Hey,
This is my code I use to display a preview from the camera on a
SurfaceView:
public void surfaceChanged(SurfaceHolder holder, int format, int w,
int h) {
Camera.Parameters parameters = mCamera.getParameters();
List<Size> cameraSizes =
CameraReflect.getSupportedPreviewSizes(parameters);
if(cameraSizes != null && cameraSizes.size() > 0) {
parameters.setPreviewSize(Math.max(cameraSizes.get(0).width,
cameraSizes.get(0).height), Math.min(cameraSizes.get(0).width,
cameraSizes.get(0).height));
}
else {
parameters.setPreviewSize(Math.max(w, h), Math.min(w, h));
}
mCamera.setParameters(parameters);
mCamera.startPreview();
}
It's pretty basic stuff; it uses reflection to determine if the
version of Android the user is running supports the
getSupportedPreviewSizes() method. If it does it obtains the width and
height and sets these as the preview size. If the version of Android
is older it will just set it as the width and height returned by the
SurfaceView.
However, it seems the Motorola Droid/Milestone doesn't like this code
and will instead show a blank screen instead of the camera preview.
Could someone kindly tell me where i'm going wrong?
Thanks
