requestLocationUpdates（），java.lang.RuntimeException-Android

Question

所以我有这个错误：

D/LocationManager: [LocationManager] requestLocationUpdates(), 
    java.lang.RuntimeException
        at android.location.LocationManager.requestLocationUpdates(LocationManager.java:893)
        at android.location.LocationManager.requestLocationUpdates(LocationManager.java:471)

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:807)

当我使用locationManager.requestLocationUpdates时。

代码如下：

locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) ==
                PackageManager.PERMISSION_GRANTED &&
                ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) ==
                        PackageManager.PERMISSION_GRANTED) {


            locationManager.requestLocationUpdates(
                    LocationManager.GPS_PROVIDER,
                    MINIMUM_TIME_BETWEEN_UPDATES,
                    MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
                    new MyLocationListener()
            );

        } else {
            ActivityCompat.requestPermissions(this, new String[]{
                            Manifest.permission.ACCESS_FINE_LOCATION,
                            Manifest.permission.ACCESS_COARSE_LOCATION},
                    TAG_CODE_PERMISSION_LOCATION);
        } 

有什么问题吗？

谢谢。
