frida hook返回值是一个反射对象

sign-cc commented 3 weeks ago

看起来像是Systemcall报错了，handleInterrupt intno=2, NR=-130880, svcNumber=0x103, 但是查系统调用表查不到对应的值

但是看报错异常仿佛是反射方法pointer 找不到

createnewdemo commented 2 weeks ago

哥们 解决了吗？我也遇到了；

sign-cc commented 2 weeks ago

@createnewdemo 没，要不要一起研究研究，我问了下其它人说都不行

createnewdemo commented 2 weeks ago

q320783214 一起研究一下

sign-cc commented 2 weeks ago

但是从trace 的情况来看 返回的是一个MethodId
