Constants
CONNECTION_NONE
public static final int CONNECTION_NONE
Cell is not a serving cell.
The cell has been measured but is neither a camped nor serving cell (3GPP 36.304).
Constant Value: 0 (0x00000000)
CONNECTION_PRIMARY_SERVING
public static final int CONNECTION_PRIMARY_SERVING
UE is connected to cell for signalling and possibly data (3GPP 36.331, 25.331).
Constant Value: 1 (0x00000001)
CONNECTION_SECONDARY_SERVING
public static final int CONNECTION_SECONDARY_SERVING
UE is connected to cell for data (3GPP 36.331, 25.331).
Constant Value: 2 (0x00000002)
CONNECTION_UNKNOWN
public static final int CONNECTION_UNKNOWN
Connection status is unknown.
Constant Value: 2147483647 (0x7fffffff)
UNAVAILABLE
public static final int UNAVAILABLE
This value indicates that the integer field is unreported.
Constant Value: 2147483647 (0x7fffffff)
UNAVAILABLE_LONG
public static final long UNAVAILABLE_LONG
This value indicates that the long field is unreported.
Constant Value: 9223372036854775807 (0x7fffffffffffffff)

Public methods
describeContents
public int describeContents ()
Implement the Parcelable interface
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 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.
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. |
getCellConnectionStatus
public int getCellConnectionStatus ()
Gets the connection status of this cell.
Returns | |
---|---|
int |
The connection status of the cell.
Value is CONNECTION_NONE , CONNECTION_PRIMARY_SERVING , CONNECTION_SECONDARY_SERVING , or CONNECTION_UNKNOWN |
getCellIdentity
public abstract CellIdentity getCellIdentity ()
Returns | |
---|---|
CellIdentity |
a CellIdentity instance.
This value cannot be null . |
getCellSignalStrength
public abstract CellSignalStrength getCellSignalStrength ()
Returns | |
---|---|
CellSignalStrength |
a CellSignalStrength instance.
This value cannot be null . |
getTimeStamp
public long getTimeStamp ()
This method was deprecated
in API level 30.
Use getTimestampMillis()
instead.
Approximate time this cell information was received from the modem.
Returns | |
---|---|
long |
a time stamp in nanos since boot. |
getTimestampMillis
public long getTimestampMillis ()
Approximate time this cell information was received from the modem.
Value is a non-negative timestamp in the
SystemClock.elapsedRealtime()
time base.
Returns | |
---|---|
long |
a time stamp in millis since boot.
Value is a non-negative timestamp in the
SystemClock.elapsedRealtime() time base. |
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 inequals
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 thehashCode
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 thehashCode
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. |
isRegistered
public boolean isRegistered ()
True if the phone is registered to a mobile network that provides service on this cell and this cell is being used or would be used for network signaling.
Returns | |
---|---|
boolean |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of the object. |
writeToParcel
public abstract void writeToParcel (Parcel dest, int flags)
Implement the Parcelable interface
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 |
