I would like to know what is returned in android in the TelephonyManager class when I call the getDeviceId method, the device has no chip. I need an identifier for the device and I thought about using the IMEI, but I do not have a device without CHIP to test the feedback of this information. Here is the code below.
TelephonyManager tManager = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
String uid = tManager.getDeviceId(); //Serial do dispositivo android
