Question

我有一个想要运行的动画，当我为它设置drawable时，会出现内存泄漏。我不知道它是否重要，但框架只在drawable文件夹中，而不是在特定的dpi文件夹中。甚至在我开始动画之前就会发生内存泄漏。当我设置动画的资源时会发生这种情况。谢谢！

电话：

logoAnimation.setBackgroundResource(R.drawable.logo_animation);

logo_animation.xml：

Answer 1

你正在加载大量的图像，大约60个。如果这些图像也比较大，这让我觉得内存泄漏是由OutOfMemoryException.

引起的

Here's a great article如何处理它。
简而言之，我们的想法是在将图像加载到内存之前缩小图像。

由img.setBackgroundResource引起的内存泄漏
