Able to reproduce the issue in Android. Observed the application is not responding.

Steps Followed:
1. Launched Chrome Browser.
2. Navigated https://app.tianyancha.com/channel?channelCode=WAP01
3. Observed the application is not responding.

OS
Android 7.0.0

This seems to be a Non-Regression issue as same behavior is seen since M58. Untriaged for further input's on this issue.

Thanks!!

can any people fix it？thanks a lot.

yfriedman@ can you triage to whomever is looking at ANRs?  Thanks!

I suspect the website is chugging away at heavy javascript and we're somehow blocking on it.
sandeepkumars: can you include a bugreport so I can look at the ANR data? It doesn't show up in logcat

You can see near the end of the video that the progress bar jumping around making it seem like the page is constantly being reloaded. I can repro this on a Nexus 6p as well. Log is continuously printing:

I'm assuming this is causing an ANR on some devices just because the amount of work being done. My 6P is gets janky but doesn't actually ANR.

Hopefully this was fixed by some of smaier's AsyncTask changes. Please re-open if it happens on new builds.
