Glorious isn't it? OK, not really. But it's cheap, simple & does work (and glory be, physical volume buttons!). You've prob seen these around & like most air mouse remotes, it takes some fiddling to make right. Here's how I did it.
First, be rooted. Its a must. Get the remote, plug in the USB dongle to the Shield & pair it as the instructions. Download ES File Explorer, enable root file browsing & give the /System RW access in the popup.
Go into Device (Root), System, usr, keylayout. In there you'll find a bunch of .kl files. These are what Android & Nvidia include to make certain controllers & remotes work correctly w specific keymaps & such. Creating a new one requires certain permissions & formatting I didn't wanna get into, so I elected to just modify an existing one I knew I'd never use. If you click on them & open as text, you can see what remote its for in the notes. So find one you don't care to lose. Do NOT alter the Generic.kl file & instead, choose one of the Vender ones (mine was one about a Wii controller). Edit it to make it look exactly like this. Also note the file name I have given it. That is specific to this remote model & it won't work without remaining it. Make your edits, save it & rename the file. Restart the Shield & you should be good to go.
All buttons will now function as they should & the air mouse still works too if you activate it. Note that the "back" button on this remote (and most air mouse types) isn't a back button at all, but a right mouse click (dumb). You can't remap that, so I made Back the Menu button right next to it. Also I could never get the keycode to the Home button because any app I'd try it with, pressing the key would exit the app before registering the code. If anyone knows a way please let me know. Regardless, you can get around this by side loading a simple app called Buttons Remapper. It sees the remaining Home button as a generic "0" key, but it will map it to the home function so it'll work perfectly after this.
Here is the exact one I bought, but there's a bunch of different versions floating around that may or may not have the same Vendor & Product numbers for the .kl file so be aware. Look up the ADB way of finding out these numbers via Terminal (its easy).
That's it. Enjoy your shitmote!
So, I found this: https://www.reddit.com/r/AndroidTV/comments/5zmm06/fyi_fire_tv_ncaa_march_madness_app_with_leanback/
But was wondering if any one has a more recent available apk that can be sideloaded to Android TV devices? Any help would be much appreciated. I have the mobile version and can cast from it but this is more for my wife while she is home during the day on maternity leave. We have PlayStation Vue so most games will be on there but we don't get our local CBS so I am trying to get all the games in one app for her.
If anyone is disappointed that TellyBean stopped supporting the camera directly connected to the Shield, apparently there is a new Android TV app, TrueConf, that supports them. Seems to work pretty well. Just had to lengthen the sleep timeout so the Shield wouldn't go to sleep while chatting. The app seems to have been around awhile, but just recently gained Android TV support.
