Angular 4 - Cannot read property '_android' of undefined about angularx-qrcode

[mpgo13]

Ran into the same issue with Angular 8 today.

Steps to reproduce:

1. Clone https://github.com/mpgo13/angular8-angularx-qrcode
2. Run ng build
3. Run cd dist/angular8 && python -m SimpleHTTPServer
4. Browse to http://localhost:8000

Expected Result:

• QRCode visible

Actual Result:

• Script error as commented above

Note: Not reproducable with angular's dev server (ng serve)

Hi @mpgo13, thanks for your sample Repo, I have a look into it.

A temporary workaround is to set the target in your tsconfig.json from es2015 to es5:

"target": "es5"

Hi @Cordobo, I've had this error and when searching the topic I ran into an interesting article:

Don't know if you've seen it but hope this helps you find a solution.

Could you please provide a stripped down sample repo?

Seems like qrcode.js gets loaded in strict mode. I opened an issue: angular/angular#30759

Hi @mpgo13 thanks for your minimal repo, I get this fixed as soon as possible.

I've updated my tsconfig.json, this is working for me:
"target": "es5"

I've used es2015 before.
