I am getting this error on my Archos 32 Android device. I found this post : Droid's mediaserver dies on camera.takePicture()
But it's not very specific as to what "missing pieces" are besides the preview.
My code runs on the emulator and on at least one other droid device. Is there just an incompatibility with the archos or could I still be missing something?
The archos has a working camera program so I know it's possible to have an app that takes a picture but I'm beginnning to think there's some incompatibility with the sdk. Where can I download a complete working camera eclipse project? All I can find is code snippets.
Here's the debug log:

I also have an Archos32 exhibiting the same issue as you're having. Did you ever find an answer to your issue? I've checked out your code and my Archos32's mediaserver also dies upon trying to take a picture.
I have updated your code, though, and have it to a point where the media server doesn't die when taking a picture. I've basically updated Preview.java in the following manner:
public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
// Now that the size is known, set up the camera parameters and begin
// the preview.
Camera.Parameters parameters = camera.getParameters();
List<Size> previewSizes = parameters.getSupportedPreviewSizes();
Size optimalPreviewSize = previewSizes.get(0);
// parameters.setPreviewSize(w, h); // seems to crash if this code is enabled
parameters.setPreviewFormat(ImageFormat.JPEG);
parameters.setPreviewSize(optimalPreviewSize.width, optimalPreviewSize.height);
camera.setParameters(parameters);
camera.startPreview();
}
This is pretty down & dirty, because I'm not doing anything special to determine which preview size to use for the camera preview - I'm just grabbing the first one found - but the outcome of the changes I have made are that the media server no longer crashes onShutter(), and rawCallback() and jpegCallback() are now called, too.
If you want, you can grab the getOptimalPreview method from Google's CameraPreview API Demo to get the "optimal" preview size to use when taking a picture.
Let me know if this works for you - I've been fighting with my Archos for hours trying to get the camera implemented without crashing, and have finally started to make some progress.
