I'm really frustrated at this point. Not because I don't know what I'm doing but because I can't find any reliable info on what's needed to get this working.
Here is rundown on what I did up to this moment:
I was logged in to my google account when I did that and I used other email attached to this same account(alias on my google apps for business). Registration didn't work for 2 days (I saw posts on this) - but finaly it got through.
2. Implemented C2DM on Android side. This is easiest part. Device get's Registration_id and I don't see why it wouldn't get messages...
4. Documentation stated I need Client Login to login. Login WHERE? With WHAT UN/PW?
5. Links from c2dm page broken. Finally search for Client Login - deprecated. Nice. Should I use OAuth2? How do I know? c2dm documentation silent.
9. Using API to send:
https://android.apis.google.com/c2dm/send Good registration Id, Good Auth token from #8 - 401 from Google. Actually, no. First it failed - SSL is bad on this server. Then I killed SSL check in my code and now it's 401
10. How do I suppose to figure out? No contact info on developers site.
11. Emailed Google Play developers support
12. Found this forum - seems to be alive. Posted. Hopefully Google employees monitor it.
Really frustrated! Google need to do better job documenting what needs to be done!
