# Bug Report
## Problem
Using Android 12, I can't load javascript or css files within my app. My
app has been in in the Google and Apple stores for 4 years and is working fine.
This same code and configuration works fine for iOS.
### What is expected to happen?
Tried to load jQuery (as an example) from index.html and when that failed, I
tried to load it from index.js after the deviceready event had fired. Both
experiments failed.
### What does actually happen?
Both fail with a `Failed to load resource: net::ERR_CONNECTION_REFUSED`
## Information
To simplify reproduction, I built the "get ready" example.
### Command or Code
% cordova create test2023b
% cd test2023b
% cordova platform add android
Added to config.xml: `<preference name="android-buildToolsVersion"
value="34.0.0" />`
% cordova run android
The app starts in the simulator, but the console.log reports:
`cordova_plugins.js:1 Failed to load resource:
net::ERR_CONNECTION_REFUSED`
`index.js:27 Running cordova-android@12.0.0`
`favicon.ico:1 Failed to load resource:
net::ERR_CONNECTION_REFUSED`
I added "'unsafe-inline' 'unsafe-eval'" to the "Get Started"
Content-Security-Policy in index.html, but there was no change.
I have a CSP that is currently working in my released app with 6 month old
libraries.
Using this "released" CSP had no effect:
<meta http-equiv="Content-Security-Policy" content="
default-src * wevotetwitterscheme: data: content: gap:
https://ssl.gstatic.com;
img-src * https://*.twimg.com https://*.twitter.com/ data: https:
blob: android-webview-video-poster: ;
style-src * https://*.twimg.com 'unsafe-inline';
script-src 'self' http://* 'unsafe-inline' 'unsafe-eval';
frame-src http://*.facebook.com https://*.facebook.com
https://*.facebook.com https://*.twitter.com https://twitter.com
https://*.vimeo.com https://*.googlevideo.com https://*.youtube.com gap:
'unsafe-inline';
child-src gap://* ;
font-src *;
media-src *;
" />
Then I tried an experiment to load jQuery from index.html by adding
`<script
src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js";></script>`
before the `</body>`
And the results from the console log were:
` cordova_plugins.js:1 Failed to load resource:
net::ERR_CONNECTION_REFUSED`
` cordova.js:1237 deviceready has not fired after 5 seconds.`
` cordova.js:1230 Channel not fired: onDOMContentLoaded`
` jquery.min.js:1 Failed to load resource:
net::ERR_NAME_NOT_RESOLVED`
` index.js:27 Running cordova-android@12.0.0`
` favicon.ico:1 GET https://localhost/favicon.ico
net::ERR_CONNECTION_REFUSED`
I also tried adding
`<access origin="https://ajax.googleapis.com/*"; />`
`<access origin="https://localhost/*"; />`
with no effect.
### Environment, Platform, Device
Mac OS 13.4.1 (c)
Simulator for a Pixel 6 Pro
### Version information
12.0.0 (cordova-lib@12.0.1)
android 12.0.0

"run" with no Android Studio.
