GCM returns "Unavailable"

[sparkgene]

I'm working on migrate to gcm.

Using gcm.jar to get the registration id is successfully done.

Sending the message to gcm endpoint returns HTTP Status 200.

But the result contains error => Unavailable.

In the GCM document(http://developer.android.com/guide/google/gcm/gcm.html) this error solution is "If it is Unavailable, you could retry to send it in another request."

Do anyone have information about this error?

[Monnand]

I have exactly the same issue.

No matter how many time I tried, it keep receiving "unavailable" error.

Have you had any solution on that now?

Did you get it just once or did you get it again when you retried?

Usually, you get an 'Unavailable' when the server could not process one message in the multicast, in which case you should try again. But if you're always getting that error, it might be caused by something else that we would have to investigate.

Notice that if you use the Sender class from the gcm-server.jar, it has logic to automatically retry.

Hi Felipe,

I got it every time I retried. I am using my own code. Is it possible that I got unavailable error because of the error on my side? (According to documents, it should not be possible.)

Here is the result I received:

{"multicast_id":5030400576422639801,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"Unavailable"}]}

Thank you!

Your code should be fine, but there might be something wrong on our side that we need to investigate.

What's your package name? (you can answer me in private, if you prefer)

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.

[Monnand]

Oops. I forgot to remove my registration ID. Anyway, it just a test device with nothing valuable data. Please ignore it.

Sorry about that.

Monnand,

we do set the value to 4 weeks if the number is bigger than that,
however if the number is too big (you can write all the digits you
like) than we do invalidate the request.

We definitely need to return a better error code for this case and we
are already working on it. We will also update the documentation
accordingly.

Thanks for pointing this out,
f

Hi Francesco,

Thanks for your reply. I can see all you guys are working hard on this project. Really appreciated.

As you mentioned, it might be better to return another error code on this situation. I think I was lost in this document before.

Regards.

Thanks for the reply.

I think the problem is resolved in this.

I have used cURL php

Here is my code:

 

        $json['data'] = $data;

        $json['registration_ids'] = array($registrationId);

        $json['collapse_key'] = $collapseKey;

        $json['delay_while_idle'] = false;

        $json['time_to_live'] = 100;

        

        $headers = array(

            'Content-Type:application/json',

            'Authorization:key=' . GOOGLE_API_KEY

        );

        

        $curl = curl_init();

        curl_setopt($curl, CURLOPT_URL, $gcmUrl);

        curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);

        curl_setopt($curl, CURLOPT_POST, TRUE);

        curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);

        curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($json));

        $response = curl_exec($curl);

        curl_close($curl);

Result: 

{"multicast_id":6086117185750372243,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"Unavailable"}]}

Thank for reply!

I resolved this, obviously you also receive 'Unavailable' if an app hasn't registered with a senderid yet.

Woot, a working python gcm sender :-)

After making the encoded json data somewhat closer to the sample on http://developer.android.com/guide/google/gcm/adv.html :

{"delay_while_idle": true, "collapse_key": "Event", "time_to_live": 86400, "registration_ids": ["<mykey>"], "data": {"message": "Testing"}}

I'm still getting 'Unavailable' ... any news on this issue? :)

Hi JonathanC!

Im trying to make this work but I always receive the "200 + ´Unavailable´" message 

I read this and I want to know what do you mean when you mention "if an app hasn't registered with a senderid yet."?

regards

Christian

[Thao Phi Dinh]

Thank's !

I trying.
