Java 无法从FusedLocationApi中删除更新
我正试图获得位置更新,并将其发送到一个待定的意图,我已经有了这项工作的罚款。但是有一个按钮,当它按下时,我希望它停止获取位置更新,以下是我的代码: 主要活动Java 无法从FusedLocationApi中删除更新,java,android,google-api,Java,Android,Google Api,我正试图获得位置更新,并将其发送到一个待定的意图,我已经有了这项工作的罚款。但是有一个按钮,当它按下时,我希望它停止获取位置更新,以下是我的代码: 主要活动 public class MainActivity extends Activity implements LocationListener, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener { GoogleApiClien

出于某种原因,即使在我断开Google客户端并删除更新后,代码仍会继续调用PendingEvent
为什么有想法?尝试使用:
mGoogleClient.disconnect;
在您的onStop/method版本中。断开mGoogleClient后,使用PendingContent.cancel取消挂起的意图。它对我有用
