Not able to Browse PDF files from mobile file system in IONIC Version-1

Hi Team,

Tried many alternatives to browser PDF file from mobile file system in IONIC version 1 with cordova plugin in Android -> 8.0, IOS -> 12.1 devices but its not working in our mobile application.

Is there any approach or any other plugs-in which can help us in browsing this ?

Looking for your response as soon as possible.

Thanks,
Abhishek
