r/AndroidQuestions on Reddit: Open a local HTML file on a phone?
September 9, 2024 -

I considered it a no-brainer. I was wrong.

I wanted to take along some files to read when I'm out of network reach or in flight mode. The files happen to be quite plain HTML files, no script, just a CSS file defining the simple layout, and that's it. So I copied the HTML and the CSS files onto my phone and tried to open them.

First attempt was from a file manager. It told me that it no idea what to do with an HTML file. I then tried to look for an "open file" entry in Chrome. Nope. Same in Firefox. Then I tried to force-open the files by using a file:///path/to/file style URL - and it actually submitted the whole string to Google as a search string, as if Chrome (and Firefox) had been lobotomized of the file: protocol.

Now I'm at a loss - is there no way to open a simple HTML file on an Android 13 phone?

HTML Viewer is not a virus and you shouldn't be alarmed.

Actually it is a core application in most android versions (It's also present on my device running android 4)

HTML viewer (as the name suggests) basically lets you read HTML files stored on your device and it occasionally handles some .txt or related extensions of files present on your device and normally appears alongside other .txt handling applications.

Under normal circumstances you should be able to remove defaults of the HTML Viewer as an individual app:

  • Go to Settings โ†’ Apps โ†’ Tap 3 dot menu โ†’ Show system.
  • Select HTML Viewer โ†’ Open by default โ†’ Clear defaults:

You also can reset default applications by following this procedure:

  • Go to Settings โ†’ Apps โ†’ Tap 3 dot menu โ†’ Reset app preferences then click Reset Apps to confirm:

Alternatively as beeshyams suggested: using an app like Better Open With provides flexibility to choose the prefered app even if its one.

Update

Lib Caris is right by claiming that "even by clearing defaults/resetting preferences" HTML Viewer still opens .txt despite these interventions, and I agree with him.

Don't know if I can call it a bug, I reproduced this issue again and even if defaults are cleared the changes are not confirmed in android (Android 6).

Nevertheless I have two workarounds to bypass this "bug":

1. Temporarily disabling HTML Viewer

  • Go to Settings โ†’ Apps โ†’ Tap 3 dot menu โ†’ Show system.
  • Select HTML Viewer โ†’ Disable:

  • After disabling HTML Viewer, navigate to your device storage and look for any .txt file and open it.
  • You will notice it will open with any available text viewer (not HTML Viewer)
  • Next follow the above procedure and re enable HTML Viewer.
  • Then try opening the .txt file again, this time around the defaults are cleared automatically and you have a chance to choose your preferred text viewer:

2. Choose open as with file manager

  • Alternatively, directly navigate to any .txt file on your device storage with a suitable file manager e.g ES explorer .
  • Long press the .txt file and choose "Open As" โ†’ Clear defaults

Final Update

Due to problems in language barrier, it was a challenge to provide a conscise solution, nevertheless I will express my sincere gratitude to Lib Car, in his quest to address the problem and identifying pointer that ultimately solved this issue:

I did not find it since the beginning because it's name is NOT " HTMLViewer ". The NAME is " Visionneuse HTML " :
