ActivityManager

extend Object
This class gets information about activities, services, processes, and interrelationships.
Many methods in this class are used for debugging and process information. Please do not use it in a way that affects the execution behavior of the development application. These classes are called at the method level.
This class should only be used in special cases and should not be used in app development. But some methods are not limited to this. For example, ** isLowRamDevice () ** will detect if you are running on a device that is out of memory and will act accordingly. ** clearApplicationUserData () ** gives the app a data reset function.
Similarly, ** ActivityManager.AppTask ** and ** ActivityManager.RecentTaskInfo ** may use inner classes when using apps associated with the task stack.
However, in general, you should use the methods of this class only for testing and debugging purposes.
