android头像上传（获取头像加剪切）
因为项目中需要用到头像上传的功能，所以就下个Ddmo先来实现下。
demo我是类似仿微信的，在一个GridView中展示所有的图片，其中第一个item可以去照相；获取到图片后再进行剪切。
图片的剪切是从网上找的感觉不错就用，暂时也没有测试。
获取图片可以用：https://github.com/lovetuzitong/MultiImageSelector来实现
这里的圆形图像是用https://github.com/hdodenhof/CircleImageView来实现的
Demo写的比较粗糙，效果只是在4.4的手机和7.0的模拟器跑了一遍，所以可能会出现问题的。

如下是demo的效果图：
如下是选择图片中的代码
通过LoaderManager来获取到所有的图片，然后第一个进行拍照的处理

其中处理动态的权限还需要添加7.0的照相处理
在清单文件中加如下配置：
<provider android:name="android.support.v4.content.FileProvider" android:authorities="com.item.demo.photo.fileProvider" android:grantUriPermissions="true" android:exported="false"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths" /> </provider>
