Android Question Barcode Reader

[Ian Gordon-Brown]

Hey Guys

I am a newbie. I am trying to get any barcode scanner to work. I have a Samgung Galaxy S5.
Whenever I try to install anything with the barcode reader on it, I get the following message..

B4A version: 5.50
Parsing code. (0.00s)
Compiling code. (0.94s)
Compiling layouts code. (0.08s)
Generating R file. (0.09s)
Compiling debugger engine code. (1.11s)
Compiling generated Java code. (1.64s)
Convert byte code - optimized dex. (0.79s)

Copying libraries resources (0.02s)
Signing package file (debug key). (1.53s)
ZipAlign file. (2.10s)
Installing file to device. Error
The system cannot find the file specified

Does any one know how I find out what the specified file is please?

Thanks
Ian

What project are you referring to?

Lekker Mnr

Thanks for replying. I think it is your barcode scanner.....

But I have tried 2 different scanners and both have had the same error.

Sounds like a configuration problem...

Where is the project saved?

Did you copy the Library files in the additionnal path of Library ?

 

[Johan Schoeman]

Where is the project saved?

He is referring to this project Erel. It uses 3 x jars and 1 x xml to be in the additional library folder. No other resources required

Yes I did - is there anyway I can find out which file is missing? Is there a logger on the compiler?

If you have QRCodeReaderView.jar, QRCodeReaderView.xml, android-support-annotations.jar, and jhscore.jar in your additional library folder then you have all the necessary library files that are needed for the B4A project to run. Sure you have them all?

If I look at the error log that you have posted above I would say that the project compiled successfully. It is when it installs the compiled project that the crash occurs. If you have the lib files that I have mentioned in e post above then I have no idea what file it is looking for.

OK - thanks - I did uninstall and reinstall in the hope - but did not work. I will soldier on
