VirtualHook is a tool for hooking application without root permission. It is based on two projects:

• VirtualApp. It's a plugin framework which allows running applications in its virtual space.
• YAHFA. It's a hook framework for ART which allows hooking Java method of the application.

Since YAHFA supports Android 6.0 and 5.1, currently VirtualHook would only run on those platforms.

Build

Import and build the project in Android Studio(with Instant Run disabled). There are four modules:

• app. This is the VirtualApp application module.
• lib. This is the VirtualApp library module.
• YAHFA. This is the YAHFA hook module.
• demoHookPlugin. This is a demo hook plugin which compiles to an APK.

After building the APKs, push the demoHookPlugin APK to device at /sdcard/io.virtualhook/patch.apk and run the main application. The hook plugin would be applied to all applications running in VirtualApp.
