然而，在这个例子中，应用程序仍然在这样做后崩溃，我不确定为什么

只需将以下代码添加到应用程序标记中的清单文件：

android:largeHeap=“true”

我在android 5或更高版本上测试自己的应用程序时遇到了这个问题

从堆栈跟踪的外观来看，我怀疑您正在尝试加载可用于进度条的自定义位图，它绝对是巨大的。你能报告你与进度条关联的位图以及它有多大吗？button_download=508 x 121 imageView1=1000px×1500px假设深度为每像素24位，你的较大图像在内存中会超过4MB。android应用程序的可用最大堆大小因手机而异，介于16MB和256MB之间。看起来您在尝试加载此布局之前已接近应用程序的最大堆大小。你可以通过在你的清单中指定Android：LaGeHeAP=“true”来解决它，但是我强烈建议预缩放/优化图像拖拉的比特深度，作为限制你的应用程序消耗的内存量的第一步。我该如何进行预缩放？图像是从IMDB下来的-所以它们非常大。。。（我尝试添加Android：LaGeHeAP=“true”作为一个快速创可贴修复-但它仍然崩溃[感谢您的洞察力BTW]）我会搜索从URL解码的大小调整位图。在这里有相当多的项目解决了这个问题。

 @Override
        protected void onDestroy() {
        super.onDestroy();

        unbindDrawables(findViewById(R.id.ListView_layout));
        System.gc();
        }

        private void unbindDrawables(View view) {
            if (view.getBackground() != null) {
            view.getBackground().setCallback(null);
            }
            if (view instanceof ViewGroup) {
                for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
                unbindDrawables(((ViewGroup) view).getChildAt(i));
                }
            ((ViewGroup) view).removeAllViews();
            }
