Android devices and pdf docs (attached files or URLs)

Has anyone found a workaround for android users being able display pdf docs from within an app?

I have tried making the column a file attachment, as well as an external web link since the pdf is on our website. The files load on the browser and Iphones, but not android.

Any suggestions?

I use android (Pixel 1st generation) and if I click on a PDF attachment it loads and I can view it. If I hit the back button while viewing I return to the record.
