java getmethodid,JNI在应用程序中检测到错误：JNI GetMethodID调用挂起异常java.lang.ClassNotFoundException：未找到类...

我收到以下错误：

JNI DETECTED ERROR IN APPLICATION：JNI GetMethodID调用挂起异常java.lang.ClassNotFoundException：未在路径上找到类“package.name.class”：DexPathList [[zip file“/system/framework/sample.jar”] ，nativeLibraryDirectories = [/ vendor / lib，/ system / lib]]

这里有更多关于错误的信息：

`jmethodID MethodId;
