HTML File as asset on Android 10 / 11

[wikki74]

Before Android 10 I downloaded some html, css files at first start of the app to a special folder (file:///mnt/sdcard....).
As this is not working any more I would like to include these files as assets, but I am wondering where I can find them ? What is the correct path to the assets folder uner Android 10 / 11 now?
Has the Device to be rooted the access the files?

Since Android 10 does not allow you to write in external storage so these files are stored in Application Specific Directory of Companion.

Thank you, but I can not see them using MyPhoneExplorer eg...

The folder assets does not exist in my ASD

[wikki74]

I used the filebyfile Method from Taifun https://puravidaapps.com/filebyfile.php.

So, the easiest way could also be to adapt the path to where the files will be downloadad?

Ok, so for API under 29 it is working.

For API 29 and above it is not working, i can get no connection to the file listview.html

This is the Path (of course ASD is replaced by the wright name)

/storage/emulated/0/Android/data/ASD/files/

Do I have to grant special READ Permission? On srart of the App WRITE Permission is already granted...

EDIT:
/storage/emulated/0/Android/data/ASD/files/

is making this:

Seems quite weird.
@Anke kindly have a look here.

@wikki74 See here and also read the entire thread:

Problem with July 30 2020 Version: nb184 no longer able to write and read files

No, it is written to the app-specific directory (ASD): Companion: /storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files compiled app (APK): /storage/emulated/0/Android/data/<packageName>/files Cause: The file component (for API level ≥ 29) adds the ASD path to the beginning of each path that you declare. If I save a text in the ASD [grafik] this path is returned (but doesn't exist and cannot be created): /storage/emulated/0/Android/data/edu.mit.appinventor.aico…

How to copy a sound from assets to ext. storage and play it from this path → API ≥ 29

How to copy a sound from the assets to the root directory of the external storage: /storage/emulated/0/sound.ogg (.mp3) and play it from this path on devices especially with API ≥ 29: [grafik] Note: This will stop working if AI2 targets API 30 (likely towards the end of 2021). Then you can only read / write to / from the ASD (app-specific directory).

This works also on Android 11 (API 30).

@vknow360

Since Android 10 does not allow you to write in external storage

Only when AI2 will target API 30 (targetSdkVersion = 30).

Google is giving developers until the end of 2021 to adapt their apps to...
