我有一个PDF文件,我从服务器下载,有时用户上传损坏的PDF,我需要检查我的应用程序是否可以打开这样的文件.

那么我可以使用内置的方法来检查PDF损坏吗？如果没有,我可以用来查看或检查损坏的免费轻量级PDF框架？

注意:目前我在UIWebView上打开PDF文件.

我正在尝试使用Glide加载带有URI"content://com.android.contacts/contacts/295"的联系人照片.

我用的时候

Glide.with(context).load(Uri.parse(contactPhoto).into(imageview)

Glide给了我一个FileNotFoundException

java.io.FileNotFoundException: File does not exist; URI: content://com.android.contacts/contacts/264, calling user: android.uid.shared:10006, calling package is one of: [com.android.providers.contacts, com.android.contacts, com.android.providers.userdictionary]

显然Glide试图从错误的地方获取图像.

如果有人指出我如何使用"content://"URI加载照片,我将不胜感激.
