Mobile Developer Resources

  • Integrate X-keys with your app
  • Use a communication channel independent of other input
  • No collision of programmed X-keys with Android standard features
  • Retain functionality of  on-screen keyboard

Method 1

Use our X-keys Android app to set up all keys on the X-keys as game controller buttons with values 17 and higher.  This prevents them from conflicting with keyboard, mouse, or game controller input from other input devices. Then incorporate a dispatchKeyEvent to "read" these buttons.  This is easy on Android and, unlike Windows, you get the sending device so you know it is an X-keys sending the button event.  See the free code samples: PIGameController and PIJoyKeys.

Method 2

Read and/or write X-keys USB HID data reports directly.  This method will allow the developer complete control over the indicator and backlighting LEDs.  See X-keys SDK for Android for free code samples for detecting and reading/writing the state of all controls and indicators.
