How to prevent reverse engineering of your Android application?

Android apps may be reverse-engineered with a few unique reverse engineering devices. That’s why keeping an android device safe by taking a few measures that avoid code decompilation is critical for a developer. Android reportedly had a cumulative number of 322 security bugs in 2017, according to a study released by Cvedetails. Of these, 23 percent were critical, reported in 2018 and 13 percent allowed malicious code to be performed.

 

Reverse engineering in android

Being an open-source platform, it is fairly easy for an app developer or reverse engineers to review and change their source code at the Android Open Source Project (AOSP) as they wish. The methodology by which most reverse engineers re-obtain source code is known as Reverse Engineering in Android, either to recreate the software, constructing something identical to it, or finding the vulnerability of an app or improving its stability.

 

How to prevent android app decompilation to prevent reverse engineering

  • Put important code on a server
  • Debugger detection techniques
  • Write important parts of code in C/C++
  • Write files natively into .so files
  • Add multi-factor security
  • Be careful while implementing SSL
  • Secure user credential with extra care
  • Encrypt your database to enhance mobile security

 

Conclusion

By securing the above points, one can make Android reverse engineering more difficult for any form of application.
