Yoda Response: Certainly. Security has always been a top priority in my projects, especially in sensitive applications like mobile banking. In one of the banking applications I worked on, we implemented several Android security best practices to ensure data protection and integrity.

Firstly, we used strong hashing algorithms such as SHA-512 to hash user passwords before sending them to the backend. This ensures that even if the data is intercepted, the original passwords cannot be retrieved due to the irreversible nature of hashing.

We also encrypted all API calls and user data transmitted over the network. This was achieved using HTTPS to ensure that data in transit was secure. Additionally, we implemented SSL pinning by configuring the network security configuration XML file. This involved pinning the server's SSL certificate, which ensured that the app only communicated with servers having the valid certificate hash specified in the configuration. This prevented man-in-the-middle attacks by restricting API calls to trusted domains only.

Furthermore, we disabled clear text traffic in the Android manifest by setting the `cleartextTrafficPermitted` attribute to false. This ensured that the app only allowed secure HTTPS connections, further enhancing data security.

By following these practices, we were able to create a secure environment for our users, protecting their sensitive information and ensuring the integrity of their transactions.
