file:///android_asset no longer working

[Aurelien M]

Hi everyone

I am trying this trick of loading an HTML page from my assets into a WebViewer component but it fails. I've even written a file explorer type of interface to browse the directory structure (using TaifunFile.FileListASync) but there is no such path.

Reading on the Android documentation, it seems all assets are locked to the WebViewer unless the setAllowFileAccess variable is set to true. It was true by default prior to ICS but it's set to false by default from JellyBean onward.

See here for more details.

https://developer.android.com/reference/android/webkit/WebSettings.html#setAllowFileAccess(boolean)

Does anyone have a suggestion for load a local HTML file assuming the user will not have an Internet connection ever (except at install time)?

thanks a bunch!

the webviewer can load a html file from the assets or from the internet, but not from the sdcard

Thank you for the response, but my point was that it doesn't work from the assets. Loading anything from file:///android _asset/ fails on modern android devices...

this still works, at least on a Nexus 5X running Android 7

you might want to provide a screenshot of your relevant blocks

Yes, you also can upload html files as assets into App Inventor! There is only one special thing to consider: During development, you have to use the development path to the embedded html document:

file:///mnt/sdcard/AppInventor/assets/<NAME OF YOUR HTML FILE>.html

Before packaging the app, use the production path.

file:///android_asset/<NAME OF YOUR HTML FILE>.html

that's very odd. Here's my code that gets activated when a button is pushed. It tries to determine if a file:///android_asset/database.html file exists, if so, use it, otherwise use the development path.

Everytime I test on the emulator, it loads the development path as expected, however, when I run the code on my tablet (Lenovo Yoga Tab3 with Android 5.1.1), it still tries to use the development path (I have another Notifier element indicating what has been loaded)

I can't see any problem with my code...

thx

did you try that after building the app? 

usually I use a flag like this (taken from the table exmaple)

to make things easier, I also could provide a new method in an extension, which could return true or false in case an app is running in the companion app or not... in case you like to be the sponsor of that method, let me know
