java - Start service on boot: why it doens't work? -

i start service when phone boot not work , not understand why. in package created class

import android.content.broadcastreceiver; import android.content.context; import android.content.intent;      public class bootphone extends broadcastreceiver{          intent intent;          @override         public void onreceive(context context, intent intent) {             // todo auto-generated method stub             intent = new intent(context, service.class);             context.startservice(intent);         }      } 

my service.class is

public class service extends service{      notify notify;       @override     public ibinder onbind(intent arg0) {         // todo auto-generated method stub         return null;     }       @override     public void oncreate() {         // todo auto-generated method stub         super.oncreate();         notify = new notify(this);     }  } 

in manifest put

<service android:name="servicer"></service>     <receiver android:name="bootphone"                 android:enabled="true"                         android:exported="false" >         <intent-filter>             <action android:name="android.intent.action.boot_completed"/>                     </intent-filter>     </receiver> 

but, why does'n work? problem/error?

you have declare user permission in manifest

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