This is a begin of a wrap for the Dropbox JAVA SDK
In fact v0.4 is a decompiled v0.28 library. I did changed it then to be able to compile it again. In my tests all is working now (all what i tested :D). The Library is still beta. But i´m now able to change things again ;-)

It is a request for the community too to parcitipate to this project doing test or writing documentation for the objects.

List of connected Tutorials:
- Dropbox SDK V2 - Authentification
- Dropbox SDK V2 - Uploading big files to Dropbox
- Dropbox SDK - get informed about changes in the used Dropbox


DropboxV2
Comment:
The Dropbox library allows you to communicate with Dropbox
Author: DonManfred (wrapper)
Version: 0.42 (wraps the SDK dropbox-core-sdk-3.0.7)

Wrapped Objects so far
  • DbxAuth
  • DbxClientV2
  • DbxHost
  • Dimensions
  • DbxRequestConfig
  • DbxUserAuthRequests
  • DropboxV2
  • DbxUserFilesRequests
  • FileMetadata
  • FolderMetadata
  • FolderSharingInfo
  • GpsCoordinates
  • Mediainfo
  • MediaMetadata
  • Metadata
  • RelocationPath
  • DbxUserSharingRequests
  • MemberSelector
  • SharedFileMetadata
  • SharedFolderMetadata
  • SharedLinkMetadata
  • BasicAccount
  • FullAccount
  • DbxUserUsersRequests

The Download will always be here in Post #1 of the Thread.

Additional to the provided Library (xml and jar) you need to download:
1. dropbox-core-sdk-3.0.7 Copy the file to your additional libraries folder.
2. jackson-core-2.7.4.jar. Extract from the zip attached and copy the file to your additional libraries folder.


In the following posts i´ll add some more detailed info on the different Objects.

Part 1 - Authentification

Connected Tutorial: Dropbox SDK V2 - Authentification

  • DbxUserAuthRequests
    Methods:
  • tokenRevoke As void
  • toString As java.lang.String
  • IsInitialized As boolean
    You will need this Object to revoke a given token. Usually you dont need it. The Authentification is done through the DbxAuth object (see the following description).... The DbxUserAuthRequests object is given by calling "auth" from the DropboxClient-Object

Usually you dont have a token if you want to connect to a users dropbox.

In this case we need to follow the OAuth-Flow to get an AccessToken.

to prepare yor app to use the Auth-Activity from dropbox you need to add this snippet to your Manifest-Editor

AddApplicationText(<activity
android:name="com.dropbox.core.android.AuthActivity"
android:configChanges="orientation|keyboard"
android:launchMode="singleTask" >
<intent-filter>
<data android:scheme="db-xxx" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>)

Please note that you need to change the scheme line
change db-xxx in db-yourappkey

To start the flow you need to have a
B4X:
    Dim auth As DbxAuth
   Dim config As DbxRequestConfig
   Dim dbxFiles As DbxUserFilesRequests
   Dim dbxSharing As DbxUserSharingRequests
   Dim dbxUsers As DbxUserUsersRequests
followed (in activity create) by a
B4X:
auth.Initialize("xxx")
where xxx is your appid from dropbox.

Start the Authentification from within a button click for example

B4X:
auth.startOAuth2Authentication
Check the OAuthtoken in activity resume

B4X:
Sub Activity_Resume
    If auth.OAuth2Token <> Null Then
        If auth.OAuth2Token <> "" Then
            token = auth.OAuth2Token ' token is a global string i used here
            lblToken.Text = token ' this is the label define in my testproject holding the token
            DropboxEnabled = True ' to know Dropbox can be used now
            btnListroot.Enabled = True ' in my example the button to do something is only clickable after Authentification.
            Starter.kvs.Put("token", token) ' Store token to a kvs
            Log("Token available. Dropbox enabled")
            config.Initialize("",token,"","de-de",5) '
            Dim dbxhost As DbxHost
            dbxhost.Initialize
            client.Initialize("Dropbox",config,token,dbxhost)
After this we can use Dropbox.

Please note that the lib contains several objects to do something.

All request-objects you get from the initialized client. NOTE that the request-objects have not yet set a Eventname...

You need to set the Eventname (and a correct ref to b4a) with

B4X:
        dbxFiles = client.files
        dbxFiles.setEventname("dbxFiles")
        dbxSharing = client.sharing
        dbxSharing.setEventname("dbxSharing")
        dbxUsers = client.users
        dbxUsers.setEventname("dbxUsers")
NOW you are ready to go

Following the code for the Auth-Example

B4X:
#Region  Project Attributes
    #ApplicationLabel: B4A Example
    #VersionCode: 1
    #VersionName:
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: unspecified
    #CanInstallToExternalStorage: False
#End Region

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: True
#End Region

The following appends to ALL Requests (UserRequests, Files-Requests and Sharing-Requests)!

Note that all calls to one of the methods will be handled in a new Thread and after it finishes a event is raised.

For example: a call to CurrentAccount will raise the event CurrentAccount(account As FullAccount). A similar Event will be raised by all other methods too.

Part 2 - UserRequests (finished)
  • DbxUserUsersRequests
    Events:
  • getAccount (account As BasicAccount)
  • getCurrentAccount (account As FullAccount)
  • getAccountBatch (batch As List)
  • getSpaceUsage (usage As SpaceUsage)
    Methods:
  • Account (accountId As java.lang.String) As void
  • CurrentAccount As void
  • AccountBatch (accountIds As java.util.List) As void
  • IsInitialized As boolean
  • setEventname (ba As anywheresoftware.b4a.BA, EventName As java.lang.String) As void
    Properties:

    the files with the following extensions: .doc, .docx, .docm, .ppt,
    .pps, .ppsx, .ppsm, .pptx, .pptm, .xls, .xlsx, .xlsm, .rtf.
  • getcopyReference (path As java.lang.String) As void
    Get a copy reference to a file or folder. This reference
    string can be used to save that file or folder to
    another user's Dropbox by passing it to copy_reference/save.
  • createFolder2 (path As java.lang.String, autorename As boolean) As void
    Create a folder at a given path.
    If autorename is set to true then the new folder will become
    renamed automatically.

  • IsInitialized As boolean
  • getThumbnail (path As java.lang.String, format As com.dropbox.core.v2.files.ThumbnailFormat, size As com.dropbox.core.v2.files.ThumbnailSize, localPath As java.lang.String, localFilename As java.lang.String) As void
    Get a thumbnail for an image.
    This method currently supports files with the following
    file extensions: jpg, jpeg, png, tiff, tif, gif and bmp.

    Photos that are larger than 20MB in size won't be
    converted to a thumbnail.
  • getPreview2 (path As java.lang.String, rev As java.lang.String, localPath As java.lang.String, localFilename As java.lang.String) As void
    Get a preview for a file. Currently previews are only generated for
    the files with the following extensions: .doc, .docx, .docm, .ppt,

  • listRevisions2 (path As java.lang.String, limit As long) As void
    Return revisions of a file.
  • delete (path As java.lang.String) As void
    Delete the file or folder at a given path. If the path is a
    folder, all its contents will be deleted too.
    A successful response indicates that the file or folder was
    deleted. The returned metadata will be the corresponding
    FileMetadata or FolderMetadata for the item at time of
    deletion, and not a DeletedMetadata object.
  • deleteBatch (entries As java.util.List) As void
    Delete multiple files/folders at once.
    This route is asynchronous, which returns a
    job ID immediately and runs the delete batch
    asynchronously. Use delete_batch/check to
    check the job status.
  • setEventname (ba As anywheresoftware.b4a.BA, EventName As java.lang.String) As void
  • saveUrl (path As java.lang.String, url As java.lang.String) As void
    Save a specified URL into a file in user's Dropbox.
    If the given path already exists, the file will be
    renamed to avoid the conflict (e.g. myfile (1).txt).
  • search (path As java.lang.String, query As java.lang.String, mode As java.lang.String, maxResults As long, startAt As long) As void
    Searches for files and folders.
    Note: Recent changes may not immediately be
    reflected in search results due to a short
    delay in indexing.
  • download (path As java.lang.String, localPath As java.lang.String, localFilename As java.lang.String) As void
    Downloads the file "path" and store it in the
    path "localPath" under the filename "localFilename".
    DEV:Tested
  • download2 (path As java.lang.String, rev As java.lang.String, localPath As java.lang.String, localFilename As java.lang.String) As void
    Downloads the file "path" with the revision "rev" and store it
    in the path "localPath" under the filename "localFilename".
    DEV:NOT Tested
  • MoveBatchCheck (asyncJobId As java.lang.String) As void
    Returns the status of an asynchronous job for move_batch.
  • copyBatch (entries As java.util.List) As void
    Copy multiple files or folders to different locations at once in the
    user's Dropbox. If RelocationBatchArg.allow_shared_folder is false,
    this route is atomic. If on entry failes, the whole transaction will
    abort. If RelocationBatchArg.allow_shared_folder is true, not
    atomicity is guaranteed, but you will be able to copy the contents
    of shared folders to new locations.
    This route will return job ID immediately and do the async copy job
    in background. Please use copy_batch/check to check the job status.
  • listFolderLatestCursor (pba As anywheresoftware.b4a.BA, path As java.lang.String, includeDeleted As boolean, includeHasExplicitSharedMembers As boolean, includeMediaInfo As boolean, recursive As boolean, debuglog As boolean) As void
    A way to quickly get a cursor for the folder's state. Unlike
    list_folder, list_folder/get_latest_cursor doesn't return any
    entries. This endpoint is for app which only needs to know
    about new files and modifications and doesn't need to know
    about files that already exist in Dropbox.
  • listFolderLongpoll (cursor As java.lang.String) As void
    A longpoll endpoint to wait for changes on an account. In conjunction
    with list_folder/continue, this call gives you a low-latency way to
    monitor an account for file changes. The connection will block until
    there are changes available or a timeout occurs.
  • createFolder (path As java.lang.String) As void
    Create a folder at a given path.
  • copy (fromPath As java.lang.String, toPath As java.lang.String) As void
    Copy a file or folder to a different location
    in the user's Dropbox. If the source path is
    a folder all its contents will be copied.
    fromPath:
    toPath: DEV:not tested!
  • permanentlyDelete (path As java.lang.String) As void
    Permanently delete the file or folder at a given
    path (see https://www.dropbox.com/en/help/40).
    Note: This endpoint is only available for Dropbox Business apps.
  • move (fromPath As java.lang.String, toPath As java.lang.String) As void
    Move a file or folder to a different
    location in the user's Dropbox.
    If the source path is a folder
    all its contents will be moved.
  • getMetadata (path As java.lang.String, includeDeleted As boolean, includeHasExplicitSharedMembers As boolean, includeMediaInfo As boolean, debuglog As boolean) As void
    Returns the metadata for a file or folder.
    Note: Metadata for the root folder is unsupported.
    path: DEV:not tested!
  • restore (path As java.lang.String, rev As java.lang.String) As void
    Restore a file to a specific revision.
  • getDownloadbuilder (path As java.lang.String) As com.dropbox.core.v2.files.DownloadBuilder
  • listFolder (pba As anywheresoftware.b4a.BA, path As java.lang.String, includeDeleted As boolean, includeHasExplicitSharedMembers As boolean, includeMediaInfo As boolean, recursive As boolean, debuglog As boolean) As void
    Lists the content from path "path"
    - If "includeDeleted" is set to true then deleted
    files/folders are listed too. See Metadata for
    details on each entry.

    - is "includeHasExplicitSharedMembers" is set to
    true then "i dont know what happens ;) See
    Dropbox site for more info ;-)

    - if "includeMediaInfo" is set to true then the
    result will ontain MediaInfo too (pictures and video)

    - If "recursive" is set to true then the Folder will
    be listed recursively. Note that this could result in
    a long list of Metadatas.

    - If "debuglog" is set to true then the lib will do
    some LOG-Output so see where it hangs

    DEV:Tested!
  • moveBatch (relocation As java.util.List, allowSharedFolder As boolean, autorename As boolean) As void
    Move multiple files or folders to different locations
    at once in the user's Dropbox.
    This route is 'all or nothing', which means if one entry
    fails, the whole transaction will abort.

    This route will return job ID immediately and do
    the async moving job in background. Please use
    move_batch/check to check the job status.
  • copyBatchCheck (batchID As java.lang.String) As void
    Returns the status of an asynchronous job for
    copy_batch. If success, it returns list of
    results for each entry.
  • listFolderLongpoll2 (cursor As java.lang.String, timeout As long) As void
    A longpoll endpoint to wait for changes on an account. In conjunction
    with list_folder/continue, this call gives you a low-latency way to
    monitor an account for file changes. The connection will block until
    there are changes available or a timeout occurs.
  • getTemporaryLink (pba As anywheresoftware.b4a.BA, path As java.lang.String) As void
    Get a temporary link to stream content of a file.
    This link will expire in four hours and afterwards
    you will get 410 Gone.
    Content-Type of the link is determined
    automatically by the file's mime type.
  • saveUrlCheckJobStatus (asyncJobId As java.lang.String) As void
    Check the status of a save_url job.
  • deleteBatchCheck (batchID As java.lang.String) As void
    Returns the status of an asynchronous job for
    delete_batch. If success, it returns list
    of result for each entry.

Methods:
  • relinquishFileMembership (fle As java.lang.String) As void
    The current user relinquishes their membership in
    the designated file. Note that the current user
    may still have inherited access to this file
    through the parent folder.
    Apps must have full Dropbox access to use this endpoint.
  • addFolderMember (sharedFolderId As java.lang.String, members As java.util.List) As void
    Allows an owner or editor (if the ACL update policy allows)

A couple of very important features in @DonManfred new Dropbox V2 lib are UPLOAD and DOWNLOAD files. I like to share the code for both with examples:
B4X:
Dim MyImport, MyExport As String
            Dim MyPath=File.DirRootExternal, MyFile ="germany.txt" As String
            MyImport="/Import"   'dropbox server subfolder
            MyExport="/Export"   'dropbox server subfolder
           
            'TO UPLOAD A FILE: if autorename is set to true and uploaded file has same name,
            'but its content changed, the file is not overwritten: e.g.: germany (1).txt                               
            dbxFiles.upload(MyPath, MyFile, MyImport &"/" & MyFile,False,False)  
           
            'TO DOWNLOAD A FILE TO DEVICE:
            dbxFiles.download(MyExport & "/" & MyFile, MyPath, MyFile)

I’m trying the DropboxV2V0.28 lib.

I have downloaded and copied the dropbox-core-sdk-2.1.2.jar and Jackson-core-2.7.4.jar as per your instructions
I have downloaded and installed the DropboxV2Example1-Auth.zip.
Compilation proceeds Ok but I get an error on line 43 – Activity.LoadLayout(“OAuth”)

Also, OAuth layout can not be opened in the Designer :
Error loading file - Unknown type: 12
upload_2016-12-19_20-5-32.png

What am I doing wrong?

Error downloading and uploading, please help me.
Did you added the two additional jars to your additional libs folder successfully?
This is the only i can think where this could come from.

Additional to the provided Library (xml and jar) you need to download:
1. dropbox-core-sdk-2.1.2.jar. Copy the file to your additional libraries folder.
2. jackson-core-2.7.4.jar. Copy the file to your additional libraries folder.
The file in you error message is part of the dropbox-core-sdk-2.1.2.jar

What is the correct syntax for the files delete event please? I currently get 'java.lang.Exception: Sub dbxfiles_delete signature does not match expected signature.' using dbxFiles_Delete (success As Boolean, meta As FileMetadata, error As String).

I currently get 'java.lang.Exception: Sub dbxfiles_delete signature does not match expected signature.
The problem is that i raise the Event from the code but i forgot to declare the Event in the wrapper.

Try it with this version please.

Thanks, but I'm still getting the same error. It seems to happen every other time the file is deleted. When it doesn't error, the FileMetaData is returned as null. The file is deleted either way.

Edit: The times is isn't failing are when the file isn't there to delete. It successfully deletes the file when present but still errors with 'java.lang.Exception: Sub dbxfiles_delete signature does not match expected signature.'. Should the FileMetaData in 'Sub dbxFiles_Delete (success As Boolean, meta As FileMetadata, error As String)' be DeletedFileMetaData ?

Any ideas please?

In an objective C version of my app using Api V1 I was able to check the revision of a file then upload with the parent revision to replace it. Using the SDK I seem to be stuck checking for the file and trying to delete it if it already exists - which I'm unable to do without an untrappable error at the moment.

Cheers, Gavin.

I wrote the lib in the early V2-stage. Maybe the V2 Api changed... At the time i wrote the lib it was not possible to use a revision when you UPLOAD a file. You could list all revisions of a file. Or restore a file using it´s revision.

I checked the documentation this morning and i found indicators on how to do it.

Need to investigate but i´m limited in time having these days

I checked the documentation this morning and i found indicators on how to do it.
Sadfully i was looking at the http documentation.

After checking the java code and Dropbox jar it looks that there is no method to upload a file using a revision.
Even not using a "Parent revision".



In the Uploadbuilder are only properties for AutoRenaming and for silent uploads (mute).
