Facebook keyhash error after signing the android app

Question

I have an app with facebook integrated. it works fine when i run it from eclipse but after signing the application i get this error

 Login failed: invalid_key:Android key mismatch.
Your key "JGn9F2vDQ/w6hexLxdefCUpxYIA" does not match the allowed keys specified in your application settings.
Check your application settings at http://www.facebook.com/developers

I have checked key hash generated by my application and one on www.facebook.com/developers is same. Please help!

How you are generating hash key ? – Lavekush Agrawal May 14 '14 at 18:12 — Lavekush Agrawal, May 14 '14 at 18:12

You can try this for generating hash key:

 // Put this code on oncreate method

try {
    //Replace your.package.name with your base packege name.
    PackageInfo appPkgInfo = getPackageManager().getPackageInfo("your.package.name", PackageManager.GET_SIGNATURES);


    for (Signature signature : appPkgInfo.signatures) {

        MessageDigest messageDigest = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());

        // See Logcat for your hash key and put in on Facebook developer console.
        Log.d("Your Hash key", Base64.encodeToString(messageDigest.digest(), Base64.DEFAULT));
    }
    } catch (NameNotFoundException e) {

    Log.e("ERROR",e.getMessage());

    } catch (NoSuchAlgorithmException e) {

    Log.e("ERROR",e.getMessage());

}

have you check your base package name given in code and facebook developer all those are need exactly same. — Lavekush Agrawal, May 14 '14 at 18:35
