How to show pdf in read only mode In Android

faizan shoukat

As i have 3 options to show pdf file in android Like:

1)Webview 2)Action_View using Intent 3)using this library 'com.github.barteksc:android-pdf-viewer:2.8.2'

In web view there are some default options which i do not need. Using intent showing pdf file in pdf viewer or word app which gives aloot of option. And the last one,library is not working in android x.

Kindly give solution to show just only pdf in android without any share,download etc type option. Image Using Webview Image Using Intent
