Unique ID of Android device

Question

I want some unique ID of the Android device. I've tried it with the following code

String ts = Context.TELEPHONY_SERVICE;
TelephonyManager telephonyManager = (TelephonyManager) this.getSystemService(ts);

However I know that this works only for phones.

What if my app is running on some notebook, netbook or other type of device? How do I get an unique ID in that case?

Answer 1

There are three types of identifier on android phone.

1. IMEI

2. IMSI

   String ts = Context.TELEPHONY_SERVICE;
   TelephonyManager mTelephonyMgr = (TelephonyManager) getSystemService(ts);
   String imsi = mTelephonyMgr.getSubscriberId();
   String imei = mTelephonyMgr.getDeviceId();
   

3. Android ID It is a 64-bit hex string which is generated on the device's first boot. Generally it won't be changed unless is factory reset.

   Secure.getString(getContentResolver(), Secure.ANDROID_ID);
