question

I have a MOGA Pro Bluetooth HID controller that I've implemented in a game. This works on other Android-based, non-Amazon products like the Motorola Xoom and Nexus 7. Connecting it to the Kindle Fire HD and Kindle Fire HDX (via Mode "B" / aka 'Bluetooth HID' mode) gives me slightly different behavior. If nothing else, I'd just like to share what I've run into. Observations: - The MOGA Pro is recognized and can connect just fine to both Kindle Fire HD and Kindle Fire HDX. I can use the Dpad and Joystick to navigate through the Kindle menus correctly. That's great! - Using the 'B' button to 'go previous screen' works as expected. - Accept button handling is slightly different than on other Android based devices. Other devices use the 'A' button to launch a highlighted app. On the Kindle Fire HDX, it's the 'X' button that launches a highlighted app. No big deal. - Pressing the START button and then releasing it acts as if the HOME button is pressed. In other words, it escapes from the currently running app and brings you back to the app launcher menu on the Kindle. On the Nexus 7 and Motorola Xoom, this behavior does not occur. This is a sticking point for me because I don't have much control over what the OS is doing. In my game, when you press down on START the in-game menu pops up and then when you let go of the START button, you are put back on the app launcher screen. I also have an NVIDIA Shield which has a built-in gamepad controller. Its buttons behave in the same manner as the Motorola Xoom and Nexus 7 w/ a connected MOGA Pro. I realize that there is no Android Gamepad standard (or if there is one, I'm unaware of it). I just thought I'd point out the differences that I've run into with getting my game ready for the Amazon App Store. Thanks, --tim
