IBM Worklight 6.0 - Dojo application doesn't work on Samsung Galaxy S3

问题

I haven't been able to get any worklight/dojo apps to work on the Samsung Galaxy S3. I have put together a trivial Worklight application in Worklight Studio v6. It has 2 views. The first view has a text box and a button, the second view has a text box.

<div data-dojo-type="dojox.mobile.ScrollableView" id="view0"
    data-dojo-props="selected:true">
    <div data-dojo-type="dojox.mobile.Heading"
        data-dojo-props="label:'Page 0'"></div>
    <input data-dojo-type="dojox.mobile.TextBox">
    <button data-dojo-type="dojox.mobile.Button" id="theButton">Page
        1</button>
</div>
<div data-dojo-type="dojox.mobile.View" id="view1">
    <div data-dojo-type="dojox.mobile.Heading"
        data-dojo-props="label:'Page 1',back:'back',moveTo:'view0'"></div>
    <input data-dojo-type="dojox.mobile.TextBox">
</div>

The button on view0 is connected to a handler that transition to view1, and the header on view1 has a back button.

        dijit.registry.byId("theButton").on("click", function() {
            dijit.registry.byId("view0").performTransition("view1", 1, "slide");
        });

That's all there is to the app. It works everywhere I've tried it (emulators and Motorola Droid 4) except on the Galaxy S3. On the Galaxy, it looks like the dojo parser is failing. The page is white, the text boxes and button from both views are shown on the initial page, but there are no headers and nothing happens when you click on the button. Both the Motorola (where it works), and the Samsung (where it doesn't) are running Android 4.1.2.

Looking in LogCat for the Samsung, I see a few errors that I don't see on other platforms:

08-01 16:51:42.752: D/SimpleTest(26821): before: app init onSuccess

Googling around, I find references to the SPAN_EXCLUSIVE_EXCLUSIVE error. It seems to be associated with the Swype, or SwiftKey keyboards, or to Samsung TouchWiz. Most references to this problem are from folks doing Android native development, not hybrid app development, and other than disabling keyboards, I'm not finding many answers. I tried disabling the Swype keyboard, but that didn't change anything. Has anyone else seen this problem? Has anyone gotten a Worklight 6 dojo app to run on a Galaxy S3?

Try to use this 'mobile-ui-layer.js' in your www/layers folder. Just copy the file and recompile the application.

The fix is based on the following problem:

回答2:

This will be fixed in a near future release for Worklight 6.0.
