Save a text file or an image (Canvas) in the ASD & share it on all Android versions

[Anke]

How to save a file (text, Canvas: image) read and share it on all Android versions.

Note:
You cannot share a text file from the → Private dir (internal storage):

/data/user/0/<packageName>/files/

great guide, thank you!

as alternative it might make sense to provide a tutorial, which stores text files or the image always in the ASD for all Android versions, so later when App Inventor targets API30 in late 2021 the app still will work...

This app (tutorial) will also work (for all Android versions) when AI2 is targeting API 30 → targetSdkVersion = 30.

[Taifun]

yes, correct... the example to store something still will work fine... sorry, I was not precise enough...

what I'm talking about is you will not be able to access the previously stored text files or images anymore outside of the ASD....
therefore it makes sense to use the ASD for all Android version already now rather than still storing in other directories

EDIT: you will only have to adjust the canvas part to always store in the ASD...

Correction: It is possible!

I created these blocks from scratch and adapted them to the new File component and the new file system. I'm still wondering whether I should update it here or create a new guide.
Any suggestions from you guys on this?

See how it works here:

Is there any wrong here ( Greater than sign )?

Error 2103 with permission enable

What i understand is that we use

if the sdk > 29, So this sign must be less than ( < )

This guide was made before the nb187 release (and of course before nb188) and is therefore no longer up-to-date.

Thank you @Anke for your efforts
How can we save the csv file to the phone memory?

@sherif_hassan

I answered it in the Kodular community.
(But with AI2 it is different.)

[Anke]

For AI2 (since the nb188 release) this is all you need to save a text file in the ASD (or in my example in a sub-folder of it) on all Android versions:
