将图像加载到内存时出现内存不足错误

Question

我正在将多个图片加载到我的应用中。我必须加载它们以使用我的动画。

    ArrayList<AnimationsCls> animArr = new ArrayList<AnimationsCls>(); 

    for (int i = 0; i < 3; i++)
             animArr.add(new AnimationsCls());

    for (int j = 1; j <= numOfimages; j++) 
        animArr.get(0).f_anim.addFrame(Drawable.createFromPath(path+"/Sites/Site6/Zoom1/Zoom"+j+".jpg"), i);    

    for (int j = 1; j <= numOfimages; j++) 
        animArr.get(1).f_anim.addFrame(Drawable.createFromPath(path+"/Landscape/Sequence10/Landscape_WB_"+j+".jpg"), i);    

    for (int j = 1; j <= numOfimages; j++) 
        animArr.get(2).f_anim.addFrame(Drawable.createFromPath(path+"/Sites/Site2/Zoom1/Zoom"+j+".jpg"), i);    


    public class AnimationsCls
    {
    AnimationDrawable f_anim = new AnimationDrawable();
    //AnimationDrawable b_anim = new AnimationDrawable();
    boolean active;
    }

问题是，对于3个动画数组，内存是sufucuent，但如果我添加更多，我的内存不足。我已经通过Photoshop编辑图像到最小尺寸，每个图像权重输出90kb。已经为清单添加了大堆。如何在不释放图像的情况下缩小内存中图像的大小？

我在DDMS中的记忆：
