is == null while getting xml file from internet

I have the following situation: I need to get xml file from the Internet and then get lyrics from this file. Here's the url of this xml. Here's the code, which I wrote and which should do it.
private static class NetworkLyricsDownload extends AsyncTask<Void, Void, Void> {
#Override
protected Void doInBackground(Void... voids) {
try {
URL url = new URL("http://api.chartlyrics.com/apiv1.asmx/SearchLyricDirect?artist=Eminem&song=Lose%20Yourself");
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(false);
XmlPullParser xmlPullParser = factory.newPullParser();
xmlPullParser.setInput(getInputStream(url), "UTF-8");
boolean insideItem = false;
int eventType = xmlPullParser.getEventType();
while (eventType!=XmlPullParser.END_DOCUMENT){
if (eventType == XmlPullParser.START_TAG){
if (xmlPullParser.getName().equalsIgnoreCase("lyric")){
insideItem = true;
Log.i(getClass().getName(), xmlPullParser.nextText());
}
}
eventType = xmlPullParser.next();
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
private InputStream getInputStream(URL url){
try {
return url.openConnection().getInputStream();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
But when I run the app, I have the following error:
E/AndroidRuntime: FATAL EXCEPTION: AsyncTask #2

I have permission in manifest file ( <uses-permission android:name="android.permission.INTERNET"/>
) but it still doesn't help. So, what's the matter and how can I solve it?
UPD
Here's my manifest file:

Android Development: “thread exiting with uncaught exception”

I'm trying to create my first Android App using php but I'm having some difficulties getting started.

It looks like you didn't initalize your 'identity' and 'password' ArrayLists. They are null when you compare it here:
if (String.valueOf(id.getText()) == String.valueOf(identity.get(0))
&& String.valueOf(pw.getText()) == String.valueOf(password.get(0))) {

Try to use
getSupportedActionBar() instead of getActionBar()

First of all, always do this to avoid this kind of error :
ActionBar ab = getSupportActionBar();
if (ab == null) {
Log.d("test", "ab null");
}
else {
Log.d("test", "ab not null");
ab.setDisplayHomeAsUpEnabled(true);
}
Then, what is in the logcat with the tag "test" ?

Make sure that you actually have an ActionBar, if for example, your theme is:
Theme.Light.NoActionBar, you won't have an action bar.
So, make sure your theme has and Actionbar
EDIT:
Try with the following theme:
<style name="AppTheme" parent="Theme.AppCompat">
If that doesn't work, You should consider changing to fragments, as suggested in this SO Answer

For both activities,
in your onCreate the next line after setContentView( ... )
add the following :
getActionBar().setDisplayHomeAsUpEnabled(true);
in the manifest for both activities add
android:theme="#android:style/Theme.Holo.Light"
in the tag directly after
android:screenOrientation="portrait"

Unable to start activity in inner class and activity class

I've got an android project from another developer. He can launch this project on his machine successfully, but when I try to launch it on my machine, I've got this exception when application trying load map in a fragment. The logcat with exception:

When I commented the code initializing the maps on these parts of application, it will start working normally.

Please verify that you have added the exceptions to your proguard configuration file. How and what to add is explained in Setting up Google Play Services

For the first, change your fragment from this:
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mapv2"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>
to this:
<fragment
android:name="com.google.android.gms.maps.SupportMapFragment"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
the main difference in this case is
class="com.google.android.gms.maps.SupportMapFragment"
to this:
android:name="com.google.android.gms.maps.SupportMapFragment"
For the second: add the following to the end of your manifest (but beforde the end-tag application!)
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
In your code you can ask for the service with the following:
// check status
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
try {
if (status != ConnectionResult.SUCCESS)
{
GooglePlayServicesUtil.getErrorDialog(status, this, RQS_GooglePlayServices).show();
}
} catch (Exception e) {
Log.e("Error: ", + e);
}

DataDevice class:
public class DataDevice extends Application
{
private Tag currentTag;
public void setCurrentTag(Tag currentTag) {
this.currentTag = currentTag;
}
public Tag getCurrentTag() {
return currentTag;
}
//(...)
}
I looked for answer on stackOverflow, nothing helped.
Anyone knows what's going on?
DataDevice and NFCUtilForeground works good (in other applications).

The android:name attribute in application tag in your manifest file should point to your DataDevice class. Like:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
android:name="your.package.DataDevice">
.........
..........
</application>
