Phone state listener called multiple times

hi i want to log the incoming number to the database. i am using broadcast receiver to listen for phone calls and using phone state listener.
here is my code

ThePhoneStateListener.java

package com.example.netlogger.Receiver;
import android.content.Context;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;

public class ThePhoneStateListener extends PhoneStateListener {
Context context;
public ThePhoneStateListener(Context context) {
this.context = context;
}
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
if (state == TelephonyManager.CALL_STATE_OFFHOOK) {
Log.d("TAGG", "Insert: " + incomingNumber);
}

}
}


CallActionReceiver.java

package com.example.netlogger.Receiver;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.widget.Toast;

public class CallActionsReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context arg0, Intent arg1) {
TelephonyManager manager = (TelephonyManager) arg0
.getSystemService(arg0.TELEPHONY_SERVICE);
manager.listen(new ThePhoneStateListener(arg0),
android.telephony.PhoneStateListener.LISTEN_CALL_STATE);
}
}


Menifest.xml

<receiver android:name="com.example.netlogger.Receiver.CallActionsReceiver">
<intent-filter android:priority="2147483647">
<action android:name="android.intent.action.PHONE_STATE"/>
</intent-filter>
<intent-filter android:priority="2147483647">
<action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
</intent-filter>
</receiver>


in
ThePhoneStateListener
onCallStateChanged() why it is called multiple times. i want to insert incoming number to database just once.

Answer

Some how , i solved it. the problem is that when ever my broadcast receiver's onReceive() was invoked ,every time i was trying to listen a new PhoneStateListener.You just need to do it once. just like following

package com.example.netlogger.Receiver;

import java.util.Date;

import com.example.netlogger.util.LocalDatabase;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.widget.Toast;

public class CallActionsReceiver extends BroadcastReceiver {
    static ThePhoneStateListener phoneStateListener;



    @Override
    public void onReceive(Context arg0, Intent arg1) {
        TelephonyManager manager = (TelephonyManager) arg0
                .getSystemService(arg0.TELEPHONY_SERVICE);      
        if (phoneStateListener == null) {
            phoneStateListener = new ThePhoneStateListener(arg0);
            manager.listen(phoneStateListener,
                    android.telephony.PhoneStateListener.LISTEN_CALL_STATE);
        }


    }

}

Problem solved. Cheers
