Even if this question is quiet old. I think a small tutorial with images might be helpful. So first you need to install the <a href="http://www.eclipse.org/mat/" rel="nofollow noreferrer">MAT plugin</a>. After a restart click on Dump HPROF file:

<img src="https://i.stack.imgur.com/2Fe0C.png" alt="Device controls">

After some time (about 30 seconds) you'll get a dialog where you can click on finish. Than you get this view:

<img src="https://i.stack.imgur.com/riXtI.png" alt="Dump result">

There you left click on the biggest part and filter for with outgoing references. Then you get this view here:

Here you can see that I missed to delete items in my ContentManager where several items were stored in my pending <code>HashMap</code>.

Use LeakCanary - a memory leak detection library for Android and Java.
LeakCanary will automatically show a notification when an activity memory leak is detected in your debug build. Installing this library is very simple.

I can't comment on the previous post, but it's important to realise that you absolutely should worry about memory management, especially on the resource-confined environment that is the Android mobile platform. For more on that, check here:

我是这个Android平台的新手。在一个应用程序中，存在内存泄漏。但我找不到内存泄漏发生在哪个活动或类中。我正在使用MAT来获取内存泄漏是否存在的信息。但是找不到正在泄漏的活动。请告诉我如何找到泄漏的活动。谢谢。
