I'm not sure if this is what you're after but you could use: Settings.Secure.ANDROID_ID

public class YourActivity extends Activity {
    //...Omitted code
    public String getId() {
        String id = android.provider.Settings.System.getString(super.getContentResolver(), android.provider.Settings.Secure.ANDROID_ID);
        return id;
    }
}

Note that this isn't an IMEI number, if you need this use getDeviceId()

You can do this using the TelephonyManager and the method getDeviceID(). But unfortunately I think for Emulator it will always return null.

Context.getSystemService(Context.TELEPHONY_SERVICE).getDeviceID();

Don't forget to set the permission that is required for that:

Returns the unique device ID, for example, the IMEI for GSM and the MEID or ESN for CDMA phones. Return null if device ID is not available. Requires Permission: READ_PHONE_STATE

If you want a unique ID as a hex String you might also be interested in:

Have you tried Ti.Platform.id ? That returns a value for me in the emulator.
