It was correct.

ls -l /dev/binder, do you have? What are the permission? According to
the code
static int
open_driver()
{
if (gSingleProcess) {
return -1;
}
int fd = open("/dev/binder", O_RDWR);
if (fd >= 0) {
[...]
} else {
LOGW("Opening '/dev/binder' failed: %s\n", strerror(errno));
}
....
It fails if it can't open the device. So maybe the device don't exists
or you don't have
permission over the device. You can find the code here
frameworks/base/libs/utils/ProcessState.cpp. The binder is import for
process communication,
android don't use the standard unix IPC channel.
