google cloud messaging - Android GCM SENDER_ID, how to get it? -

-

i try migrate gcm , have issue sender_id need provide. use demo project google. in project need, if understand well, provide sender_id application in commonutilities.java file.

the sender_id provided api key registered on https://code.google.com/apis/console/ , has form: aizasyaxxxxxxx_xxxxxxxxxxxnogzw (total 40 chars).

using string sender_id on "broadcastreceiver mhandlemessagereceiver" error message: from gcm: error (invalid_sender)..

where mistake? string provide not sender_id?

thank you.

no, sender_id project id signed @ google api console, should numeric string. e.g. on browser uri, should see this: 

https://code.google.com/apis/console/#project:4815162342

the sender id 4815162342

updated answer:

google has not updated docs completely. above answer old , based on documentation , seems still not updated.

according updated google docs, seems project number on google api console used sender id

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
