The Mini-SDK
During the course of rooting, you'll likely be instructed to go grab the Android SDK.
You very likely don't need that.
If you go and download the whole Android SDK shebang and get a platform tools folder, you'll have everything to begin development in Android. And a big waste of space on your hard drive if you're not into that.
Use
our forums' Mini-SDK and
unzip that to C:\sdk-tools under Windows
- or -
... under an sdk-tools folder inside your home directory or Documents Mac or Linux.
Then, wherever you see instructions telling you to go to "platform tools" - just use your sdk-tools folder and you're all set.
Contents:
- Version.txt
- Windows:
- adb.exe
- AdbWinApi.dll
- AdbWinUsbApi.dll
- fastboot.exe
- md5sums.exe
- Linux:
- Mac OS X:
- sdk.sh
- installer for Linux and Mac OS X only
- To use: sh sdk.sh
Good for both 32/64-bit Windows or Linux, 64-bit OS X. (The only 32/64-bit differences are elsewhere in the full SDK - adb and fastboot are the same regardless. Now aren't you glad you're using the Mini-SDK so you don't have to care?

)
Note to 64-bit Fedora users or others using distros based on that -

HOWTO Setup Android Development - FedoraProject
Note that the md5 checksum utility is included in Linux and Mac OS X but added here for Windows.
On Windows, the commands from inside the sdk-tools directory are:
adb rest of command line
fastboot rest of command line
md5sums filename
For Linux or Mac OS X, please run the installer first -
- unzip sdk-tools.zip, double-clicking in your file explorer or Mac Finder is ok
- sh sdk.sh
On a
Mac from within the sdk-tools folder, to use -
./adb rest of command line
./fastboot rest of command line
md5 filename (see note following Linux)
On
Linux from within the sdk-tools folder, to use -
sudo ./adb rest of command line
sudo ./fastboot rest of command line
md5sum filename (see note following)
Note - on Mac/Linux, adb and fastboot are added to your path by the installer. Thereafter, the ./ file location qualifier won't be needed in new terminal windows.
Windows users please refer to post 1 to get the Mini-SDK into your path, substitute "C:\sdk-tools" as the proper path. You don't need to worry Java or the JDK with the Mini-SDK.
Hope this helps!
