RunningTaskInfo

---

Kotlin |Java

open class RunningTaskInfo : TaskInfo, Parcelable

kotlin.Any
↳	android.app.TaskInfo
	↳	android.app.ActivityManager.RunningTaskInfo

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.

Summary

Inherited constants

From class Parcelable Int CONTENTS_FILE_DESCRIPTOR Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor. Int PARCELABLE_WRITE_RETURN_VALUE Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

Inherited properties

From class TaskInfo ComponentName? baseActivity The component of the first activity in the task, can be considered the "application" of this task. Intent baseIntent The base intent of the task (generally the intent that launched the task). This intent can be used to relaunch the task (if it is no longer running) or brought to the front if it is. Boolean isRunning Whether or not this task has any running activities. Int numActivities The number of activities in this task (including running). ComponentName? origActivity The component of the target activity if this task was started from an activity alias. Otherwise, this is null. ActivityManager.TaskDescription? taskDescription The recent activity values for the highest activity in the stack to have set the values. Activity.setTaskDescription(android.app.ActivityManager.TaskDescription). Int taskId The identifier for this task. ComponentName? topActivity The component of the top activity in the task, currently showing to the user.
