Remarks

This service can be implemented by the default dialer (see TelecomManager#getDefaultDialerPackage()) or a third party app to allow or disallow incoming calls before they are shown to a user. A CallScreeningService can also see outgoing calls for the purpose of providing caller ID services for those calls.

Below is an example manifest registration for a CallScreeningService.

{@code
<service android:name="your.package.YourCallScreeningServiceImplementation"
                     android:permission="android.permission.BIND_SCREENING_SERVICE">
<intent-filter>
<action android:name="android.telecom.CallScreeningService"/>
</intent-filter>
</service>
            }

A CallScreeningService performs two functions: <ol> <li>Call blocking/screening - the service can choose which calls will ring on the user's device, and which will be silently sent to voicemail.</li> <li>Call identification - services which provide call identification functionality can display a user-interface of their choosing which contains identifying information for a call. </li> </ol>

<h2>Becoming the CallScreeningService</h2> Telecom will bind to a single app chosen by the user which implements the CallScreeningService API when there are new incoming and outgoing calls.

The code snippet below illustrates how your app can request that it fills the call screening role.

{@code
            private static final int REQUEST_ID = 1;

            public void requestRole() {
                RoleManager roleManager = (RoleManager) getSystemService(ROLE_SERVICE);
                Intent intent = roleManager.createRequestRoleIntent(RoleManager.ROLE_CALL_SCREENING);
                startActivityForResult(intent, REQUEST_ID);
            }

            &#64;Override
            public void onActivityResult(int requestCode, int resultCode, Intent data) {
                if (requestCode == REQUEST_ID) {
                    if (resultCode == android.app.Activity.RESULT_OK) {
                        // Your app is now the call screening app
                    } else {
                        // Your app is not the call screening app
                    }
                }
            }
            }

<h2>CallScreeningService Lifecycle</h2>

The framework binds to the CallScreeningService implemented by the user-chosen app filling the android.app.role.RoleManager#ROLE_CALL_SCREENING role when incoming calls are received (prior to ringing) and when outgoing calls are placed. The platform calls the #onScreenCall(Call.Details) method to provide your service with details about the call.

For incoming calls, the CallScreeningService must call #respondToCall(Call.Details, CallResponse) within 5 seconds of being bound to indicate to the platform whether the call should be blocked or not. Your app must do this even if it is primarily performing caller ID operations and not screening calls. It is important to perform screening operations in a timely matter as the user's device will not begin ringing until the response is received (or the timeout is hit). A CallScreeningService may choose to perform local database lookups to help determine if a call should be screened or not; care should be taken to ensure the timeout is not repeatedly hit, causing delays in the incoming call flow.

If your app provides a caller ID experience, it should launch an activity to show the caller ID information from #onScreenCall(Call.Details).
