解決Android Studio加載第三方jar包，出現包重複加載的問題

今天在工作中碰到了一個加載fresco這個架構，碰到了suport包重複引用的問題，一是本身應用上需要應用，但是fresco中又包含有該報，導緻在果然掉了在編譯的時候出現錯誤：

Execution failed for task ':app:dexDebug'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
	F:\zsl\sdk\build-tools\21.1.2\dx.bat --dex --output F:\zsl\Android\pro\RecipesDaquan\app\build\intermediates\dex\debug --input-list=F:\zsl\Android\pro\RecipesDaquan\app\build\intermediates\tmp\dex\debug\inputList.txt

解決的方法就是
           

compile 'com.android.support:appcompat-v7:21.0.0'
    compile ('in.srain.cube:cube-sdk:1.0.42.1'){
        exclude module: 'support-v4'
    }
    compile files('libs/android-async-http-1.4.6.jar')
}
