public void generateHashkey(){
        try {
            PackageInfo info = getPackageManager().getPackageInfo(PACKAGE, PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                String s = Base64.encodeToString(md.digest(),
                        Base64.NO_WRAP);

                Log.e("HASH KEY ", s);
            }
        } catch (PackageManager.NameNotFoundException e) {
            Log.d("Name not found", e.getMessage(), e);

        } catch (NoSuchAlgorithmException e) {
            Log.d("Error", e.getMessage(), e);
        }
    }

try to generate the hashkey then copy paste it to developer console facebook.

you can call it in onCreate – Shailesh Bandil Aug 16 '17 at 13:20
and check log to see the HashKey and the copy that value – Shailesh Bandil Aug 16 '17 at 13:21
Actually as the error it self says that Invalid HashKey cos it not found in store key hashes so you have to create a hash key and than save it to your developer console – Shailesh Bandil Aug 16 '17 at 13:55
and the Key that your have save to the developer console and the key which is generated form the apk and checking to the console key did not matched so for that you are getting this error – Shailesh Bandil Aug 16 '17 at 13:57
