当我在地图上添加和删除标记时，经过一段时间，应用程序会崩溃并显示内存不足异常消息。
logcat 响应如下:

我的代码如下:
loop 20 times:
mapView.addMarker(new MarkerOptions()
.position(new LatLng(latitude, longitude))
.icon(BitmapDescriptorFactory
.fromBitmap((bitmap)))
.snippet(text + " ")
.title(mine_name));
对于每一个新的循环，我会清除地图上的标记并添加新的标记。
我还特别注意了位图，使用完位图后，通过bitmap.recycle将其回收并将位图赋值为null。
