| ↳ | android.telephony.TelephonyManager |
Provides access to information about the telephony services on the device. Applications can use the methods in this class to determine telephony services and states, as well as to access some types of subscriber information. Applications can also register a listener to receive notification of telephony state changes.
You do not instantiate this class directly; instead, you retrieve
a reference to an instance through
Context.getSystemService(Context.TELEPHONY_SERVICE).
Note that access to some telephony information is permission-protected. Your application cannot access the protected information unless it has the appropriate permissions declared in its manifest file. Where permissions apply, they are noted in the the methods through which you access the protected information.

Broadcast intent action indicating that the call state (cellular) on the device has changed.
The EXTRA_STATE extra indicates the new call state.
If the new state is RINGING, a second extra
EXTRA_INCOMING_NUMBER provides the incoming phone number as
a String.
Requires the READ_PHONE_STATE permission.
This was a sticky
broadcast in version 1.0, but it is no longer sticky.
Instead, use getCallState() to synchronously query the current call state.
The Phone app sends this intent when a user opts to respond-via-message during an incoming
call. By default, the device's default SMS app consumes this message and sends a text message
to the caller. A third party app can also provide this functionality by consuming this Intent
with a Service and sending the message using its own messaging system.
The intent contains a URI (available from getData())
describing the recipient, using either the sms:, smsto:, mms:,
or mmsto: URI schema. Each of these URI schema carry the recipient information the
same way: the path part of the URI contains the recipient's phone number or a comma-separated
set of phone numbers if there are multiple recipients. For example, smsto:2065551234.
The intent may also contain extras for the message text (in EXTRA_TEXT) and a message subject
(in EXTRA_SUBJECT).
Note:
The intent-filter that consumes this Intent needs to be in a Service
that requires the
permission SEND_RESPOND_VIA_MESSAGE.
For example, the service that receives this intent can be declared in the manifest file with an intent filter like this:
<!-- Service that delivers SMS messages received from the phone "quick response" -->
<service android:name=".HeadlessSmsSendService"
android:permission="android.permission.SEND_RESPOND_VIA_MESSAGE"
android:exported="true" >
<intent-filter>
<action android:name="android.intent.action.RESPOND_VIA_MESSAGE" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="sms" />
<data android:scheme="smsto" />
<data android:scheme="mms" />
<data android:scheme="mmsto" />
</intent-filter>
</service>
Output: nothing.
Device call state: No activity.
Device call state: Off-hook. At least one call exists that is dialing, active, or on hold, and no calls are ringing or waiting.
Device call state: Ringing. A new call arrived and is ringing or waiting. In the latter case, another call is already active.

Returns all observed cell information from all radios on the device including the primary and neighboring cells. This does not cause or change the rate of PhoneStateListner#onCellInfoChanged.
The list can include one or more of CellInfoGsm,
CellInfoCdma,
CellInfoLte and
CellInfoCdma in any combination.
Specifically on devices with multiple radios it is typical to see instances of
one or more of any these in the list. In addition 0, 1 or more CellInfo
objects may return isRegistered() true.
This is preferred over using getCellLocation although for older devices this may return null in which case getCellLocation should be called.
Requires Permission: ACCESS_COARSE_LOCATION
Returns a constant indicating the call state (cellular) on the device.
Returns the current location of the device.
If there is only one radio in the device and that radio has an LTE connection, this method will return null. The implementation must not to try add LTE identifiers into the existing cdma/gsm classes.
In the future this call will be deprecated.

Registers a listener object to receive notification of changes in specified telephony states.
To register a listener, pass a PhoneStateListener
and specify at least one telephony state of interest in
the events argument.
At registration, and when a specified telephony state
changes, the telephony manager invokes the appropriate
callback method on the listener object and passes the
current (updated) values.
To unregister a listener, pass the listener object and set the
events argument to
LISTEN_NONE (0).
| listener | The PhoneStateListener object to register
(or unregister) |
|---|---|
| events | The telephony state(s) of interest to the listener,
as a bitwise-OR combination of PhoneStateListener
LISTEN_ flags.
