如何使用外部应用程序访问存储在内部存储的自定义文件夹中的文件？

Question

I have a zip file. I am unzipping it to internal storage. When unzipping each file, I am keeping the same folder structure. After unzipping all levels, I want to display the files using appropriate third party apps like adobe reader etc.

I can unzipping and creating files with same folder structure. But the problem is the files could not be displayed through external app, because of permission. I couldn't set WORLD_READABLE PERMISSION, because the files are storing in custom folders. I applied setReadable also. But no hope.

How can I show files, or how to get permission to files?

Any help would be appreciated..

Thanks Jomia

Use FileProvider to serve up the files from your app's internal storage using a ContentProvider .

Or, put the files on external storage, instead of internal storage.
