java - 如何在可以运行直到用户停止的服务中创建 FusedLocationProviderClient？

Question

我已经成功创建了一个带有 的 Activity FusedLocationProviderClient 返回特定时间段内的位置坐标。

但我希望它在后台服务中运行，该服务将坐标保存在本地数据库中，并且在用户手动停止服务之前永远不会结束。

这是我的源代码:

private String mLastUpdateTime;
private static final long UPDATE_INTERVAL_IN_MILLISECONDS = 10000;
private static final long FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS = 5000;
private static final int REQUEST_CHECK_SETTINGS = 100;
private FusedLocationProviderClient mFusedLocationClient;
private SettingsClient mSettingsClient;
private LocationRequest mLocationRequest;
private LocationSettingsRequest mLocationSettingsRequest;
private LocationCallback mLocationCallback;
private Location mCurrentLocation;

private void init() {
    mFusedLocationClient = 
   LocationServices.getFusedLocationProviderClient(this);
    mSettingsClient = LocationServices.getSettingsClient(this);

    mLocationCallback = new LocationCallback() {
        @Override
        public void onLocationResult(LocationResult locationResult) {
            super.onLocationResult(locationResult);
            // location is received
            mCurrentLocation = locationResult.getLastLocation();
            mLastUpdateTime = DateFormat.getTimeInstance().format(new Date());

            updateUIAndMarker();
        }
    };

    mRequestingLocationUpdates = false;

    mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(UPDATE_INTERVAL_IN_MILLISECONDS);
    mLocationRequest.setFastestInterval(FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();
    builder.addLocationRequest(mLocationRequest);
    mLocationSettingsRequest = builder.build();
}

我会看一下 Google 的 LocationUpdatesForegroundService 示例项目:

看起来@Al-Amin 发布的解决方案来自同一个地方。尽管在没有署名的情况下发布其他人编写的代码一点也不酷。
