Settings.Secure.ANDROID_ID not unique on DROID2?

I'm seeing hundreds (877 at last count) of Froyo equipped devices
using our app with the same ANDROID_ID this month. Normally, this ID
is a unique thing but now it isn't.

I'm guessing this is due to a custom ROM with some invalid settings as
the device is a DROID2 and as far as I know, the DROID2 hasn't been
released yet.

Here's the user agent string:

Dalvik/1.2.0 (Linux; U; Android 2.2; DROID2 Build/VZW)

Has anyone else run into this problem yet?

Re: Settings.Secure.ANDROID_ID not unique on DROID2?

Update:

It appears the Droid2 has got a mistake in the OS. All Droid2 devices
have the same ANDROID_ID: 9774d56d682e549c

How in the heck could Motorola and Verizon make such a fatal error?

That's not good.  This is not going to be fun to work around.

That looks like the same ANDROID_ID as here:

Re: Re: Settings.Secure.ANDROID_ID not unique on DROID2?

So what should be used for the new licensing service on this device? Any ideas?

I don't think Verizon has much to do with it. Also, bear in mind that
CTS-type tests are unlikely to uncover this sort of problem, since
they only test one device at a time, AFAIK.

Re: Settings.Secure.ANDROID_ID not unique on DROID2?

More on this bizarre error:

Here are other devices I see (for the month of August only) that have
this probem:

753	DROID2
4	DROIDX
1	European Vogue
2	Full Android on Vogue
90	HTC Desire
15	HTC HD2
1	HTC Vogue FroYo
1	LG-MS690
2	MSM
4	Nexus One
1	boydTouch HD2
2	thunderc

Here are the builds:

117	FRF91
2	MASTER
757	VZW

Looks like this problem is wider than just Motorola, although it could
be the other devices are custom ROM's.

Just to clarify, by "this problem" you mean having the same ANDROID_ID
as others of its model, or having this one magic ANDROID_ID?

If the latter...do you distribute your app outside of the Android Market?

> Looks like this problem is wider than just Motorola, although it could

Custom ROMs would be one possibility -- the ROM mixer might have
grabbed the ANDROID_ID value out of the emulator.

The reason I asked about distribution is that I seem to recall that
ANDROID_ID is somehow tied into Google accounts and the Android
Market. I'm wondering if this magic ANDROID_ID is the new default
value. If so, devices that are not set up with the Android Market
(e.g., emulator) might return this value. That wouldn't explain the
DROID2 -- if 100% of DROID2's aren't getting the Market, that'd be
*huge* -- but it might explain some of your other ones.

So prior to this month, there were no duplicate ANDROID_IDs? With pre-
Froyo devices?

I can't say there were or weren't any duplicates pre-Froyo. I can say
that every Droid2 that has downloaded my app "Radar Now!" has the same
ANDROID_ID.

If you look into the SettingsProvider class, then you can see that
this is done using

SecureRandom random = SecureRandom.getInstance("SHA1PRNG");

When the persistent system property ro.serialno is set, then this
value
will be used to  reseeds this random object.

Later comes a random.nextLong transformed to a Hex-String.

Interessting might be this part of the javadoc:

"the system will determine if there is an implementation of the
algorithm requested available in the environment"

Maybe their is a problem with this SHA1PRNG algorithm ?

Try to set "ro.serialno"  with setprop ..

Good luck !

Re: Settings.Secure.ANDROID_ID not unique on DROID2?

Here are the numbers I've seen for July (ANDROID_ID =

24	DROID2
4	DROIDX
3	European Vogue
11	HTC Desire
1	HTC HD2
4	HTC Vogue FroYo
40	MSM
10	Nexus One

Builds:

29	FRF91
44	MASTER
24	VZW

Seems to be a problem that's mostly with the DROID2.

Yeah, I strongly suspect those others are indeed custom builds,
looking at the devices. What's an MSM?

That's the thing I'm most concerned about as well, at this point. I'd
REALLY like to hear from Mountain View on that topic. Trevor, you

Hi everyone,
I've been trying to investigate this on my end, but unfortunately I
seem to having some trouble finding a Droid 2 in the office to
actually reproduce this with.

If anybody has access to a device that's exhibiting this behavior,
would you please send me a copy of the build fingerprint?

Thanks!

I have to say, though, that if there's one company that I would have

Google...

As far as I can tell, every DROID2 has the same ANDROID_ID. It's not

Re: Settings.Secure.ANDROID_ID not unique on DROID2?

Great. I can just wait to see if angry customers ask why their trial
is already over.

Nonetheless, I couldn't find 9774d56d682e549c among my trial users.
Maybe no Droid 2s have tried it yet.

I'm using this as the id but I believe it does the same as ANDROID_ID.

		TelephonyManager manager =
(TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);

		String imei = manager.getDeviceId();

I haven't seen that number yet. I'm still waiting for angry users

This is the code I use, but I think it returns the same as ANDROID_ID

		TelephonyManager manager =
(TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
