Google Cloud Messaging with CCS and XMPP

A talk about the new features in Google Cloud Messaging

Transcript

1. Google Cloud Messaging Cloud Connection Server and XMPP
2. Google Play Services • This meeting is about Android 4.4 • But this talk is not :-) • Google Play Services is all that's needed
3. CCS • Upstream messaging possible • Permanent connection between servers – But Google keeps messages around a while • XMPP instead of HTTP • You cannot use it right away – You have to sign up for it
4. Flow of Events
5. Android Code
6. Sample Message I
7. Sample Message II
8. Benefits • Reuses Connection – Battery friendly • More messages in a shorter timeframe • Android Client easier to develop – You need not care about queuing – No need to check for network availability • Notification cancellation
9. Drawbacks • XMPP is less known than HTTP • Less information online about XMPP • I have found only one maintained Java lib • Less information online about CCS • Manual ACK / NACK handling • Proxy servers can be an issue • No Cloud Services support (as of yet) – Not even Google App Engine!
10. Recommendation • It's beta, so stay calm :-) • Ideal for sending out many messages • To a very large user base • And for many return messages from device • Do not trust the emulator!
11. What else • Github links: https://github.com/writtmeyer/gcm_sample https://github.com/writtmeyer/gcm_server • Blog post in the next days on grokkingandroid.com • A big thank you to Dennis Geurts!
