Add following code to your Activities onCreate and check which hashkey is sent by your app to facebook,

PackageInfo info;
    try {
        info = getPackageManager().getPackageInfo("com.example.yourpackagename", PackageManager.GET_SIGNATURES);
        for (Signature signature : info.signatures) {
            MessageDigest md;
            md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            String something = new String(Base64.encode(md.digest(), 0));
            //String something = new String(Base64.encodeBytes(md.digest()));
            Log.e("hash key", something);
        }
    } catch (NameNotFoundException e1) {
        Log.e("name not found", e1.toString());
    } catch (NoSuchAlgorithmException e) {
        Log.e("no such an algorithm", e.toString());
    } catch (Exception e) {
        Log.e("exception", e.toString());
    }

Answer 2

First Check your hash key with these lines of code given by me at this link Facebook Integration in Android Application and if it is not working yet then please check that your Facebook Android Application in mobile is updated. If the application is not updated update your Facebook application and try to post.

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    facebook.authorizeCallback(requestCode, resultCode, data);
}

Use this code in the activity where you call facebook login request.
