App failed to run on Android Oreo

Ionic Framework ionic-v3
1

Hi all.
My apps on Google Play failed to run after I upgraded my phone Android Oreo with the message - Application Error. The connection to the server was unsuccessful. (file:///android_asset/www/index.html) which appear after the splashscreen.
The apps were running fine before the upgrade.
Then, I tried creating a blank app with both android@6.4.0 and android@7.0.0. Both versions on device gave me the same error.

ionic info

@ionic/cli-utils  : 1.19.0

local packages:

@ionic/app-scripts : 3.1.6

Anybody face the same issue?

Turns out to be phone-related (Huawei Mate 8).
After enabled Settings - Developer options - Enable multiprocess Webview, all the apps are running without error.
