android 接收can总线数据？我有c的事例 我看到他用的SocketCan，android的怎么写？
请问有谁解决过这个问题吗？不要论坛里面有过的那个解决方案？我把c的代码贴出来：
这是接收端的：
#include <string.h>
#include <sys/ioctl.h>
#include <net/if.h>
#include <linux/can.h>
#ifndef PF_CAN
#define PF_CAN 29
#endif
#ifndef AF_CAN
#define AF_CAN PF_CAN
#endif
int main()
{
int s;
unsigned long nbytes,len;
struct sockaddr_can addr;
struct ifreq ifr;
struct can_frame frame;
s = socket(PF_CAN,SOCK_RAW,CAN_RAW);
strcpy(ifr.ifr_name,"can0");
ioctl(s,SIOCGIFINDEX,&ifr);
printf("can0 can_ifindex = %x\n",ifr.ifr_ifindex);
//bind to all enabled can interface
addr.can_family = AF_CAN;
addr.can_ifindex =0;
bind(s,(struct sockaddr*)&addr,sizeof(addr));
nbytes = recvfrom(s,&frame,sizeof(struct can_frame),0,(struct sockaddr *)&addr,&len);
/*get interface name of the received CAN frame*/
ifr.ifr_ifindex = addr.can_ifindex;
ioctl(s,SIOCGIFNAME,&ifr);
printf("Received a CAN frame from interface %s\n",ifr.ifr_name);
printf("frame message\n"
"--can_id = %x\n"
"--can_dlc = %x\n"
"--data = %s\n",frame.can_id,frame.can_dlc,frame.data);
return 0;
}
这是发送端的：
#include <string.h>
#include <sys/ioctl.h>
#include <net/if.h>
#include <linux/can.h>
#ifndef PF_CAN
#define PF_CAN 29
#endif
#ifndef AF_CAN
#define AF_CAN PF_CAN
#endif
int main()
{
int s;
unsigned long nbytes;
struct sockaddr_can addr;
struct ifreq ifr;
struct can_frame frame;
s = socket(PF_CAN,SOCK_RAW,CAN_RAW);
strcpy((char *)(ifr.ifr_name),"can0");
ioctl(s,SIOCGIFINDEX,&ifr);
printf("can0 can_ifindex = %x\n",ifr.ifr_ifindex);
addr.can_family = AF_CAN;
addr.can_ifindex = ifr.ifr_ifindex;
bind(s,(struct sockaddr*)&addr,sizeof(addr));
frame.can_id = 0x123;
strcpy((char *)frame.data,"hello");
frame.can_dlc = strlen(frame.data);
printf("Send a CAN frame from interface %s\n",ifr.ifr_name);
nbytes = sendto(s,&frame,sizeof(struct can_frame),0,(struct sockaddr*)&addr,sizeof(addr));
return 0;
}
