Help for file component and SAF Extension

[Technical_Zone (Sunil Kumar)]

Hi there,
Hope you all are doing well

I wanna created a folder inside /storage/emulated/0/Download/ with file component But Something is wrong as neither folder nor file is created. Please correct me out someone.

---

Permission took:

Blocks Used:

PROBLEM1 : TimeManagerDB folder is not created.

PROBLEM2 : Text file is not created. (I think, because of PROBLEM1)

See why

SAF: App Inventor implementation of Storage Access Framework

Yes, and you can’t access it either: /storage/emulated/0 (the root dir of the external storage) and /storage/emulated/0/Download But you can access: /storage/emulated/0/Downloads

[Technical_Zone (Sunil Kumar)]

Hi @dora_paz, Thanks for quick response
Let me try with /storage/emulated/0/Downloads

[Technical_Zone (Sunil Kumar)]

@dora_paz I tried with /storage/emulated/0/Downloads/TimeManagerDB

but still no folder created by File Component…

@Technical_Zone

/storage/emulated/0/Downloads/TimeManagerDB

This should work (without storage permissions (WRITE permission) on Android 11+):

Of course, on Android < 11 you have to request WRITE permission.

Thanks @bodymindpower and @dora_paz…
I found that on replacing /Download to /Downloads
The folder TimeManagerDB was created inside /storage/0/Downloads but it was only visible through ES File Explorer deep search.

Can you please help me out with PROBLEM2? @dora_paz

@Technical_Zone

PROBLEM2 : Text file is not created.

[vknow360 (Sunny Gupta)]

The actual problem is that you are trying to use file paths in SAF extension which accepts URIs.
Please read the extension thread to learn more about its usage.

[Technical_Zone (Sunil Kumar)]

Hi, @vknow360 Glade to see you here,…
Can you please help me out, what to put in URI, I seen all the documentation but didn’t understood URI please let me know what to enter in that?

[bodymindpower (Anke)]

@Technical_Zone

PROBLEM2 : Text file is not created.

[Technical_Zone (Sunil Kumar)]

Very Thanks Anke, Let me see if that works for me.

Hi @bodymindpower Anke
I tried this and the forder TimeManagerDB is successfully created inside Download folder of phone. But When creating text file it says:
ERROR 2103 : file can’t be created.
All Blocks I used are same as yours.
Android 10

@Technical_Zone

I tried this and the forder TimeManagerDB is successfully created inside Download folder of phone. But When creating text file it says:
ERROR 2103 : file can’t be created.

Try this, it should save the text file here (on all Android versions):
/Download/TimeManagerDB/myText1.txt

test2.apk (5.4 MB)

On Android 11+ this should work without storage permissions. On Android < 11 WRITE permission is requested automatically.

Note: To make sure it works, first remove this folder from your test device:
/Download/TimeManagerDB/

How did you make this possible to grant Write External Storage automatically for android 11?

@Vinscent_Joshua_Dy-Cok

to grant Write External Storage automatically for android 11

This permission does not exist anymore for Android 11

Saving an image also works on newer devices. Please elaborate and provide a screenshot of your relevant blocks

Really? If yes, what’s the better extension to save image for android 11 and later?
