File component problem

[Yeiberey_Reyes (User)]

Hello good dear programmers, I would like you to help me with the failure of the file component, thank you very much in advance!

I am trying to read a JSON file with the Read From method but this gives a negative answer, I thought that the file was not there or that I had misspelled the path so I looked in this community for an extension that would check the existence of a TaifunFile file and use the method Exists instead this if it gives a positive answer, check that there is a problem with the component. someone knows of any solution, extension that can help.

Thank you so much!

No, there is no solution (without requesting MANAGE_EXTERNAL_STORAGE permission, which will not be granted by Google).

The File component basically redirects all paths to the ASD on Android 10+ devices. On Android 11+, any folder can no longer be created in the external storage and the access to manually created dirs (outside of Shared folders) is denied.

Some basics on Android storage system

From an Android point of view there are an → Internal Storage and an → External Storage. 1. Internal Storage The Internal Storage can only be accessed with a rooted device. 1.1 The app package is saved in /data/data/<packageName>/ 1.2. The Private directory is /data/user/0/<packageName>/files/ This private directory can be used with the File component to save / read text (setting the path without a slash). It can only be accessed by your app and is automatically removed when the app is un…

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…

@Taifun

Good question.

@Taifun

did you create that directory?

Since targetSdkVersion=30 there is no way to create such a dir on Android 11+.
So the question should be: Did you create that dir manually or before targetSdkVersion=30?

internal storage

there is a property of the Legacy Mode component, set to true and that solved the problem.

previously it worked without disabling this function, why does it now work this way?

[Yeiberey_Reyes (User)]

@bodymindpower

Dado que targetSdkVersion=30 no hay forma de crear un directorio de este tipo en Android 11+.
Entonces, la pregunta debería ser: ¿Creó ese directorio manualmente o antes targetSdkVersion=30 ?

I have created this directory with a download extension, the developer deepHost. Still works

Thank you very much for answering

It works on Android 10, because Kodular has decided to continue to declare android:requestLegacyExternalStorage="true" in the Manifest (therefore it still works under Android 10). The same with AI2.

But it does NOT work on Android 11+.

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:
