Android图片压缩

比较简单，直接上代码
    public static Bitmap compressImage(Bitmap bitmap) {        if (bitmap != null) {            ByteArrayOutputStream baos = new ByteArrayOutputStream();            bitmap.compress(CompressFormat.JPEG, 100, baos);            int length = baos.size();            Logger.d("compressImage", "before compress  size:" + (length/1024) + "KB");            final int MIN_BYTE = 200 * 1024;            //小于200K就放过它吧            if (length > MIN_BYTE) {                Logger.d("compressImage", "large than 200KB begin compress.");                //压缩比例公式，可自行定义                int quality = (int) (((length - MIN_BYTE) / 5.0 + MIN_BYTE) * 100 / length);                Logger.d("compressImage", "compress rate:" + quality + "%");                baos.reset();                if (bitmap.compress(CompressFormat.JPEG, quality, baos)) {                    byte[] bs = baos.toByteArray();                    length = bs.length;                    Logger.d("compressImage", "compress success new size:" + (length/1024) + "KB");                    ByteArrayInputStream bais = new ByteArrayInputStream(                            bs);                    return BitmapFactory.decodeStream(bais);                }            } else {                Logger.d("compressImage", "Not compress less than 200K size:" + (length/1024) + "KB");            }        } else {            Logger.d("compressImage", "decode bitmap error");        }        return bitmap;    }
