When you want to open files inside your Ionic app you’ll most likely have to interact with the local filesystem in some way – something that’s not always easy and obvious from the outside.

In this Quick Win we will build an app to open both a PDF that we supply with our app and one that we first download and then display. In contrast to the previous version for Ionic 3 we will now have a switch between iOS and Android to handle things differently.

With the previous Document Viewer plugin we had to use a specific app on Android, so this time we are rolling with a more general plugin that will automatically use your preferred reader.
