Save issue on samsung s20

[patel]

Use variable for saving and reading

[TIMAI2]

@patel

variable for saving and reading

probably better to use a label, then you can see where it got saved
(nothing wrong with using the evaluate but ignore block though)

[Sirous_Nekooei]

Well, it worked to some extent.
Saving is Ok, but when loading which syntax should be used?

These worked:
file:///storage/emulated/0/Android/data/appinventor.ai_snekooei.write_read_test/files/1.jpg
/storage/emulated/0/Android/data/appinventor.ai_snekooei.write_read_test/files/1.jpg

These didn't work:
1.jpg
/1.jpg
/files/1.jpg
/Android/data/appinventor.ai_snekooei.write_read_test/files/1.jpg

file:///storage/emulated/0/Android/data/appinventor.ai_snekooei.write_read_test/files/1.jpg
/storage/emulated/0/Android/data/appinventor.ai_snekooei.write_read_test/files/1.jpg

just use one of those, which are working, it does not matter which one...

@Sirous_Nekooei

1.jpg

sorry, that tip was wrong... this would display an image from the assets

If → DefaultFileScope is set to → App (default) the → fileName should be (/1.jpg or 1.jpg)

and the path (where the file is saved) is:

/storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/1.jpg

regardless of the Android version.

The Image component needs an absolute or a full path:

Thank you, now it works except something.
Taifun screenshot saving doen't work with error "....No such file or directory"

Any suggestion?

[Anke]

These blocks have nothing to do with your posted aia or your previously posted blocks.

Make a right mouse click on this block (Do it):

and post the result.

[Sirous_Nekooei]

Three files are to be saved. the first and 3rd are save fine. The second fails.

Maybe there is something about Taifun screenshot?
PS: i granted the "permission to write to external memory" on screen initialize, but nothing changed.

[Taifun]

are you using the latest version 2 of the screenshot extension?
https://puravidaapps.com/screenshot.php
does the example project work for you?

--- (This Fails)

Of course, because the (sub) folders don't exist.

The TaifunScreenshot.FileName should be e.g. like this:

ECG_Save2021_11-13-17:08_Short.jpg

[Sirous_Nekooei]

@Taifun

are you using the latest version 2

No, It's V.1.
How can I upgrade it?
If I remove the old one, all related blocks are deleted. I cannot import the new one because there is another one.

[Sirous_Nekooei]

@Anke

Of course, because the (sub) folders don't exist.

So why the other ones work? with exactly the same syntax

[Anke]

Have you tried changing the filename as shown?
If so, does it work? I think so.

[Taifun]

@Sirous_Nekooei

How can I upgrade it?

Import the new version and magically it will upgrade the previous version

[Taifun]

in this case do it manually like this

Image compatibility

you stil can read, but not store files everywhere anymore try the following steps export your project and store it in a save place as backup copy the downloaded aia file and open it using 7zip go to the folder assets/external_comps to manually import an extension, open the aix file using 7zip, you now have two 7zip windows open in parallel drag the main folder of the extension from the aix window into directory external_comps of the project and overwrite the existing old directory of the ex…

If importing of an extensions fails:

Import of TaifunFile Extension Failed!

Open a new project with the new TaifunFile extension and the project with the old extension with e.g. 7-Zip (no need to rename aia to zip): [grafik]

Watch the gif animation here and try the aia, then you will understand:
