科尔多瓦Android Pay电子钱包请求未返回任何内容

Question

我正在尝试编写一个插件，以检查用户手机上是否设置了Android Pay。 我已经按照Android教程的示例代码进行了操作，但是无法使其与Cordova一起使用。 当从下面的示例中调用canMakePayments函数时，什么也不会发生。 从Wallet.Payments.isReadyToPay的调用中看不到失败或成功。 任何建议将不胜感激。

它不在开发人员文档中，但对我而言，解决此问题的方法是在调用Wallet.Payments.isReadyToPay之前先对Google客户端进行连接调用

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();
