android - .DexArchiveMergerException：无法合并 dex

问题描述

通过android studio开发android系统应用环境。

  1. 将/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar复制到app/libs。重命名framework.jar

  2. 添加 provided fileTree(dir: 'libs', include: ['*.jar']) 到build.gradle

  3. 添加options.compilerArgs << '-Xbootclasspath/p:app\\libs\\framework.jar'

重建项目时，发生错误

解决方案

此错误app:transformDexArchiveWithExternalLibsDexMergerForDebug通常是由于添加了可能与您的compileSdkVerison.

在您的项目中启用 Multidex。要启用它打开build.gradle(Module:app)文件，然后在defaultConfig块中写入multidexEnabled true。

现在，清理并重建您的项目。
