Question

I have a question about threading in android

If call a method which is in my activity from a run() method of a new thread is that method executed in that new thread or in main thread. for example.

  ...
  public void run()
   {
    someMethod(); //some method declared in activity  
    }
  ...

Answer 1

Since each Thread has its own stack, and given that Threads don’t share stack. So, once a thread is started, then any method invoked from it will be executed in that Thread only.
