Fixes #33
I could really use some help from an Android developer on this one, because I just "made it work", don't know how to "make it work good".
Some things that should be reviewed:
- [ ] validate Android 5.0 devices (my emulator work, but outputs some weird sounds; a Galaxy 4 I tested on crashes)
- [ ] validate Android 5.1 devices (emulator works, couldn't find a real device)
- [ ] how to handle File Extensions? (https://www.w3schools.com/tags/att_input_accept.asp)
I'm sure that there's more refactoring to be done, so any help and advice would be appreciated.
