This sample app for Android™ illustrates the use of Resource Encryption in PreEmptive Protection™ DashO™. This project can be imported into Android Studio. Control Flow Obfuscation, String Encryption, and Resource Encryption are handled via the DashO Gradle Plugin for Android integration. Renaming Obfuscation and Removal are handled by R8.
This sample is configured with both asset and raw resource encryption on the release builds.
See the main README for the requirements.
Compile, protect, and install the debug version of the application.
- Run the command:
gradlew uninstallAll(if necessary) - Run the command:
gradlew installDebug
If you check for encryption, you will see neither res/raw/quotes.txt nor the images in assets/img have been encrypted.
Compile, protect, and install the release version of the application.
- Run the command:
gradlew uninstallAll(if necessary) - Run the command:
gradlew installRelease
If you check for encryption, you will that res/raw/quotes.txt and most of the images in assets/img have been encrypted.
The sample configuration does not encrypt the images allison-*
This sample has two buttons.
The Random Image button picks a random image from the assets/img directory, determines a sampling size, and displays the image.
A message will display showing the time used to read, decrypt (if needed), and decode the image.
The Random Quote button reads res/raw/quotes.txt and displays a random quote from that file.
To verify if the assets and raw resources have, or have not, been encrypted, unzip the apk.
Look at res/raw/quotes.txt and the images in assets/img.
To enable resource encryption, simply enable the feature in your project and rebuild the application.
Please read through the limitations and provide feedback.
