How to obtain Signing certificate fingerprint (SHA1) for OAuth 2.0 on Android?

Start an export process to create an apk for your app and use your production key. The very last page displays both your SHA1 and MD5 certificate fingerprints

I know this question has been answered but this is how I found my signature for the default keystore. In Eclipse, if you go to Windows -> Preferences -> Android -> Build

I think this will work perfectly. I used the same:

For Android Studio:

1. Click on Build > Generate Signed APK.
2. You will get a message box, just click OK.
3. Now there will be another window just copy Key Store Path.
4. Now open a command prompt and go to C:\Program Files\Java\jdk1.6.0_39\bin> (or any installed jdk version).
5. Type keytool -list -v -keystore and then paste your Key Store Path (Eg. C:\Program Files\Java\jdk1.6.0_39\bin>keytool -list -v -keystore "E:\My Projects \Android\android studio\signed apks\Hello World\HelloWorld.jks").
6. Now it will Ask Key Store Password, provide yours and press Enter to get your SHA1 and MD5 Certificate keys.
