void *exec = mmap(NULL, (size_t) getpagesize(), PROT_EXEC | PROT_READ | PROT_WRITE , MAP_ANONYMOUS | MAP_SHARED, -1, (off_t) 0);

memcpy(exec, code, sizeof(code) + 1);

asmcheck = (FunType) exec;

asmcheck();

__asm __volatile (

"mov %0,r0 \n"

:"=r"(a)

);

munmap(exec, getpagesize());

return a;

}

JNIEXPORT jint JNICALL Java_com_android_util_SimulatorChecker_check

(JNIEnv *env, jobject object) {

int isSim = detect();

return (jint)isSim;

}

只有当 check 方法返回是 10, 判断设备为真机, 否则为模拟器.
