android - GCM notification results=[error=NotRegistered] -

-

i using node gcm.

the notifications working fine in devices of customer. phones have issue not notifications after time period.

after checking logs saw below error in calls.

{"multicast_id":7040074623564131000,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"notregistered"}]

i not canonical_ids 1 or above, response or on responses before it.

i followed steps mentioned in canonical registration id , message id format , did not canonical ids in response.

in phones, gcm works fine i'm not sure how proceed here , debug.

notregistered - message, say, there no gcm device registered passed id. check id.

you must send push notifications on devices, registered in gcm , in app (via developer console).

you can test different rest clients postman. send data on special url using json.

there java program read files folder, processing , write output files in folder. ran 4 hours , produced few files failed after throwing following error: "too many files" then modified program close (bufferreader , bufferwriter) , started process again. time process failed after starting throwing following error: java.io.filenotfoundexception: <file> (too many open files) then tried running lsof , searched process having no of open files. realized networkmanager. not sure whether should kill process or not. restarted machine. after when ran java program, still got same error. in worst case might possible code still having leaks in terms of not closing everything, still failing after starting process. have feeling lying in system previous run. if start same process in other machine, runs hours before failing. you cannot retain resource between runs of program, if wanted to. leave system without enough resources in theory, though unlikely, restarting...
