how to pdf file open in ASD directory

you can’t use an external app to read a file from your ASD…therefore

1. first copy it to shared storage like /Download and read it from there, or
2. use one of the pdf reader extensions to read it from ASD, for example App Inventor Extensions: Pdf | Pura Vida Apps

That’s because you’re downloading to this path:

And then reading the file from a different one.

You are downloading to:
ASD/Downloads/ms/manish.pdf

And trying to read from:
ASD/manish.pdf

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…

that the ASD is only accessible by your own app, but not for other apps like pdf readers

@Lollipop Read the complete thread to find out, that another app (which has been started by the activity starter) can’t access the ASD of your app… i e. it is not working

How to open a pdf file from asd in a third party app using activity starter?

It’s not clear to me to what extent this is supposed to be a solution. It is of course no problem to open the PDF with the same app (let’s say App1). However, that is / was (?) not the topic. It’s about opening this PDF file with another app (let’s say App2) from the foreign ASD (app1). And that’s definitely not possible with the APK.

And why do we have to discuss this again in another thread?

According to Some basics on Android storage system it is not possible.

The Activity Starter enables you to call another app, here a pdf reader. The pdf reader app now must read a pdf file, which is stored in the ASD of another app (your app).

Just add a screenshot of an example project, which uses the activity starter to read a file from the ASD into this thread including aia file, so everyone can check… Thank you…

Hi Taifun, i shared this .aia:
PdfCreator.aia (19.9 KB)

When Screen1 Initializes it creates just a bunch of labels on an arrangement
When Button 1 is Clicked it will use AdvancePDFCreator extension by @shreyaa
to generate a pdf inside the ASD directory
When the file is generated it will use Activity Launcher to open the file in ASD with an external app.

I’ve tested it on companion and on a generated apk on a Xiaomi Note 11 (Android 11):
The app doesn’t have any permission enabled:

And the pdf reader (wps office and google drive) have enabled media files read permissions (not all file permission).

I understand the basics of the new storage system. I don’t know if i’m wrong but as far as i’ve researched The ASD directory is encrypted and can only be decrypted by the app itself.
If you try to open the file with an external app it is not possible because of that ecryption. But when done trough an Activity you’re sending that file specifically, uncrypted and capable of being read by the external app.
