more features:

   new PhotoHelper(activity) //create a helper instance
        .quality(80) //try compress image using the quality 80 图片的质量,100为最高
        .maxWidth(120,true) //try scale image unless with < 120dp,default is screen width 图片的最大宽度
        .maxFileSizeKB(80) //try compress image unless file size < 80KB 图片文件的最大值,如果文件大于此值会进行压缩(牺牲清晰度)
        .cropping(true) //cropping the target image 是否进行剪裁,如果为true则选择完图片后会进入剪裁页
        .cropFactor(0.8f)// crop area factor 剪裁边框的大小,0.8表示宽的80%
        .autoRotate(true) //try rotate the image according to photo exif information (some samsung devices need to rotate)
        .callback(new PhotoHelper.CallBack() { // set callback 完成后的回调
                    @Override
                    public void done(File imageFile) {
                        //do something
                    }

                    @Override
                    public void error(Exception e) {
                        //error
                    }
                }) 
        .takePhoto() //or choosePhoto(), just do the job for you

some util method:

PhotoHelper.saveBitmap2File(Bitmap bitmap,File targetFile,int quality) //save bitmap to file
PhotoHelper.getBitmap(File imageFile,int maxWidthInPx) //get Bitmap from a file and try scale image with max width
PhotoHelper.rotateBitmap(Bitmap bitmap , int angle) //rotate image
PhotoHelper.rotateBitmap(String src , Bitmap bitmap) //rotate image according to photo exif information
