How to fix the connection to the server was unsuccessful. (file ///android_asset/www/index.html)

Question

I\'ve added material icons to ionic2 app , and since then I get error \"\"The connection to the server was unsuccessful. (file:///android_asset/www/index.html)\"\" although the

Answer 1

So I added manually the following tags in config.xml right at the beginning:

<allow-navigation href="*" />
<content src=“index.html” />
<content original-src=“index.html” />

it’s working.

Answer 2

Adding that ...value="70000" or "60000" line in config.xml isn't the best solution and it doesn't always work nor the creation of main.html file .

I was dealing with the same issue. These two solutions did not work for me.

SOLUTION

-Make sure you build with

ionic cordova build --prod and not ionic cordova build

-Check if one of your file or folder name doesn't contain Uppercase in it's context before building

like for example in "pages"

• templateView (instead of "templateview)

  • -templateview.ts
  • -templateview.html
  • -templateview.scss

and rename it (otherwise you will have errors)

When building finished, your app runs correctly without the "(file:///android_asset/www/index.html)" error.
