[Android] Hooking Java from Android app itself?

[RusJJ]

Hi there! I love to mod Android games. And no, im not starting to create some ass cheat. I want to implement a patch for the game without changing the APK itself. How can i use frida core to do that directly on a smartphone WITHOUT ROOT and on the same application it runs?

If I read it correctly than this is obviously not supported on normal android.
