Java – how to implement video using connectionservice

I want to use the system application to realize video chat through connection service https://developer.android.com/reference/android/telecom/ConnectionService.html. Unfortunately, I can't find any examples or tutorials on how to do this That's what I did:

Registration service:

TelecomManager manager = (TelecomManager) getSystemService(TELECOM_SERVICE);
PhoneAccountHandle phoneAccountHandle = new PhoneAccountHandle(new    ComponentName(getBaseContext().getPackageName(),PhoneConnectionService.class.getName()),"myConnectionServiceId");
PhoneAccount.Builder builder = PhoneAccount.builder(phoneAccountHandle,Localization.localize(R.string.IDS_APP_NAME_SHORT));
builder.setCapabilities(PhoneAccount.CAPABILITY_CALL_PROVIDER | PhoneAccount.CAPABILITY_CONNECTION_MANAGER| PhoneAccount.CAPABILITY_VIDEO_CALLING );
PhoneAccount phoneAccount = builder.build();
manager.registerPhoneAccount(phoneAccount);

Call:

TelecomManager manager = (TelecomManager) context.getSystemService(TELECOM_SERVICE);
PhoneAccountHandle phoneAccountHandle = new PhoneAccountHandle(new ComponentName(context.getPackageName(),"estosConnectionServiceId");
Bundle test = new Bundle();
test.putParcelable(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE,phoneAccountHandle);
test.putInt(TelecomManager.EXTRA_START_CALL_WITH_VIDEO_STATE,VideoProfile.STATE_BIDIRECTIONAL);
test.putParcelable(TelecomManager.EXTRA_OUTGOING_CALL_EXTRAS,extras);
manager.placeCall(Uri.parse("tel:" + number),test);

My connectionservice was called

@Override
public Connection onCreateOutgoingConnection(PhoneAccountHandle connectionManagerPhoneAccount,ConnectionRequest request) {

    Connection conn = new MyAndroidCallConnection();
    conn.setAddress(request.getAddress(),PRESENTATION_ALLOWED);
    conn.setInitializing();
    conn.setVideoProvider(new MyVideoProvider());
    conn.setActive();

    return conn;
}

I put my video recorder into the connection required by the system The phone activity appears and shows me the call through the small camera sign, so the system knows what I want to do I now expect to call the videoprovider method from the system in some way to give me the surface of the video, etc., but no method is called Someone knows what I did wrong or where to find a good example of this topic

Solution

I just forgot to add conn.setvideostate (videoprofile. State_bidirectional); My connection is not just on placecall Now access the videoprovider as expected
