应用程序终止后，Google附近的API后台扫描不起作用

问题描述

我有kontakt.io信标，并尝试使用附近的API编写后台扫描应用程序。

我使用此方法订阅邮件：

  SubscribeOptions options = new SubscribeOptions.Builder（）
 //查找附加到BLE信标的消息。请参阅
 // https://developers.google.com/beacons/ 
 .setStrategy（Strategy.BLE_ONLY）
 .build（）; 
 
 Nearby.Messages.subscribe（mGoogleApiClient，getPendingIntent（），options）
 .setResultCallback（new ResultCallback< Status>（）{
 @Override 
 public void onResult （@NonNull状态状态）{
 if（status.isSuccess（））{
 Log.i（TAG，订阅成功）; 
 mSubState = SubState.SUBSCRIBING; 
 //开始处理通知的后台服务
 getActivity（）。startService（getBackgroundSubscribeServiceIntent（））; 
} else {
 Log.i（TAG，无法订阅）; 
 handleUnsuccessfulNearbyResult（status）; 
} 
} 
}）; 
  

我的代码依据以下示例：

我正确接收邮件，但是当我杀了应用程序时，没有更多邮件来。

有没有办法在查杀应用程序后从附近获取消息？

解决方案

还没有真正尝试过使用其中一个，但是您是否考虑/使用？根据描述：

您可以创建一个 Service ，它会持续运行扫描，直到您选择停止/销毁它为止。文档本身已经有了创建启动服务的功能。只要仔细阅读。

希望这有助于某种方式。祝你好运。

I have kontakt.io beacon and I try to write application for background scanning with nearby API.

I use this method to subscribe messages:

SubscribeOptions options = new SubscribeOptions.Builder()
            // Finds messages attached to BLE beacons. See
            // https://developers.google.com/beacons/
            .setStrategy(Strategy.BLE_ONLY)
            .build();

    Nearby.Messages.subscribe(mGoogleApiClient, getPendingIntent(), options)
            .setResultCallback(new ResultCallback<Status>() {
                @Override
                public void onResult(@NonNull Status status) {
                    if (status.isSuccess()) {
                        Log.i(TAG, "subscribed successfully");
                        mSubState = SubState.SUBSCRIBING;
                        // Start background service for handling the notification.
                        getActivity().startService(getBackgroundSubscribeServiceIntent());
                    } else {
                        Log.i(TAG, "could not subscribe");
                        handleUnsuccessfulNearbyResult(status);
                    }
                }
            });

My code is according to this sample:https://github.com/googlesamples/android-nearby/tree/master/messages/NearbyBackgroundBeacons

I´m receiving messages correctly, but when I kill application no more message come.

Is there any way to get messages from nearby after killing application?

解决方案

Haven't really tried using one yet, but have you considered/checked on using a Service? As per the description:

You could create a Service that runs the scan continuously until such time that you choose to stop/destroy it. The docs itself already has step on Creating a Started Service. Just read it thoroughly.

Hope this helps somehow. Good luck.
