Here def no getting message as Couldn't load data
please help me

Replace with this:
DefaultData = getSharedPreferences("defMobileNo",0);
final String defNo = DefaultData.getString("defMobileNo","Couldn't load data");
final String defMsg = DefaultData.getString("defMessgae","Couldn't load data");

This is how basically sharedpreference work
To Store the values
SharedPreferences preferences = getSharedPreferences("AUTHENTICATION_FILE_NAME", Context.MODE_WORLD_WRITEABLE);
SharedPreferences.Editor editor = preferences.edit();
editor.putString("Name","myNameisnothing");
editor.commit();
To get the values
SharedPreferences prfs = getSharedPreferences("AUTHENTICATION_FILE_NAME", Context.MODE_PRIVATE);
String name = prfs.getString("Name", "");
This way it'd return the value of the name as myNameisnothing.
PS.Correct me if im wrong.

You are wrongly using
DefaultData = getSharedPreferences("defMessgae",0); in DefSMS.java
Please remove this and it will work fine.
You were trying to get shared preference named defMessgae which doesnot even exist. So when you try to access it, android will create a new preference with default value. That is why you were getting "Couldn't load data"

How to get data from activity class to the PhoneStateListener class?

I have a problem in which I can't get data from activity class to the PhoneStateListener class.
for better understanding the code is as below:
This is the class from where I want to send the data or string
package net.cellobject.blockingincomingcall;
import android.app.Activity;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class SecondTab extends Activity
{
EditText e1;
Button b1;
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.setting);
e1=(EditText)findViewById(R.id.edt1);
b1=(Button)findViewById(R.id.b1);
LoadPreferences();
b1.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
String msg=e1.getText().toString();
SavePreferences("msg1",msg);
LoadPreferences();
if(msg=="")
{
Toast.makeText(getApplicationContext(), "First
Enter the message then save it"
,Toast.LENGTH_LONG).show();
e1.requestFocus();
}
}
});
}
private void LoadPreferences()
{
SharedPreferences shp= getPreferences(MODE_PRIVATE);
String s1=shp.getString("msg1","");
e1.setText(s1);
}
private void SavePreferences(String key, String msg)
{
SharedPreferences shp= getPreferences(MODE_PRIVATE);
SharedPreferences.Editor editor=shp.edit();
editor.putString(key, msg);
editor.commit();
}
}
This is the class where I want to get the data or string which is extends with PhoneStateListener?
package net.cellobject.blockingincomingcall;
import java.lang.reflect.Method;
import android.content.Context;
import android.media.AudioManager;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
import com.android.internal.telephony.ITelephony;
public class PhoneCallStateListener extends PhoneStateListener
{
private Context context;
public PhoneCallStateListener(Context context)
{
this.context = context;
}
public void onCallStateChanged(int state, String incomingNumber)
{
switch (state)
{
case TelephonyManager.CALL_STATE_RINGING:
AudioManager audioManager = (AudioManager) context.
getSystemService(Context.AUDIO_SERVICE);
//Turn ON the mute
audioManager.setStreamMute(AudioManager.STREAM_RING, true);
TelephonyManager telephonyManager = (TelephonyManager) context.
getSystemService(Context.TELEPHONY_SERVICE);
try {
#SuppressWarnings("rawtypes")
Class clazz = Class.forName(telephonyManager.getClass().getName());
Method method = clazz.getDeclaredMethod("getITelephony");
method.setAccessible(true);
ITelephony telephonyService = (ITelephony) method.invoke(telephonyManager);
//Checking incoming call number
String incoming=incomingNumber.toString();
if (incomingNumber.equalsIgnoreCase(incoming))
{
Log.v("incoming_call",incoming);
telephonyService.endCall();
sendSMS(incoming, "I am Busy!!call me later");
}
} catch (Exception e) {
e.printStackTrace();
}
audioManager.setStreamMute(AudioManager.STREAM_RING, false);
break;
}
super.onCallStateChanged(state, incomingNumber);
}
private void sendSMS(String incoming, String string)
{
android.telephony.SmsManager sms=android.telephony.SmsManager.getDefault();
sms.sendTextMessage(incoming, null, string, null, null);
}
}

Since you have Context in both Activity and Receiver you may use SharedPreference to set and get data on both places.. WHats the problem..
context.getSharedPreference("name" , MODE_PRIVATE);

im posting a very simple method to store and get preferences, use this i will solve your problem related to store and retrieve preferences.
public class Preferences {
public static void record(String key,Context context,String value)
{
SharedPreferences pref=PreferenceManager.getDefaultSharedPreferences(context);
SharedPreferences .Editor editor=pref.edit();
editor.putString(key,value );
editor.commit();
}
public static String getRecord(String key,Context context)
{
return PreferenceManager.getDefaultSharedPreferences(context).getString(key,PREF_DEFAULT_VALUE);
}
}

Not able to stop the service.?

}
}
I want to stop the service when call idle.

hi in actionStop method instead of stopService method call you have called startService method again.
ctx.stopService(i);
Use the above line instead of that and tel the response
