Taifunfile extension not working on Android 11 version

[auranet (Auceli Neto)]

Taifunfile extension works perfectly on Android version 9, but when I tried to install the app on Android version 11 it gave problems. The extension cannot read the device’s internal or external memory. Has anyone solved the problem?

How to request and grant MANAGE_EXTERNAL_STORAGE permission

In this guide I show you, how to request and grant → MANAGE_EXTERNAL_STORAGE on devices with Android 11+. Be aware that this permission is usually not granted by Google. However, let’s assume the app is only intended for private use or for special users or for other app stores . This permission must be declared in the Manifest ( since it is not declared the Companion app you can’t test this with Companion): <uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"/> Here is a…

[Android ≤ 10] How do I read from a file in Internal Storage instead of SD Card with file component?

It should read: Android ≤ 10, because Kodular has decided to continue to declare android: requestLegacyExternalStorage = "true" in the Manifest (therefore it still works under Android 10). See also here:

Image Optimizer extension issue in Android 11

You can no longer save in the root dir of the external storage on Android 11+. Save in one of the Shared folders or in the ASD: [grafik] or in the shared folder /Download: [grafik]

FileTools : Some tools to work with files

You can no longer write / save in any folder of the external storage on Android 11. You have to copy / move it (a non-media file) to one of the Shared folders (/Download or /Documents). See also here:

Image File storage path Reading file problem

@Asif_Hussain Use this extension and check what’s the correct file path maybe this can help you

Is WRITE permission needed to edit a file in the ASD?

@AppHelper_Studio You cannot pick any non-media files from the external storage (even not from one of the Shared folders, like /Download or /Documents, at least not on Android 11+). You need SAF for this. See here:

SAF: App Inventor implementation of Storage Access Framework

Tried but it doesn’t work, it doesn’t give permissions to read mp3 files. Something in the permissions is still missing to allow reading the files.

[Taifun]

starting from SDK30 you are not allowed to access arbirary directories anymore, see also the overview

Some basics on Android storage system

I have added another detail to my overview (top right, see pink box) and thus completed the overview. (I hope. ) [grafik]

I saw all the comments but couldn’t find an answer to the problem. Can we no longer read files with Kodular?

[Taifun]

@auranet

Can we no longer read files with Kodular?

as already said earlier you are not allowed to read from arbitrary directories anymore
you can read from shared directories like /Music together with READ_EXTERNAL_STORAGE permission, see again the overview
do you plan to publish your app on Google Play?

[auranet (Auceli Neto)]

I plan to publish it on Google Play. But as I couldn’t make it work in version 11, the publication is not viable.

[Taifun]

taking a look again at your screenshot…

to ask for permission takes its time… therefore it does NOT make sense to ask if the permission is granted directly below the AskForPermission block…

as test, move all blocks below the AskForPermission block into a button click event and test again

btw. if you take a look again at the overview, you will see, that you can read media files also from non private external storage with READ_EXTERNAL_STORAGE permission…

Taifunfile extension works perfectly on Android version 9, but when I tried to install the app on Android version 11 it gave problems.

This doesn’t work on any Android version and any device with a removable SDcard:

[auranet (Auceli Neto)]

@bodymindpower

Isso não funciona em nenhuma versão do Android e em qualquer dispositivo com um SDcard removível

I don’t understand what you mean by “This doesn’t work on any version of Android and on any device with a removable SDcard” because I’ve been using it for a long time. It finds my more than 2000 mp3 files on the sdcard and local memory on my device with Android 9, already in version 11 it doesn’t work and if I put subdirectories as True it gives an unexpected error.

@auranet

It finds my more than 2000 mp3 files on the sdcard and local memory on my device with Android 9

No, not from /storage/emulated/0/
(tested on two of my Android 9 devices):

[auranet (Auceli Neto)]

Did you manage to locate some mp3 file right? I can’t tell which of the drives is being located such files on my device. The question is, why on Android 11 I can’t do the same scan and return the found mp3 files?

[bodymindpower (Anke)]

Try this: listMp3sFromSDcards.apk (5.3 MB)

[auranet (Auceli Neto)]

That’s exactly what I need, how do I get it? Could you please pass me the blocks or the aia? I’ve tried everything and I can’t solve the problem.

[auranet (Auceli Neto)]

listMp3sFromSDcards.apk (5.3 MB)

Does anyone know which extension or component can be used to play a list with folders for mp3 music selection like in this application Anke sent?

[Taifun]

please be patient until you get the answer from @bodymindpower
you should be able to do it with any file extension…

This is all you need:

[bodymindpower (Anke)]

Look carefully at my blocks (left) and yours (right) and then you will find your mistake.
(A bit of guesswork is required, but it’s very obvious!)

[auranet (Auceli Neto)]

I made the correction but it still doesn’t work, it doesn’t find the mp3 files and it closes automatically. What can go wrong? I’m running on Companion.

[bodymindpower (Anke)]

@auranet

What can go wrong?

Post the aia.
