Android地理围栏是否能够重启？

系统是持久存在还是我必须在重启后再次添加它们？我在https://developer.android.com/training/location/geofencing.html的文档中没有找到任何相关信息.

如何在Geofence android中添加后台服务

我正在尝试使用后台服务为监视器创建地理围栏.地理围栏创建成功并在应用程序活动打开时工作,但在关闭应用程序地理围栏时不起作用.我现在应该怎么做.我的代码是:

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback,
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener,
    LocationListener {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

    ref = FirebaseDatabase.getInstance().getReference("MyLocation");
    geoFire = new GeoFire(ref);
    mVerticalSeekBar = (VerticalSeekBar)findViewById(R.id.verticalSeekBar);

    setUpdateLocation();

如何在JavaScript中围绕折线绘制多边形？

我想在折线周围绘制一个多边形.在我的情况下,折线是Google地图方向,我需要在Google地图画布中围绕它展示多边形.

第一:

对于抵消,我使用JavaScript Clipper Library.我有以下折线(路线):我使用Clipper在下面创建一个偏移多边形:

我有一个有效的JS Bin示例.

代码是:

<html>
  <head>
    <title>Javascript Clipper Library / Offset polyline</title>
    <script src="clipper.js"></script>
    <script>
    function draw() {
      var polygons = [[{"X":72,"Y":59.45},{"X":136,"Y":66},{"X":170,"Y":99},{"X":171,"Y":114},{"X":183,"Y":125},{"X":218,"Y":144},{"X":218,"Y":165},{"X":226,"Y":193},{"X":254,"Y":195},{"X":283,"Y":195},{"X":292,"Y":202},{"X":325,"Y":213},{"X":341,"Y":234},{"X":397,"Y":245},{"X":417,"Y":248}]]; 
      var scale = 100;
      reverse_copy(polygons);
      polygons = scaleup(polygons, scale);
      var cpr = new ClipperLib.Clipper();
      var delta = 25;
      var joinType = ClipperLib.JoinType.jtRound;
      var miterLimit = 2;
      var AutoFix = true;
      var svg, offsetted_polygon,
      cont = document.getElementById('svgcontainer');
      offsetted_polygon = cpr.OffsetPolygons(polygons, delta * scale, joinType, miterLimit, AutoFix);
      //console.log(JSON.stringify(offsetted_polygon));

      // Draw red offset polygon
      svg …

Android地理围栏API BroadcastReceiver未触发

我正在尝试使用Google Play服务中的geofencing api,但我无法设法让我的广播接收器触发其onReceive()方法.

看起来我尊重使其工作所需的一切,但我没有过渡事件.

我在我的依赖项中包含了google play服务
我请求ACCESS_FINE_LOCATION许可
我BroadcastReceiver在我的Manifest中注册了我的导出值设置为"true"(有人说它是必需的)
我想补充的地方,我(我与谷歌地图验证它放在我的手机)的确切位置一个大地理围栏与两个过渡类型,并没有过期
我在地理围栏的中间尝试了一个精确的模拟位置,并在10秒后尝试了另一个地理围栏(我确保ACCESS_MOCK_LOCATION存在延迟)
我确认我的手机位置已打开,其模式设置为高精度
我验证了互联网连接
添加地理围栏后,我尝试使用和不连接LocationClient

但是,我仍然获得了成功的onAddGeofencesResult()回调,但没有onReceive()回调.我尝试使用Nexus 5和Nexus 7,两者都无法触发地理围栏过渡.

我还尝试了https://developer.android.com/training/location/geofencing.html上的示例,但其行为完全相同.

这是我的BroadcastReceiver班级:

public class GeofencesReceiver extends BroadcastReceiver implements ConnectionCallbacks, OnConnectionFailedListener, OnAddGeofencesResultListener {
    private final static String TAG = "GeofencesReceiver";

    private Context context = null;
    private LocationClient locationClient = null;

    /**
     * An empty constructor is needed by the manifest.
     */
    @SuppressWarnings("unused")
    public GeofencesReceiver(){}

    public GeofencesReceiver(Context context){
        this.context = …

Android Geofence活动未收到意图

一切都正确构建并在模拟器中运行,但我似乎无法让我的IntentService记录任何东西.我确信有一些我缺少或忽视的基本内容,但我对Android/Java很新,并且此时已经没有想法了.
