內存不足例外 - 谷歌地圖GroundOverLay

Question

我試圖在谷歌地圖上畫一張圖片。我正在使用最新版本的谷歌播放服務，並檢查了很多這個問題，並找不到答案。

下面是一些代碼：

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)); 

從logcat的：

我真的很感激

Answer 1

你不應該使用太大的圖像進行任何幫助。你logcat建議你嘗試分配67 MB，這對於大多數設備來說太過分了。

編輯：

也許嘗試使用TileOverlay代替GroundOverlay如果你想顯示（城市，國家）在大面積的圖像，而不是把它放大像素化時。

Answer 2

這些67MB你看到似乎是從谷歌地圖確認的錯誤，在這裏看到更多的信息：https://code.google.com/p/gmaps-api-issues/issues/detail?id=7325

它被固定在2月份（2015年備案）。如果您使用最新版本的Google地圖，應該解決它。
