Question

I wrote a script to simulate the user actions. The workflow is, for example, first tap an icon, launch an activity. Then do other actions.
The question is , I don’t know the exact time that the activity launched completely. At present, I use sleep to make my script wait.
Is there any way to know when an activity launched completely?

Answer 1

Is your final task is to run something after activity is launched… do this

First method called from activity is onCreate() , Hence we can say completing the onCreate() system calls onStart() which calls onResume() method… as onResume() completes you can say your activity is launched properly…

If you are not going to override onStart() or onResume() what I am going to describe can be written as last statements of onCreate(). That’s I usually do when I don’t need onStart() or onResume().

You can create an object of Handler. Like

Handler handler = new Handler();

Handler has a method postDelayed() that is called some times after the creating and launching is finished.

call it like

handler.postDelayed(runnable,timeInMilliSeconds);

after all the processes finish, application will wait for timeInMilliSecondsms to start the process defined in run method of runnable provided in postDelayed …..

Thus

If your task is to know when the launching is finished the answer is: at the end of onResume() called from your onStart() ….

If you want to perform some action use handler.PostDelayed() method and keep timeInMilliSeconds very low… [between 1 to 10].
