Class Overview

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.

Public Methods

public final int getBannerResource ()

Added in API level 20

Return the banner resource identifier to use for this component. If the component defines a banner, that is used; else, the application banner is used.

Returns
int The banner associated with this component.

public final int getIconResource ()

Return the icon resource identifier to use for this component. If the component defines an icon, that is used; else, the application icon is used.

Returns
int The icon associated with this component.

public final int getLogoResource ()

Added in API level 19

Return the logo resource identifier to use for this component. If the component defines a logo, that is used; else, the application logo is used.

Returns
int The logo associated with this component.

public boolean isEnabled ()

Added in API level 11

Return whether this component and its enclosing application are enabled.

Returns
boolean

public CharSequence loadLabel (PackageManager pm)

Parameters
pm A PackageManager from which the label can be loaded; usually the PackageManager from which you originally retrieved this item.
Returns
CharSequence Returns a CharSequence containing the item's label. If the item does not have a label, its name is returned.

public void writeToParcel (Parcel dest, int parcelableFlags)

Added in API level 1

Parameters
dest
parcelableFlags
