The published "Hello World" is not working for me on Android

I don't know why it says goodbye ... I say hello!

The code:

   mByteButton.setOnClickListener(new OnClickListener() {
      @Override
      public void onClick(View v) {
        try {
          ParseService.removeObserver(mOnSystemStateChange);
          Class<?> dynamicType = new ByteBuddy()
          .subclass(Object.class)
          .method(ElementMatchers.named("toString"))
          .intercept(FixedValue.value("Hello World!"))
          .make()
          .load(getClass().getClassLoader())
          .getLoaded();
          //assertThat(dynamicType.newInstance().toString(), is("Hello World!"));
          assert dynamicType.newInstance().toString().equals("Hello, World!");
        } catch (IllegalAccessException e) {
          throw new RuntimeException(e);
        } catch (InstantiationException e) {
          throw new RuntimeException(e);
        }
      }
    });

The angry phone:

You would need to add byte-buddy-android and use the AndroidClassLoadingStrategy as second argument to load for this to work.
