求助：集成easeUI时报already added: Landroid/support/annotation/ColorRes;

初次使用环信，在AndroidStudio中新建一空白项目，将easeUI以module的形式引入，构建没问题，单一运行重新构建时就报错：

UNEXPECTED TOP-LEVEL EXCEPTION:

com.android.dex.DexException: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

 FAILED



FAILURE: Build failed with an exception.

既然说重复引入了v4包，难道我要将easeUI的lib下的supportV4删除么？删了的话，easeUI直接报错，找不到相关v4资源；
自己工程的build.gradle:

apply plugin: 'com.android.application'



android {



    compileSdkVersion 23

    buildToolsVersion "23.0.2"



    defaultConfig {

        applicationId "austin.com.huanxintest"

        minSdkVersion 14

        targetSdkVersion 20

        versionCode 1

        versionName "1.0"

    }



    buildTypes {

        release {

            minifyEnabled false

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }

    }

}



dependencies {

    compile fileTree(dir: 'libs', include: ['*.jar'])

    testCompile 'junit:junit:4.12'

    //    compile 'com.android.support:appcompat-v7:23.2.1'

    compile 'com.android.support:design:23.2.1'

    compile project(':easeui')

}

easeUI的build.gradle:

apply plugin: 'com.android.library'



android {

    compileSdkVersion 19

    buildToolsVersion "23.0.1"



    defaultConfig {

        minSdkVersion 9

        targetSdkVersion 20

    }

	

	sourceSets {

        main {

            manifest.srcFile 'AndroidManifest.xml'

            java.srcDirs = ['src']

            resources.srcDirs = ['src']

            aidl.srcDirs = ['src']

            renderscript.srcDirs = ['src']

            res.srcDirs = ['res']

            assets.srcDirs = ['assets']

            jniLibs.srcDirs = ['libs']

        }



        // Move the tests to tests/java, tests/res, etc...

        instrumentTest.setRoot('tests')



        // Move the build types to build-types/

        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...

        // This moves them out of them default location under src//... which would

        // conflict with src/ being used by the main source set.

        // Adding new build types or product flavors should be accompanied

        // by a similar customization.

        debug.setRoot('build-types/debug')

        release.setRoot('build-types/release')

    }



    buildTypes {

        release {

            minifyEnabled false

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'

        }

    }

}



dependencies {

	//release时需要把easemobchatsdk的依赖注释掉，sdk已经被打成jar包放在libs底下

	//compile project(':hyphenatechatsdk')

    compile fileTree(dir: 'libs', include: '*.jar')

}

另外，minifest.xml 和 BaseApplication已经按照文档做了集成修改。
求环信各位大神指教，感激不尽。。。。
