java 调用在一些平台会得不到结果，打印：

需确保你的内核编译config中：

CONFIG_ANDROID_PARANOID_NETWORK=n

C :

code

#include<stdlib.h>
#include <stdio.h>
#include <sys/wait.h>

#define SLOGE printf

int isSystemSuccessful(pid_t status)
{
        if(-1 == status || 127 == status){
          SLOGE("system error!!");
          return -1;
          }else{
               if(WIFEXITED(status)){
                 SLOGE("run shell script success, script exit code: %d\n",WEXITSTATUS(status));
                 return 0;
                }else{
                 SLOGE("exit status = [%d]\n",WEXITSTATUS(status));
                 return -1;
                }
           }

}


int main(int argc, char **argv)

        if(isSystemSuccessful(status) != 0) {
