I am confused. According to above, "There is no Bluetooth API in the
SDK at this time", yet Android does offer:
"Stereo Bluetooth support (A2DP and AVCRP profiles) " (http://

Is there no API for use with the A2DP or AVCRP profiles?

I tried implementing OnSharedPreferenceChangeListener as well (1.5_r2)
and could not get it to work. Since I never had working code in a
prior Android version, this could be due to a mistake in my coding.
However, I just switched to using onPreferenceChangeListener() and it
worked fine...

O
1) invert the preference "question" for the dependency.
2) If you convert your preference from XML to code, you may have more
flexibility.
(You have probably considered both and neither is a good option for
you...)

You probably have thought of this, but when you created the AVD did
you enable camera support (the default is disabled)?

Thank you for the info.
I have noticed that the "leaked window" error is largely fixed with
1.5_r1 if you run using a 1.5 AVD. (It still occurs when I initiate a
preference from an intent inside an xml, but is otherwise "cured.)

This invokes an Intent directly from Preferences XML which is handy.

The fling animation is automatic with the Gallery class. If you need
your own (new) widget class, just
make your own MyGallery class which extends Gallery.
Then just overwrite the onFling() method to do whatever you want to
do, and at the end of that method call super.onFling(args).

I have written a custom class MyGallery which extends Gallery.
This enables me to override the onScroll() method of Gallery.
Now that I have done this, I have found that onScroll() behaves oddly.
When I scroll on the emulator, it activates the onScroll() method
multiple times - usually 2-4, somet

I am not sure why you are getting onItemSelected() activated more than
once.
I don't, and my code is slightly different. First, the onItemSelected

My limited experience has been that Android does automatically
compress and stretch at runtime.
If you want to keep the proportions, you need to specify:
android:adjustViewBounds="true" in XML formatting, or equivalent in
Java.
