I have written the following code to receive SMS messages from a phone using the
Telephony APIs, and it all appears to work except for one step: TelSmsSelectStorage
never changes the storage from store 0 (the SIM card). No matter what I do it never
changes. I have written the code synchoronously (as seen here), asynchronously, trying
different values for the storage, still nothing.
The Palm France team, who wrote the Telephony APIs, haven't been able to help me out
with this so I am really hoping that someone here will know something about what I
need to do to retrieve messages from all available stores.
Any help would be greatly appreciated.
Thanks,
trv
PS: I stripped out all the code pertaining to my app specifically, like the storing of
the messages in my database, etc.
