onSizeChanged, which gives the size of the view, is one thing.
But you keep saying *screen* dimensions, which is quite another.
If that's what you need, you can use DisplayMetrics:

Check out widthPixels and heightPixels, which give screen size.

Hmm, no way? Even if I have android:screenOrientation="landscape" in
my manifest ? This way screen dimensions will ( am I right? ) never
change, and should be accessible anytime...
Currently I initialize part of my View in its constructor, than I have
to do all kinds of locks to somehow survive without a crash until I
get the onSizeChanged() message and can initialize the rest (which
depends on screen size ) and then I have to ignore subsequent
onSizeChanges() which, for some reason, still sometimes come ( even
though, of course, neither the physical screen size nor orientation
has actually changed ). For example, if I have my app on top, and
screen saver kicks in, and I awake the screen, then my app gets shown
again and gets ( in my opinion, spurious ) onSizeChanged() message
which needs to be ignored.
Doing the above is feasible, but messy. It would be way more
convenient if I could simply figure out the screen dimensions in
View's constructor, construct everything and do not bother with
onSizeChanged ( like I do in versions of said app for Symbian and
Blackberry )

Sorry, there is nothing earlier, that is the point where this has been
figured out.

Hello Android gurus,
I am aware that when screen dimensions change, I get a call to
onScreenChanged() and there I can figure out its dimensions, however
it would be much more convenient if I could figure this out earlier,
namely in my View's constructor.
Any tips?
