mouse right button mapped to work for traversing back in Jelly Bean

问题:

We have changed some part of code in `framework/base/services/input/inputreader.cpp to make the mouse right click work for traversing back.

case BTN_RIGHT:     mBtnRight = rawEvent->value;     break; 

to

case BTN_RIGHT:                            mBtnBack = rawEvent->value;     break; 

It is receiving all the mouse events.when I click the mouse right button it is receiving motion events as well as key events.But it is not able to dispatch key events.

Its giving error:

Is it a bug in Jelly Bean?

To make mouse Right_click to work as Back Button do the following changes. it is working for me.

 in function reset(InputDevice* device) {              replace mBtnRight = device->isKeyPressed(BTN_RIGHT); line to                      mBtnBack =  device->isKeyPressed(BTN_RIGHT);               and    in function process(const RawEvent* rawEvent) {                remove  3 lines   case BTN_RIGHT:                                 mBtnRight = rawEvent->value;                                 break;                      and Add "case BTN_RIGHT:" before case BTN_BACK:" as shown below                       case BTN_RIGHT:                      case BTN_BACK:                                             mBtnBack = rawEvent->value;                      break; 

/*Thats all it is working for me. */
