acktie-mobile-android-barcode's Issues

DataMatrix?

No issue ... but it would be great if the scanner can also recognize DataMatrix code!

UPC alone not working.

When the UPC array is used (per the example), Android devices fail to recognize any barcodes. Only when UPC includes EAN are you able to scan UPC barcodes.

Ti SDK 5.1.2.GA and Android API 23 exception

It worked fine on Ti SDK 5.0.2.GA and Android API 21, now it is not working anymore.

Please, it is by far the best barcode scanner module out there!

Question About App Backgrounding Crash

I know you guys are probably not doing much more work on this having moved off of titanium (from what I remember), so this is more just a question incase you have any thoughts (as it's causing a much larger issue than I assumed it would :) ).

I'm seeing a crash happen a lot any time I'm on a page with a BarcodeView on it and I background the app. The crash seems to happen as soon as I open the app back up (or possibly after backgrounding, I'm not quite sure yet as I don't notice it until I open it again).

The log coming from the crash is:

0   
java.lang.NullPointerException

I'm going to keep looking around, it looks somewhat related to this (http://stackoverflow.com/questions/7850419/android-surfaceview-crashes-when-go-to-background) but if anything comes to mind that mind help I'd be extremely grateful!

Thanks!

Android Scan Crop

Currently the Android version lacks real-world applicability due to the inability to determine what is being scanned when codes are close together. Store shelves, warehouses, and other places where products are grouped together will not work in this instance. zBar has a scan crop method but I am not sure zBar is being utilized in this way, so I am unable to correctly add to the module.

App force closes

Using essentially the code from your sample app the barcode scans, the barCodeWindow closes, and the module calls my success function (which opens a new window). Upon closing that window, I see the following in Monitor:

Further details:

  • I am using a custom build of your module because the GUID used on your GitHub repo has been reused or something. I get license verification errors if I use one of the dist versions.
  • I changed the paths to my SDK, NDK, etc. but did not change your actual module code in any way.
  • I have tried building with both the 3.5.1.GA and 5.0.0.GA Titanium SDKs and get the same result with both.
  • I am testing on a Galaxy Nexus running Android 4.2.2. I see the same error on a S5 running 5.0.0.
  • My test app is a tab-based app. A button on a tab launches the code I adapted from your sample app, specifically the scanBarcodeFromCamera() function. Thus, your code has me opening a non-modal window atop a tab group, which is generally not something Titanium likes you to do.
var barcodescanner;
function showScanner() {
    barcodescanner = require("com.acktie.mobile.android.barcode");
    var CODE = [
        "CODE39",
        "CODE93",
        "CODE128",
    ];
    var options = {
        backgroundColor: 'black',
        width: '100%',
        height: '90%',
        top: 0,
        left: 0,
        allowZoom: true,
        userControlLight: false,
        barcodes: CODE,
        success: success,
        cancel: cancel,
        error: error
    };

    scanBarcodeFromCamera(options);
}

function success(e) {
    // async func here to look up the barcode and open 
    // new window on success. this works, however, closing
    // that new window shows the crash
    lookupBarcode(e.data, onSuccess, onError);
}

function scanBarcodeFromCamera(options) {
    var barcodeCodeWindow = Titanium.UI.createWindow({
        backgroundColor: 'black',
        width: '100%',
        height: '100%',
        theme: "Theme.AppCompat.NoTitleBar.Fullscreen"
    });
    var barcodeCodeView = barcodescanner.createBarcodeView(options);

    var closeButton = Titanium.UI.createButton({
        title: "Cancel",
        bottom: 0,
        left: 0
    });
    var lightToggle = Ti.UI.createSwitch({
        value: false,
        bottom: 0,
        right: 0
    });

    closeButton.addEventListener('click', function () {
        barcodeCodeView.stop();
        barcodeCodeWindow.close();
    });

    lightToggle.addEventListener('change', function () {
        barcodeCodeView.toggleLight();
    });

    barcodeCodeWindow.add(barcodeCodeView);
    barcodeCodeWindow.add(closeButton);

    if (options.userControlLight !== undefined && options.userControlLight) {
        barcodeCodeWindow.add(lightToggle);
    }

    // NOTE: Do not make the window Modal.  It screws stuff up.  Not sure why
    barcodeCodeWindow.open();
}
