 Hi,
   I've just found out that _ID field is not always unique in SMS table and
gets repeated after some days. Is it normal or some bug ? Can someone tell
what is threshold before _ID field is repeated. Actually i have implementing
a logic thinking that _ID field is always unique in all records i.e SMS,
Call logs, Contacts etc but now discovered that it is not guaranteed to be
always unique in SMS messages. I didn't check for contacts , call logs etc
but it is true for SMS messages.

Suppose a SMS messages had _ID field equal to 1. But after some days that
message is deleted so now 1 is not assigned to any message as id, will the
system assign that id to some new message whenever it wants to ?

Regards,
shaz

I have been reading through various discussions and it seems like real-
time audio processing on Android has some minimum latency. I am about
to develop an app that is as simple as recording and playing back
simultaneously. My question is it possible to do it on an Android
platform. I have Nexus One for the testing. Any clues as to if it will
be possible with a latency of say 10ms?
