KitKat Connection from URL get NullPointerException in AsyncTask

i'm new in java and android programming but i accepted a challenge launched by a friend and now i have to work hard.
I finally managed to have this type of activity working with AsyncTask but it seems to work well on all android but not on 4.4.2 KitKat.
The problem seems to be on url.openConnection and i tried many times to change the way in wich i do it but i haven't had positive results...
I have only to read file from an URL
This is my class code:
public class MenuActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu);
new HttpTask().execute();
}
public final class HttpTask
extends
AsyncTask<String/* Param */, Boolean /* Progress */, String /* Result */> {
private HttpClient mHc = new DefaultHttpClient();
#Override
protected String doInBackground(String... params) {
publishProgress(true);
InputStream inputstream = null;
URL url = null;
try {
url = new URL("http://somesite/prova.txt");
} catch (MalformedURLException e) {
e.printStackTrace();
}
assert url != null;
URLConnection connection = null;
try {
connection = url.openConnection();
} catch (IOException e) {
e.printStackTrace();
}
try {
HttpURLConnection httpConnection = (HttpURLConnection) connection;
httpConnection.setRequestMethod("GET");
httpConnection.connect();
if (httpConnection.getResponseCode() == HttpURLConnection.HTTP_OK) {
inputstream = httpConnection.getInputStream();
}
} catch (Exception ex) {
ex.printStackTrace();
}
ByteArrayOutputStream bytearryoutputstream = new ByteArrayOutputStream();
int i;
try {
i = inputstream.read();
while (i != -1) {
bytearryoutputstream.write(i);
i = inputstream.read();
}
inputstream.close();
} catch (IOException e) {
e.printStackTrace();
}
return bytearryoutputstream.toString();
}
#Override
protected void onProgressUpdate(Boolean... progress) {
}
#Override
protected void onPostExecute(String result) {
StringBuilder nuovafrase=new StringBuilder("");
String[] frasone=result.split("\n");
ListView listView = (ListView)findViewById(R.id.listViewDemo);
ArrayAdapter<String> arrayAdapter;
arrayAdapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.rowmenu, R.id.textViewList, frasone);
listView.setAdapter(arrayAdapter);
}
}
}
And this is the Logcat...

There is a Caused by: java.lang.NullPointerException but i cannot understand why...
Thanks

It could be caused by the inputstream being null. inputstream will only be initialized if the response code is OK. So you need to check what response code is being returned. If it is not causing the error, I'd still add some code for if the response code is not OK. You don't want your app to crash if it can't connect. You should at least display a helpful error message
Example:
else{
showErrorMsg();
return null;
}

Catch FileNotFoundException when trying inputstream.read();
try {
i = inputstream.read();
while (i != -1) {
bytearryoutputstream.write(i);
i = inputstream.read();
}
inputstream.close();
} catch (FileNotFoundException e) {
Log.e("MyTag","Handling empty page...");
} catch (IOException e) {
Log.e("MyTag",e.toString());
}

AsyncTask crashing Android Service

my AsyncCode and Service code is running fine, but when i merge them together it crashes my application's GUI, the code manages to write to the database.
I am new to android development so i do not quite know why it crashes.
This is my code for the method
#Override

There is a probleme with your SERVICE_URI variable. Maybe a misplaced space.
Or maybe you have forgotten the "http://" (or equivalent) at the beginning...

There seems to be a problem here:
Illegal character in scheme at index 0
which refers to this line here:
HttpPost request = new HttpPost(SERVICE_URI + "/StrongestWifi");
Most likely you have a space at the beginning of the SERVICE_URI?

I would bet that you have a space (' ') in front of the URL that you're passing:
192.168.1.64:4567/AllocationService.svc/StrongestWifi
Double-check that. You might just need to do a String#trim() on the URL.

In Your Async Task you should have Return type of doInBackground and postExecute must be same . And You are return null that why it give you error

According to the logcat, the code is crashing at line 43 with a Null Pointer Exception, and I can't tell which line 43 is. However:
Have you checked that Environment.getExternalStorageDirectory().getAbsolutePath() is returning non null? It maybe that there is no external storage directory, or you don't have permission to know about it.
It is also worth reading the developer pages, http://developer.android.com/reference/android/os/Environment.html#getExternalStorageDirectory(), which note that you shouldn't write to that directory, which you seem to be doing.

I solved this problem by myself. There was error in static variable who was changing his value due to logical error in code.

in 76th line..
use "URLEncoder.encode(args[0].toString()" instead of "URLEncoder.encode(arg0[0].toString()"

I cannot find why it crashes unexpectedly in doinbackground as I cannot see any error with my code I posted here.Any help is much appreciated.

what is LifeLogSecurityUtility?
It is possible this line:
[LifeLogSecurityUtility]lifelogdb permission error
is telling you that you are missing a permission tag in your manifest. Though I am not familiar with this LifeLogSecurityUtility so I wouldn't know which permission that thing is wanting you to have.

If you have not done so already add the WRITE_EXTERNAL_STORAGE permission to your AndroidManifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
