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。
解决办法如下:
1、谷歌官方已经给出了相关的文档,参照网上搜索的资料,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.txt Error Code: 2 Output: 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"
5、重新build,生成签名APK,安装使用正常。
以上步骤均参考下面链接操作,关于第4步的另外两种情况,在下面链接中均有详细说明:
