ServiceState

public class ServiceState
extends Object implements Parcelable

java.lang.Object
↳	android.telephony.ServiceState

Contains phone state and service related information. The following phone information is included in returned ServiceState:

Service state: IN_SERVICE, OUT_OF_SERVICE, EMERGENCY_ONLY, POWER_OFF
Duplex mode: UNKNOWN, FDD, TDD
Roaming indicator
Operator name, short name and numeric id
Network selection mode

For historical reasons this class is not declared as final; however, it should be treated as though it were final.

Public constructors

ServiceState

public ServiceState ()

Empty constructor

ServiceState

public ServiceState (ServiceState s)

Copy constructors

Parameters
`s`	`ServiceState`: Source service state

Construct a ServiceState object from the given parcel.

Parameters
`in`	`Parcel`

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.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

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.

Get an array of cell bandwidths (kHz) for the current serving cells

Returns
`int[]`	Current serving cell bandwidths

getChannelNumber

public int getChannelNumber ()

Returns
`boolean`	true if manual mode, false if automatic mode

getNetworkRegistrationInfoList

public List<NetworkRegistrationInfo> getNetworkRegistrationInfoList ()

Get all of the available network registration info.

Returns
`List<NetworkRegistrationInfo>`	List of `NetworkRegistrationInfo` This value cannot be `null`.

getOperatorAlphaLong

public String getOperatorAlphaLong ()

Get current registered operator name in long alphanumeric format. In GSM/UMTS, long format can be up to 16 characters long. In CDMA, returns the ERI text, if set. Otherwise, returns the ONS.

Returns
`String`	long name of operator, null if unregistered or unknown

getOperatorAlphaShort

public String getOperatorAlphaShort ()

Get current registered operator name in short alphanumeric format. In GSM/UMTS, short format can be up to 8 characters long.

getRoaming

public boolean getRoaming ()

Get current roaming indicator of phone (note: not just decoding from TS 27.007 7.2)

getState

public int getState ()

Get current voice service state

Returns
`int`

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(Object) 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(java.lang.Object) 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.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int`	a hash code value for this object.

isSearching

public boolean isSearching ()

This indicates whether the device is searching for service. This API reports the modem searching status for AccessNetworkConstants#TRANSPORT_TYPE_WWAN (cellular) service in either NetworkRegistrationInfo#DOMAIN_CS or NetworkRegistrationInfo#DOMAIN_PS. This API will not report searching status for AccessNetworkConstants#TRANSPORT_TYPE_WLAN.

Returns
`boolean`	`true` whenever the modem is searching for service.

setIsManualSelection

public void setIsManualSelection (boolean isManual)

Parameters
`isManual`	`boolean`

setOperatorName

public void setOperatorName (String longName, 
                String shortName, 
                String numeric)

Parameters
`longName`	`String`
`shortName`	`String`
`numeric`	`String`

setRoaming

public void setRoaming (boolean roaming)

Parameters
`roaming`	`boolean`

setState

public void setState (int state)

Parameters
`state`	`int`

setStateOff

public void setStateOff ()

setStateOutOfService

public void setStateOutOfService ()

toString

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String`	a string representation of the object.

writeToParcel

public void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`out`	`Parcel`: The Parcel in which the object should be written.
`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
