Client IRC (Internet Relay Chat)
With the IRC Client complete the work started with the IRC Server. As already explained is a Basic version, to give only an idea of how it works, but it is not complete with all the commands, and does not interpret all the server commands. But it is fully functional. Limits are imposed, such as the possibility of entering only one channel at a time. But all that is missing can be inserted. The Server can be found in these two links: For B4A e for B4J

Create PDF''s on an Android devices & send them to a B4J app
There are a lot of libs about creating pdf''s. With Erel''s example (https://www.b4x.com/android/forum/threads/printing-and-pdf-creation.76712/) how to create pdf''s on Android devices (it''s a build in function of Android 4.4+) I came to the idea to use a phone/tablet to create pdf''s and send them to a B4J app. How it works: B4A -> create 100 PDF''s -> convert to byte array -> AsyncStream -> B4J -> store PDF''s as files What is it good for? - Create PDF''s for free - usage of x devices as workers to create thousands of PDF''s very fast (100 takes about 6 secs) - you can use Firebase Messaging to trigger a device (not included in the example) to retrieve data form a server-db and create PDF''s from it. Send it back to the server (via OKHeetUtils or sockets), mail it to a customer, etc.

How to disable keyboard suggestions
There are numerous threads in the forum about this, but I didn''t have much luck with them. I wanted to disable the suggestions, but they always showed. I saw one suggestion setting the field to be for email, which disabled the suggestions - but that''s clearly just a dirty workaround. This is the relevant documentation: android:inputType

jarsigner error: java.security.SignatureException: private key algorithm is not compatible
Private sign keys created with B4A v7.80 or less together with Java 8u151+ will fail with the above error message. Note that it does not affect existing keys. It is related to a change in the default key size. It is fixed for the next update of B4A. As a workaround you can switch to Java 8u144: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html Or create the key from the command line

GUI SDK Manager for newer versions of Android tools
Edit: If you are using B4A v7.8+ then a newer version of B4A Sdk Manager is preinstalled. Follow these instructions instead: https://www.b4x.com/b4a.html#installation The GUI interface of Android SDK Manager has been removed in the latest version of Android SDK. It was replaced with a command line tool named sdkmanager.bat. Most developers, including new B4A developers, still use a version which does include the GUI interface, as the B4A download page points to an older version.You can continue to use the currently installed Android tools. A custom tool named B4A SDK Manager is provided as an alternative for developers who like to upgrade

GPU overdraw
Every time your app draws a pixel on the screen, it takes time. Every time your app draws an opaque pixel to replace something that has already been drawn, it wastes time. Drawing a pixel more than once per screen refresh is called overdraw, and itâs a common problem affecting the performance of modern applications. To be efficient, every time your app refreshes the screen, it should strive to draw every changed pixel only once.
