Work with Google Drive

[Kiese]

Thanks for the tip @Erel, it might be, so. I am using 3.81. I do get the warning "was created with a newer version of B4A". Most of the time it still works so I ignore it but that might be causing it. Guess I'll update and see how it plays out !

Hi all,

I published the source code now because I've not enough time to further development this project. Maybe anyone can optimize the lib for a better usage.

Hi Davfla,

Thank you for lib. I have log in into google developer console, how to get access key and secret key?

 

[rafaelmotaquintana]

I got the ClientID and secret code, using option 'other', because android option won't give me a secret code.
Connection is successful, but I can't create a folder, I have this in the log

Asking for authorization from user.
Authorization granted by user.
No Access token
Send a request for a new Access token
New Token was created
Token is not correct. Try to refresh.
Error Message : Forbidden
Refresh Token
Create Folder
Forbidden
Refresh token done

What I'm doing wrong?

SOLVED
Had to enable the drive api in google page.
Now my problem is that it only works in release mode, in debug always gives me this:

An error has ocurred in sub:
java.lang.RuntimeException:
Object should first be initialized (activity).
Did you forget to call
Activity.LoadLayout?

b4A version is 5.80

Hello. I am testing in and cheap tablet. It has no google play nor google drive installed.
The command

 GoogleDrive.Initialize(Me, "Drive", clientId, clientSecret)

does not throw any error
so after the command

GoogleDrive.ConnectToDrive

I get this message and the program cancels

An error has occurred in sub:
java.lang.RuntimeException: Object should first be initialized (Activity).
Did you forget to call Activity LoadLayout?
Continue?

My question is, How do I know if the device is capable of use this library (the same program runs fine in another device).

Hi, I'm trying to compile the sample with my credentials but it raises an error

Compiling generated Java code.    Error
Cannot find: C:\Program Files\Anywhere Software\Basic4android\libraries\webviewxtended.jar

I'm using B4A V6.00 and WebViewExtras Library is 1.42.

Thanks in advance.

 

[Erel]

Have you copied the jar file to the additional libraries folder?

 

[Descartex]

Yes, libGoogleDrive.jar is there

 

[Erel]

Based on the error message this library depends on WebViewXtended library: https://www.b4x.com/android/forum/threads/little-webview-extension-v1-20.13705/#content

 

[Descartex]

Hi all, can someone provide a step by step on howto obtain client I'd and secret I'd to use this library?, I'm trying, but with no success on Google console. Thanks a lot.

Go to Credentials-> Create -> Oauth ID
Then select Other, input a name for the credential such as "Google Drive Sample App" or something else and click on Create, it raises the ClientId and SecretID.

Thanks, @Erel, now it works properly

I tred this code to retrived the list of files in Google Drive, but don't works:

Log(clsDrive.ShowTheFileList)

Hi Davfla,

Thank you for lib. I can upload the files in the root directory of google drive, but can not upload files in sub directories.
I am using the field DriveFolder
clsDrive.UploadFile ("xxxxxxx", "xxxxxxx", "xxxxxx", "drivedir", "")

Maurizio

I am having that problem too. The files cannot be uploaded into sub folders. This way, I cannot share the entire content to the public.

Hi Davfla.
Thank you for sharing your time and your efforts.
Are there any "Activity Events/clsDrive.DeleteFile" to delete a file on the remote Google Drive, if the ID is known ??
According to documents: https://developers.google.com/drive/v2/reference/files/delete

Someone Look like this :

DELETE https://www.googleapis.com/drive/v2/files/0B5LqWVCwfFwvdmFNejNnMkhkajg?key={YOUR_API_KEY}
GET https://www.googleapis.com/drive/v2/files?key={YOUR_API_KEY}
POST https://www.googleapis.com/drive/v2/files/0B5LqWVCwfFwveEo0MGh2eUdTams/copy?key={YOUR_API_KEY}
POST https://www.googleapis.com/drive/v2/files/0B5LqWVCwfFwveEo0MGh2eUdTams/trash?key={YOUR_API_KEY}

1. Upload in a folder not work. Folder create is ok, but file not uploaded in the folder "Temp",
what is wrong ?
googleDrive.UploadFile(datei, File.DirRootExternal&"/"&driveBackupPath, datei, "Temp",GD_Datei_ID)

2. Upload a zipped file "Test.zip" > 53MB in root give a Memory Error,
20MB was ok.
For this reason I would like to upload the individual files to a folder.

Hi DAVFLA,
Thank's for sharing your work.
Unfortunately for me the source does not work, uploaded files are always 'untitled' and I do not know why.
However, to speed up the search without downloading the complete list of the files(Especially if the file does not exist), I developed this sub that seems to work.
to be called instead of 'ShowTheFileList'.

' ##### This is the Sub Added #####
Sub SearchTheFileList
   ProgressDia(True, strTEXT_WAIT_Filelist)
   FileListResult = ""
  
   GetFileList.Initialize(Me) : GetFileList.Tag = "GetFileList"
   Log(DriveListLink & "?access_token=" & myAccessToken & "&q=trashed+%3D+false+and+title%3D%27"& mySearchingFilename &"%27&maxResults=" & MaxResults)
   GetFileList.Download(DriveListLink & "?access_token=" & myAccessToken & "&q=trashed+%3D+false+and+title%3D%27"& mySearchingFilename &"%27&maxResults=" & MaxResults)
End Sub
'##########################
'Searching on Google Drive for a file with the filename. If founded the function returns the file ID, otherwise it returns ""
'This can need a lot of time if many files storage on Google Drive.
'If more than one file with the same filename found, the first result will return
'
'Event : FileFound(ID as String)
Sub SearchForFileID(Filename As String)
   IsSearchingFilename = True
   mySearchingFilename = Filename
'   ShowTheFileList
   SearchTheFileList '<- CALL
End Sub

Let me know if it works and if you insert it in the library.

Has anyone ever managed to upload a file to a folder on GoogleDrive?

 

[Paulsche]

Error by upload a file with 53MB.
java.lang.OutOfMemoryError: Failed to allocate a 67092748 byte allocation with 16777216 free bytes and 59MB until OOM

What is the problem ?
A file with 20 MB is uploaded without problems?

 

[DonManfred]

What is the problem ?

Seems like the lib does load the complete file into memory
