Barcode scanner in android?

One of the biggest advantages of the Android platform is that you can leverage other apps to provide increased usefulness for yours without a ton of work. In essence yes you could rewrite the bar-code app, but a lot of people will ask why would you want to reinvent the wheel? Now it is true that the zxing process is open source so you can look at their entire program, however I found it more effective to just leverage what was already there If you place a check in the program to see if the system can handle the action, you can recommend people get the bar-code scanner to unlock that functionality This process is encouraged by the folks at Google.

However, as always, you can always try to rewrite it from scratch.

Thanks @pyrodante. For the quick reply and sorry for my bad english. I have tried to load the image from sd card and then decode.

Actually its working fine. Instead can I read the image that its captured by camera and decode it? I am lacking in this part only.

Please provide any links or steps to continue the process. – lingesh Jul 27 at 4:26 Here is a good start stackoverflow. Com/questions/2050263/… – Pyrodante Jul 27 at 16:04 Thanks for referring this link @Pyrodante.

I need to implement a stand-alone app. So I have to do via intents. I saw the code in \android\ directory in zxing src I downloaded.

I compiled the barcode scanning app source code and tested it in device. Its working fine. Question thats what I want to ask is, for invoking the CaptureActivity in src, I need the other activities?

How can I seperate the scanning part only to implement the same using the zxing libraries. Or do I need the whole source files in the /android/ directory to build a scanning module? Thanks for helping :) – lingesh Jul 28 at 8:29.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
