So the latest news about B4a being free is totally amazing, I a lot of people must be appreciating it I know I am. That being said I think to get to the next level b4x must have a robust combination of libraries since that is one of its best features. The current libraries are advance and can do...

I have to intercept, from an Android device, an event raised from a library of the device.
I added the library with

For some reason the only DHT library that works with my module is the "simpleDHT" library in the arduino libraries running under the arduino ide. My question is how do i point B4R to this library instead of the B4R Dht library which i cannot get to work...I only get zeros..where the simpleDHT...
I'm trying to wrap a pn532 library and not sure how to handle a pointer to a byte. This method is suppose to provide the uid length when called so it needs to stay a pointer.
The original library method is the following.
bool readPassiveTargetID(uint8_t cardbaudrate, uint8_t * uid, uint8_t *...
I am now trying the chat MQTT example by Erel, but it shows (on B4A) that a library of MQTT and MQTT broker is missing.
I didn't find any MQTT library for B4A...
Does anybody know how to download the MQTT library for B4A?
Thanks in advance
I am a B4A newbie, though I have much experience writing C code for embedded systems (multi-threaded, real-time software for machine and network control and monitoring, under various RT OSes (VxWorks, embedded Linux, VRTX, self-rolled schedulers, etc, but no GUIs) and VB6 programs under...
Hi to all,
When I try to read a EAN 128 CC code, the program do this....
I use only 128 and all formats, but the result is the same.
And..... when I use all formats.... the process is sooooo slower..... the message found pass after you close the app. Killing the process too.

Bonjour, je suis nouvelle et je débute sur le logiciel B4A.
Pour un projet, nous devons recevoir des donnés envoyés de la carte Arduino au port micro-usb du téléphone Android.
Nous devons ensuite afficher ces donnés dans un tableau.
Le problème étant que je ne trouve aucun tutoriel que ce soit...
The documentation says one can obfuscate the libraries we make in B4A.
Considering that best practice is to always obfuscate everything that we release, shouldn't we always obfuscate our own libraries?
Or does an obfuscated library (for instance) make debugging more difficult somehow? Or...
This Wish springs from this topic:
Not possible to use Wait For with OkHttpResponse.StreamFinish?
It’s absolutely not the end of the world if I can’t always use Resumable Subs.
I have used this example under this thread and it's perfect! I just have one question, how could I do that the second drawer navigates to the tab as chosen? I have not figured how to call its life cycle
So we do have the following library folders:
C:\Program Files (x86)\Arduino\libraries
C:\Program Files (x86)\Anywhere Software\B4R\Libraries...
Unfortunately, in the B4x documentation https://www.b4x.com/android/documentation.html
looks like the Net - v1.77 Library is part of the default libraries.
But because the B4A IDE Library Manager does not know anything about the Net - v1.77 Library, I guess we have to google for...
it's great that you offer the Source Code for some Libraries like OkHttpUtils2 / iHttpUtils2 / HttpUtils2.
This allows us to fix annoying and unexpected issues like the fact, that the Http Utils do not give back the Http status code and, even worse, the proposed workaround is to...
