为什么堆大小不断增加？

问题描述

我有了很多的涟漪效果和动画的应用程序。

I have an application that has a lot of ripple effects and animations.

我试图来回多个屏幕，并且还垃圾邮件点击按钮。

I tried going back and forth multiple screens, and also spam clicking buttons.

我注意到，堆大小不断上升，尽管有些画面已经被关闭。

I noticed that the heap size continuously goes up even though some screens have already been closed.

当我检查了堆转储，以最高的保留堆是在 android.graphics.Bitmap 类，并指向所有的按钮我点击，有一个类连锁反应。

When I checked the heap dump, the class with the highest Retained heap was the android.graphics.Bitmap class and points to all of the buttons I clicked that has a Ripple Effect.

按钮上的涟漪效应只是简单的涟漪，它使用？ATTR / selectableItemBackgroundBorderless 作为背景。但它上升由0.3MB或0.5MB按钮中的每次点击与涟漪。

The Ripple Effects on the buttons are just simple ripples which uses ?attr/selectableItemBackgroundBorderless as the background. But it goes up by 0.3mb or 0.5mb on every click of the buttons with ripples.

推荐答案

可能是某种形式的MemoryLeak。这几乎是不可能告诉哪里出了问题，而不an​​alise的code。我推荐一些测试。

Could be a MemoryLeak of some kind. It's almost impossible to tell where is the problem without analise the code. I recommend some tests.

您可以尝试库。的lib可以看具体对象，缩小了泄漏搜索。

You could try the Leak Canary library. The lib can "watch" specifics objects and narrow the search for the leak.
