Elements in multi-dimensional lists

What's the easiest way, in B4J, to refer to an element in a nested list?

So specifically, if you had

List1.AddAll( Array As String( "one", "two", "four" ) )
List1.AddAll( Array As String( "seventeen", "thirteen", "five" ) )
List1.AddAll( Array As String( "hundred", "eight", "zero" ) )


, and you wanted to obtain the "thirteen" at ( 1, 1 ),

is there a simple way to do that, with B4J syntax?

Also, if you wanted to replace the element at (1,1), what is the simplest way to to that?...

AppUpdating - automate apps updating from a webserver

Note: version 1.25 breaks existing code so, please, read changelog in post #60 below.

Hi all,

this is my first contributing lib to this great NG.
How do I dare to publish such a low-grade stuff in an area where generally you may find real masterpieces of programming? Well, to be honest, I hope in your help to upgrade my work...

Compile non-ui, but don't run it yet

Building a headless app that I will wrap into an exe and run as a service, all is well compiling in debug mode, but when switching to release I want to compile to .jar but NOT run it. Workaround is to use task manage to kill it, which gets complicated if you have more than 1 java app running, so is there a way to compile in release without running?

SOLVED: Send UDP from Genymotion emulator to desktop

I tried to send udp with string data from B4A on Genymotion emulator to desktop B4J app. UDP packets don't arrive in B4j app.
I managed to send udp from desktop B4J app to desktop B4J app, and from one GM emulator to another.
I tried to use wi-fi IP, VirtualBoxNet IP for desktop host, 10.0.2.2, 10.0.3.2, 192.168.56.1 - doesn't work.
I tried app "UDP sender" from Google Play from emulator and real device - doesn't work.

I found my solution for my problem: firewall settings

asyncstream close requirement

when i close the application from main activity i have the following question regarding the simplified code below.

1) do i need to close the asyncstream specifically when i stop the logger service?

i've read you should not reuse an asyncstream. however, since it is in the starter service (and assuming the starter service hasn't been killed) can i just initialize it again as shown?

Code:

[IoT][ESP8266]GPIOs & total control with B4J/B4A/HttpUtils & ESP8266 Basic

What is a ESP8266?

It's a small Basic programmabe microcontroller with Wifi, TCP/IP stack plus server, GPIO's and... it's unbelievable cheap. For about 3€ you get it as a bulk version which you have to solder. For 5 more you get this one with a micro usb UART adapter and a voltage converter (5V will kill it).

Hosting Service & Control Panel Poll

I'm doing a poll to see if a planned project would be worth it.

Q: How many would purchase B4J "hosting" service?
Q: How much would you pay for the service?

Q: If you just needed a control panel (that would allow the easy creation of B4J web apps), would you purchase one?
Q: How much would you pay for a control panel?

Msgbox and Service

Hi

I have used the Starter service to do a simple counter which calls a sub in the Main to display the number.

In the Main I have a button_click sub which shows a MsgBox.

When the Msgbox appears, the counter stops. I thought Starter service allows background task to take place and I was expecting the counter to continue even when the Msgbox appears.

How do I make the counter continues even when the msgbox appears?

I have attached a zip file.

Thanks.

updpacket not received at specified port...bug?

I have a UDPsocket initialized on port 56000, I send a udpPacket initialized with port=56142. Wireshark confirms that the srcport=56000 and dstport=56142 as expected. The receiving end has UDPsockets on 56000 and 56142. The packet is received on the 56000 socket, not the 56142. Is this a bug, or a user error?

This Library can be used to connect your Device to a MySQL database. The Library use a direct connection to the MySQL databaseserver.

Requisites: The Database must be accessible from "outside"
DisAdvantages: Due to the app needs the Databasecredentials (including username and password). There Credentials must be included in your App. I suggest using this Library only for private or company intern use.

The path to the file when using the soft emulator

During initialization drawing or reading a text file on the emulator, I have problems. I suspect that when debugging and testing on an soft emulator, the standard DIR File.DirAssets or File.DirInternal - give errors. So I think in the code is necessary temporarily to print a different path. If I'm right do you can tell me how to describe the standard path to the files when use on the emulator. For me to use the emulator is very convenient so do not need me to discourage use of the emulator
