Question

我正在尝试在SKCoordinates中添加SKMapSurfaceview到SKPolyline地图的列表。执行SKSurfaceView.addPolyline( SKPolyline )

时

我从libc获得致命信号6 SIGABRT。

MapActivity.java

public class MapActivity extends BaseRouteActivity 
{

    ...

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_map);

        SKMapSurfaceView mapView = SKMapViewHolder mapHolder = (SKMapViewHolder)
                    findViewById(map_target);
        mapView = mapHolder.getMapSurfaceView();
        mapView.setMapSurfaceListener(this);

        List<SKCoordinate> coordinates = new ArrayList<SKCoordinate>();
        coordinates.add( new SKCoordinate( 52.390846319385254, 4.643051476057394 ) );
        coordinates.add( new SKCoordinate( 52.391088576419605, 4.643212408598288 ) );

        SKPolyline polyline = new SKPolyline();
        polyline.setNodes(coordinates);

        mapView.addPolyline(polyline);   
    }

    ...
}

Logcat错误

8009-8009/com.my.app A/libc﹕ Fatal signal 6 (SIGABRT) at 0x00001f49 (code=-6), thread 8009 (y.app)

我已经尝试将addPolyline包装在UIThread/AsyncTask中，因为我读到Android会杀死UI阻止功能中的所有网络流量，但无济于事。

我错过了什么？

编辑＃1 ：在LogCat中进行了一些挖掘后，我收到了这个错误：

JNI WARNING: GetFloatArrayElements received null array
in Lcom/skobbler/ngx/map/MapRenderer;.addobjectpolyline:([D[D[F[FIIII)I (GetFloatArrayElements)

这是一个SDK问题，将在下一个版本中修复。当未指定用于样式化SKPolyline对象的color和outlineColor属性时，会发生崩溃。为避免崩溃，您应指定折线的样式属性，如下面的代码所示：

List<SKCoordinate> coordinates = new ArrayList<SKCoordinate>(); 
coordinates.add( new SKCoordinate( 52.390846319385254, 4.643051476057394 ) ); 
coordinates.add( new SKCoordinate( 52.391088576419605, 4.643212408598288 ) ); 

SKPolyline polyline = new SKPolyline(); 
polyline.setNodes(coordinates); 

// set styling properties (crash will occur if color or outlineColor are not specified) 
polyline.setLineSize(9); 
polyline.setOutlineSize(4); 
polyline.setColor(new float[] {0, 0, 0, 1}); 
polyline.setOutlineColor(new float[] {0, 0, 0, 1}); 
polyline.setOutlineDottedPixelsSolid(6); 
polyline.setOutlineDottedPixelsSkip(0); 

mapView.addPolyline(polyline);

在SKMapSurfaceView上添加SKPolyline会导致SIGABRT
