android - android google maps v2内存不足异常

Question

当我在 map 上添加和删除标记时，一段时间后应用程序崩溃并显示内存不足异常消息。

logcat 响应是:

我的代码是:

loop 20 times:


    mapView.addMarker(new MarkerOptions()
                                        .position(new LatLng(latitude, longitude))
                                        .icon(BitmapDescriptorFactory
                                                .fromBitmap((bitmap)))
                                        .snippet(text + "             ")
                                        .title(mine_name));

对于每个新循环，我都会删除 map 上的标记并添加新标记。

我也对位图给予了足够的关注

bitmap.recycle and assign bitmap with null after used bitmap/

此 google api 存在一些问题。我们必须等待下一个版本......BitmapDescriptorFactory 有内存泄漏。
