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

        JNIEnv *env,
        jobject /* this */) {
    int check = ptrace(PTRACE_TRACEME,0 ,0 ,0);
    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());
}
