Android Question Reading pictures from the network

[By-Cod3rs]

I want to show a photo shared on the network in the imageview1 .

Note: I viewing the current picture between two computers (two windows) .

Can you share a sample code?

 

[DonManfred]

Use okhttputils2 to download the image and show it in a ImageView.

Can you share a sample code?

You did tried to use the Forumsearch (it is working)? ;-)

It depends on the type of network. If it is a Windows shared file then you need to use SMB: https://www.b4x.com/android/forum/threads/jcifs-ng-smb-client-smb2.104560/#content

Thanks for the response erel.
but I have access to the files on my own phone.
I want to take pictures from a computer on the remote server.
can you give a hint keyword or sample code?

I want to take pictures from a computer on the remote server.

You you have a server app running on that pc which is able to do a screencapture?

It is not possible from B4A to get a Screenshot from a PC without a servercomponent.

Edit to add: Create a Server app with b4j and let it running on the PC. Connect to this server app from b4a.
The server app needs to create a Screenshot and give the result back to the requesting b4a app.

or sample code?

I never wrote such a solution. sorry

Edit to add: i don´t know if a java app can do a screencapture from the entire PC tough... Probably better to find a windows app which does a Screencapture and call this app from B4J

I'm getting an error connecting.
But I can access this file on another computer.
I get a connection error when I install it on the phone.
I would really appreciate if you help.

Which SMB Protocol you are using in your PC? SMB 1 or 2?

Which b4a library are you using? "smb" or "jcifs-ng"?

If you are using SMB2 then you need to use

this may help to find out:

Describes how to enable and disable the Server Message Block protocol (SMBv1, SMBv2, and SMBv3) in Windows client and server environments.

Thank you for the response.
We solved the problem.
Windows needs to be activated in SMB1.

Thanks.

With jcifs-ng it works with SMB 2 and 3 too

Can you give a sample code for this? I can't find anything except the library itself.

 

[DonManfred]

Can you give a sample code for this?

The Example in the librarythread is using SMB2. I do not have SMB1 activated here.

That's what I am looking for. A sample code using SMB2 to download a file from a Windows shared folder.

Download the example from the librarythread.

Please make a B4J example when you can!

 

[DonManfred]

Please make a B4J example when you can!

Check the B4A Librarythread. There is an example attached.

Should be easy to implement the same code it in B4J.
