ionic android white screen after showing the splash screen

Question

I have built an apk file using ionic cordova build android. And I have opened that app using Genymotion emulator. When I opened the app, it starts and displays the splash screen. After that a white screen appears forever (I can close the app. But when I start that again, same thing happens).

I have captured the error in the android studio console.

Here they are,

And then I have opened the main.js file in that apk. In line 40, I have found this code.

Then I browsed the scanner.ts in pages (./pages/scanner/scanner.ts) folder. I did not find anything wrong. It works when I run that using cordova run browser.

scanner.ts

Here are some more information on my setup:

Answer 1

Changing the target value in the tsconfig.json from es6 to es5 has worked.
Eg. "target": "es6" >>> "target": "es5"

Note: This problem will not automatically happen to the project unless you declare that explicitly.
