我的应用程序泄漏了我可绘制文件夹中没有的随机形状的位图 [英] My app leaks Bitmaps of random shapes that I don't have in my drawable folder

问题描述

我有一个奇怪的内存泄漏问题，我的应用程序不断泄漏Bitmap对象和其他与之相关的对象，例如VectorDrawables，AnimationDrawables

我通过Eclipse Memory Analyzer和Gimp能够恢复泄漏的Bitmap对象，并发现它们是星形，方形或圆形的随机形状.我的res/drawable文件夹中没有这些形状.

它们来自哪里，为什么泄漏那么多? 此泄漏发生在我的Samsung Galaxy S7 - Android 7.0和使用Android 7.0和6.0的模拟器上.但是，当我在运行Android 4.4.4

的Huawai上运行我的应用程序时，没有泄漏

而且我的stacktrace不断将这些行吐出来

解决方案

所以这个问题很难调试，花了我整整一周的时间.泄漏是从哪里冒出来的，CanaryLeak甚至无法检测到它.

我卸载了Android Studio，删除了User文件夹中AppData下PC中所有剩余的文件夹，并删除了C:/User和Program files甚至SDK文件夹下与Android或Android Studio有关的所有其他内容. /p>

使用CCleaner完全清除寄存器，然后再次下载Android Studio，从Git克隆我的项目，然后再次运行我的应用程序，就在这里！完全没有泄漏.

我敢肯定，这种疯狂的泄漏与您自己的应用无关，而与Android Studio有关或完全与其他有关

I have a strange memory leak problem where my app keeps leaking Bitmap objects and other objects related like VectorDrawables, AnimationDrawables

I have via Eclipse Memory Analyzer and Gimp been able to recover the leaked Bitmap objects and found out that they are random shapes of stars, and squars or circles. I dont have any of these shapes in my res/drawable folders.

Where do they come from and why are they leaking so much? This leak happend on my Samsung Galaxy S7 - Android 7.0 and on emulator with Android 7.0 and 6.0. But there are no leaks when I run my app on a Huawai running Android 4.4.4

Here is a link to my hprof. file if someone would take a closer look: https://www.dropbox.com/s/e1ry3ny5eb66xk8/out3%20-%20Kopi.hprof?dl=0

Also my stacktrace keeps spitting these lines out endlessly

解决方案

So this problem is so hard to debug and it took me a whole weeks work on it. This leak came out of no where and CanaryLeak can't even detect it.

I uninstalled Android Studio, deleted all remaning folders in the pc that is under AppData in your User folder and everything else related to Android or Android Studio under your C:/User and Program files and even the SDK folder.

Made a full clean up of the register with CCleaner and then downloaded Android Studio again, cloned my project from Git and then I ran my app again and here it was! NO LEAKS AT ALL.

I'm pretty sure that this crazy leak has nothing to do with your own app but something with Android Studio or something completely else
