| ↳ | android.telecom.TelecomManager |
Provides access to information about active calls and registration/call-management functionality. Apps can use methods in this class to determine the current call state.
Apps do not instantiate this class directly; instead, they retrieve a reference to an instance
through Context.getSystemService(Context.TELECOM_SERVICE).
Note that access to some telecom information is permission-protected. Your app cannot access the protected information or gain access to protected functionality unless it has the appropriate permissions declared in its manifest file. Where permissions apply, they are noted in the method descriptions.
