IntentSender

extends Object
implements Parcelable
java.lang.Object
   ↳ android.content.IntentSender

Class Overview

A description of an Intent and target action to perform with it. The returned object can be handed to other applications so that they can perform the action you described on your behalf at a later time.

By giving a IntentSender to another application, you are granting it the right to perform the operation you have specified as if the other application was yourself (with the same permissions and identity). As such, you should be careful about how you build the IntentSender: often, for example, the base Intent you supply will have the component name explicitly set to one of your own components, to ensure it is ultimately sent there and nowhere else.

A IntentSender itself is simply a reference to a token maintained by the system describing the original data used to retrieve it. This means that, even if its owning application's process is killed, the IntentSender itself will remain usable from other processes that have been given it. If the creating application later re-retrieves the same kind of IntentSender (same operation, same Intent action, data, categories, and components, and same flags), it will receive a IntentSender representing the same token if that is still valid.

Instances of this class can not be made directly, but rather must be created from an existing PendingIntent with PendingIntent.getIntentSender().

Public Methods
int describeContents()
Describe the kinds of special objects contained in this Parcelable's marshalled representation.
boolean equals(Object otherObj)
Comparison operator on two IntentSender objects, such that true is returned then they both represent the same operation from the same package.
String getTargetPackage()
Return the package name of the application that created this IntentSender, that is the identity under which you will actually be sending the Intent.
int hashCode()
Returns an integer hash code for this object.
static IntentSender readIntentSenderOrNullFromParcel(Parcel in)
Convenience function for reading either a Messenger or null pointer from a Parcel.
void sendIntent(Context context, int code, Intent intent, IntentSender.OnFinished onFinished, Handler handler)
Perform the operation associated with this IntentSender, allowing the caller to specify information about the Intent to use and be notified when the send has completed.
String toString()
Returns a string containing a concise, human-readable description of this object.
static void writeIntentSenderOrNullToParcel(IntentSender sender, Parcel out)
Convenience function for writing either a IntentSender or null pointer to a Parcel.
void writeToParcel(Parcel out, int flags)
Flatten this object in to a Parcel.

Constants

public static final Creator<IntentSender> CREATOR

Since: API Level 4

Public Methods

public int describeContents ()

Since: API Level 4

Describe the kinds of special objects contained in this Parcelable's marshalled representation.

Returns
  • a bitmask indicating the set of special object types marshalled by the Parcelable.

public boolean equals (Object otherObj)

Since: API Level 4

Comparison operator on two IntentSender objects, such that true is returned then they both represent the same operation from the same package.

Parameters
otherObj the object to compare this instance with.
Returns
  • true if the specified object is equal to this Object; false otherwise.

public String getTargetPackage ()

Since: API Level 9

Return the package name of the application that created this IntentSender, that is the identity under which you will actually be sending the Intent. The returned string is supplied by the system, so that an application can not spoof its package.

Returns
  • The package name of the PendingIntent, or null if there is none associated with it.

public int hashCode ()

Since: API Level 4

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Returns
  • this object's hash code.

public static IntentSender readIntentSenderOrNullFromParcel (Parcel in)

Since: API Level 4

Convenience function for reading either a Messenger or null pointer from a Parcel. You must have previously written the Messenger with writeIntentSenderOrNullToParcel(IntentSender, Parcel).

Parameters
in The Parcel containing the written Messenger.
Returns
  • Returns the Messenger read from the Parcel, or null if null had been written.

public void sendIntent (Context context, int code, Intent intent, IntentSender.OnFinished onFinished, Handler handler)

Since: API Level 4

Perform the operation associated with this IntentSender, allowing the caller to specify information about the Intent to use and be notified when the send has completed.

Parameters
context The Context of the caller. This may be null if intent is also null.
code Result code to supply back to the IntentSender's target.
intent Additional Intent data. See Intent.fillIn() for information on how this is applied to the original Intent. Use null to not modify the original Intent.
onFinished The object to call back on when the send has completed, or null for no callback.
handler Handler identifying the thread on which the callback should happen. If null, the callback will happen from the thread pool of the process.
Throws
IntentSender.SendIntentException Throws CanceledIntentException if the IntentSender is no longer allowing more intents to be sent through it.

public String toString ()

Since: API Level 4

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression: 

   getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Returns
  • a printable representation of this object.

public static void writeIntentSenderOrNullToParcel (IntentSender sender, Parcel out)

Since: API Level 4

Convenience function for writing either a IntentSender or null pointer to a Parcel. You must use this with readIntentSenderOrNullFromParcel(Parcel) for later reading it.

Parameters
sender The IntentSender to write, or null.
out Where to write the IntentSender.

public void writeToParcel (Parcel out, int flags)

Since: API Level 4

Flatten this object in to a Parcel.

Parameters
out The Parcel in which the object should be written.
flags Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
