onConnected 在 Android 地理围栏上没有响应
onConnected does not respond on Android Geofence
当我运行sample codes for android geofence, It works well. However in order to implement geofence on my own project, I tried to set up it by myself. Firstly I add some codes on build.gradle file and manifest file as documentation说。然后我得到了我的应用程序的 SHA1 密钥并将其添加到 console.developers.google.com 页面以创建 API 密钥。最后我启用了 Google Maps Android API v2 和 Google Play Android Developer APIs。当我 运行 下面的代码时，即使 Google Api 客户端正在构建，mGoogleApiClient.isConnecting() 函数 returns true 但 mGoogleApiClient.isConnected() 函数returns 错误。
谁能告诉我哪里做错了？

连接，因为大多数网络进程是异步的，您的 mGoogleApiClient.connect() 不会立即发生。您需要使用侦听器来了解 GoogleApiClient 何时连接。如我所见，您添加了 ConnectionCallbacks 和 OnConnectionFailedListener 接口，但未根据需要使用它们。连接发生后应执行的代码必须在 ConnectionCallbacks.onConnected(Bundle) 方法中实现，该方法在您的 Activity 中覆盖，如下所示：
@Override
public void onConnected(Bundle bundle) {
Toast.makeText(this, "Connected!", Toast.LENGTH_SHORT).show();
}
此外，要激活 Geofencing，您还需要在 GoogleApiclient 连接后调用 LocationServices.GeofencingApi.addGeofences(GoogleApiClient, GeofencingRequest, PendingIntent)，即在 onConnected(Bundle) 中。并且不要忘记为地理围栏结果设置 ResultCallback（LocationServices.GeofencingApi.addGeofences(...).setResultCallback(resultCallback) - 监听器接口）。
