问题
I am trying to download a file from server to Download folder of andorid
As expected it is working fine
Problem
When user clones my app (dual app) , the cloned app (2nd app) throws SecurityException: Unsupported path /storage/emulated/999/Download/somefile.pdf
Research
Device : Redmi 5
App : File Manager (system app)
I found 2 options
- Internal Storage
- Storage for dual apps (it also has Download folder & other apps folder like Whatsapp)
Still my app throws SecurityException
