Android：将图像加载到位图对象时出现奇怪的内存不足问题

我正在创建一个游戏。它工作得很好，但有时它会抛出这样的消息：Out of memory on a 1024016-byte allocation！我不明白为什么android确实不能分配1MB的内存？我正在使用BitmapFactory.decodeResource(res, id)功能。如果位图变得无用，我会立即回收它！我什至减小了位图的大小！如果有人知道如何解决此问题，我将不胜感激！LogCat 下面：

public static Bitmap getBmpFromRes(Resources res, int id){  
    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inSampleSize = 1; // sample size value depends upon your image  so you have to              calculate it on run time.
    options.inPurgeable = true; //IMP
   return  BitmapFactory.decodeResource(res, id,options); }
