Been going slightly mad over the last two days trying to get Android push notifications to work, with zero success. Devices get registered with gcm, but no devices show in the control panel and not able to send pushes. Very frustrating as other people appear to be having no problems.. Finally found that the string builder in BT_gcmServerUtils.java doesn't appear to be dealing with white spaces. I was testing on two devices - HTC One X and HTC Wildfire. The strings are breaking on the first white space in the deviceModel parameter, eg: HTC space One space X Just tested on a device with no white spaces in the device/model name (acer-G100W) and everything work fine.

Very interesting! Might explain some behaviour I've seen as well. I've alerted @David this thread. Mark

Thanks Mark. I did send David an email a while ago, but I guess it's pretty early in the morning over there?

It all depends how long he stayed up the night before! ;-)

lol! quite late I expect!

I have a htc one v same issue, before I seen this thread google showed htc's doing this with a lot of push services. Now I know its not just me.

Ok...getting back to this. 1) Open BT_gcmServerUtils.java 2) Find the gcmServerPOST method starting on line 139. 3) Add this on line 148: //encode URL... serverURL = URLEncoder.encode(serverURL,"UTF-8"); Just above this line: HttpClient httpclient = new DefaultHttpClient(); 4) Compile, see if the Exception goes away. The issue is an "illegal character" in the URL, as you already realize. The built in Java URLEncoder class seems to have fixed it on several tests on this end. If it fixes it for you, we'll update the gcmServerUtils.java file for future downloads

Nothing changed, device says registered doesnt show.

@Arubaman - If you're only working with Android there's a temporary workaround. Go to the core settings in your control panel, go to the push notification settings and in the register url remove: &deviceModel=[deviceModel]

Thanks...Unfortunately working with both, not in a big hurry-app I'm working on is just a update.

Gave this a try, got this: Description Resource Path Location Type URLEncoder cannot be resolved BT_gcmServerUtils.java /OVFPSv2/src/com/ovfpsv2 line 149 Java Problem Mark
