Facebook Auth only works from Webview

My application asks for facebook authorization and so it was working fine with webview. I haven't install fb on my android device. Using fbsdk 3.5

Just to test fb application auth flow, I downloaded fb android application and logged in successfully.

Then I tried my app to use android fb app auth instead of webview but it fails with this error

Bad thing happened UnknownError: ApiException:Key hash pBc2****************MwM does not match any stored key hashes.

I uninstall fb android app and tried doing auth using webview it worked.

FB app auth gave me error on first time here is trace

I dig up the fB sdk and this is what at line 821 

Intent intent = NativeProtocol.createLoginDialog20121101Intent(context, request.getApplicationId(),
                new ArrayList<String>(request.getPermissions()),
                request.getDefaultAudience().getNativeProtocolAudience());
        if (intent == null) {
            return false;
        }

and here is createLoginDialog20121101Intent

public static Intent createLoginDialog20121101Intent(Context context, String applicationId, ArrayList<String> permissions,
        String audience) {
    Intent intent = new Intent()
                .setAction(INTENT_ACTION_PLATFORM_ACTIVITY)
                .setPackage(FACEBOOK_PACKAGE)
                .addCategory(Intent.CATEGORY_DEFAULT)
                .putExtra(EXTRA_PROTOCOL_VERSION, PROTOCOL_VERSION_20121101)
                .putExtra(EXTRA_PROTOCOL_ACTION, ACTION_LOGIN_DIALOG)
                .putExtra(EXTRA_APPLICATION_ID, applicationId)
                .putStringArrayListExtra(EXTRA_PERMISSIONS, ensureDefaultPermissions(permissions))
                .putExtra(EXTRA_PROTOCOL_CALL_ID, generateCallId())
                .putExtra(EXTRA_WRITE_PRIVACY, ensureDefaultAudience(audience));
    return validateKatanaActivityIntent(context, intent);
}

EDIT: Also tried Facebook SDK 3.6 didn't help

I don't find anything suspicious here. Need help to sort this out.

Thanks.

For Linux

Open Terminal :

For Debug Build

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

you wil find debug.keystore from ".android" folder copy it from and paste on desktop and run above command

For release Build

keytool -exportcert -alias <aliasName> -keystore <keystoreFilePath> | openssl sha1 -binary | openssl base64

NOTE : Make sure In Both case it must ask for password. If it does not asks for password that means something is wrong in command.

Now go to -> https://developers.facebook.com

-> Click on "Apps"

-> Select Your App

-> Click on "Settings" on left tab

-> Under "Android" Section you will find input field "Key Hashes"

-> Put the generated hashkey there and save changes.
