I have recently finished building a Multi-Tier database Application using the datasnap technology in Delphi. I have built the datasnap Client app in Delphi-Object Pascal, and linked it to a datasnap server app that communicates with HeidiSQL. When I run my Client app on the Windows desktop(64bit), it works just fine; it connects to the datasnap server, and can read and update the database. However, when i run it on an Android Device, while the server is running, it closes immediately. Do any of you know how to solve this issue? Thank you in advance.

Below is AES encryption method for Android, what would be the equivalent implementation in delphi for iOS.... I tried using lockbox but I don't getthe same encrypted result. public static String encryptAES(String password, String value) throws GeneralSecurityException, UnsupportedEncodingException { Rfc2898DeriveBytes keyGenerator = new Rfc2898DeriveBytes(password, salt); byte[] key = keyGenerator.getBytes(32); byte[] iv = keyGenerator.getBytes(16); SecretKeySpec secret = new SecretKeySpec(key, "AES"); Cipher cipher = Cipher.getInstance("AES/CBC/PKCS7Padding"); cipher.init(Cipher.ENCRYPT_MODE, secret, new IvParameterSpec(iv)); byte[] cipherText = cipher.doFinal(value.getBytes("UTF-16LE")); return new String(Base64.encodeToString(cipherText, Base64.DEFAULT)); }

Hi, the new iPhones XS & XSMax don't have a standard 40 character UDID anymore. Therefore, Tokyo can't compile and deploy apps to those devices even if you have a valid provisioning profile for those devices. Also iTunes does not provide the UDID anymore for those new devices. The new UDID format for those is in the form nnnnnnnn-000NNNNNNNNNNNNN Then the compiler complains and stops deployment. Anyone found a workaround? Thanks Steve

Interestingly, I've just for my new iPhone XR today and the UUID format has changed from my iPhone 8. Worse still, Delphi Berlin doesn't work properly and fails with an error if I try to debug onto it. Looks like I'll be keeping my iPhone 8 until 10.3 is ready!
