I had some problems with setting background too, namelly in an
Activity !
The background image is always stretched or compressed in order to fit
the window.
Besides not having any options, for tiling, stretching, etc. the real
problem is that this is always done in every redraw.
What I mean is,
Maybe its just converting them to the default screen format of
RGB_565, so that no processing is done later when running the
aplication.
Just a will guess !

Just guessing here, but several stuff to verify.
- you probably should set the Filter flag, after adding a MaskFilter,
and not before.

- Are your shure that your originalBitmap has a Alpha channel ?
Verify!

Many phones can be using the same cell !
Your phone only uses one cell at once, but can negotiate data with
more than one, when doing transfer from one cell to the other.

Dear fellow developers
These have been some hard debugging months (3 for me).
I have send my submission, and received the confirmation, so
everything is well, now I can get back to my family, and rest at night

i.e. can we set the bounds of a drawable larger than it's associated

setBounds

When using BitmapShader, the results might be surprising, or look
strange or just erroneous.
This looks like a bug or problem, because the class/methods
documentation is missing some important info.
Nowhere in the documentation is stated that the bitmap will be pinned
down to the screen absolut

Do you really need to use that syncrhonized(lock) ?
Doest it work fine without it ?
If no one else is messing with the progressDialog, why would you need
to lock it ?
There shouldn't be any concurrency issues.

Once again thank you for the feedback.
I would then suggest for someone to review the examples, since I'm 99%
sure that I got the Application suggestion, from an Android
Documentation example, I just can't pin point it right now.
Currently, it's working a lot better and faster, by using
androidManifest.xml. I only declare my Activities there and that's it.

You are doing something really strange!
First you setup a bitmao as your canvas

But later, you use your canvas ( which uses your bitmap as it's
buffer) and you draw on it, using

decouple the several application parts, but the current API, is not
very helpful, in making the common message usage simple.
Any help on this would be great too.
