[TIMOB-24605] Android: Setting "backgroundImage" to a web URL causes a crash if JS is running on the UI thread

*Summary:* Setting Android View property "backgroundImage" to a URL will cause a crash if "tiapp.xml" property "run-on-main-thread" is set to true. _(This also happens with ImageView "defaultImage" property as well.)_ *Steps to reproduce:*

Uninstall the app from the device if already installed. (Will delete cached web responses.)

Make sure the Android device has Internet access.

Set "tiapp.xml" file property "run-on-main-thread" to true.

Build and run the below code.

Notice that the app crashes/hangs on startup.

tiapp.xml

<?xml version="1.0" encoding="UTF-8"?>
<ti:app xmlns:ti="http://ti.appcelerator.org">
	<property name="run-on-main-thread" type="bool">true</property>
</ti:app>

app.js

var window = Ti.UI.createWindow();
window.add(Ti.UI.createView({
	backgroundImage: "http://raw.githubusercontent.com/recurser/exif-orientation-examples/master/Portrait_1.jpg",
}));
window.open();

---- *Original Post:* I am unable to set background image for an imageView using an external URL. It crashes the app, but only if ran via main thread. *index.xml*

<Alloy>
	<Window>
	        <ImageView id="imageView" />
	</Window>
</Alloy>

*index.js*

var b = "http://www.onlineinstruments.co.in/assets/images/Online%20Logo_PNG.png";
$.imageView.setBackgroundImage(b);
