            //AssetFileDescriptor fd = amanager.openFd(files[0]);

推荐答案

如果你得到一个 ActivityNotFoundException 是因为没有应用程序来处理该类型的内容。因此，在这种情况下，我敢肯定安装了Adobe Reader中。

If you get an ActivityNotFoundException is because there are no application to handle that kind of content. So, in that case, I'm sure the the Adobe Reader is installed.

另外，我觉得你必须将文件复制到SD卡的其他应用程序来访问它。他们不能直接访问您的私人数据安全方面的原因。

Also, I think you must copy the file to the SDCard for other apps to access it. They cannot access your private data directly for security reasons.
