Ok so you have a app which saves a file and need to be opened by another app which is yours or someone else's?
Are you sure? I don't think so.
I've posted a lot about this subject.
Here is just a small selection:
And tell us which file is saved - media [jpg, png, mp3,...] or non-media [txt, csv, pdf,...].
you have to save it to shared storage
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.
