nit: I don't think this file should have tabs in it.

[Vivian, 2016/07/25 21:51:44]

Done.

also maybe include .mht and .eml?

[Vivian, 2016/07/25 21:51:44]

I added .mht and .eml. Not sure if .eml is actually supported. I tried both
change file extension from .mhtml to .eml and download an sample .eml file, and
opened them. There is no problem with .mht files. But instead of opening .eml
file, Chrome would trigger download.

Do you know what might cause the issue? I have the same problem opening .mhtml
file from Android's storage manager.

duplicate section?

[Vivian, 2016/07/25 21:51:44]

These two sections differ in the line <data android:mimeType="*/*"/>.
Xender would only work with the second filter while ShareIt would only work with
the third one.
