I want to build a QR code scanner app, what can I use? And can anyone teach or send me a link/s on how to build it?
I recently had to create a QR code scanner app at work and I used Zxing library (zebra crossing). It is very easy to use and you can set the QR code scanner in a couple of minutes. I helped myself with this youtube video: https://www.youtube.com/watch?v=Fe7F4Jx7rwo
I hope this helps you!

I have implemented ZBar reader in my android application and are only using it to read QR codes. How can I limit ZBar to only detect QR codes?
I found the answer randomly an another ZBar question answer by #Sydwell
The following code solves the problem:
scanner = new ImageScanner();
// Only enable the codes your app requires
scanner.setConfig(Symbol.QRCODE, Config.ENABLE, 1);
I am looking for a tutorial that shows how to make a Qr code scanner using Zxing and android studio, there are many on there internet but all of theme use eclipse, when i try to follow the same steps in android studio it doesn't work.
Thank you all for you responses , i find that there is an easy way to do that using build.gradle
here is the link :
http://www.lihongfei.com/integrate-zxing-in-android-studio/
there is a little bug to fix because the scan works for the first time , but not for the second.
just use this function to initiate the scan
public void performScan(){
IntentIntegrator scanIntegrator = new IntentIntegrator(this);
scanIntegrator.initiateScan();
}
Try this lib.
If wraps 2 popular libraries for QR code scanning for Android: ZXing and ZBar. Which to use - is up to you!
I have compiled the Zxing core.jar and I have already added it to my Eclipse project, but I'm having trouble while trying to use the Zxing libraries I don't know where to start from. What I would like to do is to scan QR Codes directly from the device's camera. My actual app does show the camera preview in a SurfaceView, but it doesn't scan anything.
My question is how to actually scan from the camera? Without using the Zxing intent mechanism, I would like to embed Zxing directly into my project.
I'm a newbie, I would appreciate any kind of help you can provide me: code, links , etc. Thanks in advance.
The project has complete source code for Barcode Scanner in android/. You can just reference this.
Any suggestion for live stream for android.
In my app i need to broadcast live video from android on a web,some app like Qik, Justin.tv, Ustream.tv and Bambuser.
it is developed under ffmpeg,
anyone would help if there is any open source project like this,or anyone had already done it
please tell me the project name or send me a copy of the code.

Thanks.
Bambuser have opened source their version of ffmpeg that compiles on the Android. That should get you started.
see: http://bambuser.com/opensource
Best thing is SpyDroid http://code.google.com/p/spydroid-ipcamera/
It works the same as Qik
i am working on an application that needs to scan bar codes as a functionality..I have integrated all the code of zxing with my app code and now when i try to install it on my device(OS 1.6) it gives me an "INSTALL_FAILED_CPU_ABI_INCOMPATIBLE" error...
i cant use intents to use the barcode application because that will create a necessity to have zxing installed on the device..i want my application to be standalone..
Please suggest what do i do???
I did the same thing you tried to do. I did not have any such error.
Yet, the error mentions ABI, which makes me believe the problem is NDK related. (AFAIK) ZXing doesn't use native code, so you should look at the native code in you application.
