Dropbox has dropped support for this API. It doesn't work anymore.

The iDropboxSync library allows you to use Dropbox Sync service to manage an app specific folder inside the user Dropbox account.

It is similar to B4A DropboxSync library: http://www.basic4ppc.com/android/forum/threads/dropbox-sync-library.30112/

The user can easily access these files from any device or computer:



When the user runs the app for the first time they will be asked to grant access to your app. If Dropbox app is installed then the user only needs to click on the button. Otherwise they will need to log-in to their account.

You can see the authorization step in this video:


Using this library

1. You need to register an app with Dropbox that has access to a unique folder:
https://www.dropbox.com/developers/apps
You need to get two values: app key and app secret.

2. If you are using a local mac builder then you need to download the SDK to your Mac computer and copy Dropbox.framework to the Libs folder.

3. The authorization step happens outside of your app. To allow Dropbox app (or the browser) to return back to your app you need to add the following attribute:
B4X:
#UrlScheme: db-ret331arjio70t6
Change the value after db- to your app key.

Application_OpenUrl will be called after the authorization step. You need to call manager.HandleOpenUrl:
B4X:
Private Sub Application_OpenUrl(Url As String, Data As Object) As Boolean
   Log("openurl: " & Url)
   manager.HandleOpenUrl(Url)
   Return True
End Sub
The AccountReady event is raised when the account is ready or when there was a problem with linking the account.
Now you can download or upload files to the account and manage your app specific folder.

When you download a file the DownloadCompleted event is raised when the file is ready. Note that the library always checks that the file is up to date (similar to B4A AutoSync flag).

Downloaded de MAC SDK and Copied Dropbox.framework to the Libs folder on the Macserver. I get multiple error at compile time with the dropboxsync example. What am I doing wrong? Should I copy the dropbox.framework folder or the contents of the Version/A/Headers, etc. folder?

My “mistake” Erel. I was using the “PC-Windows” file system when extracting and copying the Dropbox.framework to the Libs folder. Somehow, the Windows system does not “understand” the shortcuts, etc. that are used in the framework folder. When doing everything on the Mac side everything worked fine. Thanks for the help!

Hello: Still some problems with DropboxSync. I Use #PlistExtra: <key>UIApplicationExitsOnSuspend</key><true/> to stop my application when it goes to the background. When the app ask for authorization to access dropbox it exits and, when returning, it goes again to ask permission and so on. Any idea how I can go around this?

Yes, it is working fine in release mode if I don't use the "exitonsuspend" feature. Otherwise the app entera that loop asking permission.

Hi,

I am very interested to get this function for my iphone app which required a constant upload of text/data file from outside.

my build B4i ver1.8, Dropboxsync V3.0

Problem running your example :
1. I went to https://www.dropbox.com/developers/apps, created a APP under DropBox API app
2. replace the APPkey and AppSecret strings in your example.
3. when I run the example I get this msg
upload_2015-2-13_10-19-1.png


What am I missing?
Thanks

I would like to be able to setup a central Dropbox folder so all my app users can upload data to it. Is that possible?

I am not that familiar with all the features of Dropbox sharing but with the current limitation that the app can only access a folder under the Apps/AppName folder means that folder would need to be shared and still be located under the Apps/AppName folder on everyone's Dropbox. Is that possible?

When I setup for Dropbox access by the app there is an option to access already existing files in a Dropbox. Would that also allow access to already existing folders? If so how would that be coded in B4i to access an already existing folder?

This is excellent, thanks!
Do you know if it's possible to also add comments to the files that are uploaded?

thanks.
one more question - I can export from DirAssets to Dropbox, but don't seem to be able to from DirDocuments.
I get a 'cannot read' file error in the logs.

This is the code
B4X:
    For n = 0 To clvPics.GetSize - 1
        Dim pnl As Panel
        pnl = clvPics.GetPanel(n)
        Dim getID As String
        getID = pnl.GetView(0).Tag
        Dim img1 As ImageView
        img1.Initialize("")
        img1 = pnl.GetView(0)
        Dim outPic As OutputStream = File.OpenOutput(File.DirDocuments, "DBshare", False)
        img1.Bitmap.WriteToStream(outPic, 100, "png")
        outPic.close
        'upload file
        manager.UploadFile(File.DirDocuments, "DBshare.png", "/", getID & ".png")
    Next
and this is the error message, (with bits omitted for privacy?)

Error uploading file: Error Domain=dropbox.com Code=-10008 "The operation couldn’t be completed. (dropbox.com error -10008.)" UserInfo=xxxxxx {ctx=-[DBFilesystem file:writeContentsOfFile:shouldSteal:error:], desc=FILE_IO: file.cpp:663: cannot read /var/mobile/Containers/Data/Application/xxx-xxx-xxx-xxx-xx/Documents/DBshare.png}

Thanks for any help!
