Android应用程序崩溃时，它创建一个折线

Question

每当它试图创建一条线时就会崩溃。我想用PathOverlay，但已经不推荐了。我想画一条线。

public void drawLine(){
    List<GeoPoint> track = new ArrayList<>();
    track.add(new GeoPoint(14.4889,121.0325));
    track.add(new GeoPoint(14.4906,121.0353));

    Polyline roadOverlay = new Polyline(map.getContext());
    roadOverlay.setPoints(track);
    map.getOverlays().add(roadOverlay);
    map.invalidate();
}

我想这会有帮助吗？我的osmdroid磁贴位于手机存储器中：

尝试删除地图。使无效。。我猜在onCreate中不需要它，因为在onCreate存在后将生成视图。
