1. First create a new Android project

12. Create the following 2 Java class

MainActivity.java

package call.control;

import java.lang.reflect.InvocationTargetException;

import com.android.internal.telephony.ITelephony;

import java.lang.reflect.Method;

import android.app.Activity;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.content.IntentFilter;

import android.graphics.Color;

import android.os.Bundle;

import android.os.RemoteException;

import android.telephony.PhoneStateListener;

import android.telephony.TelephonyManager;

import android.telephony.gsm.~~SmsManager~~;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.CompoundButton;

import android.widget.EditText;

import android.widget.Toast;

import android.widget.ToggleButton;

import android.widget.CompoundButton.OnCheckedChangeListener;

public class MainActivity extends Activity{

ToggleButton blockAll_cb;

Button b1,b2;

BroadcastReceiver CallBlocker;

TelephonyManager telephonyManager;

ITelephony telephonyService;

EditText t1;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

t1=(EditText)findViewById(R.id.T1);

b1=(Button)findViewById(R.id.b1);

b2=(Button)findViewById(R.id.b2);

b1.setOnClickListener(new OnClickListener(){

@Override

public void onClick(View arg0) {

t1.setText("");

}});

b2.setOnClickListener(new OnClickListener(){

@Override

public void onClick(View arg0) {

finish();

}});

initviews();

blockAll_cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {

@Override

public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

blockAll_cb.setTextColor(Color.RED);

CallBlocker =new BroadcastReceiver(){

@Override

public void onReceive(Context context, Intent intent) {

telephonyManager = TelephonyManager)context.getSystemService

(Context.TELEPHONY_SERVICE);

Class c = null;

try{

c = Class.forName(telephonyManager.getClass().getName());

}

catch (ClassNotFoundException e) {

e.printStackTrace();

}

Method m = null;

try{

m = c.getDeclaredMethod("getITelephony");

}

catch (SecurityException e) {

e.printStackTrace();

}

catch (NoSuchMethodException e) {

e.printStackTrace();

}

m.setAccessible(true);

try {

telephonyService = (ITelephony)m.invoke(telephonyManager);

}

catch (IllegalArgumentException e) {

e.printStackTrace();

}

catch (IllegalAccessException e) {

e.printStackTrace();

}

catch (InvocationTargetException e) {

e.printStackTrace();

}

telephonyManager.listen(callBlockListener, PhoneStateListener.LISTEN_CALL_STATE);

}

PhoneStateListener callBlockListener = new PhoneStateListener(){

public void onCallStateChanged(int state, String incomingNumber){

if(state==TelephonyManager.CALL_STATE_RINGING){

if(blockAll_cb.isChecked()){

try{

String s=t1.getEditableText().toString();

telephonyService.endCall(); Toast.makeText(getBaseContext(), "Incoming Call No : "+incomingNumber,Toast.LENGTH_LONG).show();

String s1="Busy Now Call You Later";

if(s.length()>0){

~~SmsManager~~ sms=~~SmsManager~~.getDefault();

sms.sendTextMessage(incomingNumber, null, s, null, null);

}

else{

~~SmsManager~~ sms=~~SmsManager~~.getDefault();

sms.sendTextMessage(incomingNumber, null, s1, null, null);

}}

catch (RemoteException e) {

e.printStackTrace();

}}}}};};

IntentFilter filter= new IntentFilter("android.intent.action.PHONE_STATE");

registerReceiver(CallBlocker, filter);

}});}

public void initviews(){

blockAll_cb=(ToggleButton)findViewById(R.id.cbBlockAll);

blockAll_cb.setTextColor(Color.RED);

}

@Override

protected void onDestroy() {

super.onDestroy();

if (CallBlocker != null){

unregisterReceiver(CallBlocker);

CallBlocker = null;

}}}

MyStartupIntentReceiver.java

package call.control;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

public class MyStartupIntentReceiver extends BroadcastReceiver

{

@Override

public void onReceive(Context context, Intent intent)

{

Intent i = new Intent(context, MainActivity.class);

i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

context.startActivity(i);

}

3. Create the 2 layouts

Main.xml

________________________________________________________________________________

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical"

android:padding="20px" >

<TextView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text=""

android:textAppearance="?android:attr/textAppearanceMedium" />

<LinearLayout

android:id="@+id/linearLayout1"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:background="@drawable/frame"

android:padding="20px" >

<ToggleButton

android:id="@+id/cbBlockAll"

android:layout_width="wrap_content"

android:layout_height="66dp"

android:layout_weight="0.01"

android:background="@drawable/frame"

android:padding="16px"

<EditText

android:id="@+id/T1"

android:padding="16px" android:background="@drawable/frame"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="20dip"

android:layout_marginTop="5dip"

android:textColor="#ff0000"

android:singleLine="true" >

</EditText>

<LinearLayout

android:id="@+id/linearLayout2"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_weight="0.06"

android:gravity="center"

android:padding="20px" android:background="@drawable/frame" >

<Button

android:id="@+id/b1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginTop="10dip"

android:background="@drawable/frame"

android:padding="16px"

<Button

android:id="@+id/b2"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginTop="10dip"

android:background="@drawable/frame"

android:padding="16px"

android:text="Exit"

android:textColor="#FF0000" >

</Button>

</LinearLayout>

_______________________________________________________________________

Frame.xml

<?xml version="1.0" encoding="utf-8"?>

</shape>

4. Edit the android manifest file

Androidmanifest.xml

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

android:versionCode="1"

android:versionName="1.0" package="call.control">

<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

<activity android:name=".MainActivity"

android:label="@string/app_name">

<intent-filter>

</intent-filter>

</activity>

<receiver android:enabled="true" android:name=".MyStartupIntentReceiver"

android:permission="android.permission.RECEIVE_BOOT_COMPLETED">

<intent-filter>

</intent-filter>

</receiver>

</application>

<uses-sdk android:minSdkVersion="3" />

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

<uses-permission android:name="android.permission.MODIFY_PHONE_STATE"/>

<uses-permission android:name="android.permission.CALL_PHONE"/>
