Hi,
This is my code:
showDocument() {
var options: DocumentViewerOptions = {
title: 'A book',
documentView: { closeLabel: '' },
navigationView: { closeLabel: '' },
email: { enabled: true },
print: { enabled: true },
openWith: { enabled: true },
bookmarks: { enabled: true },
search: { enabled: false },
autoClose: { onPause: false }
}
this.docViewer.viewDocument('assets/arabic.pdf', 'application/pdf', options);
}
Fo course I did not forget to import 
import { DocumentViewer,DocumentViewerOptions } from ‘@ionic-native/document-viewer’;
And in the HTML:
I added a button to call the function.
But when I run it (emulation), the click does not make any action (the triggering works fine since I added an Alert and it showed up).
What am I missing??

Did you remote debug the problem on the device already? Follow these instructions here to debug the problem in Chrome dev tools: https://ionic.zone/debug/remote-debug-your-app#android Look at the console and network tabs for errors.
Does the file exist?
Is the path correct?
Tried https://ionicframework.com/docs/native/document-viewer/#canViewDocument?
Yes true, this is what I got when I have debugged:
Did you fix this? Getting this on Android also. The documentation is wrong

It is the same bug. True, documentation is wrong and the plugin is not working but I think only with new android (mine is 7). I am wondering where is Ionic Team!
Any Solution? Still getting the same problem. Working fine on the iOS platform but in Android showing below error message
