答
您不能简单的，如果它位于你的应用程序的专用存储传递文件的路径。问题是，其他的应用程序没有权限读取的应用程序，从而尝试将失败。
You cannot simply pass the file path if it is located in your app's private storage. The problem is, the other application does not have permissions to read the app, and thus would fail while trying.
您必须实现一个 的ContentProvider ，或者更特异性地，一个的 FileProvider 。
You'll have to implement a ContentProvider, or more specificly, a FileProvider.
