我对 Google Play Services 6.1.71 没有任何问题(因为一切正常)，但对较新版本 (6.5.87) 则不同。

我已经知道 LocationClient 类在 6.5.87 Google Play Services 类中已被弃用，我对转换 old GeofenceDetection sample. 没有什么问题。

1. 我遇到的第一个问题是，对于新的 Play 服务，我没有找到用于处理控制台错误的 OnAddGeofencesResultListener 和 OnRemoveGeofencesResultListener；
2. 第二个问题(主要问题)是添加地理围栏点。当我尝试添加一个请求时，我收到了一个未决的无限期...

我修改的代码是:

最佳答案

要替换 OnAddGeofencesResultListener 使用 ResultCallback

LocationServices.GeofencingApi
  .addGeofences(mGoogleApiClient, mCurrentGeofences, mGeofencePendingIntent)
  .setResultCallback(new ResultCallback<Status>() {
    @Override
    public void onResult(Status status) {
      if (status.isSuccess()) {
        // Success
      }
    }
 });
