无法从 FusedLocationAPI 中删除更新

Question

我正在尝试获取位置更新并将其发送到挂起的意图，我已经有这项工作了。但是有一个按钮，当按下它时，我希望它停止获取位置更新，这是我的代码：

主活动

public class MainActivity extends Activity implements LocationListener, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {   
GoogleApiClient mGoogleClient;
PendingIntent pendingIntent;
LocationRequest locationRequest;
LocationServices locationServices;
...
protected void onStart() {
    super.onStart();
    mGoogleClient.connect();
}
@Override
protected void onStop() {
    LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleClient, pendingIntent);
    super.onStop();
}
@Override
public void onLocationChanged(Location location) {
    // this callback is invoked when location updates
}
@Override
public void onConnected(Bundle connectionHint) {
    try {
        locationRequest = LocationRequest.create()
                .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
                .setFastestInterval(30000)
                .setInterval(60000);
        pendingIntent = PendingIntent.getService(this, 0,
                new Intent(this, MyLocationHandler.class),
                PendingIntent.FLAG_UPDATE_CURRENT);
        LocationServices.FusedLocationApi.requestLocationUpdates(
                mGoogleClient, locationRequest, pendingIntent);
        //Toast.makeText(this, "Adding Toast", Toast.LENGTH_LONG).show();
    } catch (Exception e) {
        ...
    }
}
@Override
public void onConnectionSuspended(int cause) {
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
    // this callback will be invoked when the connection attempt fails
    if (connectionResult.hasResolution()) {
        // Google Play services can fix the issue
        // e.g. the user needs to enable it, updates to latest version
        // or the user needs to grant permissions to it
        try {
            connectionResult.startResolutionForResult(this, 0);
        } catch (IntentSender.SendIntentException e) {
            // it happens if the resolution intent has been canceled,
            // or is no longer able to execute the request
        }
    } else {
        // Google Play services has no idea how to fix the issue
    }
}
@Override
protected void onCreate(Bundle savedInstanceState) {
    try {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mGoogleClient = new GoogleApiClient.Builder(this, this, this)
                .addApi(LocationServices.API)
                .build();
         TrackBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                    bTrack = !bTrack;
                    CheckTrack();
                }
            }
        });
}
...
public void CheckTrack() {
    if (a == null) {
        a = tracker.getLocation();
    }
    if (bTrack) {
            mGoogleClient.connect();
    } else {
            DisconnectHandlerCheck.postDelayed(DisconnectRunnableCheck, 500);            }
    }
}
Handler DisconnectHandlerCheck = new Handler();
Runnable DisconnectRunnableCheck = new Runnable() {
@Override
public void run() {
    try {
        onStop();
    } catch (Exception e) {
        ...
    }
}
};
}

出于某种原因，即使在我断开 Google 客户端并删除更新后，代码也会继续调用 PendingIntent。

为什么是想法？

Answer 1

断开 mGoogleClient 的连接后，使用 pendingIntent.cancel（） 取消挂起的意图。它对我有用。

Answer 2

尝试使用 ：mGoogleClient.disconnect（）;在你的 onStop（）/method版本中。
