- Project update: Added a host of files including the major CodeCaptureActivity 
that will scan and interpret a QRCode. On the other end, my code now takes a 
Find's GUID, Time of creation, Name, Description, Longitude and Latitude 
information and encodes it as a QRCode. I have attached screenshots of a QRCode 
created by the plugin and also a screenshot of the POSIT barcode viewfinder in 
action. 

- At this point, working on the logic to follow this flow:
  - User creates find as normal, background barcode identified by guid is saved
  - User is able to pull up barcode when needed
  - Another user can focus his/her posit app on the barcode created by first user
    and add the find without having to re-enter. 

- Will also need to watch for updating barcodes when the find is edited or 
deleted.

Completed the coding to:
- create a QRcode from a Find
- decode a QRcode (created in POSIT) into a Find and allow for saving. 

Tested QRcode apk on my Samsung Galaxy Tablet as well. Pictures below.

I have also attached my exported application (positx.apk) for anyone interested 
in seeing how it works. 

Test Script (For creating a Find + QRcode)
- Open POSIT
- Choose Add Find
- Enter Name and Description
- Save 
Expected Result: A QRcode will flash across the screen showing that the QRcode 
has been created. 

Test Script (For viewing a Find + QRcode)
- Open POSIT
- Choose View Finds
- Scroll down to the Find you just created (or any other find for that matter, 
will explain this)
- Open it up and select View Barcode
Expected Result: The QRcode will show up in full screen

Test Script (For decoding QRcode + making Find)
- Open POSIT
- Choose Add Find
- Go into the Options menu on this view and choose "Scan Barcode"
- Holding the device horizontally (for best performance), focus the QRcode (ive 
attached one for a test) and wait for the viewfinder to decode it
Expected Result: The details of the Find will be added to the Add Find fields 
and you can save it. Of course, the QRcode will flash across the screen 

N.B: At this point, every Find that has ever been created in POSIT can be 
instantly translated to a QRcode using the View Barcode button. This would sort 
of let other POSIT devices save information instantly. Another thing is that 
the barcode is NOT stored on the device, just created when needed based on its 
information. 

Will still need to fix up documentation, further bug checking and any other 
things that may be suggested.

Just found out about Droid@Screen that lets you record your android screen on a 
PC so did a video demo of my barcode functionality!

Hi Yemi,

This all looks good. I'm going to test the patch now.  It would great if you 
could copy the write ups you've posted, with the screenshots and video, and 
post on the Wiki as documentation for the Plugin.   Here's where to post it:  
http://code.google.com/p/posit-mobile/wiki/PositxArchitecture

Works great. I was able to create barcodes from existing finds and able to 
create a new find from the barcode posted on the web.   

One possible issue:  When I scan a non-Posit barcode, the app reports "The 
application POSITx has stopped unexpectedly. Please try again."  And it causes 
a "force close". When you force close, it just goes back to PositMain and the 
app continues running without issue.  So i think it would be better to detect 
the invalid (non-Find) barcode here and just report it as invalid and let the 
user continue.  

Also, I see that the new plugin folder, plugin.barcode, contains all (or 
mostly) ZXing source code. I think it would be better to package this as a 
library (jar file) and add it to the library rather than including the source 
code.  Can that be done?

- Ive added my plugin to the POSITArchitecture in the Wiki: 
http://code.google.com/p/posit-mobile/wiki/BarcodePlugin

- Ive also fixed the non-Posit barcode issue and uploaded a new patch for that

- I will work on refactoring the code so its connected to a Zxing jar. There 
are actually a bunch of files i took from the zxing source code and re-edited 
in compliance with their license because the zxing functionality was too bogus 
for my purposes. but ill see if i can fix it
