You can try Ionic FileOpener

  this.fileOpener
        .open(filePath, fileExtension)
        .then(() => {
          return true
        });

the best approach would be Document Viewer

Document Viewer

This plugin offers a slim API to view PDF files which are either stored in the apps assets folder (/www/*) or in any other file system directory available via the cordova file plugin.

$ ionic cordova plugin add cordova-plugin-document-viewer
$ npm install --save @ionic-native/document-viewer


import { DocumentViewer } from '@ionic-native/document-viewer';

constructor(private document: DocumentViewer) { }

const options: DocumentViewerOptions = {
  title: 'My PDF'
}

this.document.viewDocument('assets/myFile.pdf', 'application/pdf', options)

          this.filePath.resolveNativePath(uri)
            .then(file => {
              this.fileDir = file;
              this.fileName = file.substring(file.lastIndexOf("/") + 1);
             // open the pdf
             })
            .catch(err => console.log(err));
        }
      )
      .catch(error => {
        this.showError(error);

          .then(url => {
            console.log(url)
            // url is path of selected file
            var fileName = url.substring(url.lastIndexOf("/") + 1)
            console.log(fileName)
            // fileName is selected file name
          })
          .catch(err => console.log(err));
      }
    )
    .catch(error => {

    });
