ViewGroup.ViewLocationHolder leak in Android P

[helloseyedjafari]

I'm testing my app with the new leak canary and on different devices (as well as virtual devices).
everything looks fine on all devices except one device which is the only one running Android 8.
the analyzing process looks fine but whenever it finishes it shows a few leaks (which other devices won't show!).

every time I check the trace I end up either with ReportFragment or InputMethodManager.

is anything actually leaking? is this an excluded leak?

thanks in advance

Can you share the full text leaktrace (click ... in the top right)?

[helloseyedjafari]

sure thing:

Leak Trace.txt

here is a heap dump file too. but it's not for this particular leak, for a similar one.just in case.

heap dump

I'm seeing a similar thing too from ReportFragment. Although in our case I am more inclined to believe we are doing something stupid with our app 😃. Here's our leak trace for comparison My.Leak.Trace.txt.

I'm happy to raise this in a different issue if it's better that way.

For me, the AccessibilityManager is holding onto it: leak.txt

Similar issue on Oreo(S8+) and Android Pie(Pixel2XL).
I have an app with TabLayout navigating via ViewPager having Fragments. Simply opening the app and swiping to the 3 Tabs and then closing causes a leak MainActivity and ReportFragment Leaks. I've googled but have no idea how to resolve them as yet.

Uploading Mainactivityleak.txt…

Note that your work Guys, is really highly appreciated. Thanks.

hi I got the leak on Pixel Emulator running Android 8.1 too, here is my leak trace

[ZacSweers]

I've filed a bug with a repro case here for anyone that wants to follow: https://issuetracker.google.com/issues/112792715

[PaulWoitaschek]

Am I the only one or did they hide the issue from the public? oO

[JakeWharton]

Yes. A comment was left before doing so to notify watchers. It is also already fixed.

Thanks, found the mail. If someone is wondering:

pw...@google.com added comment #9:
This is in the framework, not in the support library. Thanks for reporting it. I'm going to move it to the correct internal component, which will cut off public access to it (sorry).

[svenjacobs]

So this is an Android issue starting with Oreo? It also occurs on a Pixel with Android Pie. Will this be fixed in a monthly security update or do we have to wait for Android 9.1 or even 10?

[ZacSweers]

You'll have to wait till it's fixed in AOSP. It's such a nuisance that I've actually just disabled leakcanary on P all together :/
