我尝试了各种构建工具版本和支持版本。但我无法修复此错误。但是，如果我将 multiDeskEnabled 更改为 false，则一切正常。因此，对于 multiDeskEnabled，相同的依赖项不起作用。
当我搜索解决方案时，我发现很少有关于保持更改构建顺序等的建议，这些建议与 Eclipse 相关。但我找不到任何适用于 Android 的解决方案。谁能帮我解决这个问题？
最佳答案
您缺少一些在 <5.0 设备上运行所需的额外功能。
- 您的 gradle 依赖项中需要这个:
compile 'com.android.support:multidex:1.0.0' - 您需要将 list 中的应用程序更改为 multidex 应用程序，或者在您的自定义应用程序类中覆盖
attachBaseContext()以在之后调用MutiDex.install(this)super.attachBaseContext(base);
您可以在此处查看完整的文档(可能会在您发布后更新)https://developer.android.com/tools/building/multidex.html#mdex-gradle .请参阅“使用 Gradle 为 Multidex 配置您的应用程序”部分。
关于Android Multidex 和支持库，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27340058/
