[pepyakin]

@Salat-Cx65 can you format trace and strip logcat stuff like in this issue, please?
@pyricau maybe we should add trace formatting guidance into CONTRIBUTING.md?

Just in case, here is regexp to strip logcat buzz: ^.*D/LeakCanary\(\d*\):\W

[pyricau]

@pepyakin good idea but I'd add it to https://github.com/square/leakcanary#my-leak-is-caused-by-the-android-sdk-implementation . PR welcome!

[pyricau]

Thank you for your report, it looks like this might be a leak in the Android SDK.

Please read the following entry in our FAQ: Can a leak be caused by the Android SDK?.

We don't have enough time to do the investigative work on this type of issue, so I will close this issue for now. We'll happily take contributions to AndroidExcludedRefs.java, if the leak is demonstrated and the fix provided to AOSP.
