1.Handler on which thread new,runnable is executing on which thread

2. There is a bug that started multiple activity, how to solve?

Method ①. The activity set to start can only be a singleton.
In the feature manifest file android:launchmode= "Singletask"
Method ②. Control from the source, execute code only once

Private Boolean Isstartmain = false;/** * Jumps to the main page and closes the current page off */private void startmainactivity () {if (!isstartmain) { Isstartmain = true;intent Intent = new Intent (this,mainactivity.class); startactivity (Intent);//close current page finish ();}}
