内存溢出异常 - 谷歌地图的GroundOverlay [英] Out of Memory Exception - Google Map GroundOverLay

问题描述

我想绘制谷歌地图上的图片。我使用了最新版本的谷歌的播放服务，并查了很多关于这个问题，并不能找到答案。

I'm trying to draw a picture on the google map. I'm using the latest version of google play services and checked a lot for this issue and couldn't find an answer.

下面是一些code：

    BitmapDescriptor image = BitmapDescriptorFactory.fromResource(R.drawable.drawing_bg);
    LatLngBounds drawingBounds = new LatLngBounds(
                                   new LatLng(29.93530, 30.88324), 
                                   new LatLng(29.93609, 30.88329))
                                .including(new LatLng(29.93580, 30.88286))
                                .including(new LatLng(29.93563, 30.88374))
                                .including( new LatLng(29.93593, 30.88347))
                                .including(new LatLng(29.93561, 30.88298))
                                .including(new LatLng(29.93591, 30.88344))
                                .including(new LatLng(29.93563, 30.88301));
    GroundOverlay groundOverlay = mMap.addGroundOverlay(new GroundOverlayOptions()
     .image(image)
     .zIndex(2)

     .positionFromBounds(drawingBounds)
     .transparency((float) 0.0));

    final Marker currentLocationMarker = mMap.addMarker(new MarkerOptions().position(new LatLng(29.93530, 30.88324)).draggable(true));
    mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(29.935431502437588,30.88327579200268), 20));

从LogCat中：

推荐答案

您不应该使用太大的图像。你logcat的建议你尝试分配67 MB，这是太多了大部分的设备。

You should not be using images that are too large. You logcat suggests you try to allocate 67 MB, which is way too much for most of the devices.

编辑：

也许尝试使用 TileOverlay 而不是的GroundOverlay 如果你想显示在大面积的图像（城市，国家），并没有放大时像素化。

Maybe try using TileOverlay instead of GroundOverlay if you want to show images on a large area (city, country) and not have it pixelated when zoomed.
