Examples with NetworkRegistrationInfo android.telephony.NetworkRegistrationInfo used on opensource projects

Example 1 with NetworkRegistrationInfo

use of android.telephony.NetworkRegistrationInfo in project Resurrection_packages_apps_Settings by ResurrectionRemix.

the class NetworkSelectSettings method forceUpdateConnectedPreferenceCategory.

/**
 * Config the connected network operator preference when the page was created. When user get
 * into this page, the device might or might not have data connection.
 * - If the device has data:
 * 1. use {@code ServiceState#getNetworkRegistrationInfoList()} to get the currently
 * registered cellIdentity, wrap it into a CellInfo;
 * 2. set the signal strength level as strong;
 * 3. get the title of the previously connected network operator, since the CellIdentity
 * got from step 1 only has PLMN.
 * - If the device has no data, we will remove the connected network operators list from the
 * screen.
