How do I have a new file type launch my app?
For example if I have a new file type 'file.mjl' and I receive this file as an email, I want Android to associate this file type with my app and allow me to open / save it.
You need to add an intent-filter
to the activity you want to launch to work with that file. Here is a link to a great example on that subject:
