Hi, I’m trying to deploy an app I’m building over and android mobile device which is a rather bit old. Its using the version 4.4.2 (Samsung S4 Mini) which based on the ionic official documentation should be supported.
When I manually install the generated debug build apk file on the device, it correctly installs it but when I try opening it, then the app stucks and doesn’t bootstrap (splash screen remains). The strange thing is that when I try installing it on another mobile phone using Android 7.X it works fine! (also checked on 8.X & 9.X)
UPDATE:
After reviewing a while, I ran my app from my VS code terminal to the mobile plugged in by USB cable and the same error occurred. This time I inspected the console log on Chrome’s Dev Tool to check for any errors, and indeed I got 2 errors.
The first one:
Uncaught TypeError: pre,template,textarea,script,style is not iterable
Reviewing this error I found two posts (link at the bottom) that suggested to uncomment some imports from the polyfills.ts from my project regarding older web versions. I did this, build and ran again and the error is gone but the app still doesn’t bootstrap. Now my console log looks like:
