Answer 1

You need to register to_call_when_alarm_goes_off class in AndroidManifest.xml as receiver:

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

See details in API docs.

Answer 2

I assume you are missing registering your receiver in Manifest file, With appropriate action string. as given below.

         <receiver android:name=".to_call_when_alarm_goes_off" > 
               <intent-filter>
                  <action android:name="com.android.whatever.WHAT_EVER_NAM_YOU_WANNA_GIVE" />
                </intent-filter>// can change name/action string as par ur requirement.
        </receiver>

you need to set same action string in your intent, Remember Action string must be same in Manifest and here intent.setAction("com.android.whatever.WHAT_EVER_NAM_YOU_WANNA_GIVE"); in java also. then only it will tringger receiver.

Your code can be changed like given below.

Intent intent = new Intent(getApplicationContext(), to_call_when_alarm_goes_off.class);
intent.setAction("com.android.whatever.WHAT_EVER_NAM_YOU_WANNA_GIVE");// added line

PendingIntent pIntent = PendingIntent.getBroadcast(getApplicationContext(),0, intent, 0);

AlarmManager alarms = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

alarms.cancel(pIntent);


alarms.setRepeating(
        AlarmManager.RTC_WAKEUP,
        System.currentTimeMillis()+1000, 
        AlarmManager.INTERVAL_DAY, 
        pIntent);
