I am proud to present you my new App... for Windows-PC and Android Version (B4J and B4A)... meet@point Is an example - how to create a Video Conference Application... is using MQTT technology... you can use it from Android or Windows PC... you can communicate with Video (webcam, or android camera) - max 5 users (for video - because of layout)... with audio (press to talk or 2-way using headset / because not using a "noise/echo cancellation" technique)... and ofcourse you can communicate with text... Enabling 2-way audio is possible if you have the source-code... You can say that is a viber-like, skype-like, teams-like, messenger-like app... but it isn't... it is meet@point ! It is very simple and easy to learn how will do it... easy...

Wordle is a nice 5-letter game which immediately results in brain-storming that involves arranging letters in the correct place. Therefore, I thought it is worth a try in b4a. All game graphics were made of scratch. You should guess the word and write it in the row. The app will show which letters are wrong (red), which one is correct in correct place(green) , and which one is correct but in the wrong place (gray). The word which is not found will shake the row. The animation is still primitive Watch here. (sorry, the Youtube link can't be shared here)

This is one of my first programs created in B4A. It's a game similar to Ruzzle but more fun. You could have challenged someone else by connecting with Bluetooth

i've spent a lot of time scanning neighborhoods, hospitals, athletic facilities and municipal buildings for bluetooth ble devices. i know who has giant tv's (and whether they're on or not), clothes washers, smart watches, hp printers, soil ph testers, nanny cams, door cams, earpods, "find me" tags, windows laptops, sleep monitors, not to mention the array of ios devices blanketing the world with their continuity broadcasts. but it's time to move on. before archiving my research into ble devices, i wanted to mention some (cheap) fun devices which crossed my desk: thermometers and personal medical/sports devices, among which the so-called smartring(drgottjr recommended). some of the devices are pictured below, and their measurements...

There was a time when NXP's Mifare Classic NFC tags were the go-to card for, among others, bus, metro and train passes, hotel keys, club memberships, etc. They offered security of a sort which required keys to access the tag's memory. Due to discovered security flaws, however, its day has mostly passed. Nevertheless, reading from and writing to Mifare Classic is an interesting exercise, and we still see some interest here on the forum from time to time. The most interesting aspect of the tag is its ability to perform simple arithmetic. In other words, the tag contains a program. Gbuspass is a proof of concept since I don't actually run a bus company, nor should you try to use any tag initialized by the app to ride a bus. You need a...

La presente aplicación ha sido desarrollada para el control de los animales en una finca de engorde de ganado.

El sistema de producción de engorde de ganado, se basa en la compra de animales con un peso promedio de unos 300 kilogramos, para llevar a un peso final cercano a los 500 kilogramos. Durante el proceso de producción, el ganadero realiza diversas actividades de manera frecuente: - Pesa los animales con el fin de determinar las ganancias de peso - Realiza distintos controles sanitarios, entre ellos, las vacunaciones. - En algunas ocasiones, realiza registros...

B-POS is a fairly simple point of sale app that's designed to run on a tablet and enable the sale of merchandise at events. We're a member supported club, and this is an important source of revenue for us. It's intended to be used with a standalone card reader, like a Square or MyPOS device, and can link to a Bluetooth ESC/POS printer to produce receipts. This is a work in progress (particularly, I've only tested it on the Galaxy Tab A9 that I'll be using for an event later this month; I hope to improve that later). Also, I'll be working on more integrations, including using the postback options to fully integrate it into our PrestaShop online store. Key features Grid display of products with images and prices Automatic totalling of...

Hi all, I have just published on Hackaday a new electronics device to find Center of Gravity onRC planes. Link is here : https://hackaday.io/project/202834-rc-plane-center-of-gravity-finder Of course an Android App is there to display this kind of information : It's based on two digital scales controlled by an ESP32 MCU. It works with big or small planes !

The application allows you to read such a file by clicking on its name in the phone's file manager. Different managers return URIs according to their methods. The managers I have give the following results: content://com.alphainventor.filemanager.fileprovider/root/storage/emulated/0/Download/my.ged content://com.cxinventor.file.explorer.fileprovider/root/storage/emulated/0/Download/my.ged content://com.android.externalstorage.documents/document/primary%3ADownload%2Fmy.ged content://com.amaze.filemanager/storage_root/storage/emulated/0/Download/my.ged To extract the values of the folder and file names, you need to normalize the URI: Dim folder,filename As String Dim n As Int uri=Regex.Replace("%20", uri, " ")...
