Use "adb logcat" to look at the Intent the programs you are interacting with are trying to start. The platform does not allow the user to tap on arbitrary files with unknown MIME types on the SD card, so there is no standard convention for this.
For icons on the home screen, you can have an activity that allows the user to pick a shortcut (like the settings shortcuts etc) that would build an Intent that launches your specific activity with the data set to the file it should use. For that case your activity doesn't need any intent filters, since the shortcut points directly to it.
