代码如上，简单的调用剪切图片，但是在华为的Nexus6p 手机上，从相册中选择的图片却不能打开剪切界面，提示：Editing is not supported for this image
以下是我的解决办法，非常感谢 这位大神的帮助：http://my.csdn.net/a1002450926 （我是岩仔）的帮助
具体 原因是因为在android4.4以后，从相册获取图片的方法返回的Uri data ,由 file:// 路径变成 了 content://路径 以下方法可以通过判断 并获取到file://的路径，即可使用。同时也谢谢两位的回答

return-data", false 这个参数用false 指定输出图片试一下
参考代码

给你个建议，用第三方的图片选择或剪切吧 自己写这个又麻烦 还有兼容的问题
你这个问题我估计下很可能是你从图片选取的时候使用的 ACTION_GET_CONTENT 而不是ACTION_PICK
4,4以下使用ACTION_GET_CONTENT 以上使用而不是ACTION_PICK 而且使用而不是ACTION_PICK返回的path还要进行判断才能获得正确的地址
我估计是你在选择图片获得的地址就不对 然后进行裁剪才出现提示：Editing is not supported for this image
所以如果项目没有特殊要求 就直接用第三方的吧 个人推荐一个： galleryFinal 可以预览 可以裁剪 还可以吧
PS：QQ 497289807
打错字了。。。。 4.4以上使用ACTION_PICK
