I am developing a dynamic library for Android devices by JNI. And I have to get the UUID of the device without using of the Android APIs. I have tried to get the CPU Serial Number or MAC Address via Shell Scrip. such as:
cat /proc/cpuinfo
cat /sys/class/net/wlan0/address
But the Serial Number is always 0000000000000, And there is no wlan0 folder in my phone. Now I am so lost, can anybody give me some tips!
