Web service platform for communicating with android app

fixed the issue. Will look into that further I know this isn't a direct answer but I would shy away from any sort of offical XML-based web services. I've found that JSON is far less verbose and generally leads to faster response times as opposed to full blown SOAP messages. I would urge you to evaluate JSON as your "transport" mechanism.

Mobile platform communicating directly to database or via web service?

Mobile platform communicating directly to database or via web service?

seems to work fine The usual way would be through a REST API (or some other kind of web service / service layer).
Putting the database open in the wild, directly accessible from any outside device, is certainly a bigger security hole than using a service layer.

I hope this helps you . I assume you are using a started service as opposed to a bound service. When you call startService() the first time, the service is "created" (i.e., onCreate()) is called. After that, any time you call startService(), the onStartCommand() is called.
So yes - a single instance of the service is running at any time. You can just call startService() from both the Activity and the AlarmReceiver and the Intent will be delivered to the Service if it has already been created; else the Service is created and then the Intent is delivered to it.

will be helpful for those in need As long as you only need to communicate within your own application, there's nothing wrong with using a message bus.
I do this quite a bit, and it works well, and is much less complicated than other methods.

Hope this helps You need to use bindService() to bind with running service and communicate with it.
Reference : http://developer.android.com/guide/components/bound-services.html
code :
public class BindingActivity extends Activity {
YourService mService;
boolean mBound = false;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}

@Override
protected void onStart() {
    super.onStart();
    // Bind to Your Service
    Intent intent = new Intent(this, YourService.class);
    bindService(intent, mConnection, Context.BIND_AUTO_CREATE);
}

@Override
protected void onStop() {
    super.onStop();
    // Unbind from the service
    if (mBound) {
        unbindService(mConnection);
        mBound = false;
    }
}

/** Called when a button is clicked (the button in the layout file attaches to
  * this method with the android:onClick attribute) */
public void onButtonClick(View v) {
    if (mBound) {
        // Call a method from your Service.
        // However, if this call were something that might hang, then this request should
        // occur in a separate thread to avoid slowing down the activity performance.
        int num = mService.getRandomNumber();
        Toast.makeText(this, "number: " + num, Toast.LENGTH_SHORT).show();
    }
}

/** Defines callbacks for service binding, passed to bindService() */
private ServiceConnection mConnection = new ServiceConnection() {

    @Override
    public void onServiceConnected(ComponentName className,
            IBinder service) {
        // We've bound to the running Service, cast the IBinder and get instance
        LocalBinder binder = (LocalBinder) service;
        mService = binder.getService();
        mBound = true;
    }

    @Override
    public void onServiceDisconnected(ComponentName arg0) {
        mBound = false;
    }
 };
}
 public class LocalService extends Service {
    // Binder given to clients
   private final IBinder mBinder = new LocalBinder();
   // Random number generator
   private final Random mGenerator = new Random();

/**
 * Class used for the client Binder.  Because we know this service always
 * runs in the same process as its clients, we don't need to deal with IPC.
 */
public class LocalBinder extends Binder {
    LocalService getService() {
        // Return this instance of LocalService so clients can call public methods
        return LocalService.this;
    }
}

@Override
public IBinder onBind(Intent intent) {
    return mBinder;
}

/** method for clients */
public int getRandomNumber() {
  return mGenerator.nextInt(100);
  }
}

around this issue The Bound Service approach detailed here is appropriate. You don't have to worry about Handlers, or even Intents (once the client is bound).
Referring to the example at the given link: You can simply add functionality on to the LocalService object, e.g.,
code :
/** method for clients */
public int getRandomNumber() {
  return mGenerator.nextInt(100);
}

private Set<MyEventListener> mListeners = new HashSet<>();

/** A MyEventListener (your Activity, Fragment, etc.) calls this in its
 * onServiceConnected() method, on the reference it gets from getService(). */
public void registerListener(MyEventListener listener)
{
    mListeners.add(listener);
}

public void sendEvent()
{
    for(MyEventListener listener : mListeners)
    {
         listener.onEvent();
    }
}
