Create Android chat message App with End to End AES(Advanced Encryption Standard) method in Firebase

This is a rather a long video (around 1 hour) but it shows complete steps to create an Android Message App with End to End Encryption using AES (Advanced Encryption Standard) method in Firebase Database from scratch. In this video it shows first the steps to create a Firebase database connected to your Android App. Then it moves on and shows how to create a simple layout of your App in Android Studio. Once the above basics are done then it shows the main coding part. Various settings of gradle files are shown and then Java coding for accessing the database and encrypting and decrypting the messages are shown. For encryption and decryption the AES instance of Android Cipher is used. The message string is first converted into Byte, then encrypted using AES method and then encrypted byte is converted back to String using a standard character set. This encrypted byte string is then stored in the Firebase. So, as the data stored in the Firebase database is in encrypted form, even if anyone is able to get the access to the database, the actual message will not be readable by the person until s/he has the encryption method and key available with him. Similarly, on the decryption side, the received string from the database is converted back to byte using the same character set (used on the encryption side). Once the encrypted byte data is available, then the decrypt mode cipher is used to decrypt the data. The decrypted data is then converted back from byte to String readable format. Then that output string, after sorted out in chronological order, is displayed in the listview of our App layout for the user to see. So, to summarize this is an end-end message App tutorial. This will be helpful for anyone who wants to quickly start building their own chat message App. This video is continuation of my initial video tutorial, which showed the process to create the chat App without any encryption.
