capacitor: bug: (critical) Blank screen startup (only on device); error of Capacitor libraries

Bug Report

Capacitor Version

2.4.6 (for all packages)

This happens when opening the app in a device, and debugging it with Chrome Remote Devices. Nothing can be seen, just a blank screen (while the “ionic serve” app in desktop works perfectly normal):

Platform(s)

Only tested in Android so far. Doesn’t happen in the normal web app when developing with “ionic serve”.

Current Behavior

The app works perfectly as intended when served as a web app, as aforementioned. But it won’t start or do anything in an Android device: it just throws that stacktrace that I mentioned above.

Expected Behavior

App should start as normal in the device.

Other Technical Details

npm --version output: 6.14.11

node --version output: 15.7.0

This is my dependency list, do you see anything that could be causing this error?

I know this issue is marked as closed, but I’m currently having the exact same problem with ionic 6.18.1. When I create a blank project, package.json and package-lock.json indicate that it uses angular (core, router, common, etc) ~13.0.0.

When I use the my-first-app template instead, it works perfectly inside the device. The only difference regarding angular I found was that said template used angular 12.0.1.

Angular expects users to provide their own polyfils for APIs then need. To polyfill .bind, install this

https://github.com/leahciMic/polyfill-function-prototype-bind

npm install --save polyfill-function-prototype-bind

Then import it in your polyfills.ts file before zone.js

import 'polyfill-function-prototype-bind'


import './zone-flags';
import 'zone.js/dist/zone';

Also, be sure to do either a prod build or enable aot during dev builds by add "aot": true to your angular.json

      "architect": {
        "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
+           "aot": true,
            "outputPath": "www",
