Cordova Android Pay Wallet Request Returns Nothing

Question

I am trying to write a plugin that will check if Android Pay is setup on the users phone. I have followed the Android tutorial with their sample code but can't get it to work with Cordova. When the function canMakePayments is called from the sample below, nothing happens. I do not see a failure or success come back from the call to Wallet.Payments.isReadyToPay. Any advise would be much appreciated.

It wasn't in the developer documentation but what fixed this for me was to make a connect call to the google client before calling Wallet.Payments.isReadyToPay

mGoogleApiClient = new GoogleApiClient.Builder(this.cordova.getActivity())
                                .addApi(Wallet.API, new Wallet.WalletOptions.Builder()
                                    .setEnvironment(WALLET_ENVIRONMENT)
                                    .build())
                                .addConnectionCallbacks(this)
                                .addOnConnectionFailedListener(this)                            
                                .build();               

// Connect to google api client
mGoogleApiClient.connect();
