When I fire up the same code on an actual device (Droid 2.0.1), all I get are white squares. This suggests to me that the textures aren't loading, but I can't figure out why they aren't loading. All of my textur...
I created a simple Animation-derived class and added an onclick listener to a view (a LinearLayout in this example, just to make a quick proof-of-concept) that called startAnimation on the object (passing it an instance of my class).

We are utilizing the Intent.ACTION_IMAGE_CAPTURE for taking a new picture from within our app. However, we would like to force geo-tagging of the pictures.
