Android谷歌地图控制器内存泄漏

我在使用Android版谷歌地图时，内存严重泄漏。 特别是在使用mapController.animateTo时，我注意到了这一点。参见示例代码：从阿姆斯特丹开始，我通过增加latlng向南驶向意大利，但在3分钟内，堆化超过20Mb，#对象增加到68000或更多，应用程序崩溃。有人知道原因是什么或有解决办法吗

            super.onCreate(savedInstanceState);

            setContentView(R.layout.mapsleak);

            mapView = (MapView) findViewById(R.id.mapviewml);

            mapController = mapView.getController();
            mapController.setZoom(17);

            // We start in Amsterdam

                    // Italy here we come ;) (if it wasn't for the memoryleaking)
                    mLoc.setLatitude(mLoc.getLatitude() - 0.05);
                    mLoc.setLongitude(mLoc.getLongitude() + 0.05);
                    mGP = new GeoPoint((int)(mLoc.getLatitude() * 1E6), (int) (mLoc.getLongitude() * 1E6));
                    mapController.animateTo(mGP);

                 // System.gc();  Tried this already; does not help!
               }            
            };
            timer.schedule(moveOn , 1000, 2000);
        }
