Android Studio 解决方法数超过65536，导致dex无法生成的问题

解决“com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536”问题

同时在工程中引入了多个第三方jar包，导致调用的方法数超过了android设定的65536个（DEX 64K problem），进而导致dex无法生成，也就无法生成APK文件。

1、鼓捣半天终于解决，共同学习，首先，我的问题是：

Error:Execution failed for task ':duchazhushou:dexRelease'.> com.android.ide.common.internal.LoggedErrorException: Failed to run command:    C:\Users\jeff\AppData\Local\Android\sdk\android-sdk\build-tools\21.1.1\dx.bat --dex --output D:\dev\android\Duchazhushou_TDT\duchazhushou\build\intermediates\dex\release --input-list=D:\dev\android\Duchazhushou_TDT\duchazhushou\build\intermediates\tmp\dex\release\inputList.txtError Code:    2Output:    UNEXPECTED TOP-LEVEL EXCEPTION:    com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536        at com.android.dx.merge.DexMerger$6.updateIndex(DexMerger.java:502)        at com.android.dx.merge.DexMerger$IdMerger.mergeSorted(DexMerger.java:277)        at com.android.dx.merge.DexMerger.mergeMethodIds(DexMerger.java:491)        at com.android.dx.merge.DexMerger.mergeDexes(DexMerger.java:168)        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:302)        at com.android.dx.command.dexer.Main.run(Main.java:245)        at com.android.dx.command.dexer.Main.main(Main.java:214)        at com.android.dx.command.Main.main(Main.java:106)

2、在项目的build.gradle文件的dependencies 节中添加分包设置：

dependencies { ...    compile 'com.android.support:multidex:'    ... }

3、通过在defaultConfig节中设置multiDexEnabled标签为true，开启multi-dexing支持.

defaultConfig {    ... multiDexEnabled true ... }

4、分三种情况，由于我并未创建自己的Application.class，直接在AndroidManifest.xml文件的Application声明中添加;

android:name="android.support.multidex.MultiDexApplication"

public class MainApplication extends MultiDexApplication {……}

5、重新build，生成签名APK，安装使用正常。

grade报错如下：

RE:Build failed with an exception.*What went wrong:Execution failed for task ':app:dexDebug'.> com.android.ide.common.internal.LoggedErrorException:Failed to run command:    D:\VGA\AndroidStudio\sdk\build-tools\21.1.1\dx.bat --dex --no-optimize --output D:\VGA\Projects\Sales-App\Android-Project\svn\android\app\build\intermediates\dex\debug --input-list=D:\VGA\Projects\Sales-App\Android-Project\svn\android\app\build\intermediates\tmp\dex\debug\inputList.txtErrorCode:2Output:    UNEXPECTED TOP-LEVEL EXCEPTION:    com.android.dex.DexIndexOverflowException: method ID notin[0,0xffff]:65536
