Android 安卓-如何每10米更新一次位置？

在我的应用程序中，我必须更新每10米行程的具体数据。 为此，我使用LocationManager获取更新，但没有得到正确的答案

我使用了以下代码：还添加了权限粗糙，精细，互联网

locationManager.requestLocationUpdates(getProviderName(), 10000,
            10, locationListener);

private String getProviderName() {
    LocationManager locationManager = (LocationManager) this
            .getSystemService(Context.LOCATION_SERVICE);

    Criteria criteria = new Criteria();
    criteria.setPowerRequirement(Criteria.POWER_LOW);
    // criteria.setAccuracy(Criteria.ACCURACY_FINE);
    criteria.setSpeedRequired(true);
    criteria.setAltitudeRequired(true);
    criteria.setBearingRequired(true);
    criteria.setCostAllowed(false);
    criteria.setAccuracy(Criteria.ACCURACY_MEDIUM);
    criteria.setSpeedAccuracy(Criteria.ACCURACY_MEDIUM);
    criteria.setBearingAccuracy(Criteria.ACCURACY_MEDIUM);

    return locationManager.getBestProvider(criteria, true);
}

此条件是否表示LocationManager在10米范围内每隔10秒更新一次？我说得对吗

您需要的只是您的主要活动（或您正在使用该位置的任何活动）：

要获取位置，请执行以下操作：

GPSTracker gpsTracker = new GPSTracker(this);

gpsTracker.getLatitude();
gpsTracker.getLongitude();
