Generating a fingerprint for spotify android api [duplicate]

Question

I am reading an development guide of Facebook Developers at here

It says that I must use keytool to export the signature for my app such as:

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

I do not know how to find the keytool in order to run it. I tried to open a Windows command prompt and paste the above command, but it did not work.

Answer 1

I found a solution by myself as below quote. It works fine.

"C:\Program Files\Java\jdk1.6.0_26\bin\keytool.exe" -exportcert -alias
> sociallisting -keystore "D:\keystore\SocialListing"  |
> "C:\cygwin\bin\openssl.exe" sha1 -binary | "C:\cygwin\bin\openssl.exe"
> base64
