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.

Fields

public ApplicationInfo applicationInfo

Since: API Level 1

Global information about the application/package this component is a part of.

public boolean enabled

Since: API Level 1

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

public boolean exported

Since: API Level 1

Set to true if this component is available for use by other applications. Comes from android:exported of the <activity>, <receiver>, <service>, or <provider> tag.

public String processName

Since: API Level 1

The name of the process this component should run in. From the "android:process" attribute or, if not set, the same as applicationInfo.processName.

Public Constructors

public ComponentInfo ()

Since: API Level 1

public ComponentInfo (ComponentInfo orig)

Since: API Level 1

Protected Constructors

protected ComponentInfo (Parcel source)

Since: API Level 1

Public Methods

public final int getIconResource ()

Since: API Level 1

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
  • The icon associated with this component.

public Drawable loadIcon (PackageManager pm)

Since: API Level 1

Retrieve the current graphical icon associated with this item. This will call back on the given PackageManager to load the icon from the application.

Parameters
pm A PackageManager from which the icon can be loaded; usually the PackageManager from which you originally retrieved this item.
Returns
  • Returns a Drawable containing the item's icon. If the item does not have an icon, the default activity icon is returned.

public CharSequence loadLabel (PackageManager pm)

Since: API Level 1

Retrieve the current textual label associated with this item. This will call back on the given PackageManager to load the label from the application.

Parameters
pm A PackageManager from which the label can be loaded; usually the PackageManager from which you originally retrieved this item.
Returns
  • 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)

Since: API Level 1

Protected Methods

protected void dumpBack (Printer pw, String prefix)

Since: API Level 1

protected void dumpFront (Printer pw, String prefix)

Since: API Level 1
