android - Reliability of C2DM -

i having issues c2dm. works perfectly, messages not pushed. is there reliable way enforce connection? pull messages. read somewhere google maintain low bandwidth tcp connection server @ time. assume when switching between network types tcp connection falls downwards , android tries reestablish connection c2dm servers. might fail on wifi restricted network. is wrong assumption?

i have noticed whatsapp on wifi not messages. when switch 3g them @ moment of switch. what tips experience c2dm offer?

c2dm not suitable critical parts of application, since google not offer sla or paid tiers guarantee reliable service , throughput.

i've considered several alternatives myself: xmpp via asmack, parse, deacon, urban airship, , mqtt.

after reading , experimenting decided go mqtt. lightweight telemetry protocol invented @ ibm fits quite nicely in android force notifications scenario. recommend give try, here's nice blog post guide you: using mqtt in android mobile applications.

hope helps.
