可能重复： Android: Strange out of memory issue while loading an image to a Bitmap object

我在创造一个游戏。它的工作原理非常完美，但有时它会像这样抛出这样的信息：Out of memory on a 1024016-byte allocation！我不明白为什么android不能分配1MB的内存呢？我在使用BitmapFactory.decodeResource(res, id)函数。如果一个位图变得无用，我立即回收它！我甚至缩小了位图的大小！如果有人知道如何解决这个问题，我会感激的！LogCat如下：

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); }
