B4A Class Dropbox API V2. All HTTP! All using httputils2

DonManfred · Aug 2, 2015

Update April 2017:
Google has changed the ability to use a Webview to get an OAuth-Token. Due to this change it no longer works to get an OAuth-Token using a Webview.
This library is not useable anymore except if you use the Lib only using YOUR token which is hardcoded in your app. This will work.
But if you need to get Access to a Users Dropbox then you can´t use this lib anymore. I suggest to switch to my Java-Wrap for the Drobox Api V2. Here you are able to get an OAuth-Token as this lib does not depend on a Webview.

-----------------------------------------------------------------------------

As you can read here Dropbox has decided to deprecate the Sync and Datastore APIs over the next 12 months. Drobox has now released an new preview site for the new V2 API

Dropbox released an API Explorer for their V2 api.
See the announce too for the explorer.

--------------------------------------------------------------------------------------------------------------------------------------------

This thread is about the HTTP version of the new Dropbox V2 api.
See the documentation here: https://www.dropbox.com/developers-preview/documentation/http#documentation

The attached B4A Library is using this new HTTP Api

The Library is available as Library (jar + xml). Please download DropboxV2_libraryfiles_v091.zip to get the files. Extract the content to your additional Librariespath

Please download DropboxHTTPv2librarysource_V0.91 if you want to change the class. Use this project and compile it to a library to get the correct jar and xml created by yourself
In most cases you dont need this one.

Methods:
- IsInitialized As Boolean
  Tests whether the object has been initialized.
- add_folder_member (shared_folder_id As String, email As String, dropbox_id As String, access_level As String, quiet As Boolean, custom_message As String) As String
  Allows an owner or editor (if the ACL update
  policy allows) of a shared folder to add
  another member.
  For the new member To get access To all the
  functionality For this folder, you will need
  To call mount_folder on their behalf.
  Warning: This endpoint Is in beta And Is subject To
  minor but possibly backwards-incompatible changes.
- check_job_status (async_job_id As String) As String
  Returns the status of an asynchronous job.
  Warning: This endpoint Is in beta And Is subject To
  minor but possibly backwards-incompatible changes.
- check_share_job_status (async_job_id As String) As String
  Returns the status of an asynchronous job for
  sharing a folder.
  Warning: This endpoint Is in beta And Is subject To
  minor but possibly backwards-incompatible changes.
- copy (fromPath As String, toPath As String) As String

  Note that in the returned PathLinkMetadata, the
  PathLinkMetadata.url field Is the shortened URL
  If CreateSharedLinkArg.short_url argument Is set
  to True.
  Previously, it was technically possible To break
  a shared link by moving Or renaming the corresponding
  File Or folder. In the future, this will no longer
  be the Case, so your app shouldn't rely on this
  behavior. Instead, if your app needs to revoke a
  shared link, use revoke_shared_link.

First we need to initialize the Class

B4X:

dbx.Initialize(Me,"DropBox","access_token",True)

If you want to use the class just "with your dropbox" then you can create a access_token in the Dropbox App console.

You can find an example of not using pre-created access_token in Post #45 of this thread.. It is using the OAuth2 Flow to get access to a users Dropbox.

In order they are listed on the Previewdocumentation site i´ll post Examples (or just description on how to) for each of the used endpoints.

B4X:

dbx.GetAccount("dbid:AAB2cfhttqMg1RjLLRlFzYWWoY6lUpWKsKo")
' Event
Sub DropBox_Account(meta As Map)
    Log("Dropbox_Account: "&meta)
End Sub

Get information about a user's account. In this case it wil get informations about MY (DonManfred) dropboxaccount.

B4X:

dbx.GetCurrentAccount
' Event
Sub DropBox_CurrentAccount(meta As Map)
    Log("Dropbox_CurrentAccount: "&meta)
End Sub

Get information about the current user's account. It will result in giving YOUR (the developer) account.

B4X:

dbx.GetSpaceUsage

' Event
Sub DropBox_SpaceUsage(space As Map)
    Log($"DropBox_SpaceUsage(${space})"$)
End Sub

Get the space usage information for the current user's account.

B4X:

dbx.GetMetadata("/b4arulez.gif")

' Event
Sub DropBox_MetaData(meta As Map)
    Log("Dropbox_MetaData: "&meta)
End Sub

Returns the metadata for a file or folder.

B4X:

dbx.Listfolder("/Export")
' dbx.ListfolderContinue is called from the result-sub
' automatically if there are more results

' Event
Sub DropBox_ListFolder(meta As Map)
    Log("Dropbox_Listfolder: "&meta)
    Dim cursor As String = meta.Get("cursor")
    Dim has_more As String = meta.Get("has_more")
    Dim entries As List = meta.Get("entries")
    For Each colentries As Map In entries
        Dim path_lower As String = colentries.Get("path_lower")
        Dim name As String = colentries.Get("name")
        filelistfolder.Add(name)

        Dim tag As String = colentries.Get(".tag")
    Next
    If has_more = True Then
        dbx.ListfolderContinue(cursor)
    Else
        Log("No more files")
        Log($"FilesInFolder(${filelistfolder.Size})"$)
        For i = 0 To filelistfolder.Size-1
            LogColor(filelistfolder.Get(i),Colors.Yellow)
        Next
        Dim resulting_files As List = WildCardFilesList(filelistfolder,"*.csv",True,True)
        For i = 0 To resulting_files.Size-1
            LogColor(resulting_files.Get(i),Colors.Green)
        Next

        'kvs.PutObject("filelistfolder", filelistfolder)
    End If

End Sub

Returns the contents of a folder.
NOTE (from Dropbox): We're definitely going to streamline this interface.

B4X:

dbx.GetLatestCursor("/",False)

' Event
Sub DropBox_LatestCursor(meta As Map)
    Log("DropBox_LatestCursor()")
    Dim cursor As String = meta.Get("cursor")
    longpollcursor = cursor
    kvs.PutSimple("longpollcursor",cursor)
    Log("longpollcursor set: "&cursor)
End Sub

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.

B4X:

dbx.Download("/9-patch-assets.zip",File.DirDefaultExternal,"9patch.zip")


' Event is missing as yet.

Download a file from a user's Dropbox.
As i´m writing this forumpost i see that this method is missing a event when finished. It is working and saving the file as you can see it in the logs but the event is missing. TODO

B4X:

    Dim session As Map
    session.Initialize
    session.Put("srcpath","/storage/emulated/0/Download")
    session.Put("srcfile","20150716151904894.pdf")
    session.Put("dstpath","/Export")
    session.Put("dstfile","20150716151904894.pdf")
    session.Put("offset",0)
    session.Put("packetsize",16384)
    dbx.UploadSessionStart(session)
' This is raising multiple events.

End Sub
Sub DropBox_UploadSessionFinish(session As Map)
    Log("DropBox_UploadSessionFinish()")
    Log(session)
End Sub

Start a new upload session. This is used to upload a single file with multiple calls. I´ve tried it with files up to 20mb but should work with 500mb as well.

B4X:

dbx.Upload(extsdcard,"app-release.apk","/","app-releaseTEST.apk")
' Event
Sub DropBox_FileUpload(meta As Map)
    Log("Dropbox_FileUpload: "&meta)

    Dim path As String = meta.Get("path_lower")
    Log("Path: "&path)
    Dim rev As String = meta.Get("rev")
    Log("Rev: "&rev)
    Dim name As String = meta.Get("name")
    Log("Name: "&name)
    Dim size As Int = meta.Get("size")
    Log("FileSize: "&size)

    Dim server_modified As String = meta.Get("server_modified")
    Log("ClientModified: "&client_modified)
    Log("ServerModified: "&server_modified)
End Sub

Create a new file with the contents provided in the request. Should only be used for small files. Maybe up to for example 2mb... It is using ONE httputilscall to transfer the file.

B4X:

dbx.Search("","libmysql")
' Event
Sub DropBox_FileSearch(meta As Map)
    Log("Dropbox_FileSearch: "&meta)

Searches for files and folders in your dropbox.

B4X:

dbx.CreateFolder("/Export")
' Event
Sub DropBox_Createfolder(path As String,filename As String)
    Log($"DropBox_Createfolder(${path},${filename})"$)
End Sub

Create a folder at a given path.
No file or folder may exist at the path. The parent folder will be created if it does not already exist (and so on). If the parent exists it must be a folder (and the same for any ancestor). If an ancestor is a shared folder it must have write access.

B4X:

dbx.delete(("/9-patch-assets.zip")
' Event

Delete the file or folder at a given path.
If the path is a folder all its contents will be deleted too.

B4X:

Return revisions of a file

Update:: August, 20th, 2017
If you want to use Dropbox to connect to the USERS Dropbox (not YOURS) then you should look at the DropboxV2-OAuth2.zip example. It shows the way on how to get an Axccesstoken using the V2 endpoints.

The following methods are missing totally as yet: TODO

- Restore

TODO:

-

Dependencies:
- httputils2 (okHTTP)
- JSON
- RandomAcessFile
- KeyValueStore (used in example but not really needed by the class or Library)

This Class is open source and free to used and extended by anyone!

If you want to donate for my work building the class you can do it here:

Danbicky · Oct 18, 2015

Don this is awesome. Do you pretty please have an example of using this?

My idea is to knock up a simple application that allows my students to access folders I store on drop box with lesson material in such as PDF files, word, excel etc, lesson plan over the academic year, assignment schedule etc. This would allow them to catch up with work if they miss lessons etc.

Would be gratefully appreciated if you have an example I can build from.

Thanks buddy

See the Project in Post #1. Anything you need is there. You just need to call the Methods.

Just create a Folder in your Dropbox and create a ShareURL for it. Give the shareURL to all your students. They can access all the files inside this folder when using the link. You can use

B4X:

dbx.CreateSharedLink(path As String, shorturl As Boolean)

to create a sharedlink.

You students dont need to use my Class to access the files!

Maybe you should explain more in details what exactly you want to do.

PS: Welcome in our comunity!

Thanks Don,

My aim is to create a student friendly application that allows them to follow the intensive lessons delivered. I lecture in advanced electronic engineering, delivering 7 different units over the academic year. Each unit has 30 delivery sessions of material taught over the period. Ideally I would like to create an app that allows the content to become visible after the lesson has been taught. This would then allow students to recap in detail prior to completing a summative assessment.

Dropbox is a good repository and very simple for me to publish material too. Any idea's on how I go about this would be brilliant, maybe you could suggest another option if Dropbox is not the ideal solution.

Big thanks again, I am really happy to become part of this great community, only of recent have I started to dabble with B4A although I do have a wealth of programming experience coding in assembler language for microcontrollers for over 20 years.

You are delivering an app for your students which they will use?
So basically you need to get rid of which lesson a student solved. Based on this you can give the user access to the specific file for the next lesson.

The basic logic behind this you need to build by yourself. But with dropbox you have an very very powerful "toy" in your hands. You should be able to build a solution with my class and a bit of own logic (and layout to the student which lessons are available, which ones the already solved, an so on)

Danbicky said:

Like i said above i think that Dropbox IS the right solution about the repository; you (your app) is able to get specific files and to download them for the student, showing the pdf is just calling an intent after you downloaded the file...

It´s needs a bit of "logic" to handle your special needs, yes. But you surely can use Dropbox as a good place to share documents of any type and size.

If you need help on building this solution with dropbox then please create a new Thread for this issue as it will be some discusses over there for it. I will try to help you if needed.

We should use THIS thread here for any Problems using my class.

Don,

Awesome, I am heading in the right direction

Big thanks buddy, I will download your class and project and start to experiment. Good idea to start another thread based on this requirement. A big thanks for providing assistance with this, I do really think that a solution like this would help many lecturers and most importantly the students.

Kind regards

Dans

Don,

Just a quick download and complie, I get the following error:

B4A version: 5.20
Parsing code. (0.04s)
Compiling code. Error
Error compiling program.
Error description: Unknown type: anywheresoftware.b4a.http.HttpClientWrapper.HttpUriRequestWrapper
Are you missing a library reference?
Occurred on line: 76
job.GetRequest.SetContentEncoding("text/plain")
Word: setcontentencoding

I have the OkHTTP lib

Any ideas on why it is unhappy?

Thanks Dans

You need httputils libs (the ones from okhttp), http lib and okhttp

Dropbox today released the new V2 API

Some new Methods are implemented inside the V2 (compared to the beta-2). Most of them regarding Shared folders, people who are bound to a shared folder and so on... See here for more details.

I will do an update of my Class in a few weeks... For the next three weeks i probably dont have the time to do an update ...

Hi DonManfred,

I understand this code will allow me to intract wit the dropbox if it has been installed on the Android device?

So, If I want to access my files as login by username & password.. How I can do it?

Regards,

DonManfred · Nov 15, 2015

No. It communicates with DROPBOX.

Create a app in dropbox

generate access token for this app

copy the credentials. Use these credentials with the class.

Many Thanks DonManfred.

Eagerly anticipating your new Dropbox V2 class as the beta was very helpful. Do not let us down.
Thank you for being so reliable and essential driver of this forum.

I´m still working on the update.

Code:

Globals
------------
Dim dbx As DropBox

Activity_Create
-------------
dbx.Initialize(Me,"DropBox", "mytoken", False)
dbx.Upload( pathnomeDirLetture, CameraModule.fileTosend ,"/", CameraModule.fileTosend)

and then there is event ...
----------------------------

Sub DropBox_FileUpload(meta As Map)
Msgbox("Dropbox_FileUpload: "&meta,"Info")

End Sub

File UPLOAD goes ok ... and the file was send corrctly!
But event doesn't fire.

Thanks

DonManfred · Dec 11, 2015

I´ll try it again with the latest version i´m working on tomorrow.
I just tried the upload a few times and it worked all the time. Maybe as of changes in beta 2 and the final V2 it has changed.

I´ll investigate and tell the result here

Thanks a lot
