I have a great number of tablets (60-50) and I would like to assign each of them a number in order to maintain them, but what is the best method to do this? I have thought of: 1. Using Bluetooth adapter and changing the bluetooth name for each Tablet (01, 02, 03)... However some tablets don't have this option and I can´t change the Bluetooth name. 2. Putting a XML file with the Tablet number in each Tablet and parse it to identify the Tablet. 3. Using an option lile Build.Serial in Android to get the Android ID. However I would like to know if there is another option which does not return the Android Id, which is so long.
Are there any options available, and which is the best option?
Thank you
