ptrace(PTRACE_TRACEME,0 ,0 ,0);这个方案确定好使？依然可以调试呀

LOGI("ret of ptrace : %d",check);
std::string hello = "Hello from ptrace";
if(check != 0){
hello = "Debug from ptrace";
}
return env->NewStringUTF(hello.c_str());
}

any updates on this? i find in a stackoverflow comment that ptrace command needs root accesss so this code snippet ptrace(PTRACE_TRACEME,0,0,0) , always gonna reurn -1(error) ... is there any other alternatives found?
