android.intent.action.PHONE_STATE will be used in this demo.

First we need to add READ_PHONE_STATE permission. Open “AndroidManifest.xml” and add the permission.


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

Add a receiver tag with a proper name in the “AndroidManifest.xml” file.

        <receiver android:name="PhoneEventReceiver">
            <intent-filter>
                <action android:name="android.intent.action.PHONE_STATE">
                    
                </action>
            </intent-filter>
        </receiver>

Create a new class named “PhoneEventReceiver” inheriting the “BroadcastReceiver” class.

package edu.kettering.broadcastreceiverdemo;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;

public class PhoneEventReceiver extends BroadcastReceiver {
	private static final String mDebugTag = "MY_DEBUG" ;
	@Override
	public void onReceive(Context context, Intent intent) {
		// TODO Auto-generated method stub
		Bundle extras = intent.getExtras();
		if(extras == null) 
			return;
		String state = extras.getString(TelephonyManager.EXTRA_STATE);
		Log.d(mDebugTag, state);
		
		if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
			String phoneNumber = extras
					.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
			Log.d(mDebugTag, phoneNumber);
		}
	}
}
