Android unique id

Question

How do I get an unique id from an android phone?? Whenever i try to get the unique id from the phone as a string it always shows "android id" and no other unique hex values how do i get that one?

This is the code I use to get the id until now:

String id=Settings.Secure.getString(contentResolver,Settings.Secure.ANDROID_ID);
Log.i("Android is is:",id);

the output which i get is like this in my log cat:

Android id is: android id

i am using nexus one for testing.

how can i get that unique hex id?

Answer 1

((TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE)).getDeviceId();

with manifest

<uses-permission android:name='android.permission.READ_PHONE_STATE' />

Here is some interesting reading about the android id:

How to set the Android ID

Android ID Requires Market Login

Try setting it to something other than 'android id' and see if you read the new value.

Answer 2

Wireless MAC address is more unique than IMEI, because the later gets spoofed on stolen devices. Drawback is that it only works on WiFi enabled devices. WifiInfo
