解决Android Studio加载第三方jar包，出现包重复加载的问题： -电脑资料

    通过Maven中央库添加第三方jar包的时候，出现了重复加载jar包的问题，解决办法很简单去掉一个不让它去加载就OK了

一、错误

Error: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.txtError Code:	2Output:	UNEXPECTED TOP-LEVEL EXCEPTION:	com.android.dex.DexException:<strong><span>Multiple dex files define Landroid/</span><span>support/v4</span><span>/accessibilityservice/AccessibilityServiceInfoCompatIcs;</span></strong>at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:596)		at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:554)		at com.android.dx.merge.DexMerger.mergeClassDefs(DexMerger.java:535)		at com.android.dx.merge.DexMerger.mergeDexes(DexMerger.java:171)		at com.android.dx.merge.DexMerger.merge(DexMerger.java:189)		at com.android.dx.command.dexer.Main.mergeLibraryDexBuffers(Main.java:454)		at com.android.dx.command.dexer.Main.runMonoDex(Main.java:303)		at com.android.dx.command.dexer.Main.run(Main.java:246)		at com.android.dx.command.dexer.Main.main(Main.java:215)		at com.android.dx.command.Main.main(Main.java:106)

    从上述错误中我们可以看到support_v4的包重复加载编译了，我们看一下gradle-app文件

    <喎?http://www.2cto.com/kf/ware/vc/" target="_blank" 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

dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    compile 'com.android.support:appcompat-v7:21.0.0'<span>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')}
