MultiDex support in Android application error

Question

I want to use Android L compat libs. after adding the relevant code to gradle, I get the error:

  Error Code:
2
  Output:
objc[36290]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

I saw questions about it this here and here, and tried out the solution from this blog post, and I still get an error, where in the case of the blog post, I get:

  Error Code:

These are my android gradle settings:

android {
compileSdkVersion 21
buildToolsVersion "20.0.0"

defaultConfig {
    applicationId "com.my.package"
    minSdkVersion 9
    targetSdkVersion 21
}

buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
    }
}

}

These are my dependencies:

dependencies {
compile project(':libraries:ecoGallery')
compile project(':libraries:facebookSDK')
compile 'com.android.support:support-v4:21.0.0'
compile 'com.android.support:appcompat-v7:21.0.0'
compile 'com.google.android.gms:play-services:6.1.71'

compile 'com.nineoldandroids:library:2.4.0'
compile 'oauth.signpost:signpost-commonshttp4:1.2.1.2'
compile 'oauth.signpost:signpost-core:1.2.1.2'
compile 'com.uservoice:uservoice-android-sdk:+@aar'
compile 'com.newrelic.agent.android:android-agent:4.87.0'
compile 'com.google.guava:guava:18.0'
compile files('libs/android-support-multidex.jar')

}

Does anyone have any ideas for what I might be doing wrong?

Answer 1

Gradle plugin v0.14.0 for Android adds full multidex support.
Remove all the build.gradle changes you made (for multidex), and simply add the following:

android {
   defaultConfig {
      ...
      multiDexEnabled = true
   }
}
