You need to set video-size parameter to the correct value. I had the same problem - preview size was 640x480 and the preview appeared stretched while using setRecordingHint(true). I then used getParameters().flatten() to print out all parameters set for my Camera device. My video-size parameter was actually set to 1920x1080 causing the incorrect aspect ratio. You can change this parameter using params.set("video-size", "WxH"). Only then is the aspect ratio correct.
