[TIMOB-15439] Android: App crashes with just a few ImageViews

Description of the problem

When there are few ImageViews in the app, if the image is big, the Emulator crashes with an 'out-of-memory' error. Images in the test is 280KB and is added 5 times to the app.

Steps to reproduce

Use the attached image, and the following code:

var win = Ti.UI.createWindow({
	backgroundColor: 'black'
});

function createImageView() {
	var iv = Ti.UI.createImageView({
		backgroundImage: '/background_main.png'
	});
	
	return iv;
}

for (var i=0; i<5; i++) {
	win.add(createImageView());
}

win.open();

Note

Running this on Nexus 4 with Android 4.3.3 works fine; same using SDK 3.1.2. Before the crash, the heap size increases up to ~48MB and then the app exits.
