Steps to reproduce the problem:
1. Install private android app
2. Launch webview activity (This activity uses google cloud print service)
3. Finish activity (when print is finished) and app screen goes black (not always, but 80% of times aprox.)

What is the expected behavior?
The webview activity finish ok and go back without black screen.

What went wrong?
When the webview activity finish (this wevbiew activity show google print service and finish when a document is printed), the next activity shows black screen at 80% of times. 

Did this work before? N/A 

Chrome version: 56.0.2924.87  Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 24.0 r0

I think that this is caused by webview app, because it calls to an https url and I can see at arc logcat issues related to this.
I have two https possible connections. 
One of them, is against a backend server (parse server)
The other one, is against google cloud print service. 

The one that may cause the issue is the google connection, because when I finish it (after print a document in my webview) the screen becomes black.

I think that the only times that the connection finish ok (webview activity finish ok and no black screen) is when I don't have use previously https connection to the server (at initial stages of the app, updates are not required, so backend service is not called always). But not always.

I'm losed with this issue, because I can not reproduce it at native android devices. I already have seen issues similar to this in other entries here, but any is solved.
