加固后运行失败Unable to instantiate activity ComponentInfo

没加固的时候可以正常运行
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.jy.zydsj/com.jy.zydsj.LoadingActivity}: java.lang.ClassNotFoundException: Didn't find class "com.jy.zydsj.LoadingActivity" on path: DexPathList[[zip file "/data/app/com.jy.zydsj-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.jy.zydsj-1, /vendor/lib, /system/lib]]

您好  请按照以下操作进行尝试 原包在签名工具中签名----提交加固----下载加固包在签名工具在签名
如还是提示找不到类 请在于我司联系 谢谢
