I get the same error on my Motorola Droid.  I used pdanet to install the ADB 
driver
and verified it was the most recent driver by trying to update using the SDK 
USB drivers.

Same error on my Droid, happens on Windows or Linux version of the SDK using 
Java 1.6 
JRE latest version.

I haven't looked at the code at all, but is the buffer that its reading the 
image into, large enough for the extra 
resolution of the Droid?

I'd love to donate to this initiative, but please address this issue. Now that 
droid
has been rooted, a lot of people would want this app to be run with the droid. 
Is
there anyway we (droid owners) can help you in investigating as to what could 
be the
issue?

Newest release eliminates this error.   Droid comes up but screen resolution 
appears 
jumbled and can not see screen effectively.   You can see when changes are 
occuring, 
but cannot make out what screen says

Confirming the behavior tjcsmith mentioned. Attached a screen shot as well.

If the rawImage is passed to display, then the following changes to the source 
will 
work:

1.  Set the BufferedImage to use a type of TYPE_INT_ARGB
2.  Replace the RGB loop you have with the below (borrowed from droidEx code)

                int index = 0;
        int indexInc = rawImage.bpp >> 3;

        for (int y = 0; y < rawImage.height; y++) {
            for (int x = 0; x < rawImage.width; x++, index += indexInc) {
                int value = rawImage.getARGB(index);
                image.setRGB(x, y, value);
            }
        }


3.  This now displays properly on a Droid.  However mouse/keyboard input not 
quite 
working

Is it working for you tjcsSmith? What shall i do to atleast see the proper 
image. I
am a nooB with Android development so don't know what needs to be done with the 
code
you have provided. 

I feel good about the fact that there is no error anymore. At least it's some 
progress.
Thanks

My comments were to the developer.  I'm not comfortable submitting the code 
changes 
since I only have one device to test on.

But the code changes are within:
net.srcz.androidscreencast.api.injector.ScreenCaptureThread.java

In the function fetchImage, there is a call:
 display(rawImage.data,rwidth,rheight);
which I changed to:
 display(rawImage.data,rwidth,rheight,rawImage);

Then in that same component, there is a function:
 public void display(byte[] buffer, int width, int height) {
which I changed to:
 public void display(byte[] buffer, int width, int height,RawImage rawImage) {

Then within that function I replaced the code:
        int index = 0;
        for (int y = 0; y < height; y++) {
            for (int x = 0; x < width; x++) {
                int value = buffer[index++] & 0xff;
                value |= buffer[index++] << 8 & 0xff00;
                int r = (value >> 11 & 0x1f) << 3;
                int g = (value >> 5 & 0x3f) << 2;
                int b = (value & 0x1f) << 3;

                value = 0xFF << 24 | r << 16 | g << 8 | b;
                if (landscape)
                    image.setRGB(y, width - x - 1, value);
                else
                    image.setRGB(x, y, value);
            }
        }

with:

        int index = 0;
        int indexInc = rawImage.bpp >> 3;

        for (int y = 0; y < rawImage.height; y++) {
            for (int x = 0; x < rawImage.width; x++, index += indexInc) {
                int value = rawImage.getARGB(index);
                if (landscape)
                    image.setRGB(y, width - x - 1, value);
                else
                    image.setRGB(x, y, value);
            }
        }

To the developer,

Could you please incorporate the above code? I'd love to have this whole thing
working with my Droid.

Thanks to everybody :)

wow, thank you all !
I've only a G2 so i can't test on the droid...
I'll test your change on my phone, if it works ok, i'll incorporate it to 0.4

YIPPEEE. I can see my droid just fine. Thanks to the dev and tjcSmith. 
Fantastic job.

Now what would it take to have the mouse and keys working for the droid as well?

Thanks a lot

I would LOVE to see this app working on the droid with full mouse and keyboard
function. Let me know what I need to do to help and I will do what I can. I have
tested and mine displays fine like others but no kb/mouse function other then 
the
right click.

See Issue #13 for a hack to get it working on a rooted droid.  Basically 
starting an 
emulator from the SDK "Virtual Devices" and getting application running on 
that, 
copying the /data/dalvik-cache file from the emulator to your PC, and then 
getting that 
file onto /data/dalvik-cache on your rooted droid

OutOfMemoryError seems to occure when using Android SDK 2.0 devices...
There have been some change to screen capture protocol
