This code var barcode =Ti.UI.createWebView({ top:"30%", left:"33%", height:"25%", width:"37%", url: "/local/jscode39.html" }) barcode.addEventListener('beforeload', function(e) { barcode.evalJS("var sku='"+barcodesku+"';"); }); Presents the barcode in IOS just like it should but just produces a blank white slate on Android 4.0. In the console it produces the following warnings and errors [WARN][webview ( 1051)] java.lang.Throwable: Warning: A WebView method was called on thread 'WebViewCoreThread'.

The file structure is APP Resources local then the HTML / JS and the gif images to load the barcode white and black bars on IOS it works like a champ (both in the simulator and a device) but not android either in the emulator or on a device Thanks John

    here is the JS code from titanium var barcodesku = "1234567890"; var barcode =Ti.UI.createWebView({ top:"30%", left:"33%", height:"25%", width:"100%", backgroundColor: "red", url: "/local/jscode39.html" }) barcode.addEventListener('beforeload', function(e) { barcode.evalJS("var sku='"+barcodesku+"';"); }); $.index.add(barcode); $.index.open(); here is the file that it is calling from the url line. named jscode39.html and this is the actual JS file that the html file calls . it is names code39.jslocal // JavaScript BarCode39 v. 1.0 (c) Lutz Tautenhahn, 2005 // The author grants you a non-exclusive, royalty free, license to use, // modify and redistribute this software. // This software is provided "as is", without a warranty of any kind.

When I run it in IOS it runs just fine and I can see the barcode. When I run it on Android 4.0.2 i get the webview core error messages and all I see i the background color (red). I got the barcode images from http://barcode-coder.com/en/barcode-jquery-plugin-201.html any idea what i am doing wrong? John
