In a certain situation, I'd like my app to be able to "fake" an incoming SMS on the user's device, as a sort of notification. This would save me money when I'd normally use Twilio to send a text to my users but I know they already have my app. Is there any way to do this? I imagine it would have something to do with Intents and Content Providers but I don't really know where to start.
To clarify: I'm not new to Android and I do respect all of the normal Notification methods. However, my app will have an opt-in for text messages and I'd like to be able to trigger them for free rather than paying for it. This is for SMS-specific uses and not as a substitute for a normal Notification.
