问题
I am trying to open html file that I have on my sdCard in Chrome or any other web browser (not html Viewer).
I have tried to enter path to file like this
file:///storage/extSdCard/page/page.html
I get this error:
ERR_ACCESS_DENIED
What could be wrong please?
EDIT: I have to mention that I am not developing a android app. I just want to view a html file, that is on my SD card in chrome mobile browser
EDIT2: It is not working from ext. sdcard and also from internal memory
Thank you.

This is simply happening because the chrome app doesn't have the permission to read the external storage.

Here is a list of chrome app permissions....

I had the same problem and the only way I found to solve the problem of reading the html file in Chrome in a device that isn't rooted is to copy or move the html file into the device's internal memory storage.
The alternative is to root the device and change the permissions to allow sdCard access in Chrome.

One way to work around was (on a device with a side loaded chrome)
adb shell pm grant com.chrome.canary android.permission.READ_EXTERNAL_STORAGE
"com.android.chrome" might be the name if you aren't using canary version of chrome.

I needed to do the same for my own website. I did not want to look up my website on the internet, because I would get charged by google adwords for clicking on it.
I copied the files of my website (index.html and all the folders) to the Internal Storage Download folder, in a folder mywebsite.com that I created.
In the Chrome browser, I typed the following:
file://com.estrongs.files/storage/emulated/0/Download/mywebsite.com/index.html
The website opened up perfectly with all the linked pages and images. I then bookmarked it as a favorite so I don't have to type the long url again. The directory structure I show is on my Samsung Android phone. It may be different on another android or iphone. The key is that the website files need to be on internal storage and not on the SD Card as Chrome does not have permission to access external storage.

Upload your html files into any app's internal file directory. I added my file to default browser app's directory.
And type the following url in your browser:
file:///storage/sdcard/Android/data/com.android.browser/files/yourfile.html
It should be successfully rendering the web page.
