DexProtector 9.1 Released

We are proud to announce the release of DexProtector 9.1. Alongside the protection and obfuscation for Android Applications (APKs), Android Libraries (AARs), iOS applications (IPAs) and Frameworks (.Framework), DexProtector is now capable of protecting Android Application Bundles (AABs).

The Android Application Bundle is a new app publishing format. It is more efficient in terms of building and releasing your apps. The Android App Bundle makes it easier to deliver optimized and smaller apps to your application's users. Its goal is to improve the user experience of Android users as at least the applications will become smaller, and they will only contain the required resources. According to independent research, the size can be potentially optimized to up to 50%.

This is a crucial functionality, so the support for Android App Bundles is available for both DexProtector Standard and Enterprise versions.

The support of the Android Gradle Plugin for AABs is at the experimental stage now. We would recommend using DexProtector's CLI to protect your AABs (protection features that are available depend on the version you are using).

The full list of changes:


  • Added support for applications built with earlier versions of XCode
  • Improved protection mechanisms for SWIFT applications


  • Added experimental support for AABs (Android Application Bundles)


  • Fixed incorrect behavior of internal protection mechanisms for Android Emulator (x86_64)

  • Experimental support for Kotlin meta-data structures' protection and shrinking


  • Added detections of the latest versions of Magisk

  • It is now possible to use external res/xml network_security_config.xml for Android Libraries (AARs)
