I have established security standards and would like to share the measures I have taken:

1. **Secure Communication**: I ensure that all network communications utilize HTTPS. I employ SSL/TLS certificates and certificate pinning to prevent man-in-the-middle attacks.
2. **Secure Data Storage**: I use Android's encrypted shared preferences and encrypted file APIs to securely store sensitive information, minimizing the storage of such data on the device.
3. **User Authentication**: I implement secure authentication protocols like OAuth 2.0 and OpenID Connect to guarantee safe user authentication.
4. **Secure APIs**: I utilize token-based authentication, such as JWT, for API requests and securely manage token storage and refresh as necessary.
5. **Code Obfuscation**: I apply ProGuard or R8 to obfuscate code, making it more challenging for attackers to reverse engineer the application.
6. **Application Components Security**: I restrict access to content providers using permissions and ensure that data is validated and sanitized properly.
7. **Explicit Intents**: I prefer using explicit intents whenever possible and validate received data to prevent intent spoofing.
8. **Broadcast Receivers**: I use local broadcasts for internal communication to avoid exposing receivers to other applications.
9. **Permission Management**: I limit permission requests and clearly explain to users why specific permissions are necessary. For instance, if read contacts or read SMS permission is required, I inform users of its purpose.

I have implemented these techniques to ensure robust security in Android applications, thereby protecting users and their data.
