android在ndk/jni的cc/c ++中获取imei [英] android get imei in cc/c++ for ndk/JNI

问题描述

我会尝试使用C/C ++(使用ndk)获取设备的imei，并使用JNI检索结果.

I would try to get the imei of a device in C/C++ (using ndk) and retrieve the result with JNI.

const char *res = exec_get_out("service call iphonesubinfo 3");

可以在shell中使用，但不能在我的应用程序中使用

Works in shell, but does not in my application

我在清单中设置了READ_PHONE_STATE权限.这是针对棉花糖Android系统的(并且我已经接受设置的权限)

I have the READ_PHONE_STATE permission set in the Manifest. This is targeted for Marshmallow Android (and I have accepted permission in settings)

还有其他解决方案是否可行?如果没有JNI环境，是否不可能?

Is there any other solution that would work or is it not possible without a JNI environment?

推荐答案

检查此

#include <sys/system_properties.h>

    //returns the string length of the value.
    int ir = __system_property_get("ro.gsm.imei", imei_start);           

      if(ir > 0)
    {
      imei_start[15]=0;//strz end      
      printf("method1 got imei %s len %d\r\n",imei_start,strlen(imei_start));
      strcpy(g_imei,imei_start);
    }
      else
    {
      printf("method1 imei failed - trying method2\r\n");
      //old dumpsys imei getter
      char* res = exec_get_out("dumpsys iphonesubinfo");  
      const char* imei_start_match = "ID = ";
      int imei_start_match_len = strlen(imei_start_match);
      char* imei_start = strstr(res,imei_start_match);
      if(imei_start && strlen(imei_start)>=15+imei_start_match_len)
        {
          imei_start += imei_start_match_len;
          imei_start[15] = 0;
          printf("method2 IMEI [%s] len %d\r\n",imei_start,strlen(imei_start));
          strcpy(g_imei,imei_start);
        }
    }
