↳ | android.content.pm.ComponentInfo |
Base class containing information common to all application components
(ActivityInfo
, ServiceInfo
). This class is not intended
to be used by itself; it is simply here to share common definitions
between all application components. As such, it does not itself
implement Parcelable, but does provide convenience methods to assist
in the implementation of Parcelable in subclasses.

Fields
applicationInfo
public ApplicationInfo applicationInfo
Global information about the application/package this component is a part of.
attributionTags
public String[] attributionTags
Set of attribution tags that should be automatically applied to this component.
When this component represents an Activity
, Service
,
ContentResolver
or BroadcastReceiver
, each instance will
be automatically configured with Context#createAttributionContext
using the first attribution tag contained here.
Additionally, when this component represents a BroadcastReceiver
and the sender of a broadcast requires the receiver to hold one or more
specific permissions, those permission checks will be performed using
each of the attributions tags contained here.

enabled
public boolean enabled
Indicates whether or not this component may be instantiated. Note that this value can be
overridden by the one in its parent ApplicationInfo

Comes from android:exported
of the
<activity>, <receiver>, <service>, or
