Android GCM send and MismatchSenderId

Question

The odd thing is that notifications were working before. So I\'m not sure what happened. I tried reinstalling my app to the device, but nothing changed.

Answer 1

curl -X POST \
-H "Authorization: key= write here api_key" \
-H "Content-Type: application/json" \
-d '{"registration_ids": ["write here reg_id generated by gcm"],
"data": { "message": "Manual push notification from Rajkumar"}, "priority": "high" }' \ https://android.googleapis.com/gcm/send

MismatchSenderId because with in same device you have logged with different keys. to solve this problem uninstall app and run it againg and update the registration key. and then run the CURL script in your teminal which i post above it will give success message and you will get notification to your device
