android - Strange function in ActivityManager: isUserAMonkey. What does this mean, what is its use?

itemprop="text">

I found the following function in
package
android.app.ActivityManager.

public
            static boolean isUserAMonkey
            ()

The href="http://developer.android.com/reference/android/app/ActivityManager.html#isUserAMonkey()">reference
describes:

public static boolean isUserAMonkey () Since: API
Level 8

Returns "true" if the user interface
is currently being messed with by a
monkey.

I
was shocked by this strange function. And have a few
questions.

• What
  does this (user interface is currently being messed with by a
  monkey)
  mean?




• What is the practical use of
  this function?




• Why do they use
  isUserAMonkey for the function
  name?

Answer

This method is for checking whether the
current user is a rel="nofollow noreferrer">test user by some automatic testing, called 'monkey' by
Android devs.
