To ensure Android application security wise what I did was one is to establish secure communication Like you can ensure all the network communication uses the valid HTTPS to encrypt data in transit like Like you can use any certification pinning as well in the servers SSL TSL certificate to prevent any Man-in-the-middle type of attacks and secure your application then you can also make use of secure data storage like Encrypted storage like use Android's encrypted shared preferences and encrypted file APIs to store sensitive data securely and you can avoid storing Sensitive data like I minimized the storage of sensitive data on the device Unless necessary and I made use of encryption techniques and sometimes I made sure that the user authentication is secure by using the OAuth and open ID connect like use a secure authentication protocols like OAuth 2.0 and You can use open ID connect for any user authentication these guys these sort of things and One more technique I can remember is I made use of secure APIs like token based authentication Like a JWT or the token for API request and ensure that tokens are securely stored and refreshed as needed that is one approach I made and Made sure that I used code obfuscation as well Like use pro guard you you can use make use of pro guard or re to obfuscate your code Making it harder for any attackers to reverse engineer or applications This is one thing and you can also make use of Application components to secure like content providers You can use permissions to restrict access to content providers and ensure that the data is properly validated and sanitized And I made use of explicit intents wherever possible like you can validate the data received to avoid any intent spoofing and In broadcast receivers also you can make use of local broadcasts for internal communication to avoid any exposing receivers in other applications and Proper permission management should be there like request like you can use minimize the permissions request only if the necessary permissions and explain to users Who are using my application like the customers? Why they are needed like specific permissions if I am using read contacts read SMS permission and all I will tell them the Particular usage of those application Permissions in my application so as to why I am trying to use those permission permission to retrieve their data So I can provide those kind of information while using to while trying to implement those permission as well Yes, these are some of the techniques. I know I have implemented and Mainly one can make use of this to ensure good credibility in terms of security measures in trying to develop an Android application
