App crashes on Android 9 (device and emulator)

We are developing an app using SalesforceMobileSDK-CordovaPlugin and recently found an issue with Android 9.
This is the error we are getting:
`I/chromium: [INFO:CONSOLE(0)] "Failed to load module script: The server responded with a non-JavaScript MIME type of "". Strict MIME type checking is enforced for module scripts per HTML spec.", source: file:///android_asset/www/runtime.js (0)

I/chromium: [INFO:CONSOLE(0)] "Failed to load module script: The server responded with a non-JavaScript MIME type of "". Strict MIME type checking is enforced for module scripts per HTML spec.", source: file:///android_asset/www/polyfills.js (0)

I/chromium: [INFO:CONSOLE(0)] "Failed to load module script: The server responded with a non-JavaScript MIME type of "". Strict MIME type checking is enforced for module scripts per HTML spec.", source: file:///android_asset/www/main.js (0)`

This project has cordova-plugin-ionic-webview plugin installed.

After some more debugging I think the issue is in SalesforceDroidGapActivity.java L472 where startUrl is hardcoded to file:///android_asset/www/. So even if cordova-plugin-ionic-webview plugin is installed and https:// is available, webview gets redirected to file:///android_asset/www/.

Then, App shows Blank screen with console error Failed to load module script: The server responded with a non-JavaScript MIME type of "". Strict MIME type checking is enforced for module scripts per HTML spec.", source: file:///android_asset/www/runtime.js

The code you pointed to is in loadLocalStartPage(). There is also a loadRemoteStartPage() method which loads the start page read in the bootconfig without prepending anything.
To have that method used, you need to set isLocal in your bootconfig file to false.

@wmathurin thank you for the prompt response. We'll check and let you know.

Thanks @wmathurin #609 (comment) fixed the issue.

Thanks for confirming the issue is fixed!

@wmathurin Solution in #609 (comment) breaks the auth flow when user is opening the app after logged in once. I believe this is because changing isLocal from true to false has other impacts.

Found working solution in PR #605.

@wmathurin any ideas why this PR was closed without merge. I think without changes in this PR this plugin doesnot work with cordova-android:10.x.x. Unless a fix for this already added in another PR.
