To enable density compatibility mode you would expect to find:
|anyDensity="false"
in the ||<supports-screens> section of the manifest?
My manifest has this:
<supports-screens android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:anyDensity="true" />

Have you made sure you are not running in screen density compatibility

I can get the size of the wallpaper from the wallpaper manager:
m_context = app.getApplicationContext();
WallpaperManager wpMngr =
WallpaperManager.getInstance( m_context );
m_intWPheight = wpMngr.getDesiredMinimumHeight();
m_intWPwidth = wpMngr.getDesiredMinimumWidth();
I can then get the size of the display area:
Display display =
app.getWindowManager().getDefaultDisplay();
m_intScrWidth = display.getWidth();
m_intScrHeight = display.getHeight();
I have my image that I want to rescale:
m_bmpImage = BitmapFactory.decodeResource( m_res,
intResId );
m_intImgWidth = m_bmpImage.getWidth();
m_intImgHeight = m_bmpImage.getHeight();
Scaling from the Image height to the display height:
m_fltSFbyHeight = (float)m_intScrHeight /
(float)m_intImgHeight;
What I want to do is create a black bitmap that is the same size
as the wallpaper ( intWPwidth, m_intWPheight ), then copy/blit
into this bitmap the bitmap to use as the wallpaper re-scaling it
to fit if required, so I end up with a bitmap image the same size
as the wallpaper with the image centered and scaled in the middle
of it.
Thank you.

Sorry, I should have included the code to resize, once I
calculate the new width and height I call:
return Bitmap.createScaledBitmap(m_bmpImage,
m_intFinalWidth,
m_intFinalHeight,
false);

When using the code on Android 1.6 platforms, the bitmaps are
re-sized as aspected, however when used on Android 2.1 its as
if the function to rescale has no effect what so ever, the
wallpapers always come out the wrong size.

On Android 1.6 my wallpaper applications resize the
wallpapers correctly, however on Android 2.1 the resizing
doesn't work, its the same on the emulator.
I've tried using both the Matrix and
Bitmap.createScaledBitmap both do exactly the same and
work find on 1.6. Can anyone explain what is happing and
why these routines don't work on Android 2.1?
I start off by getting the device screen size using:
Display display = app.getWindowManager().
getDefaultDisplay();
m_intScrWidth = display.getWidth();
m_intScrHeight = display.getHeight();
I load the image from a resource with:
m_bmpImage = BitmapFactory.decodeResource(
m_res, intResId );
m_intImgWidth = m_bmpImage.getWidth();
m_intImgHeight = m_bmpImage.getHeight();
m_fltSFbyHeight = (float)m_intScrHeight /
(float)m_intImgWidth;
Then to scale the image:
m_intFinalWidth = (int)((float)m_intImgWidth *
m_fltSFbyHeight);
m_intFinalHeight = (int)((float)m_intImgHeight *
m_fltSFbyHeight);
Thank you,
Simon
