Android Widget Canvas - java.lang.IllegalArgumentException

我的應用程序中有一個Widget，它具有用於顯示畫布的ImageView。Android Widget Canvas - java.lang.IllegalArgumentException

如果我看着我的用戶Crashs我看到這個錯誤非常頻繁（但始終只是少數設備）：

java.lang.RuntimeException: Unable to start receiver my.package.name.WidgetProvider: java.lang.IllegalArgumentException: RemoteViews for widget update exceeds maximum bitmap memory usage (used: 5715000, max: 5529600 /*these arent always the same :)*/) The total memory cannot exceed that required to fill the device's screen once.

我的畫布具有動態的大小，當用戶調整其大小自動調整大小，和已指定的高寬比，則創建這樣的：

Resources r = context.getResources(); 
    SharedPreferences widgets = context.getSharedPreferences("widgets", 0); 

      //these are stored in onAppWidgetOptionsChanged when user resizes his widget 
    int w = widgets.getInt(widgetId + "_width", 130); 
    int h = widgets.getInt(widgetId + "_height", 160); 

    w = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, w, 
      r.getDisplayMetrics()); 
    h = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, h, 
      r.getDisplayMetrics()); 

    float scaleX = (float) w/(float) 13; 
    float scaleY = (float) h/(float) 16; 

    float scale = 1.5f * (scaleX < scaleY ? scaleX : scaleY);//i multiplied it with 1.5 because the canvas was very unsharp 

    w = (int) (13 * scale); 
    h = (int) (16 * scale); 

    RemoteViews remoteViews = new RemoteViews(context.getPackageName(), 
      R.layout.widget); 


    Bitmap bmp = Bitmap.createBitmap(w, h, Bitmap.Config.ARGB_4444); 
    Canvas canvas = new Canvas(bmp); 


[...] 

    remoteViews.setImageViewBitmap(R.id.widget, bmp); 

    appWidgetManager.updateAppWidget(widgetId, remoteViews);

我估計是因爲畫布是1.5倍比插件較大，但否則它是非常不清晰的。

我該怎麼辦？

在此先感謝。
