错误膨胀类和内存问题

Question

我有一个应用程序，它有 2 个主要布局并且确实使用了很多图片 (16)。该应用程序运行良好，但似乎在布局之间切换了几次后它崩溃了，我相信这是因为它的内存不足。除了缩小图片之外，我不确定如何解决此问题.. 有什么建议吗？

我之前遇到过类似的问题。我相信 问题是由于每次都重新创建位图 你开始活动。这是什么的sn-p 我确实是为了解决这个问题。

    Bitmap d;
    private void setImage(String path){
    if(d != null){
        d.recycle();
    }
    d = BitmapFactory.decodeFile(path);


    if(d != null){
        profilePicture.setImageDrawable(new BitmapDrawable(d));
        }       
    }
