Users can choose to have spam calls silently rejected. To provide greater\ntransparency to users when they miss calls, information about these blocked\ncalls is logged in the call log. Using the Android 10 API eliminates the\nrequirement to obtain the\n[`READ_CALL_LOG`](/reference/android/Manifest.permission#READ_CALL_LOG)\npermission from the user in order to provide call screening and caller ID\nfunctionality.\n\nYou use a\n[`CallScreeningService`](/reference/android/telecom/CallScreeningService)\nimplementation to screen calls. Call the\n[`onScreenCall()`](/reference/android/telecom/CallScreeningService#onScreenCall(android.telecom.Call.Details))\nfunction for any new incoming or outgoing calls when the number is not in the\nuser's contact list. You can check the\n[`Call.Details`](/reference/android/telecom/Call.Details) object for information\nabout the call. Specifically, the\n[`getCallerNumberVerificationStatus()`](/reference/android/telecom/Call.Details#getCallerNumberVerificationStatus())\nfunction includes information from the network provider about the other number.\nIf the verification status failed, this is a good indication that the call is\nfrom an invalid number or a potential spam call. \n\nKotlin \n\n```kotlin\nclass ScreeningService : CallScreeningService() {\n // This function is called when an ingoing or outgoing call\n // is from a number not in the user's contacts list\n override fun onScreenCall(callDetails: Call.Details) {\n // Can check the direction of the call\n val isIncoming = callDetails.callDirection == Call.Details.DIRECTION_INCOMING\n\n if (isIncoming) {\n // the handle (e.g. phone number) that the Call is currently connected to\n val handle: Uri = callDetails.handle\n\n // determine if you want to allow or reject the call\n when (callDetails.callerNumberVerificationStatus) {\n Connection.VERIFICATION_STATUS_FAILED -\u003e {\n // Network verification failed, likely an invalid/spam call.\n }\n Connection.VERIFICATION_STATUS_PASSED -\u003e {\n // Network verification passed, likely a valid call.\n }\n else -\u003e {\n // Network could not perform verification.\n // This branch matches Connection.VERIFICATION_STATUS_NOT_VERIFIED.\n }\n }\n }\n }\n}\n```\n\nJava \n\n```java\nclass ScreeningService extends CallScreeningService {\n @Override\n public void onScreenCall(@NonNull Call.Details callDetails) {\n boolean isIncoming = callDetails.getCallDirection() == Call.Details.DIRECTION_INCOMING;\n\n if (isIncoming) {\n Uri handle = callDetails.getHandle();\n\n switch (callDetails.getCallerNumberVerificationStatus()) {\n case Connection.VERIFICATION_STATUS_FAILED:\n // Network verification failed, likely an invalid/spam call.\n break;\n case Connection.VERIFICATION_STATUS_PASSED:\n // Network verification passed, likely a valid call.\n break;\n default:\n // Network could not perform verification.\n // This branch matches Connection.VERIFICATION_STATUS_NOT_VERIFIED\n }\n }\n }\n}\n```\n\nSet the `onScreenCall()` function to call\n[`respondToCall()`](/reference/android/telecom/CallScreeningService#respondToCall(android.telecom.Call.Details,%20android.telecom.CallScreeningService.CallResponse))\nto tell the system how to respond to the new call. This function takes a\n[`CallResponse`](/reference/android/telecom/CallScreeningService.CallResponse)\nparameter that you can use to tell the system to block the call, reject it as if\nthe user did, or silence it. You can also tell the system to skip adding this\ncall to the device's call log altogether. \n\nKotlin \n\n```kotlin\n// Tell the system how to respond to the incoming call\n// and if it should notify the user of the call.\nval response = CallResponse.Builder()\n // Sets whether the incoming call should be blocked.\n .setDisallowCall(false)\n // Sets whether the incoming call should be rejected as if the user did so manually.\n .setRejectCall(false)\n // Sets whether ringing should be silenced for the incoming call.\n .setSilenceCall(false)\n // Sets whether the incoming call should not be displayed in the call log.\n .setSkipCallLog(false)\n // Sets whether a missed call notification should not be shown for the incoming call.\n .setSkipNotification(false)\n .build()\n\n// Call this function to provide your screening response.\nrespondToCall(callDetails, response)\n```\n\nJava \n\n```java\n// Tell the system how to respond to the incoming call\n// and if it should notify the user of the call.\nCallResponse.Builder response = new CallResponse.Builder();\n// Sets whether the incoming call should be blocked.\nresponse.setDisallowCall(false);\n// Sets whether the incoming call should be rejected as if the user did so manually.\nresponse.setRejectCall(false);\n// Sets whether ringing should be silenced for the incoming call.\nresponse.setSilenceCall(false);\n// Sets whether the incoming call should not be displayed in the call log.\nresponse.setSkipCallLog(false);\n// Sets whether a missed call notification should not be shown for the incoming call.\nresponse.setSkipNotification(false);\n\n// Call this function to provide your screening response.\nrespondToCall(callDetails, response.build());\n```\n\nYou must register the `CallScreeningService` implementation in the manifest\nfile with the appropriate intent filter and permission so the system can trigger\nit correctly. \n\n \u003cservice\n android:name=\".ScreeningService\"\n android:permission=\"android.permission.BIND_SCREENING_SERVICE\"\u003e\n \u003cintent-filter\u003e\n \u003caction android:name=\"android.telecom.CallScreeningService\" /\u003e\n \u003c/intent-filter\u003e\n \u003c/service\u003e"]]
