[TIMOB-14078] Android: Remote images not loaded at second load attempt when no internet connection on first load attempt

Problem

If a ImageView with a remote image is displayed to the user for the first time when no internet connectivity is available, the remote image will also not show if it is displayed later on when internet connectivity is available. Only after a restart of the application the remote image will show. Titanium SDK 3.2.0 (HEAD) Android 4.2.1 Nexus S

Test case

1. Run the app from the code below with the device in "flight mode" (no internet connectivity) 2. Press the button "Open". The remote image will not show as expected. 3. Go back with the back button. 4. Put the app into background (do not close the app completely) 5. Disable flight mode and wait for the internet connectivity to restore 6. Open the app. 7. Press the button "Open". I would now expect the remote image to appear. But it won't appear. It will only appear, if the app is fully closed and opened again.

var win = Ti.UI.createWindow({});

var b = Ti.UI.createButton({
	title: 'Open'
});
win.add(b);

b.addEventListener('click', function(evt) {
	var win2 = Ti.UI.createWindow({ modal: false });
	
	var v1 = Ti.UI.createImageView({
		height: '64dp',
		width: '64dp',
		hires: true,
		backgroundColor: 'green',
		image: "https://raw.github.com/appcelerator/titanium_mobile/master/android/templates/app/default/Resources/android/appicon.png",
	});

	win2.add(v1);
	win2.open();
});

win.open();
