Key hash for Android-Facebook app

Question

I\'m working on an Android app, in which I want to integrate a Facebook posting feature. I downloaded the Facebook-Android SDK, and I got the readme.md (text file) in there,

Answer 1

This is what is given at the official page of Facebook:

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

Let me break this command into fragments.

1. Look for "keytool.exe". You can search that on the C: drive. You can find it in "java jdk" or "java jre". If you have installed multiple versions, choose any.

2. Open a CMD prompt and go to the above directory where you found "keytool.exe".

   Clip the "exe`" and paste the above command provided on the Facebook page.

3. You will get an error on entering this that OpenSSL is not recognized as in input output command. Solution : Download "Openssl" from OpenSSL (if you have a 64-bit machine you must download openssl-0.9.8e X64). Extract and save it anywhere... I saved it on the C: drive in the OpenSSl folder

4. Replace the openssl in the above command in which you was getting an error of OpenSSL with "C:\OpenSSL\bin\openssl" at both the places after the pipe, "|".

5. If prompted for a password, enter android.

And you will get your hash key. For further steps, refer again to the Facebook page.
