Currently I am integrating GCM 3.0 new registration process for push notification using InstanceID API.
Before that i am using GCM 2.0 register() method for push notifications and for that I have created project on Google developer console and created Server API key for sending push notification to Device
So now as i am migrating to GCM 3.0 by referring this link. while generating configuration file it asks two things:
- Choose existing project or create project
- Package name of application
By providing these two details it will Auto generate new Server API key but i have already created API key before that.
so is there is any need to change from old API key to new API key or stick to old API key?
