#### 2.问题描述：

升级6后，IDE的文件浏览，图库不显示目录名了，都是数字，找图片困难。

#### 解决方案：

"媒体文件uri的格式类型：
  - 图片uri格式：file://media/Photo/<id>/IMG_datetime_0001/displayName.jpg。
  - 视频uri格式：file://media/Photo/<id>/VID_datetime_0001/displayName.mp4。

#### 3.问题描述：

升级前后IDE中文件浏览都显示的是id。"
"这个api的结果是否支持回传选择图片的类型，比如选择了一个动态图片和静态图片，如何区分是否是动态图片？

#### 解决方案：

可以通过获得photoAsset的photoSubtype来获得图片类型，可参考<a href="elink@1e7K9s2c8@1M7s2y4Q4x3@1q4Q4x3V1k6Q4x3V1k6V1k6i4k6W2L8r3!0H3k6i4u0Q4x3X3g2Z5N6h3q4%4k6h3W2Q4x3X3g2U0L8$3#2Q4x3V1k6U0L8$3&6K6N6h3#2W2M7W2)9J5c8X3y4F1i4K6u0r3k6r3!0U0i4K6u0r3K9r3q4J5L8h3!0F1P5h3!0K6i4K6u0V1M7X3g2X3k6i4u0W2L8X3y4W2M7#2)9J5c8X3q4J5K9%4c8K6i4K6u0V1j5i4m8A6M7#2)9J5k6s2m8Z5L8%4c8G2j5h3y4U0k6i4y4K6K9r3g2D9M7r3g2J5i4K6u0V1k6g2)9J5x3%4m8Z5L8%4c8G2K9$3g2&6M7H3`.`.">PhotoKeys</a>，photoviewpicker只是通过select方法获取uri，并把该资源访问授权给用户，用户需要通过该uri去获得相应资产，即photoAccessHelper.PhotoAsset，获得asset后通过get方法获得对应的属性photoSubtype。
