In the same way that we created ActivityHandler to process application events in Chapter 5, Writing a Fully Native Application, create jni/InputHandler.hpp to process input events. The input API is declared in android/input.h. Create onTouchEvent() to handle touch events. These events are packaged in an AInputEvent structure. Other input peripherals will be described later in this chapter:

#ifndef _PACKT_INPUTHANDLER_HPP_
#define _PACKT_INPUTHANDLER_HPP_

#include <android/input.h>

class InputHandler {
public:
    virtual ~InputHandler() {};

    virtual bool onTouchEvent(AInputEvent* pEvent) = 0;
};
#endif

Modify the jni/EventLoop.hpp header file to include and handle an InputHandler instance.

In a similar way, to activity events, define an internal method processInputEvent(), which is triggered by a static callback callback_input():

...
#include "ActivityHandler.hpp"
#include "InputHandler.hpp"

#include...
