(file:///android_asset/www/index.html)"" although the css and fonts file of MaterialIcons are in the assets folder (I've install it locally) there is no call to "https://fonts.googleapis.com/icon?family=Material+Icons" what can I do ? Can I fix it or know why the timeout suddenly .

Please check your device version ionic not properly work on android < 4.4.4 version you could try this above 4 version if you want to work with 4.* version you could install cordova-crosswalk plugin

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.

I add plugin:
cordova plugin add cordova-plugin-crosswalk-webview
then,
ionic cordova platform rm android
ionic cordova platform add android
ionic cordova build android (or Run)

Just need to also make sure that your mobile device is connected to the same wifi as your computer.

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.

1- Rename your index.html to “main.html”
2- Create a new “index.html” and put the following content into it:
<!doctype html>
<html>
<head>
<title>tittle</title>
<script>
window.location='./main.html';
</script>
<body>
</body>
</html>
3- Rebuild your app! No more errors!

As of now above solutions will work but the app will take time to load, instead of that you can simply add below in your MainActivity.java super.loadUrl("file:///android_asset/www/index.html");
In MainActivity.java you have to comment below code loadUrl(launchUrl);
public class MainActivity extends CordovaActivity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// enable Cordova apps to be started in the background
Bundle extras = getIntent().getExtras();
if (extras != null && extras.getBoolean("cdvStartInBackground", false)) {
moveTaskToBack(true);
}
// Set by <content src="index.html" /> in config.xml
//loadUrl(launchUrl);
super.loadUrl("file:///android_asset/www/index.html");
}
}
Add
<preference name="loadUrlTimeoutValue" value="60000" />To config.xml
