I am creating push notifications for my application on Kindle devices
. I am following all the procedure they explained in the documentation, but still getting this error:
SampleADMMessageHandler:onRegistrationError INVALID_SENDER
I had api_key
in assets folder and added jar file as well. I am using my account in Amazon dashboard. I had tested in kindle HD device with latest version. My device also registered with kindle.
What could be the problem?
