Not sure if this will help you or not.
So, anybody know how to send stuff from an android device to a microcontroller through a usb cable?

Almost there.

USB to UART chip ?
There was some catch with android not really having any usb drivers, so you can't just hook up an FTDI or similar to it.
What people seem to prefer to use is the android IOIO, but I think it's too big for some applications.
In my opinion, the easiest way to go by is getting one of those cheap bluetooth serial port profile (SPP) modules. They can be configured with very simple AT+ commands and just behave like a serial port in android (see [url=http://developer.android.com/guide/topics/connectivity/bluetooth.html]this[/url]).
Here's one really cheap one: [url]http://www.ebay.de/itm/Neu-Wireless-Serial-port4Pin-Bluetooth-RF-Transceiver-Module-RS232-mit-Backplane-/261057313617?pt=Wissenschaftliche_Ger%C3%A4te&hash=item3cc83a7b51[/url]

Guys, I need alot of thin electrical wire to work with, where can I buy alot of it for cheap? It has to fit in my arduino/breadboard and I can't buy it at my local hardware/electronics store.

Why? Those pretty much the only place to get it. But if you can buy it online you should get the wires specifically made for breadboards.

If you just want wire get a 100m spool of 0.6mm (23 SWG / 22 AWG)
I got 4 colors of 20 meters each of like AWG 24 or 26 by splicing apart two lengths of telephone of 4 lead telephone wire.
Took me a while, first getting it out then winding it all up but I was watching something in the meantime or listening to music and it was quite therapeutic to spend a couple of hours doing that. Not like I had anything better to do and it was free considering I had the telephone wire at hand.
Solid core is best in breadboards, don't want that shit breaking off and shorting something out.
Also I love dealextreme.

The android phone, and why shouldn't it be able to be master, that doesn't make sense. That would mean that you couldn't interface with any kind of external GPS, Headset or other hardware.
Just designed and breadboarded myself a current limited linear power supply, in the process of building it.
I need to finish my current sink right around the time I have a proper prototype ready so I can start doing some load tests, will post pics when I have something to show.

So my friend wants to start with shit like antenna's and recievers to listen to frequencies and shit, but he has no idea how to start, he prefers something abot cheap to start with.

When it comes to RF there is no real cheap option.
Buying used equipment is the best option but even that can be fairly expensive.
Okay, can you perhaps give me the name or brands of these things he needs.
Is he interested in the electrical side of things such as building or repairing radios or just using them and doing simple stuff like making an antenna, etc.
For the former you really need to have the following:
Oscilloscope with preferably 100MHz of bandwidth or more.
Function and or RF signal generator.
A good knowledge of electrical theory < unfortunately can't be purchased.
Well, he will be using them mostly, not really building them.

If he wants to start off cheap there are lots of SDR's (Software Defined Radios) out there.
A lot of people have been asking basic questions. Here's a great all around book for people who want to learn the basic practical stuff:

Imo it's better than art of electronics that you guys are suggesting for newbies because it's more practical, up to date and it doesn't go into too much theory.
