看堆栈是因为xml没有被正确修改，这是修改过程是插件做的，会把JavaContentProvider修改为JavaContentProvider_decorated，试试命令行的方式安装：
./gradlew qigsawInstallDebug

我也遇到这个问题，是用as的Run Configurations 去除Dynamic features to deploy 的 java模块重现，选中就正常，去除就是这个错； 另外使用qigsawInstallDebug命令行正常； 这个是什么原因，有大佬解答一下吗

因为用AS的run，是把每个feature都打包成一个apk，然后通过 adb install-multiple安装的，这是系统支持的分包，不需要走qigsaw的插件加载流程。如果你去掉了java，那安装的时候就会少了java那个apk，里面的类JavaContentProvider当然会找不到了。
