Android – Invalid Key hash with Facebook Android SDK

adtandroideclipsekeytool

I'm trying to use Facebook Android SDK to develop a simple app with the Facebook Login Button.
But i'm having trouble with Key Hashes. I've created both a debug key and a release key:

Debug key:

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

Release key:

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

And then i copied this key hashes in the Facebook Developers page.
When i export the apk and copy it into the device it works well, but when i try to install the app from Eclipse (run as/debug as Android Application) it doesn't work. It seems that the app is using a different key hash from the one i've created with keytool.
Anyone knows how to solve this problem?

Best Solution

Try to get the HashKey from here 

public static void showHashKey(Context context) {
            try {
                PackageInfo info = context.getPackageManager().getPackageInfo(
                        "com.example.tryitonjewelry", PackageManager.GET_SIGNATURES); //Your            package name here
                for (Signature signature : info.signatures) {
                    MessageDigest md = MessageDigest.getInstance("SHA");
                    md.update(signature.toByteArray());
                    Log.i("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                    }
            } catch (NameNotFoundException e) {
            } catch (NoSuchAlgorithmException e) {
            }
        }
