class=”keylink”>vcD4KPHByZSBjbGFzcz0=”brush:java;”>dependencies { compile fileTree(dir: ‘libs’, include: [‘*.jar’]) compile ‘com.android.support:appcompat-v7:21.0.0’ compile ‘in.srain.cube:cube-sdk:1.0.42.1’ compile files(‘libs/android-async-http-1.4.6.jar’) }其中引入了v7的包后会自动去加载编译一个v4:21.0.0包，而在in.srain.cube:cube-sdk:1.0.42.1库中也有一个v4的包，所以我们需要去掉一个
看一下，libraries是否是我们所讲的那样，重复加载v4包\\二、解决办法?12345678dependencies {compile fileTree(dir: 'libs', include: ['*.jar'])compile 'com.android.support:appcompat-v7:21.0.0'<span style="color:#ff0000;">compile ('in.srain.cube:cube-sdk:1.0.42.1'){exclude module: 'support-v4'}</span>compile files('libs/android-async-http-1.4.6.jar')}去掉in.srain.cube:cube-sdk:1.0.42.1中的包不加载即可。
