Question

I want to develope a receiver class which will listen Phone state. And I want to work on doSomething() using incoming phone number.

And my need is that my receiver should work between some time interval (like 12:30PM to 01:00PM), other than this time interval my receiver should not work.

What I did yet :

This is my BroadcastReceiver class :

public class MyTest extends BroadcastReceiver {
    protected AudioManager audioManager;// = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
    protected Context context;
    private ITelephony telephonyService;
    @Override
     public void onReceive(Context context, Intent intent) {
      audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
      this.context = context;
      String action = intent.getAction();
             if(action.equalsIgnoreCase("android.intent.action.PHONE_STATE")){
              if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
                                  TelephonyManager.EXTRA_STATE_RINGING)) {
                  //Incoming call 
               doSomething(intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER));
              }         
             }
             else {

             Bundle bundle = intent.getExtras();
             Object[] pdus = (Object[]) bundle.get("pdus");
             SmsMessage message = SmsMessage.createFromPdu((byte[])pdus[0]);
             if(!message.isEmail())
                 doSomething(message.getOriginatingAddress());

             }

     }
}

And I am using it as in my activity :

registerReceiver(new MyTest(), new IntentFilter("android.intent.action.PHONE_STATE"));

In manifest I declaired it as

<receiver android:name=".MyTest"></receiver>

Problem :

Its working if my application is running on foreground, but when I closes my application its not working.
I didn’t write any code on onPause() or other methods of Activity life cycle.

What am I doing wrong? Is there any other way to this?

Register your receiver in your manifest file like this:

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