1. The thread where the Handler is located is new and the Runnable is executed.

 

2. There is a bug where the Activity is started multiple times. How can this problem be solved?

Method 1. Set the Activity to start to be a singleton only.
In the function list file android: launchMode = "singleTask"
Method 2. control from the source and execute the Code only once

Private boolean isStartMain = false;/*** jump to the homepage and close the current page */private void startMainActivity () {if (! IsStartMain) {isStartMain = true; Intent intent = new Intent (this, MainActivity. class); startActivity (intent); // close the current page finish ();}}
