I think it would be better to cc to android-gcm group. I have already 
corrected the code --- It seems like a bug on GCM side.

Here is the message I sent causing "unavailable error"
{"registration_ids":["SOME REG 
ID"],"collapse_key":"c058391ee54cec4b8812ab121411afbaf6de024a","data":{"msg":"Hello 
World"},"delay_while_idle":false,"time_to_live":4294967295}

Here is the message I sent without problem:
{"registration_ids":["SOME REG ID"],"data":{"msg":"Hello World"}}

Then I thought it might be the value of time_to_live field is too large. So 
I tried this:

{"registration_ids":["APA91bHaWwM9ytxfHVBjHZTtQ7Ggw_rovTOYFMzhi5ae-gLySoejokMpBx9krhynlYj_9kG2d3rg7C5carlybQcfIiIlIho4MR1AjWJIhk45SJ4mMFWP038KUP5THTZtVsuAPicio54IRqjSMgCNy9TgOdZAL_toow"],"collapse_key":"67ab7e1dae275e389c9fbc323b68a2b568962294","data":{"msg":"Hello 
World"},"time_to_live":4294967295}

And I got unavailable; but the following data could be sent.

 {"registration_ids":["APA91bHaWwM9ytxfHVBjHZTtQ7Ggw_rovTOYFMzhi5ae-gLySoejokMpBx9krhynlYj_9kG2d3rg7C5carlybQcfIiIlIho4MR1AjWJIhk45SJ4mMFWP038KUP5THTZtVsuAPicio54IRqjSMgCNy9TgOdZAL_toow"],"collapse_key":"1c2ded740aca18f2148fec0a78e9a1a57526440e","data":{"msg":"Hello 
World"},"time_to_live":120}

Would you please check if I am correct? It might be better if set 
time_to_live to the default value if the value in the request is too large.

Regards,
-Monnand
