CSS compile error [Solved]

Hi All

Another question.

When I compile an APP I get the error shown in the attached screen shot. I can see that somewhere the CSS is looking for a colour to be RGBA not RGB. I am not sure if this is in the designer CSS or in the main code as CSSUtils.

At the end of the error text there is [3,53]. Does this indicate the location of the error?

Web View crash in release mode

Hello,

I found out this bug. I am using B4A version 6.0 and the device is running Android 6.

In brief: when starting a new activity I have a webview that is going to be populated with a static html page (it refers to external JS libraries).

If I place the HTML file in the asset files (loading in using B4A) I have no problem. If I place them in a subfolder inside the "Files" folders, it works perfectly if I execute the program in debug mode but it crashes when running in release mode....

Hi there,

after migrate the APP to Firebase I started to deal with something weird.

Charging for your services

There is no hard and fast rule on how to charge for programming services. I can only offer the methods that I have used in the past. Some may work for you, and some may not, but you have to have some idea of where to start.

[Objective C] Writing libraries for B4i

B4i libraries are written in Objective C. You need to use a Mac with Xcode and you need to know Objective C.
From my experience it is more difficult to write B4i libraries compared to B4A / B4J libraries.

Libraries are made of three files: library.a, library.h and library.xml.

The xml file is created automatically from the h file using the tool attached to this thread.
This is a command line tool written with B4J. You need to pass two arguments: path to the h file and path to the output...

Kiosk App

I have a requirement for a Kiosk type application that is for a dedicated 7"
tablet running Android 5.1 My programming knowledge is somewhat limited, and
this Kiosk app is a commercial application.
As the users will only have access to this application, I will require the
device (tablet) to run in "Kiosk" mode.
Essentially, this app is to operate similar to a Kindle device, where the
user has access to pre-loaded literature.
What I am looking for is someone that is willing to write the...

Again problems with 64-Bit-Integers

Hi!

I don't want to annoy you. But I'm still having big problems with the 64-bit-integers in B4A.
Please try following code:

Code:

  Sub Activity_Create(FirstTime As Boolean)
Dim q As Long
Dim q2 As Long
Dim q3 As Long

   q = 7782220156096217002
   q2 = 2
   q3 = q / q2

Log (q3)
Return
End Sub

Android "Kiosk mode" tutorial

Kiosk mode applications are applications that lock the device and do not allow the user to run any other application other than the kiosk application.

Android doesn't allow true kiosk mode without building a custom ROM.
However using the following methods you can build an application that will prevent "regular" users from playing with anything other than your application.

The application is made of two modules. The main activity and a service.
The service is configured to...

Google speech recognition (SR) not working properly anymore

I have already reported some time ago that there are problems with Google speech recognition when using Google App version 5.8 (feb.2016) or more recent. Google voice is now part of this Google App.
All three SR wrappers that can be found in the Forum (by Xverhelst, Stevel05 and Vpires) are affected.
The problems are:
- The RMS event won't fire (or only fires after the first recognistion instance), so a speech volume-indicator does not work anymore.
- The behaviour is different, e.g. the...

[SOLVED] Firebase notification subscription

Hello,

Erel's example code to send and receive notifications with Firebase.
When I change :

Code:

  fm.SubscribeToTopic("general")

Code:

  fm.SubscribeToTopic("john")

And I send with the B4J to topic general. I still receive the notification on my phone...

I thought this was like MQTT, You subscribe to a channel and recieve when something is posted to that channel?

Any ideas?

John
