DexProtector (https://dexprotector.com) is one of the pioneers in mobile application and library shielding. It protects and obfuscates Android and iOS applications and libraries. Our solution helps you to secure your code and assets against unauthorized or illegal use, tampering, reverse engineering, and cracking.

This sample is to demonstrate how the AAR protection works

Description

https://dexprotector.com/docs#aar-protection

Requirements

• Android Studio or Gradle
• NDK
• DexProtector Enterpise with a valid license

Configuring

• Set path to Android SDK in local.properties
• Set path to DexProtector Enterprise in build.gradle (project’s root) instead of /Users/developer/DexProtector

Building

Building Sample Android Application Library

cd AndroidApplicationLibrary/SampleLibrary/lib
<ndk-dir>/ndk-build
../gradlew clean assembleRelease
cp build/outputs/aar/lib-release.aar ../../SampleApp/app/libs/lib-release.aar

Building Sample APK

cd AndroidApplicationLibrary/SampleApp/app
../gradlew clean assembleRelease

Evaluating

adb install -r build/outputs/apk/app-release.apk
adb shell am start -n com.dexprotector.aar.app/.MainActivity

When the Sample application is started the following protection features are demonstrated:

• Initialization and use of the library’s methods that are protected with
  • String Encryption
  • Hide Access
  • Class Encryption
  • Resource Encryption (available only for files from assets)
  • JNI Obfuscation
  • Native Library Encryption
• Use of the Environment checks and device attestation
