Preview is always 90 degree off

[aftabnaqvi]

Thanks for providing the great start sample with camera APIs.

On my Samsung Galaxy S4, preview is always 90 degrees off. It happens in both Landscape and portrait mode.

Any tips would be helpful.

Hi guys, follwing differents tutos on the web I found the problem for the camera preview

I just copy past the NativeCameraFragment in my project.

Update the optimatePreviewSize method, on my LGG3, the existing one gave me null size
With the following method it works fine for me

`
/**
*
* @param sizes
* @param width
* @param height
* @return
*/
private Camera.Size getOptimalPreviewSize(List<Camera.Size> sizes, int width, int height)
{
final double ASPECT_TOLERANCE = 0.1;
double targetRatio = (double) height / width;

        if (sizes == null)
            return null;

        Camera.Size optimalSize = null;
        double minDiff = Double.MAX_VALUE;

        int targetHeight = height;

        for (Camera.Size size : sizes) {
            double ratio = (double) size.height / size.width;
            if (Math.abs(ratio - targetRatio) > ASPECT_TOLERANCE)
                continue;

            if (Math.abs(size.height - targetHeight) < minDiff) {
                optimalSize = size;
                minDiff = Math.abs(size.height - targetHeight);
            }
        }

        if (optimalSize == null) {
            minDiff = Double.MAX_VALUE;
            for (Camera.Size size : sizes) {
                if (Math.abs(size.height - targetHeight) < minDiff) {
                    optimalSize = size;
                    minDiff = Math.abs(size.height - targetHeight);
                }
            }
        }

        return optimalSize;
    }
}
