iOS/Android: read the bytes of a file

app.js

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

win.open();
var button = Ti.UI.createButton({
	title : "Click me!",
	height : 50,
	width : 200,
	top : 100
}); 
win.add(button);
button.addEventListener('click', function(e) {

	var resourceFileStream = Ti.Filesystem.openStream(Ti.Filesystem.MODE_READ, Ti.Filesystem.resourcesDirectory, 'KS_nav_ui.png');

	var buffer = Titanium.createBuffer({
		length : 32
	});
	
	// this will show the decimal representation of the first byte of the file
	// resourceFileStream.read(buffer);
	// Ti.API.info('buffer: ' + buffer[0]);

	// this will show the the bytes of the whole file in decimal and hex
	while(( size = resourceFileStream.read(buffer)) > -1) {
		Ti.API.info('===============================================');
		for (var i=0, j = buffer.length; i < j; i++) {
		  Ti.API.info("Decimal: "+buffer[i]);
		  Ti.API.info("Hex: "+buffer[i].toString(16));
		};
	}

});
