extends Object
implements Parcelable

   ↳ android.app.ActivityManager.RunningTaskInfo

Class Overview

Information you can retrieve about a particular task that is currently "running" in the system. Note that a running task does not mean the given task actually has a process it is actively running in; it simply means that the user has gone to it and never closed it, but currently the system may have killed its process and is only holding on to its last state in order to restart it when the user returns.
