From https://developer.android.com/training/permissions/requesting.html#perm-check
If the device is running Android 6.0 or higher, and your app's target SDK is 23 or higher: The app has to list the permissions in the manifest, and it must request each dangerous permission it needs while the app is running.
CAMERA is a "dangerous" permission. I am uncertain, but my impression is that the intent, the bundled version of zxing should be making that requestPermissions() to prompt the user to allow access. Since this not happening the only way you can use this module appears to go into "Settings" and give the app explicit access to the camera.
I haven't used Java in a long time, but if somebody can point me in the right direction I'd be happy to attempt to fix this. Thanks!
Overlay looks good on Android however on iOS I'm getting this:
With this code:
var overlay = Ti.UI.createView({
backgroundColor: 'transparent',
top: 0, left: 0, borderColor:'white', borderWidth:2,
width:'100%', height:'100%'
});
var cancelButton = Ti.UI.createButton({
title: 'Cancel', textAlign: 'center',
color: '#000', backgroundColor: '#fff', style: 0,
font: { fontWeight: 'bold', fontSize: 16 },
borderColor: '#000', borderRadius: 2, borderWidth: 0,
opacity: 0.5,
width: 220,
height: 40,
bottom: 20
});
cancelButton.addEventListener('click', function () {
Barcode.cancel();
});
overlay.add(cancelButton);
It should take up the entire screen I would think unless I missed something... thoughts? Thanks!
Hi,
using 2.3.0 of module in sdk3.5.1.GA shows on home screen of android "Barcode Scanner" (text from modules/../res/values/strings.xml) and not my name from tiapp.xml. If I have more then one apps with scanner all apps have this wrong name. In system configuration I can see under apps the right name.
With the upgrade to iOS 9 I am no longer able to compile my app, because this module doesn't have support for the new architectures.
Cancel button not working in both cases on ios. Either i use overlay and add my own custom cancel button or use showCancel property with true value. Both cases not able to close Barcode scan view. Working just on simulator but not on device tested on iPod having iOS 8.3. I tested with latest code and module 1.10.0. As @hansemannn respond on issue #19.
Hey guys, please try #32 which should resolve this issue, too.
On iOS i have no problem, i only ask the permission for the camera
if (Ti.Media.hasCameraPermissions()) {
openQrcode();
} else {
Ti.Media.requestCameraPermissions(function(e) {
if (e.success) {
openQrcode();
} else {
var tempmessage = "Hai negato l'accesso alla fotocamera del dispositivo inibendone la possibilità di scansionare i QR code.\n\n";
if (isAndroid) {
tempmessage += "Naviga in Impostazioni / App / " + Ti.App.name + " / Autorizzazioni e consenti l'accesso alla fotocamera.";
} else {
tempmessage += "Naviga in Impostazioni / Privacy / Fotocamera / " + Ti.App.name + " e consenti l'accesso alla fotocamera.";
}
var alertDialog = Ti.UI.createAlertDialog({
title: "Attenzione",
message: tempmessage,
buttonNames: ["Ok"]
});
alertDialog.show();
}
});
}
function openQrcode() {
Barcode.capture({
animate: false,
overlay: overlayQrcode,
showCancel: false,
showRectangle: true,
keepOpen: false,
acceptedFormats: [
Barcode.FORMAT_QR_CODE
]
});
}
But now on Android i think i have some problems with the permission... For Android i use the same code above, plus this on the tiapp.xml
<android xmlns:android="http://schemas.android.com/apk/res/android">
<manifest>
<application android:theme="@style/Theme.AppCompat.Translucent.NoTitleBar.Fullscreen"/>
<application android:debuggable="false"/>
<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="23"/>
<uses-permission android:name="android.permission.CAMERA"/>
</manifest>
</android>
On Android , when i have to open the camera, two permission requests are displayed
After the permissions are accepted, the function openQrcode() is called, and the app crashes.
Whilte scanning of QR code is very fast and solid, the results for Data Matrix scans is unfortunately very unreliable. Some codes work, others not at all, especially with surrounding dark background. Does anyone face the same problem and has a proper solution? Tested with iOS.
I'm having errors trying to use the barcode scanner v. 3.0.0
I'm using Titanium 6.0.2.GA, node 4.6.2 and targeting Android SDK API: 23
Is this a known issue? anything i could try to make it work?

How can I support both orientations for Android app? As current version only scans barcode in landscape mode. What changes I have to make to work it in both orientations. I want it to relayout scan view when user change it's device orientation. Can somebody help me out how to achieve this?
I got some errors connected with not found BookmarkColumns symbol:

When i tap on "Scan Code", the app crashes. Without a log.
If i tap "Scan Image from Gallery", and use an image with barcode/qrcode, the module seems to correctly recognize both.
there is a method to customize the dimension of rectangle in overlay during barcode scanning?
now the dimension if the screen in not so higher is good, but with big monitor (S5,S6,NEXUS5) the rectangle is too little...
thank you
When the reader is activated , the camera does not focus properly clearly, it is not crisp as it should be to activate the camera. For example using Barcode Scanner does work fine, show up correctly! but for some reason with Ti.Barcode no. Any Idea?
I am using titanium 5.1.1.GA
On android 5.1.1
Thanks!.
Hi.
I got it working on my app and everything is wonderfully fine, all barcodes are read quickly, with the exception of CODE_128, 128C to be more precise, that unfortunately is the only one I really needed to work within this app I'm building.
This is the only Ti barcode module I was able to get working. So, I'm really out of options here.
There is something that can be done to make it work right with CODE 128?
Thank you.
I think the module use the version 1.7 of zxing. Maybe it will be good to update the library ?

Hello friends,
First of all thank you for the library, it's very useful. And I was happy with it until I tried to set Barcode.allowInstructions = false;. First time it works great, instructions are not showing and the scanner works as expected. But after second scan attempt the app crashes with the following error.
Here is the stack trace (android):

Environment:
OS Ubuntu 14.04
Titanium Studio, build: 3.4.1.201410281727
Titanium SDK 3.5.0.GA
Ti.barcode 2.3.5
Tested on devices LG-D690 (android 4.4.2) and Samsung GT-S7562 (android 4.0.4).
Thank you in advance
I would like to know if it's possible to start scanning inside my tabbed app.
Actually, the camera launch in full screen, and bars are disappearing :/
I see there is "SurfaceView" in android that allow to do this, do you think it's hard to implement ?
Thanks for the answer.
I'm testing the module on iOS. It works very well (to well). I have enabled only the Barcode.FORMAT_QR_CODE.
In fact, very often if i start scanning with the camera in front of a qrcode, this is recognized immediately, not even allowing the view-overlay to open (or the view-overlay opens for a few milliseconds).
Would not it be useful to add a delay (in milliseconds?) before activating the scan? That is, open the camera, but enable scanning after the set delay.
Thank you
Why not update this module to the new version of zxing?
It have a lot of new features and bug fixes!
Would like that.
Hello. Can you please tell me how to install this module within my app? I followed the link you gave for the titanium module installation but it isnt getting installed.
Sorry for a simple query.
Hello everybody!
Is possible to use ti.barcode module with the SDK 5.1.2 Titanium version?
Thanks in advance.
Best regards,
Mirco
The project description "QR and Barcode Scanner " is missleading.
It's not possible to scan 1d Barcodes with this module,
because "OneDMode" ist set to NO.
Only minor changes are required to enable 1d Barcode scanning.
TiBarcodeModule.mm->line 233 change OneDMode:NO to OneDMode: YES
ZXingWidgetController.m->line 498 if (oneDMode) to if (NO)
The first time you use the bar code scan feature instead of seeing the camera image a black screen is shown.
Pressing back seems to not do anything, putting the app in background and then bring forward still showed the black screen, closing the app and reopening still shows the black screen when scan bar code is selected again. I can’t be sure but I think rotating the screen or swiping down the top menu when the black screen was shown caused it to then show the what’s “New in version 4.0:” screen for the bar code scanner. Once you press DONE button at the bottom the camera image is shown and you can scan. After then selecting scan code always brings up the camera. So it looks like the display of the scanner “whats new” screen is causing issues.
Hello,
I can compile the app (linking of ti.barcode successful), but at runtime comes:

This issue kills the app.
I am using the Barcode.parse method to parse QR-Codes on Image (receipts) from the gallery. Most times I get no result from the parsing. Can you please tell me how to improve the results? Does it maybe depend on the image size or the position of the QR-Code?
try { Barcode.parse({ image: blob, acceptedFormats: [ Barcode.FORMAT_QR_CODE ] }); } catch(e) { Ti.API.info(e); } }
When pressing the Android menu button on an Android device, the host app crashes. allowMenu seems to have no effect.
In iOS, the overlay view, no matter what you do, is not able to be formatted for width and other view layout properties. No matter what you do, the view (via createView) always aligns upper left and it is impossible to have it's width or height fill the parent window. Everything in this regard works as expected in Android.
hi man now i have a problem while using the module in ios when i run the module 1.9.0 on titanium sdk 3.5.0 RC it give me this bug
[ERROR] : ** BUILD FAILED **
[ERROR] : The following build commands failed:
[ERROR] : Ld build/Debug-iphoneos/qr\ reader.app/qr\ reader normal armv7
[ERROR] : (1 failure)
can u help me to fix this bug
Any plans to include PDF417 support to scan id's? Thanks so much
@hansemannn On latest iOS version, we're seeing the camera overlay view randomly disappear after a period of time if you leave the scanner open but don't scan a code.
Sometimes 5 seconds after opening, other times up to a minute, very random. Thought it might have been to do with touch or orientation, but have been unable to reproduce it reliably.
It's just a simple view with a label or two on it. We've tried setting a zIndex on the overlay too, but that didn't make a difference.
Any ideas?
I upgraded my iPad to iOS 8.3, and there is a bug - overlay does not respond to any clicks (nor the buttons or anything).
Any idea how to solve this?
iOS version only reads QR code, not 1D barcode.
Any help with that?
this module only works in landscape mode on android device ,nice working module though!

I have tested the module on a simple app witn an Android device
Image from phone camera
Image from app-module camera
The image is distorted vertically, and this obviously negatively affects the recognition of the qr-code.
Hi,
I just want to tell you something about the module, I´m working with an application in order to scan a QR code in 2 separated profiles, the second Barcode.addEventListener('success', call at the first option even when I tell to the application "I´m in window 1" so you need to fire this function and not of the Window #2.
On a device running Android 6, when the app tries to use the camera to scan the message "Sorry, the Android camera encountered a problem. You may need to restart the device." is shown and the camera cannot be used.
The status bar text of the Barcode.capture call is always black. I have UIStatusBarStyle in tiapp.xml set to UIStatusBarStyleLightContent but it's still black text when opening the Barcode.capture.
Is there something I can do to get LIGHT_CONTENT on the Barcode.capture window?
Hi guys,
i´ve an issue with the overlay(Imageview). When i add a cancel button on it, it doesn´t react. It´s only responding on the button, when i lay down the phone on the table.
Seems to be the overlay is under the camera view or something like that.
The Parameter "showCancel" doesn´t work at all with an overlay.
I use your latest version, 1.9.1, project build with Titanium SDK 3.5.1 on an IPhone 5 with IOS 8.3
Hope it can be fixed soon.
Thanks for your help :)
UISupportedInterfaceOrientations is set to only UIInterfaceOrientationPortrait, but ti.barcode's window ignores it.
Hy,
I'm using your module for my app, but at iOS it's not changing orientation correctly. See screenshots.
Using iPhone 6 iOS 8.2.
Ti 4.0.0.v20150323131014
Xcode 6.2
ti.barcode 1.9.1
I wanted to implement iOS version in my app and I tried the sample app it doesn't work at all. This has a issue when rotating the screen. The main issue what I find here is it doesn't scan at all. Could you please help me on this?
Please find the attached pics.
Hi good day I hope Someone can help please. In the Barcode.capture function there is a parameter: animated, but I don't know what it does.
I put it false, i put it true but I don't notice a difference.
In the documentation says: "animate[boolean]: Indicates if the device should animate between the current activity and the camera activity when the current activity is in a different orientation than the camera. Default is true". But I don't understand what it does. Can You help me please! I'm from Mexico and my native language is Español.
Thanks
Compiling the latest source and making an app with the example app.js, the camera view is rotated 90 degrees on iPad, when using landscape mode. Is this a case of the example being outdated, or something else?
Hello,
Used this module's android version and worked as per my requirement. Needed the attribute named as "format" in my app. But currently facing problem with IOS version as it doesn't include the "format" in its callback response while returning from scanning barcode.

If i am trying to scan a QR code on iOS it is very hard to find the correct distance with the camera. Also it takes quite long before the QR Code is detected. I have found out that you have to come very close before the code is detected - this on the other hand causes problems with the auto focus of the camera. If have tested this with an iphone 5c and an iphone 7.
Looking forward to your feedback!
I have developed android application in appcelerator studio which is based on android-5. Now i have to give support on android-7 for same app then how can i give support same app andoid-5 to android-7.
Thanks
