extends Object
implements
Parcelable
| java.lang.Object | |
| ↳ | android.app.HandoffActivityData |
Represents information needed to recreate an activity on a remote device owned by the user.
This class is returned by Activity.onHandoffActivityDataRequested, and is passed to a
remote device owned by the user. The remote device will create a launch intent for the activity
specified by getComponentName(), passing along any extras specified by getExtras().
If getComponentName() cannot be launched on the remote device, developers can
optionally specify a fallback URI in ERROR(/#setFallbackUri()). The URI specified will be
launched on the remote device's web browser in this case. If no fallback URI is specified, the
user will be presented with an error. If the system is attempting to hand off the entire task,
failure to resolve getComponentName() will result in only the top activity of the task
being handed off. It is also possible to simply specify a fallback URI, rather than specifying a
component name.

createWebHandoff
public static HandoffActivityData createWebHandoff (Uri uri)
Creates a HandoffActivityData object for a web handoff.
| Parameters | |
|---|---|
uri |
Uri: the URI to be launched on the remote device's web browser.
This value cannot be null. |
| Returns | |
|---|---|
HandoffActivityData |
the HandoffActivityData object.
This value cannot be null. |
describeContents
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(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

equals
public boolean equals (Object obj)
Indicates whether some other object is "equal to" this one.
The equals method implements an equivalence relation
on non-null object references:
- It is reflexive: for any non-null reference value
x,x.equals(x)should returntrue. - It is symmetric: for any non-null reference values
xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue. - It is consistent: for any non-null reference values
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified. - For any non-null reference value
x,x.equals(null)should returnfalse.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
| Parameters | |
|---|---|
obj |
Object: the reference object with which to compare. |
| Returns | |
|---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
getComponentName
public ComponentName getComponentName ()
| Returns | |
|---|---|
ComponentName |
the component name of an activity to launch on the remote device when the activity
represented by this object is handed off. When this is null, the getFallbackUri() will be used. |
getExtras
public PersistableBundle getExtras ()
| Returns | |
|---|---|
PersistableBundle |
extras to pass inside the launch intent via ERROR(/Intent#putExtras) for the activity
specified by getComponentName() during handoff. This defaults to an empty
bundle.
This value cannot be null. |
getFallbackUri
public Uri getFallbackUri ()
| Returns | |
|---|---|
Uri |
the URI which will be launched on the remote device's web browser if the activity
specified by getComponentName() cannot be launched, or null if no
fallback URI was specified. |
hashCode
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
hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons 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
equalsmethod, then calling thehashCodemethod 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
equalsmethod, then calling thehashCodemethod 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. |
writeToParcel
public void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
| Parameters | |
|---|---|
dest |
Parcel: This value cannot be null. |
flags |
int: Additional flags about how the object should be written.
May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
Value is either 0 or a combination of the following:
