Android + Facebook SDK

Question

I am trying include facebook authentication into my app. I've created hash key with

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

then i've added this hash into appDashboard.

APK without sign works fine, but when i trying buid signed APK from android studio(Build-Generate Signed APK), i have error about mismatched hashkey...

could anybody help me fix this problem? Thx!

Please refer this page: http://developer.android.com/tools/publishing/app-signing.html

Once you obtain your private key(which should be kept very safely and you should not lose it ever, atleast for 25 years) use that key to sign the application and to generate a hash for Facebook dashboard.

Refer this for steps: https://developers.facebook.com/docs/android/getting-started/ Under Create a Facebook App search this command that uses your release(google dev key)

keytool -exportcert -alias <RELEASE_KEY_ALIAS> -keystore <RELEASE_KEY_PATH> | openssl sha1 -binary | openssl base64

That should do it.
