AssociationInfo

AssociationInfo
extends Object
implements
Parcelable
Details for a specific "association" that has been established between an app and companion
device.
An association gives an app the ability to interact with a companion device without needing to
acquire broader runtime permissions. An association only exists after the user has confirmed that
an app should have access to a companion device.

Fields
Public methods
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 o)
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 return
true
.
- It is symmetric: for any non-null reference values
x
and y
, x.equals(y)
should return true
if and only if
y.equals(x)
returns true
.
- It is transitive: for any non-null reference values
x
, y
, and z
, if
x.equals(y)
returns true
and
y.equals(z)
returns true
, then
x.equals(z)
should return true
.
- It is consistent: for any non-null reference values
x
and y
, multiple invocations of
x.equals(y)
consistently return true
or consistently return false
, provided no
information used in equals
comparisons on the
objects is modified.
- For any non-null reference value
x
,
x.equals(null)
should return false
.
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 |
o |
Object : the reference object with which to compare. |
Returns |
boolean |
true if this object is the same as the obj
argument; false otherwise. |
getAssociatedDevice
public AssociatedDevice getAssociatedDevice ()
Companion device that was associated. Note that this field is not persisted across sessions.
Device can be one of the following types:
Returns |
AssociatedDevice |
the companion device that was associated, or null if the device is
self-managed or this association info was retrieved from persistent storage. |
getDeviceId
public DeviceId getDeviceId ()
getDeviceMacAddress
public MacAddress getDeviceMacAddress ()
Returns |
MacAddress |
the MAC address of the device.
This value may be null . |
getDeviceProfile
public String getDeviceProfile ()
Returns |
String |
the companion device profile used when establishing this
association, or null if no specific profile was used. |
getDisplayName
public CharSequence getDisplayName ()
Returns |
CharSequence |
the display name of the companion device (optionally) provided by the companion
application.
This value may be null . |
getId
public int getId ()
Returns |
int |
the unique ID of this association record. |
getSystemDataSyncFlags
public int getSystemDataSyncFlags ()
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
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. |
isSelfManaged
public boolean isSelfManaged ()
Returns |
boolean |
whether the association is managed by the companion application it belongs to. |
toString
public String toString ()
Returns a string representation of the object.
Returns |
String |
a string representation of the object. |
writeToParcel
public void writeToParcel (Parcel dest,
int flags)
Flatten this object in to a Parcel.
