public static class ActivityManager.RunningTaskInfo
extends Object
implements Parcelable
java.lang.Object | |
↳ | 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.

ComponentName baseActivity
The component launched as the first activity in the task. This can be considered the "application" of this task.
int numRunning
Number of activities that are currently running (not stopped and persisted) in this task.
Bitmap thumbnail
Thumbnail representation of the task's current state. Currently always null.
ComponentName topActivity
The activity component at the top of the history stack of the task. This is what the user is currently doing.
int describeContents ()
Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(Parcel, int)
, the return value of this method must include the CONTENTS_FILE_DESCRIPTOR
bit.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. |
void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
dest |
Parcel : The Parcel in which the object should be written. |
flags |
int : Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE . |
