小编yog*_*arl的帖子

我在Android应用程序中使用Dagger.它在应用程序中工作,但是当我运行检测测试时,我得到一个NoClassDefFoundError.

我正在使用Gradle和Espresso.没有progaurd就会发生这种情况.

这很奇怪,因为"Module $$ ModuleAdapter"被加载,但"Module $$ ModuleAdapter $ EndpointProvidesAdapter"却没有.

我将APK从设备中拉回来并使用dexdump验证该类确实在APK中,"Module $$ ModuleAdapter $ EndpointProvidesAdapter".

关于可能导致这种情况的任何想法？

如果您使用的是com.android.tools.build:gradle:0.10.0和gradle 1.12,则可能会出现此错误.
