Ionic Android PDF Viewer
Raw
ionic_android_pdf.md

Below are options for android pdf viewing. Android does not have a native pdf viewer but there are options with tradeoffs. In all cases, pdfs would need to be temporarily stored unencrypted (we can delete this file once we are done viewing)

InAppBrowser

Uses google docs to view (https://docs.google.com/gview?embedded=true&url='')

  • 👍 zoom in/out functionality
  • 👍 able to hide url navigation bar
  • 👎 pdf's must be online

Pdfjs (Ng page viewer)

bare bones viewer (https://github.com/VadimDez/ng2-pdf-viewer)

  • 👍 renders local pdfs
  • 👍 customizable
  • 👎 no pinch to zoom. add a button to do this manually
  • 👎 sluggish

Cordova plugin document Viewer (can be used with file opener2)

https://github.com/sitewaerts/cordova-plugin-document-viewer

  • 👍 view offline pdfs
  • 👎 third party app download required to open (muPDF)

pspdfkit

Feature rich paid for library (https://pspdfkit.com/)

  • 👍 clean ui
  • 👎 expensive. ~ $500 yearly subscription.

Incompatible (deprecated libraries)

android navtive pdfviewer
