内存不足异常-谷歌地图地面覆盖

Question

我想在谷歌地图上画一幅画。我使用的是最新版本的google play服务，并检查了很多这个问题，但没有找到答案。

下面是一些代码:

    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:

我非常感谢你的帮助

Answer 1

您不应该使用太大的图像。您的logcat建议您尝试分配67 MB，这对大多数设备来说都太大了。

编辑:

如果你想在一个大的区域(城市，国家)上显示图像，而不是在放大时像素化，可以尝试使用TileOverlay而不是GroundOverlay。

Answer 2

你看到的这67Mb似乎是来自谷歌地图的一个确认的bug，更多信息请参阅这里:https://code.google.com/p/gmaps-api-issues/issues/detail?id=7325

早在2月份(记录为2015年)就修复了。如果你使用最新版本的谷歌地图，这个问题应该可以解决。
