 Dear all,
I find that geocoder apis particularly getFromLocation using Lat and Lnt is
not very reliable. I am noticing this behavior more after I upgraded to
android 2.2 on my Droid. I get an invalid argument exception for Latitude.
The funny thing it is not consistent in this behavior. It works some times
without any problem.

any tips?

Base on posts I've seen, I think people employ workarounds like wrapping the
call in a try catch and trying to get a valid value 3 or so times, waiting a
second or so between each attempt, to try to get a good value before giving
up and reporting an error.

 yes, it is in a try and catch and i run it within a while loop to retry if
it fails. I also log the exception caught when it fails. its just not
consistent. Is there a known issue with geocoder ?

API, i only read about problems online and it just won't work here... Sigh.

I've had this problem in a few different apps now and I can't seem to
find a solution.

If, in the onCreate() of an Activity, I start a new activity that uses
the dialog theme (via android:theme="@android:style/Theme.Dialog" in
the manifest) it doesn't draw anything to screen... the whole screen

I need to display an interactive (scroll, zoom) panorama out of a qtvr

Before I try and port this code :

- may I encounter performances problems doing image computation in
pure Java when scrolling, etc..?
