Remarks

Set a SignalStrengthUpdateRequest to receive notification when signal quality measurements breach the specified thresholds.

To be notified, set the signal strength update request and then register TelephonyManager#listen(PhoneStateListener, int) with PhoneStateListener#LISTEN_SIGNAL_STRENGTHS. The notification will arrive through PhoneStateListener#onSignalStrengthsChanged(SignalStrength).

To stop receiving the notification over the specified thresholds, pass the same SignalStrengthUpdateRequest object to #clearSignalStrengthUpdateRequest(SignalStrengthUpdateRequest).

System will clean up the SignalStrengthUpdateRequest if the caller process died without calling #clearSignalStrengthUpdateRequest(SignalStrengthUpdateRequest).

If this TelephonyManager object has been created with #createForSubscriptionId, applies to the given subId. Otherwise, applies to SubscriptionManager#getDefaultSubscriptionId(). To request for multiple subIds, pass a request object to each TelephonyManager object created with #createForSubscriptionId.

Requires Permission: android.Manifest.permission#MODIFY_PHONE_STATE MODIFY_PHONE_STATE or that the calling app has carrier privileges (see TelephonyManager#hasCarrierPrivileges).

Note that the thresholds in the request will be used on a best-effort basis; the system may modify requests to multiplex various request sources or to optimize power consumption. The caller should not expect to be notified with the exactly the same thresholds.
