extends Object
implements
RegistrationManager
| java.lang.Object | |
| ↳ | android.telephony.ims.ImsMmTelManager |
A manager for the MmTel (Multimedia Telephony) feature of an IMS network, given an associated
subscription.
Allows a user to query the IMS MmTel feature information for a subscription, register for
registration and MmTel capability status callbacks, as well as query/modify user settings for the
associated subscription.
Use ImsManager.getImsMmTelManager(int) to get an instance of this
manager.
Requires the PackageManager#FEATURE_TELEPHONY_IMS feature which can be detected using PackageManager.hasSystemFeature(String).

Public methods
getRegistrationTransportType
public void getRegistrationTransportType (Executor executor, Consumer<Integer> transportTypeCallback)
Requires Permission: READ_PRECISE_PHONE_STATE or that the calling app has carrier privileges
(see TelephonyManager.hasCarrierPrivileges()).
Access by profile owners is deprecated and will be removed in a future release.

Requires android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE or Manifest.permission.READ_PRECISE_PHONE_STATE
| Parameters | |
|---|---|
executor |
Executor: This value cannot be null.
Callback and listener events are dispatched through this
Executor, providing an easy way to control which thread is
used. To dispatch events through the main thread of your
application, you can use

This API requires one of the following:
- The caller holds the READ_PRECISE_PHONE_STATE permission.
- If the caller is the device or profile owner, the caller holds the
Manifest.permission.READ_PRECISE_PHONE_STATEpermission. - The caller has carrier privileges (see
TelephonyManager.hasCarrierPrivileges()) on any active subscription.
The profile owner is an app that owns a managed profile on the device; for more details
see Work profiles.

Requires android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE or Manifest.permission.READ_PRECISE_PHONE_STATE
| Returns | |
|---|---|
int |
The Voice over WiFi Mode preference set by the user, which can be one of the
following:

- WIFI_MODE_CELLULAR_PREFERRED
- WIFI_MODE_WIFI_PREFERRED
Value is android.telephony.ims.ImsMmTelManager.WIFI_MODE_UNKNOWN, WIFI_MODE_WIFI_ONLY, WIFI_MODE_CELLULAR_PREFERRED, or WIFI_MODE_WIFI_PREFERRED |
| Throws | |

isAdvancedCallingSettingEnabled
public boolean isAdvancedCallingSettingEnabled ()
Query the user\u2019s setting for \u201cAdvanced Calling\u201d or "Enhanced 4G LTE", which is used to enable MmTel IMS features, depending on the carrier configuration for the current subscription. If this setting is enabled, IMS voice and video telephony over IWLAN/LTE will be enabled as long as the carrier has provisioned these services for the specified subscription. Other IMS services (SMS/UT) are not affected by this user setting and depend on carrier requirements.
Note: If the carrier configuration for advanced calling is not editable or hidden, this method will always return the default value.
This API requires one of the following:
- The caller holds the READ_PRECISE_PHONE_STATE permission.
- If the caller is the device or profile owner, the caller holds the
Manifest.permission.READ_PRECISE_PHONE_STATEpermission. - The caller has carrier privileges (see
TelephonyManager.hasCarrierPrivileges()) on any active subscription.
The profile owner is an app that owns a managed profile on the device; for more details
see Work profiles.

UnsupportedOperationException |
If the device does not have
PackageManager.FEATURE_TELEPHONY_IMS. |
isCrossSimCallingEnabled
public boolean isCrossSimCallingEnabled ()
This configuration is meaningful only on dual sim device.
If enabled, this will result in the device setting up IMS of all other
active subscriptions over the INTERNET APN of the primary default data subscription
when any of those subscriptions are roaming or out of service and if wifi is not available
