How to read a pdf file from ASD with Activity Starter?

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…
