The game keyboard is capable of mapping the virtual keyboard of Android game to the entity (handle) key. After installing this software on the mobile phone, the virtual key position of the software is edited, so that the virtual keyboard button can produce the same effect as the virtual keyboard on the game virtual control key of the screen. Part of the reason for the need to install this software is that the game engineer does not develop the original ecological keyboard interface when developing the software, so it is necessary to download the game keyboard in the third party software to assist in mapping.
