I can't seem to figure this out. When I call the following code, it hangs on the Wait For:
Dim strThisURL As String = "URL of my API"
Dim j As HttpJob
j.Initialize("" , Me)
Wait For (j) JobDone(j As HttpJob) ' Hangs Here
Dim MyDataList As List

I have read many times the request for a "Wait For" with the addition of a timeout.
This class is an attempt to implement that functionality.
It is a B4X class, in the sense that it can be used with B4A, B4J and B4i; after all it uses only one B4XView which is completely optional and almost...
I understand how to use Wait For in a B4J Server Handler. However I have no idea how to pause a server handler class waiting for some data in a SQLite database to change.
Anyone so kind to help?
I have a lot of sub routines that execute some poststrings actions with an ASP API.
So i have put the whole in a separate Code Module , like for example sending email directly via the API (its more simpler and lighter for the app) :
Sub SendAnEmail(QSTT As String, QSMESS As String...
I am trying to update an app that was based on the old Bluetooth example so may not take advantage of all the latest developments in program structure. I do not write programs for B4A very often as I mostly have to use Embedded C or design electronics. My apps are used to support our embedded...

I would like to execute some code and wait for it to complete, but I can't use Wait For sub because my application is not monolithic, so I'm trying the Timer, that is when the application ends, I start a timer for some time hoping that this may be intercepted.

Hi all, I have been hacking my way through building an app with offline maps, a database of markers and alerts as a marker comes near. It is all working fine as I post an alert to the screen with all the relevant information using ToastMessageShow.
What I want to add as an option is a verbal...
The principle behind this app is that "time is money". I have worked most of my life as a research scientist and consultant, and I can say that I have wasted a huge amount of time ($) because of poor software and data management tools.
It is not so much that the tools don't work, they do...
I developed in my app the comunication with a fiscal printer. I do it opening a socket and writing the comands in the stream.
I load the comands in a strings array and then I write them to the fiscal printer in a loop.
I have to wait the response from the fiscal printer (with the...
Ciao a tutti,
Ho sviluppato nella mia applicazione la comunicazione con un misuratore fiscale, apro un socket su questo e scrivo i vari comandi nel flusso. Ad ogni comando inviato devo però intercettare la risposta da questo per verificarne l'esito, cosa che ho gestito con i wait for.
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’m using a slightly modified OkHttpUtils. (It’s modified to be more specialized when communicating with the API on my server.)
In it there's an event _ResponseSuccess that contains this:
' Response is an OkHttpResponse
I have a mqtt class for broker connection, send messages and receive messages.
The logic that I use is:
1. Client publish message to topic: "mytopic"
2. In the other side an Script is subscribed to the topic: "mytopic"
3. As soon as the message is received, the script publishes in: "response"...
