You can first get the parent of the ImageView and then get whichever child
you want. But, I am not sure if you can get it directly.

I think you are looking for the emulator option -partition-size maybe.
You can simply use your existing virtual device and invoke it like so:

That creates a 1GB partition.

Well, if you were to show 1000s views on the screen, you would obviously
need more memory. Try creating a list view (a dumb one which returns a new
view every-time) and see if the amount of memory is substantial.
Delay is fine, but I cannot think of a situation where someone might have to

You can display a progress bar or even a progress dialog and still stream
the UI. Have you thought about using a ListView instead btw?

Some facts:
All HTC phones up until the Incredible and EVO had the old synaptics
touch screen which did not support discrete touch points. The new

screens.
Motorola Droid, Droid 2 and Droid X all support discrete touch points.

Use Traceview and find where your performance issue lies. "Building

I see. Well, I'm not doing much in the way of computations. The time

She did not suggest you crated the Views themselves in background thread,
