. cocos compile -p android

  1. remove ./cocos2d/cocos/platform/android/java/libs/android-support-v4.jar
  2. cleanup
  3. compile again.

I’ll figure out how to solve this issue, android studio compile failed even the android-support-v4.jar is same.

~/test/cpp317 [master] $ md5 ./cocos2d/cocos/platform/android/java/libs/android-support-v4.jar
MD5 (./cocos2d/cocos/platform/android/java/libs/android-support-v4.jar) = 79ab7eaf6666d4815294110c713ed64d
~/test/cpp317 [master] $ md5 ./cocos2d/cocos/platform/android/java/libs/android_support_v7/appcompat/libs/android-support-v4.jar
MD5 (./cocos2d/cocos/platform/android/java/libs/android_support_v7/appcompat/libs/android-support-v4.jar) = 79ab7eaf6666d4815294110c713ed64d

@energyy, whats your plugins? And is there any other google play services ? whats your cocos2d-x version?

We using sdkboxplay, iap, analytics plugins, cocos2d-x 3.15.

I was also trying to remove android-v4, but then it failed to compile due missing it, what I found in interent there is some strange bug in latest gps itself when it compiled in multidex mode - so not sure if we can fix it or just need to use different gps version.

It seems I found what we had issue with latest GPS it’s conflicting with sdkbox-firebase.jar file, after deliting it everything gg
ot compiled

i import firebase on cpp 3.15.1 and 3.17, both can compile success.

and , i unzip sdkbox-firebase.jar, there is no zzcfo.class in it. so it’s not sdkbox-firebase.jar cause conflicting
