AbstractBankCallVerificationService

Kotlin |Java

public abstract class AbstractBankCallVerificationService extends Service

java.lang.Object
↳	android.content.Context
	↳	android.content.ContextWrapper
		↳	android.app.Service
			↳	com.google.android.gms.fraudprotect.AbstractBankCallVerificationService

Abstract class for a bound service that a Bank App should extend to integrate with the Google Play services phone spoofing prevention feature.

To implement this service, extend this class and override the onVerifyCall method. Optionally, override onEvent to handle events from Google Play services. Declare the service in your AndroidManifest.xml, ensuring it is protected by the com.google.android.gms.fraudprotect.permission.CALL_VALIDATION_SERVICE permission and includes an <intent-filter> for the action AbstractBankCallVerificationService.SERVICE_ACTION.

Example manifest declaration:

<service
    android:name=".YourBankCallVerificationService"
    android:exported="true"
    android:permission="com.google.android.gms.fraudprotect.permission.CALL_VALIDATION_SERVICE">
    <intent-filter>
        <action android:name="com.google.android.gms.fraudprotect.ACTION_VERIFY_CALL" />
    </intent-filter>
</service>

Constants

SERVICE_ACTION

public static final @NonNull String SERVICE_ACTION

The Intent action that must be declared in the <intent-filter> of this service in the AndroidManifest.xml.

Public constructors

AbstractBankCallVerificationService

public AbstractBankCallVerificationService()

Public methods

onBind

public IBinder onBind(@NonNull Intent intent)

Returns the communication channel IBinder to the service.

Protected methods

onEvent

protected void onEvent(@NonNull String requestId, @NonNull CallVerificationEvent event)

Called when Google Play services sends an event regarding the call verification process.

A Bank App can override this method to log or react to CallVerificationEvent updates from Google Play services, such as timeouts or confirmations of actions taken (for example, call ended). The default implementation is a no-op.

Parameters
`@NonNull String requestId`	The unique identifier for the original verification request.
`@NonNull CallVerificationEvent event`	The `CallVerificationEvent` object containing details about the event.

onVerifyCall

protected abstract void onVerifyCall(
    @NonNull String requestId,
    @NonNull String incomingNumber,
    @NonNull List<@NonNull String> userPhoneNumbersSuffixes,
    @NonNull AbstractBankCallVerificationService.VerdictSubmitter submitter
)

Abstract method to be implemented by the Bank App. This method is called by Google Play services when an incoming call from a number registered with the Bank is detected.

The implementation should perform the necessary checks (potentially involving backend systems) to determine if the call is legitimate for the current user context. Once a determination is made, the result MUST be sent back using the provided VerdictSubmitter.submit method.

This method is called on a Binder thread. Implementations should offload any long-running operations (like network requests) to a background thread to avoid blocking the Binder thread and potentially causing Application Not Responding (ANR) errors. The VerdictSubmitter object can be safely used from a background thread.

Parameters
`@NonNull String requestId`	A unique identifier for this specific verification request. Use this for logging or correlation if needed.
`@NonNull String incomingNumber`	The `E.164` formatted phone number of the incoming call.
`@NonNull List<@NonNull String> userPhoneNumbersSuffixes`	A list of phone number suffixes associated with the SIM(s) on the user's device. This list may be empty if the user's phone number(s) cannot be determined.
`@NonNull AbstractBankCallVerificationService.VerdictSubmitter submitter`	The interface to invoke to return the verdict to Google Play services.
