According to https://libgdx.com/wiki/misc/adding-new-keycodes, the keycodes used by libGDX should be the same as in Android's KeyEvent class. However, this is not the case of the two Control (Ctrl) keys.
CONTROL_LEFT and CONTROL_RIGHT are defined as 129 and 130, respectively. However, Android's KeyEvent class uses different values. As we can see in https://developer.android.com/reference/android/view/KeyEvent, the values for KEYCODE_CTRL_LEFT and KEYCODE_CTRL_RIGHT are 113 and 114. For this reason, Gdx.input.isKeyPressed(Keys.CONTROL_LEFT) and Gdx.input.isKeyPressed(Keys.CONTROL_RIGHT) do not work correctly on Android, although these work correctly on desktop due to the method getGdxKeyCode() in the class DefaultLwjgl3Input.
Reproduction steps/code
A simple program that handles keyboard events by displaying the keycodes is enough. The problem can be noticed when connecting a USB keyboard to an Android phone (with the help of a USB to USB Mini adapter if necessary) and pressing any of the two Ctrl keys. The displayed keycodes will be different depending on whether the program is running on Android or desktop.
