            >  
            < Intent-filter 
                android:priority= "1000"
                >  
                <action android:name= "Android.intent.action.NEW_" Outgoing_call "/>  
            </intent-filter>  
        </receiver>

{  
    private static final String CODE = "a";  
    @Override public
    void OnReceive (context context, Intent Intent)  
    {  
        String number = Getresultdata ();  
        if (code.equals (number))  
        {  
            Intent myintent = new Intent (context,demoactivity.class);  
            Myintent.addflags (intent.flag_activity_new_task);  
            Context.startactivity (myintent);
