When the file is located on the device you can open it in several ways, using the local URI:
- in a object
element with the respective URI as a source (for both platforms this should trigger the suggestion for an app that supports the flie type)
- using the InAppBrowser
- using a custom plugin (this is Android only - https://www.npmjs.com/package/cordova-plugin-fileopener and I am not aware of such for iOS)
Let me know if this works for you.
