SMS. Everything else remotely practical is some flavor of pull, in terms of who initiates the request for data (the device) and the timing of such requests (polling). > The problem with this method is that > Android currently has no way to cancel the notification that is sent > by the messaging app. That's definitely a limitation. Ideally, SMS messages are handled by an Intent-style system, where messages corresponding to certain formats are handled by apps, and everything else "falls through" to the standard Messaging application and is treated as a message for human eyes. The bigger problem is that not all phone users have all-you-can-message plans, so you can't assume you can send SMSes to the device with impunity. > So what are some other options? Invent a new phone signaling standard, beyond GSM. Or settle for an Internet-based polling system. Eventually, if somebody changes the SMS-handling behavior in the core OS, you might implement a two-tier solution, going with SMS messages to your app for users who request it, and falling back to polling otherwise. > Or do we have > to wait for Google to change their minds and let us clear sms > notifications (with appropriate permissions of course)?

With respect to beefing up the messaging subsystem to support messages-for-apps in additional to regular text messages, that could be addressed by the community, not necessarily Google. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 1.4 Published! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
