今天在工作中碰到了一个加载fresco这个框架，碰到了suport包重复引用的问题，一是本身应用上需要应用，但是fresco中又包含有该报，导致在果然掉了在编译的时候出现错误：

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: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompatIcs;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)

解决的方法就是

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

改成

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'){        exclude module: 'support-v4'    }    compile files('libs/android-async-http-1.4.6.jar')}
