reciever

    package com.me.phone;  import android.content.broadcastreceiver; import android.content.context; import android.content.intent;  public class recieve extends broadcastreceiver{      @override     public void onreceive(context context, intent intent)      {         intent activity = new intent(context, mainactivity.class);         activity.addflags(intent.flag_activity_new_task);         context.startactivity(activity);     }  } 

could "receive" spelled 2 different ways in example?

from exception:

...java.lang.classnotfoundexception: com.me.phone.receive 

from manifest:

<receiver android:name=".recieve" >
