java - ParseLoginUI Facebook Integration - Stored Hash Keys Don't Match -

i've been following parseloginui tutorial here: https://github.com/parseplatform/parseui-android/tree/master/parseloginsamplewithdispatchactivity

in androidmanifest.xml, have:

<activity     android:name="com.parse.ui.parseloginactivity"     android:label="@string/app_name"     android:launchmode="singletop">     <meta-data         android:name="com.parse.ui.parseloginactivity.parse_login_enabled"         android:value="true"/>     <!--<meta-data-->         <!--android:name="com.parse.ui.parseloginactivity.parse_login_email_as_username"-->         <!--android:value="true"/>-->     <meta-data         android:name="com.parse.ui.parseloginactivity.facebook_login_enabled"         android:value="true"/>     <!--<meta-data-->         <!--android:name="com.parse.ui.parseloginactivity.twitter_login_enabled"-->         <!--android:value="true"/>--> </activity> 

...and:

<meta-data     android:name="com.parse.application_id"     android:value="@string/parse_app_id" /> <meta-data     android:name="com.parse.client_key"     android:value="@string/parse_client_key" /> <meta-data     android:name="com.facebook.sdk.applicationid"     android:value="@string/facebook_app_id"/> 

in globalapplication class, have:

parsefacebookutils.initialize(this); 

i realize looks hash key problem, i've tried hashing , re-hashing using various methods found here: key hash android-facebook app

i'm hoping it's not trivial messing hash keys, because i've triple checked these. there wrong code?

what problem here? see attached image below:

i figured out! helps others well. there nothing wrong way generated hash keys. wasn't using signed release build while testing facebook hash. make sure generate signed apk, copy apk phone , install it, open app. when attempt login facebook still see error, displayed correct hash key, , want add exact value facebook app dashboard production hash!
