android - Sending a notification-only payload to GCM using AWS SNS -

-

i trying send mobile push notifications gcm via aws sns. according latest gcm 3.0 documentation, 1 may include either "notification" payload or "data" payload (or both). if send notification payload, gcm take care of showing notification on end-user device you.

using amazon sns console, tried sending notification-only payload, encountered following error:

invalid parameter: message reason: invalid notification protocol gcm: data key expected in json message (service: amazonsns; status code: 400; error code: invalidparameter)

i'm sending:

{   "gcm":"{\"notification\":{\"title\":\"test message\"}}" }

i suspect might issue sns still conforming previous version of gcm , therefore expects "data" key, i'm not sure. else having similar problem or have experience this? thanks!

edit: clarify, want send gcm notification payload , have display alert user automatically described in documentation. right now, i'm beginning wonder if sns forwarding notification payload device.

to answer own question, received following aws support on forums:

you correct, sns not support gcm's "notification" payload type described in documentation. sns supports initial "data" payload type actively working on solution support "notification" type. in meantime, "data" payload works same except client app responsible processing data messages has in past.

so until sns supports gcm notification payload, have handle display of notifications extending class gcmlistenerservice , overriding method onmessagereceived.

update 10/2015: seems sns has implemented support gcm notification payload. if include both "data" , "notification" payloads, "notification" take precedence. observed behavior on sns, not find aws blog/articles announcing this.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
