Android Storage Access Framework Example

This is a sample of the android Storage Access Framework, but it currently fails to support rename on Google Docs Uri's.

• The Floating Action Button will launch the storage access framework UI
• The Options menu has save support (only works after opening file)
• The Options menu has a "rename" item, but it crashes when using a google doc file (only runs after opening file)

The rename button will work when using files on internal storage.

This is discussed here: http://stackoverflow.com/questions/35781369/renaming-document-in-google-docs-using-android-storage-access-framework-results

To reproduce the error:

1. Install this app and google drive/docs app
2. Open SafExample
3. Hit the Floating Action Button to open Storage Access Framework looking for text files
4. Open a txt file
5. Click "Rename" in the options menu once the txt file loads

At this point it crashes. Here is the error:
