The library is available here: www.b4x.com/android/files/DropboxSync.zip

Download this file too and extract the xml and jar from this archive and put them into the additional libs folder

Thanks a million for your fast reaction !
I got it working !, going to play with the dropbox sync now

Hi Erel,
in german we said: "to ask holes in the stomach".
it's like to bombard somebody with questions.
But my b4a Project grows quickly in the last year and is a matter of the heart.
It should be crownded with your DropboxSync Library.
My App works well wenn i navigate in my own Dropbox Apps/My_App.
I have no Problem with the up and download.
But when a Friend of mine startet the App on his Smartphone, he sees the folder My_App, but without content.
I thought the keys will handle the Permissions.
Who is my error in reasoning.
Thanks and regards
Norbert

You do realize that each user sees its own folder (which is inside his account), right?

no only on my account.
when a user say
manager.LinkAccount
he linked to my account (allow "MyEmailaddress")
i thought the keys allow the file access.
Ok, when it is an impasse, which way is it to share files on the Dropbox the other users.

sorry i mean "with other users und an App (not interactive)"

hi,

LinkAccount seems to work fine, but the
manager_AccountReady event does not react when I press Button1

I resolved it. I tried to access a file having the .db extension. I had to contact Dropbox support to change the permission (they have no permission that supports accessing .db files). Afterwards, it worked

DropboxSync allows your app to access a specific folder in the user Dropbox account. If you just want to download a file from your account then you can use the shareable link and download it with HttpUTils2.

Hi Erel!

I'm working on a project update of a sqlite database using the dropbox services but is going some errors when using the DropBox Sync Library. Here is the error:

Have you copied dropbox-sync-sdk-android.jar to the libraries folder?

Yes, I did!

Are there another version of dropbox-sync-sdk-android.jar ?

I tried to solve it another way: using the simple library application was trying to create a library to download / upload files using java package available on the dropbox site, but gives an error saying not find the com.dropbox.core package. Have you any idea?

Att. Abel

Which version of B4A are you using?

Version 2.25

I plan to get the latest version. This version 2.25 is still being enough for me to use in my projects. For now, the projects are restricted to my company.

Att. Abel

This is most probably the cause of this problem. Only B4A v3.82+ supports new SDKs that are compiled with Java 7.

Thank you Erel!

As soon as possible, i will upgrade my version of B4A.

The Sync API is now deprecated. See here for details. Are there any plans to produce a library for Dropbox API V2?

https://www.b4x.com/android/forum/threads/dropbox-is-deprecating-sync-api.53538/#content

See Docu-Site: https://www.dropbox.com/developers-preview/documentation/http#documentation

in fact i´m ready to 80-90% with the V2-lib (pure b4a using httputils)

I try to do my first app with code of this tutorial, i connect at DropBox app that i had create, but after not enter in sub Manager_AccountReady.
on log file without fiter can read this What am I doing wrong?

Make sure to choose Dropbox Sync API when you create the app. However as written in the previous post it is not recommended to create new apps based on this API.
