Handling of content:// URIs

[gsantner]

General information

• Android Version: 7
• App version: 0.2.2

Steps to reproduce

Currently everything is handled as java.io.File. content:// URIs are just converted to File using getPath(), which will not work in many cases when data coming from other applications.

Expected result

• intent-filter for content URIs for DocumentActivity

• Content URIs get correctly handled aswell. Includes saving/writing/reading/isFolder/isFile/isReadonly. One has also to check that at content URIs >renaming< may not be possible.

• Ideally there is the current Document class contains a DocSource Object. Soirce is a Baseclass, has two derivates, one for file, one for content. Baseclass with an abstract boolean read/write/move/isFile/isFolder/isReadonly/isMoveable method. Parameters between activity are shared then with type Document or with the baseclass.

  • Maybe DocumentFile already has required stuff builtin? https://developer.android.com/reference/android/support/v4/provider/DocumentFile.html and openInput/OutputStream on getUri()

• Maybe note future addition of other sources, e.g. Network? A sync provider/library with callbacks? ..

I ran into this error when trying to open a Markdown file through the Dropbox Android app.

Is there any way to use Markor with Dropbox or another syncing service?

[gsantner]

Well it's more like a "this is not done yet" then an error :D. Note that any help is appreciated here.

Yep, I (and many others told me they do) use Syncthing for that. https://syncthing.net/

Another user told me he uses FolderSync with a WebDav share.

@paldepind : Markor got some <3 in the latest update regarding this. While you can't open files directly out of the DropBox app, you can now set the folder to STORAGE/Android/data/com.dropbox.android/files/u123456/scratch/ and edit files in there, thats the folder where Dropbox should sync all files too. Don't forget to check the Offline available mark in the dropbox app.

Thank you very much for this. For the record, Dropbox used to support setting the "make available offline" for a folder on the free version -- as of this writing, that is no longer the case, you have to upgrade to premium/subscription Dropbox for that. (Also for the record, you used to be able to connect more than 3 devices for sync on free Dropbox, that is also no longer the case).
