Android Question b4x bar code scanner plus additional library

[Pepebis]

Dear all ,
I'm trying to incorporate a bar code scanner from this example https://www.b4x.com/android/forum/threads/b4x-b4xpages-barcode-reader.120417/ with udp library. Separratly both of them are working just fine. Problem occurs when I'm combining them.
First is that error :

HttpUtils2Service is declared twice. You should either remove the library reference or the code module.

Please see attached file.
When another activity is being loaded problem is showing.
Another problem is with Toast message, this is not working with that combination.

Any suggestions?

what is MkWiFiUDP? I can not find this library

The project you uploaded is not using any httputils library or classes. Neither the module or the library!?

 

[Pepebis]

That library is establishing udp communication with wifi modules. I don't know if that lib is using httputils . I guess not.

1. Where can i find this library?
2. The project you uploaded is NOT using any httputils.

I guess not.

i guess yes

library is attached in shared file

 

[Pepebis]

ok. you were right . in xml file

<dependsOn includesSingletonModules="true">httputils2</dependsOn>

what should i do ?

 

[DonManfred]

remove that line from xml

PS: Edit to add. I would delete this library as it looks like it is internal using a httputils2 service module which is a mistake

Ask the author to fix that

 

[DonManfred]

The library has the module included. BAD CODE
