Message handlers

I have a thread, initialthread that executes a task every n seconds. This is enclosed in activity A. i have a message handler on activity B.

mHandler = new Handler(){
public void handleMessage(Message msg)
  {
   //perform task
    executetask();
  }
};

Will this handler excutetask() whenever the initialthread finishes executing?? th开发者_开发技巧anks

It will execute whenever you pass the massage from the initial thread.

I mean whenever you call .sentMessage() from the initial thread.
