[This library](https://github.com/delight-im/Android-BaseLib) provides a unique ID per device with [Identity.getDeviceId(context)](https://github.com/delight-im/Android-BaseLib/blob/master/Source/src/im/delight/android/baselib/Identity.java) and an identifier for your app installation via [Identity.getInstallationId(context)](https://github.com/delight-im/Android-BaseLib/blob/master/Source/src/im/delight/android/baselib/Identity.java). — caw, Mar 08 '15 at 22:38

Try this :

    String deviceId = Secure.getString(this.getContentResolver(),
            Secure.ANDROID_ID);
    Toast.makeText(this, deviceId, Toast.LENGTH_SHORT).show();

android.provider.Settings.Secure.ANDROID_ID

A 64-bit number (as a hex string) that is randomly generated on the device’s first boot and should remain constant for the lifetime of the device.

Note : The value may change if a factory reset is performed on the device.

This is not exact. This ID might change upon rooting phone, and also upon doing a "factory reset". So, this could be used - but do not count on it. – gilonm Jun 17 '14 at 11:48

@user3736827 : There is no specific deviceId concept, you need to check the unique string that identifies your phone like the one mentioned in the answer or you can use IMEI number. – Siddharth_Vyas Jun 17 '14 at 11:53
@Siddharth Oh, just saw this link now.. I simply had this problem a couple weeks ago... – gilonm Jun 17 '14 at 11:54
@gilonm : I have also edited my answer and added a note on that point. – Siddharth_Vyas Jun 17 '14 at 11:54
@Siddharth I saw that.. Cheers! – gilonm Jun 17 '14 at 11:55
will this ID change upon OS update? – Hendra Anggrian Mar 13 '17 at 11:36
@HendraAnggrian : Yes – Siddharth_Vyas Mar 14 '17 at 04:50

Try this:

TelephonyManager TM = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

// IMEI No.
String imeiNo = TM.getDeviceId();

// IMSI No.
String imsiNo = TM.getSubscriberId();

// SIM Serial No.
String simSerialNo  = TM.getSimSerialNumber();

// Android Unique ID
String androidId = Settings.Secure.getString(this.getContentResolver(),Settings.Secure.ANDROID_ID);

Don't forget to add

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

to your manifest file.

hello sir I am confused by answer....I just want to check unique ID of my htc phone....but how could i do this...everybody give me link and code to check id......but i dont know how to implement this...please tell me in brief – user3736827 Jun 17 '14 at 12:04
Hi, the thing is, a "unique ID" could mean many different things depending on the context and on your specific situation. The [official Android blog](http://android-developers.blogspot.in/2011/03/identifying-app-installations.html) recommends that you use the ANDROID_ID, which is the fourth option above in my code and which is supposedly the least risk-prone option. Just keep in mind that the ANDROID_ID is reset each time the user performs a factory-reset, so you may want to take this into consideration for how it may impact your app. – Yash Sampat Jun 17 '14 at 12:09
doesn't work, error 'ANDROID_ID cannot be resolved or is not a field' – Shirish Herwade Mar 18 '15 at 16:00

@ZygoteInit yes I would like to do that if my problem gets solved; but the issue is i'm using this device no to download apk using chrome extension, but its giving error... and i'm not able to download apk, so my problem still not fixed. By the way, thanks for your time and help. and so I have upvote the answer already. But hey... its not my question so can't accept – Shirish Herwade Mar 19 '15 at 10:37
@Y.S , Please help me on it, I want to get the ID of the device, which even not changed when device is rooted or wiped out. What could be possible solution of it? – Ravindra Kushwaha Oct 21 '20 at 07:55
I would like to, when you're using "READ_PHONE_STATE" permission make sure to ask this permission to user at runtime as this permission is categorized as "Dangerous permission" in official doc. – syed dastagir Jan 27 '21 at 08:02
