I'm testing my application on Samsung Galaxy Ace, and I get the supported sizes with
cameraParams.getSupportedPictureSizes();
It works with all of them except of (320 x 240) - the preview turns black and I get this error: Camera Error 100
Camera Error 100 - "Media server died. In this case, the application must release the Camera object and instantiate a new one."
Do what the SDK says and release the camera object and make a new one.

I had error 100 on samsung galaxy s3. The problem in my case was in camera dimensions. I followed android developers camera guide and was setting video size (setVideoSize (widht,height)) in prepareVideoRecorder();
But I was setting wrong dimension what caused camera freeze,crash with error 100 and "camera server died".
The solution is:
adding next two lines
mPreviewHeight = mCamera.getParameters().getPreviewSize().height;
mPreviewWidth = mCamera.getParameters().getPreviewSize().width;
in block (in surfaceChange method):
try {
mPreviewHeight = mCamera.getParameters().getPreviewSize().height;
mPreviewWidth = mCamera.getParameters().getPreviewSize().width;
mCamera.setPreviewDisplay(mHolder);
mCamera.startPreview();
} catch (Exception e){
Log.d(TAG, "Error starting mCamera preview: " + e.getMessage());
}
and then in prepareVideoRecorder() setting this parameters to camera:
mMediaRecorder.setVideoSize(mPreviewWidth, mPreviewHeight);
