Thank you for reporting this issue. For us to further investigate this issue, please provide the following additional information:

Android build
Which Android build are you using? (e.g. UQ1A.240205.002)

Device used
Which device did you use to reproduce this issue?

Are you reporting this as a Developer or User?

Android bug report (to be captured after reproducing the issue)
For steps to capture a bug report, please refer: https://developer.android.com/studio/debug/bug-report#bugreportdevice

Alternate method
Navigate to “Developer options”, ensure “USB debugging” is enabled, then enable “Bug report shortcut”.  Capture bug report by holding the power button and selecting the “Take bug report” option.

Note: Please upload the bug report to google drive and share the folder to android-bugreport@google.com, then share the link here.

@2 the only think you can do is manually edit the aar, and the classes.jar inside to remove the offending BuildConfig.class since it's not used anyway.

@1 Is there a timeline on the fix for this?

As a workaround you can remove multidex-instrumentation from dependencies, copy test runner to your app (https://android.googlesource.com/platform/frameworks/multidex/+/master/instrumentation/src/com/android/test/runner/MultiDexTestRunner.java) and set new runner to testInstrumentationRunner in defaultConfig.

The Android support repository now has version 1.0.1 of the multi-dex libraries. You'll need to manually add a dependency on them (since the plugin only adds a dependency on 1.0.0)

I confirm this specific bug is fixed with v1.0.1. Thank you.

Hi Devs,
I just moved to Android Studio because Eclipse build system does not support multidex solution.
but with android studio I am facing the same problem, Please guide me.

My build.gradle:
apply plugin: 'com.android.application'

android {
    compileSdkVersion 'Google Inc.:Google APIs:21'
    buildToolsVersion "21.1.2"
   
    defaultConfig {
        applicationId "com.myapp.appname"
        minSdkVersion 14
        targetSdkVersion 21
        multiDexEnabled true
    }

    buildTypes {

        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
        }
    }

   
}

dependencies {

    compile project(':androidsupportmultidex')
    compile files('libs/android-support-v13.jar')
    compile files('libs/json-simple-1.1.1.jar')
    compile files('libs/libGoogleAnalyticsServices.jar')
   
}

ERROR:
* What went wrong:
Execution failed for task ':myapp:packageAllDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: android/support/multidex/BuildConfig.class

Please Reply.

Thanks in advance.

Hi,
I have the same problem, any updates?

Best Regards,
Gospodin Bodurov

Anyone? Anything?

Hi,
I have the same problem, any updates?

Hello, it still has the same problem on Android Studio 1.2.2. Any update of the issue?

same issue here!! is anybody out there?

Have the same problem with android studio 1.2.2. Please update on this

Make sure there are no duplicate library dependencies. Adding jar as well as maven dependency of same library can also cause this problem. Also make sure that even dependency modules should not contain same libraries.

I have the same problem, any updates?

Still the same issue on AndroidStudio 1.4 ... any timeframe for the solution??

I am also facing same problem in Android studio 1.4.. any luck??

Still facing the same issue after adding play_services-gcm in the dependencies. Any luck??

I have also facing same issue when i import my existing project please find my greadle

For those who still having an issue - please check if some of your dependencies have multidex as dependency and exclude it. For example for Facebook SDK:

    compile('com.facebook.android:facebook-android-sdk:+') {
        exclude group: 'com.android.support', module: 'multidex'
    }

When i want to compile into APK-release, i get the same problem in android studio but i can normally compile into debug version
