Question

I could able to download and open that PDF using PDF reader before targeting Android 11. Now PDF download to the app specific storage location. According to the new policy other third party apps have no access to that location. So how can I open and show that PDF? There is no specific direction to follow. Is there any way to open the PDF without saving it? PDF data coming as a byte[]

You can check the path settings you are using, For more information, please see https://developer.android.com/about/versions/11/privacy/storage#file-directory-restrictions
