installEventHandler()

installEventHandler(eventName, handlerFunctionNameOrReference)

This function installs a global event handler. The script function named or referenced in handlerFunctionNameOrReference, will be called when an event of the eventName type occurs.

The eventName can be the name of any of the following event types:

BannerShowed occurs when an android.widget.Toast is shown (deprecated, please use BannerShown instead; to be removed in the next feature release)
BannerShown occurs when an android.widget.Toast is shown
DialogOpened occurs when an android.app.AlertDialog is shown
Vibrate occurs when the app calls the Android API function android.os.Vibrator.vibrate

The function named in handlerFunctionName is called with one argument—the object that was shown.

Note: In Python scripts, you can specify the callback function to invoke by passing an actual function or a lambda function.

For examples see How to Use Event Handlers.

Note: The installEventHandler function will only work if it is called after the AUT has been started. For example, by using the ApplicationContext startApplication(autName) function.

uninstallEventHandler(eventName, handlerFunctionNameOrReference)

This function uninstalls an event handler that has been previously installed using installEventHandler(eventName, handlerFunctionNameOrReference).
