B4A Library ABZxing Barcode reader

This is a library to read barcodes. It uses the Zxing app to do the scanning. If the Zxing app is not installed, the user is redirected to the Android market to download the app.

Functions:

ABGetBarcode (eventName as String, mode as String)

Starts the barcode scanner. The barcode is returned in the BarcodeFound event or the Canceled event

Params:
eventName (String): name of the ABBarcode object (lowercase!)
mode (String):
"" for everything
"QR_CODE_TYPES" for QR codes
"PRODUCT_CODE_TYPES" for UPC_A,UPC_E,EAN_8,EAN_13
"ONE_D_CODE_TYPES" for UPC_A,UPC_E,EAN_8,EAN_13,CODE_39,CODE_93,CODE_128

Example:

Sub Button1_Click
    myABBarcode.ABBarcodeGet("myABBarcode", "QR_CODE_TYPES")
End Sub

Sub myABBarcode_BarcodeFound(barCode as String, formatName as String)
    msgbox(barCode, "")
End Sub

Sub myABBarcode_Canceled
    msgbox("Canceled","")
End Sub

Google Googles

I have just tried with this too and it also works. It is very fast and works with both standard bardcodes and QR Codes. I have not tried it with any pictures.

Why ask? Why not just try it for yourself! It seems to respond to the correct intents.

Did you install the ABZxing library?

 

[domv]

Install Library -- can't find it

Sorry but I looked for the library in the IDE and couldn't find it.

thanks

 

[NJDude]

Some libraries must be downloaded and installed, THIS link has all the 3rd party libraries you might need.

 

[domv]

Worked great, thanks

ShopSavvy

I have ShopSavvy Installed so whenever I try to scan something, ShopSavvy starts and I don't want that. What can I do? I have tried to uninstall ShopSavvy but it's like a virus. Won't uninstall.

ZXing

Hi, finally got rid of ShopSavvy and now I just have Zxing.
Anybody know of some FREE TTF for creating bar codes?

LOOK

Free Barcode Font - Code 39 - Not a demo, COMPLETELY free

Option to use QuickMark as default instead of ZXing

This library is awesome!

Just a request. When a barcode scanner is not available it automatically points you to download ZXing barcode scanner. Is there any way I can select QuickMark as the default barcode scanner to download instead? Quickmark is better for my purposes.

Thanks.

scan question

Hello,

i added this to a program i`m making and when you push scan button goes to scanner. When you scan something it says Found Product and then the screen close and goes back to my program. But it seems that its going to Sub Activity_Create and the activity loaded again from the beginning and not resume from there it was...

Is there any way that i can scan something and then my program resume from there it was???

thanks in advance

I sporadically have the same problem with Activity_Create being called when returning from the Scan call. I would say it does this 10% of the time. I thought at first it was related to the amount of time it took to scan, but I can set it down for 5 minutes and come back and scan and it will return to my app with no activity_create being called, other times it will occur even if I scan immediately ... not sure why.

For now, I use File to create a file before a scan starts and then delete that file after the scan result comes back good. I modified activity_create to check for the existence of this file and to display an error and redo the scan. It would be ideal if we could store the scan results in a file before returning, and read that if activity_create gets called (to avoid a rescan). My experience is that the scan results are lost when activity_create get called on the return, is that yours?

thanks for the answer.
Its is doing that 100% of the times i scan...
and yes, the scan results are lost when activity create called...

Have you tested using other devices? Also, are you using the demo program (ABBarcodeTest.zip) to test?

I haven't done much with services, but I'm about to try making the scan intent call to zxing using that (if its possible). I believe that is frowned upon though.

 

[Evadman]

As a note, the documentation in the first post and in the documentation here state the method is 'ABBarcodeGet', when it is actually 'ABGetBarcode'. Awesome job on the library!

Library Extension to create QR Code

Is it possible for the ABZxing library written by Alain Bailleul to be extended to allow for the creation of QR Codes locally? Or is there some other library/code interface that could be used with B4A to generate a QR Code in the application? The ZXing Project seems to indicate that their code has the capability. Since I don't know Java, then what may be possible is beyond my understanding.

Currently, I'm using Google charts to create a QR Code for in-app display, but when there is no data connection, then there is no QR Code.

Is there any way to translate the text displayed by ABZxing?
