AsyncTask not called in service

Am presently trying to call an AsyncTask from my service, but every time the service is called the AsyncTask that it is meant to perform is not called or not working. i have tried using this same service to call a text message method and it works but it is not working for the AsyncTask. My service class is below.

Connection Loss Handling in AsyncTask in Android

In My application i have read all the record from the DataBase SqlServer by using REST API.But there is some problem when connection loss at intermediate execution of protected DetailsTimeTable doInBackground(String... params). Then my app closed with error Unfortunately app has stopped
Here is my Code:
public class Monday_Time extends ListActivity {

private ProgressDialog progressDialog;

new AsyncDetailsTimeTable().execute(MainActivity.branch_static.trim(), MainActivity.sem_static.trim(), MainActivity.sec_static.trim(), "Monday");
}

if (SSTCTimeTableTabActivity.ram == 1) {

alert.show();
} else {

setListAdapter(new ArrayAdapter<String>(getApplicationContext(), R.layout.rowlayout, R.id.label, itemsList));
}
super.onPostExecute(result);
}
#Override
protected DetailsTimeTable doInBackground(String... params) {
DetailsTimeTable userDetail = null;
RestAPI api = new RestAPI();
try {
JSONObject jsonObj = api.GetTimeTableDetails(params[0], params[1], params[2], params[3]);
JSONParser parser = new JSONParser();
userDetail = parser.parseUserDetails(jsonObj);
} catch (Exception e) {
// TODO Auto-generated catch block
Log.d("AsyncUserDetails", e.getMessage());
}
return userDetail;
}
}
}

catch (Exception e) {
// TODO Auto-generated catch block
// Log.d("AsyncUserDetails", e.getMessage());
}
Try to comment Log print. I think e.getmessage() throwing NullPointerException.

And permission in Menifest file are
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

You have to save all proximity region IDs(request code) and when u want to remove these region just call to remove from locationmanager . For e.g.
Intent intent = new Intent();
intent.setAction(AppConstants.BROAD_ACTION);
for(int i=0;i<countRegionIDArr.size();i++){
PendingIntent pendingIntent = PendingIntent.getBroadcast(AlertService.this, countRegionIDArr.get(i), intent, 0);
mlocManager.removeProximityAlert(pendingIntent);
}

onStartCommand Call after Destroying an Activity

i'm observing a weird scenario here. I have a background android service which is running perfectly. but when I kill the process or application from my RecentApps my Application calls the onStartCommand method again. I don't know where I went wrong. I have searched alot but didn't find any appropriate solution. Could someone please mention what I did wrong? Thanks in Advance

06-03 12:25:48.221: E/Attendence(30447): Service Created
here in the logcat the last line shows that its call the onstartcommand method again. Why is it so? Even my Activity is not running I meant to say (the service starts in oncreate method on on acticity, but here in the logcat the control goes directly to the onStartCommand when i destroy my App ).

Your service will be START_STICKY so the android framework is restarting it -> This will give you call to onStartCommand()
I changed my service to START_NOT_STICKY so the android framework will not restart my service on its own without any explicit request from out application
To make your service of START_NOT_STICKY, just return value Service.START_NOT_STICKY from onStartCommand()
This worked and solved my issue

hii i want to open alert if internet is not available and also check if response getting time out..how is it posible??? help me..here is my code of asynctask which is new GetVideoUrlAsyn().execute(); method..

Check network connectivity before executing AsyncTask,
if(isNetworkAvailable(this))
{
new GetVideoUrlAsyn().execute();
}
and this is the method definition,
public boolean isNetworkAvailable(Context ctx)
{
ConnectivityManager cm = (ConnectivityManager)ctx.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
if (netInfo != null && netInfo.isConnectedOrConnecting()&& cm.getActiveNetworkInfo().isAvailable()&& cm.getActiveNetworkInfo().isConnected())
{
return true;
}
else
{
return false;
}
}
do something like this inside your method callhttppost_numvaluepair(URL, nameValuePairs) of WebServiceCall class,
HttpParams basicparams = new BasicHttpParams();
URI uri = new URI(url);
HttpPost method = new HttpPost(uri);
int timeoutConnection = 60000;//set your timeout period
HttpConnectionParams.setConnectionTimeout(basicparams,
timeoutConnection);
DefaultHttpClient client = new DefaultHttpClient(basicparams);
//and then rest of your code
Note:
Don't forget to put the permission in manifest file,
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

You should use a broadcast receiver as mentioned in other SO answers, but since you have asked how to do this otherwise, here you go:
* Checks for an existing network connectivity
*
* #param context
* The {#link Context} which is needed to tap
* {#link Context#CONNECTIVITY_SERVICE}
* #return True if network connection is available
*/
public static boolean isNetworkAvailable(Context context) {
ConnectivityManager connectivity = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity == null) {
return false;
} else {
NetworkInfo[] info = connectivity.getAllNetworkInfo();
if (info != null) {
for (int i = 0; i < info.length; i++) {
if (info[i].getState() == NetworkInfo.State.CONNECTED) {
return true;
}
}
}
}
return false;
}
Will need additional permission to be specified in the manifest file

check internet before execute asyncTask
if(checkNetwork)
{
new GetVideoUrlAsyn().execute();
}
else
{
// do stuff
}

if(CheckNetwork){
new GetVideoUrlAsyn().execute();
}else{
// Check internet connection
}
and
private boolean CheckNetwork() {
ConnectivityManager conMgr = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
if (conMgr.getActiveNetworkInfo() != null
&& conMgr.getActiveNetworkInfo().isAvailable()
&& conMgr.getActiveNetworkInfo().isConnected()) {
return true;
} else {
return false;
}
}
