Update your Manifest File.
Change tag android:name="Your.Pakage.Name.AppController"
"path.to.this.class.AppController"
<application

android:icon="#mipmap/ic_launcher"

Update:
Now you are setting actionbar properties and getting issue.
To fix change Activity to AppCompatActivity
ListViewActivity extend AppCompatActivity

Now you can get all the details in that spinner...

You can't Performing Network Operations ON GUI thread so you have to create a thread to fitch and parse data from URL.
public void onClick(View v) {
new Thread(new Runnable() {
#Override
public void run() {
item = SAXXMLParser.parse(URL);
spinhandler.sendEmptyMessage(0);
}
}).start();
}
Create Handler
private Handler spinhandler = new Handler() {
#Override
public void handleMessage(Message msg) {
if(msg.what == 0) {
ArrayAdapter<Item> adapter = new ArrayAdapter<Item>(MainActivity.this, R.layout.list_item, item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(MainActivity.this);
}
}
};
When try to put data in Item Object the Item object equal null so you have to intialize the object before start access it
if (qName.equalsIgnoreCase("id")) {
tempEmp = new Item();
tempEmp.setId(Integer.parseInt(tempVal));
}

Android RSS Reader (Ninja Error)

I followed a simple tutorial (http://www.cse.nd.edu/courses/cse40814/www/RSS_Android.pdf) to read RSS feed from a given URL into a listView. I have added the INTERNET permission and the code is error free in Eclipse but it will not show any RSS feed when launched on a device or emulator. I can't make the code anymore simpler, and the feed I am using is stable feed from www.nba.com : http://www.nba.com/rss/nba_rss.xml though i have tested it on several RSS feeds and with still no feed showing.
Any ideas guys?

replace

with

you lose the stack trace information.
