This class was deprecated
in API level 35.
Slice framework has been deprecated, it will not receive any updates from
ERROR(/android.os.Build.VANILLA_ICE_CREAM)
and forward. If you are looking for a
framework that sends displayable data from one app to another, consider using
AppSearchManager
.
Class describing the structure of the data contained within a slice.
A data version contains a string which describes the type of structure and a revision which denotes this specific implementation. Revisions are expected to be backwards compatible and monotonically increasing. Meaning if a SliceSpec has the same type and an equal or lesser revision, it is expected to be compatible.
Apps rendering slices will provide a list of supported versions to the OS which
will also be given to the app. Apps should only return a Slice
with a
SliceSpec
that one of the supported SliceSpec
s provided
canRender(SliceSpec)
.

Public methods
canRender
public boolean canRender (SliceSpec candidate)
Indicates that this spec can be used to render the specified spec.
Rendering support is not bi-directional (e.g. Spec v3 can render Spec v2, but Spec v2 cannot render Spec v3).
Parameters | |
---|---|
candidate |
SliceSpec : candidate format of data.
This value cannot be null . |
Returns | |
---|---|
boolean |
true if versions are compatible. |

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(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
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
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons 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.

writeToParcel
public void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
dest |
Parcel : The Parcel in which the object should be written.
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 Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
