Question

我读了其他类似的问题，但找不到解决方案。

我昨天实施了这个https://developers.google.com/android/reference/com/google/android/gms/location/SettingsApi，它运行正常。今天我不知道我在项目中搞砸了什么。当我输入片段并且位置被禁用时，会弹出要求我打开位置的窗口，但无论我点击多少次没有它都不会消失，或者如果我点击是我会进入logcat < / p> E/AndroidRuntime: FATAL EXCEPTION: main Process: name.company.newapp, PID: 23652 java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1000, result=-1, data=Intent { (has extras) }} to activity {name.company.newapp/name.company.newapp.HomeScreen}: java.lang.IllegalStateException: GoogleApiClient is not connected yet. at android.app.ActivityThread.deliverResults(ActivityThread.java:4054) at android.app.ActivityThread.handleSendResult(ActivityThread.java:4097) at android.app.ActivityThread.access$1400(ActivityThread.java:177) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1497) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:145) at android.app.ActivityThread.main(ActivityThread.java:5938) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1400) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1195) Caused by: java.lang.IllegalStateException: GoogleApiClient is not connected yet. at com.google.android.gms.internal.zzlh.zzb(Unknown Source) at com.google.android.gms.internal.zzli.zzb(Unknown Source) at com.google.android.gms.location.internal.zzd.requestLocationUpdates(Unknown Source) 正如我昨天所说的那样。 ..

来自GoogleApiClient#disconnect()方法的Google API参考：

public abstract void disconnect（）

关闭与Google Play服务的连接。调用此方法后，无法使用此客户端进行调用。

您正在使用onPause()方法断开客户端，因此只要您致电startResolutionForResult()，您的GoogleApiClient就不再有效了。您无需停止并重新启动客户端，就像取消注册并重新注册BroadcastReceiver一样。从同一页面的顶部开始：

您应该在Activity的onCreate(Bundle)方法中实例化一个客户端对象，然后在connect()和onStart()中disconnect()中调用onStop()，无论状态如何。
