Answer 1

I know this has already has a selected answer, but it is important to note that if you are trying to use keytool instead of printing the keyhash in code, make sure you use the keytool that comes with java 1.6 instead of java 1.7.

Answer 2

call this below method from oncreate of your activity , it will print a hash key in logcat, add that into hash field in app setting on Facebook. try again it will work

  public void printHashKey() {

        try {
            PackageInfo info = getPackageManager().getPackageInfo("your.package.name",
                    PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.d("TEMPTAGHASH KEY:",
                        Base64.encodeToString(md.digest(), Base64.DEFAULT));
            }
        } catch (NameNotFoundException e) {

        } catch (NoSuchAlgorithmException e) {

        }

    }
