Out of Memory Exception - Google Map GroundOverLay

问题

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.

Here's some 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));

I would really appreciate any help

回答1:

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.

Edit:

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.

回答2:

These 67Mb you are seeing seem to be from a confirmed bug in google maps, see here for more info: https://code.google.com/p/gmaps-api-issues/issues/detail?id=7325

It was fixed back in February (2015 for the record). It should be solved if you use the latest version of google maps.
