android - Get GCM Registration ID directly from server -


while publishing android app, created blunder. commented code used fetch gcm registration id , send our server persistence. have device id of users, however, gcm registration id missing on our server side. there way, can register users , gcm registration id server directly using respective device id?

also, if gives me correct solution, beer treat assured!

in short no. gcm instanceid token identifies app on device, more device's id needed generate token. google play services on client device used generate application's instanceid token. token cannot generated device id.

each app on device should have unique instanceid token, being able generate externally device known parameters security issue.
