duplicate c2dm to the same device and App

[iavian]

1) User installs the app and subscribe for c2dm(registration key)

2) User uninstalls the app.

3) User reinstalls the app and subscribes for c2dm (new registration key)

Now I send c2dm for registration keys for the device+app, resulting in duplicate alters.

How to address this problem? Thanks for your help.

I allow user to register only when
C2DMessaging.getRegistrationId(this) returns null. Would unregister
help ?

i guess it may be.

if you unregistered, the device will be clear in c2dm server.so next time you register with the same device and the same app, c2dm server may send you another device id.
