Open pdf file on any android device
===

I am developing an app that downloads `PDF` files from the internet and opens them. I observed that if I have an app that is capable of opening `PDF`s, it works fine (I send an intent to the OS with `Intent.ACTION_VIEW`). On the emulator for example, I have no such app installed. **But** I want to show the user that `PDF` somehow, on any device. I need a general solution that works on any Android device, preferably without any external apps. Is it possible?
