Nullkeyboard/0Keyboard or empty Keyboard (what ever you want to call it) adds an extra keyboard to your device, which will not show when selecting text fields.It is intended to be used with hardware keyboards (i.e. bluetooth keyboards), to stop the software keyboard from opening and taking away half of the screen. Additionally it improves system performance as it frees up resources that would normaly be used by a software keyboard (layout, dictionarys etc.).This app is a 'must-have' for people who regularly use an extra keyboard with their android tablet. While they cannot uninstall the system keyboards, they can unload them from system memory bychoosing Null Keyboard as current keyboard.A widget is included to allow easy switching between Null Keyboard and others.This is not a driver and will not make your bluetooth keyboard work and neither will it break anything. Don't complain that it doesnt make your bluetooth keyboard work, because that is not itspurpose.
