IntentSender


public class IntentSender
extends Object implements Parcelable

java.lang.Object
   ↳ android.content.IntentSender


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().

Summary

Nested classes

interface IntentSender.OnFinished

Callback interface for discovering when a send operation has completed. 

class IntentSender.SendIntentException

Exception thrown when trying to send through a PendingIntent that has been canceled or is otherwise no longer able to execute the request. 

Inherited constants

int CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

int PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel(Parcel, int): the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)".

Fields

CREATOR

Added in API level 4
public static final Creator<IntentSender> CREATOR

Public methods

describeContents

Added in API level 4
public 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(android.os.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. Value is either 0 or CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 4
public 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.

Parameters
otherObj Object: This value may be null.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getCreatorPackage

Added in API level 17
public String getCreatorPackage ()

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

getCreatorUid

Added in API level 17
public int getCreatorUid ()

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

Returns
int The uid of the PendingIntent, or -1 if there is none associated with it.

getCreatorUserHandle

Added in API level 17
public UserHandle getCreatorUserHandle ()

Return the user handle of the application that created this PendingIntent, that is the user under which you will actually be sending the Intent. The returned UserHandle is supplied by the system, so that an application can not spoof its user. See Process.myUserHandle() for more explanation of user handles.

Returns
UserHandle The user handle of the PendingIntent, or null if there is none associated with it.

getTargetPackage

Added in API level 9
Deprecated in API level 17
public String getTargetPackage ()

This method was deprecated in API level 17.
Renamed to getCreatorPackage().

Returns
String

hashCode

Added in API level 4
public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns
int a hash code value for this object.

readIntentSenderOrNullFromParcel

Added in API level 4
public static IntentSender readIntentSenderOrNullFromParcel (Parcel in)

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 Parcel: The Parcel containing the written Messenger.

Returns
IntentSender Returns the Messenger read from the Parcel, or null if null had been written.

sendIntent

Added in API level 4
public void sendIntent (Context context,
