在使用react-native-image-crop-picker(版本0.20.0)组件选择图片的时候，我希望将选取的图片保存到应用内部。
但是在ios端，选取的图片被保存在临时目录中，大约3天左右会被自动删除。
在android端，选取的图片没有往App内部保存，还是在原来的位置，组件只是返回了图片的存储位置。
要解决这个问题，修改该组件ios和android端的源码即可。
1.android端
修改node_modules\react-native-image-crop-picker\android\src\main\java\com\reactnative\ivpusic\imagepicker\PickerModule.java文件
修改如下
