BitmapFactory.decodeByteArray为null

YuvImage image = new YuvImage(data, ImageFormat.NV21, size.width, size.height, null);
if(image!=null){
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    image.compressToJpeg(new Rect(0, 0, size.width, size.height), 80, stream);
    byte[] bytes = stream.toByteArray();
    bmp = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
    imageView.setImageBitmap(bmp);
    stream.close();

请描述你碰到的具体错误

断点调试，看你的image是不是空的

byte的数据无法转换为bitmap
