Watch the b4x Video Tutorials with interactive zoom
If you''re having problems with the resolution, or your age ( :( ) and you see the code too small ,try to use this tricky feature in VLC Player called "interactive zoom". You can see all code much clearer and also you can jump immediately to other section of the screen such as the log output area etc.

B4XEncryption .net DLL class library
I recently had the need to send encrypted data from my B4A/B4J/B4i apps to a .net web service. Because the B4XEncryption library works in all the B4X environments, I wanted a way to decrypt and encrypt data in the same way as the B4XEncryption libraries do.

I''ve created an ABMaterial WebApp to show the documentation for the libraries. Everyone who created a library for B4A, B4i or B4J can upload their .xml file to the WebApp and everyone can consult it. One can re-upload a new version for a library if needed.

Drawing with B4XCanvas [B4X] [XUI]
B4XCanvas is the cross platform version of Canvas. Steps to using B4XCanvas: 1. Initialize and pass the target view. In most cases it will be a Panel (or Pane). It must be a Pane in B4J. 2. Make the drawings. 3. Call Invalidate to commit the drawings. 4. If the target view is resized then you should call B4XCanvas.Resize. This is more relevant in B4J and B4i as the activity is recreated in B4A when the screen size changes. 5. B4XCanvas.CreateBitmap returns the drawings bitmap.

FTP Server code update for multi-network card hosts [B4X]
(This code will work with B4A and B4J) This relates to the FTP Server code posted here (https://www.b4x.com/android/forum/t...d-with-socket-and-asyncstreams.74320/#content). @Sergio83 discovered an issue with the FTP server when it is deployed in a machine that has multiple active network cards (see https://www.b4x.com/android/forum/threads/ip-address-confusing-when-upload-file-with-ftp.84816/). In such an environment, it can happen that the FTPDataConnection may be assigned a different IP address than the FTPClient command connection, which will cause connection issues (as per the post linked above). With @Sergio83''s help in testing the development and refining of a solution and @Erel''s help in using Reflection vs JavaObject, the following code changes will allow for the proper handling of client connections
