= Android Development On ORBIT =

== 1. Setup computer ==

The ssh connection will use [http://help.unc.edu/830 X11 forwarding] to display programs on your computer that are running on a remote serve (in this case, an ORBIT node.)

If you are using Linux, ssh and the X window manager are included, so you can skip this section.

If you are using Windows, install [http://sourceforge.net/projects/xming/files/Xming/6.9.0.31/ Xming] and download [http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html PuTTY].

== 2. Reserve timeslot ==

Go to the [https://www.orbit-lab.org/schedule/ scheduler] and reserve a timeslot

== 3. SSH to console ==

If you are using Linux, connect using ssh with the X11 forwarding flag
{{{
ssh -X [username]@console.[grid].orbit-lab.org
}}}

If you are using Windows, first start the Xming window system.
Open PuTTY and turn on X11 Forwarding in Connection > SSH > X11
Now connect to console.[grid].orbit-lab.org through PuTTY.

== 4. Load android image ==

Now you need to load the android development image on a node to work on. You can use 
{{{
omf stat
}}}
to see which nodes are available. To turn a node on or off, use
{{{
omf tell command [x,y]
}}}
where command is on, offh (hard power), or offs (soft power) and [x,y] is the node.

Choose a node to image (try node2-10... this is a quad-core core processor), preferably a quad core node that can handle Eclipse remotely, and load android2.ndz onto it.
{{{
omf load [x,y] android2.ndz
}}}
where [x,y] is the node.

It will take several minutes, and omf will turn the node off when it is complete.

Turn the node back on and ssh into it with X11 forwarding
{{{
ssh -X root@nodex-y
}}}
Now you are in the android development image!

== 5. Start Working ==

You can start eclipse from the command line using
{{{
eclipse &
}}}
A new Eclipse window that is running on the node should be on your screen!

The & lets you continue to use the same terminal for more commands. Otherwise you would have to close Eclipse to do anything else.
The image has Java 6, Eclipse, Android SDK, and an ARM cross-compiler.
