How to mount an Android Device on i3?

I am using i3 windows manager on Ubuntu 14.04. When I do lsusb I see:

Bus 001 Device 007: ID 04e8:6860 Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II], GT-I9300 Phone [Galaxy S III], GT-P7500 [Galaxy Tab 10.1]

When I try adb device -l I don't see anything.

Unity automatically mounts my android devices, but i3 doesn't.

I see some solution ideas here and here. Both require me to install new things. Since Unity could mount my devices by itself, I wonder if I really need to install anything new. May be there is a more natural solution. And I am already using udisk-glue to auto-mount my external HD.

So question is: How do I mount my android device without having to install too many new things, given that I already have Unity and udisk-glue

Here is a related question.

EDIT: I tried the above anyways. Here are issues: 1. Go-mtps is available only till Ubuntu 12.04. I can't install it on 14.04. 2. I am unable to find my idVendor and idProduct as instructed here because what the hell is mtp-detect? mtp-detect is not available on 14.04! And since I intend to be mounting my phone on i3 I suspect the USB system handler will be different from what is given in the instructions. I would still need help! Lot of help! Please help!
