How can I get the UUID of my Android phone in an application?

Question

I'm looking for help to get the UUID of my Android phone. I have searched the net and found one potential solution but it is not working in the emulator.

Here is the code:

Class<?> c;
try {
    c = Class.forName("android.os.SystemProperties");
    Method get = c.getMethod("get", String.class);
    serial = (String) get.invoke(c, "ro.serialno");
    Log.d("ANDROID UUID",serial);
} catch (Exception e) {
    e.printStackTrace();
}

Does anybody know why it isn't working, or have a better solution?

This works for me:

TelephonyManager tManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String uuid = tManager.getDeviceId();

EDIT :

You also need android.permission.READ_PHONE_STATE set in your Manifest. Since Android M, you need to ask this permission at runtime.
