Back and Home buttons pressed event for Android devices (cocos2d-x 3)

I have done this to catch

Home
and
Back
buttons press events on android devices:

Overrided
void Layer::onKeyReleased(EventKeyboard::KeyCode keyCode, Event* event)
function like this:

void MyLayer::onKeyReleased(EventKeyboard::KeyCode keyCode, Event* event)
{
if (keyCode == EventKeyboard::KeyCode::KEY_BACKSPACE /*KeyboardEvent::KeyCode::Menu(KEY_BACKSPACE)*/)
{
CCLOG("You pressed back button");
Director::getInstance()->end();
exit(0);
}
else if (keyCode == EventKeyboard::KeyCode::KEY_HOME)
{
CCLOG("You pressed home button");
// pause the game
}
}


also have called
setKeypadEnabled(true);
in
init
function of
MyLayer
. Backspace button closes the game on windows, but no reaction on Home button. Also on Android nothing happens when I press Home or Back. How to get this working on cocos2d-x 3.1?

Answer

For catching Back button you need to use EventKeyboard::KeyCode::KEY_ESCAPE. For pausing the game when Home is pressed use void AppDelegate::applicationDidEnterBackground(). There is no way to override home button pushed event.
