your force close is due to the fact that you haven't set the flags
necessary for calling an activity from a receiver..
here is how you should call a
public void onReceive(Context context, Intent intent)
{
Intent startalarm=new Intent(context,YOUR_CLASS_TO_CALL);
startalarm.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP|
Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(startalarm);
}
Setting these flags will solve your problem
