* To be on par with Apple TV support, this makes it possible to run React Native apps on Android TV devices (See also: https://react-native.canny.io/feature-requests/p/android-tv-support)
* These changes also make it possible to navigate through the app using D-PAD buttons that are present on some mobile devices
* Since these changes affect, among others, `ReactRootView.java` and `Touchable.js` code and are closely related to Apple TV implementation, it makes sense for them to be included in the core
- React native apps can be launched on Android TV devices and properly render their content
- Navigation is possible using left, right, top, bottom arrows from the remote (or D-PAD)
- Touchable components can handle D-PAD center button press events and correctly fire their `onPress` handlers
- Touchable components will receive `onPressIn` and `onPressOut` events and can react to focus/blur changes appropriately (just like on Apple TV)
- `Platform` constants allow to check if the react-native app is running on TV (`Platform.isTV`)
- `ScrollView`s behave correctly (same as native implementation) when switching to view outside bounds – that is, the container would scroll such that the newly focused element is fully visible
- Native "clicking" sounds are played when moving between focusable elements
- Play/Pause click event is send to `TVEventHandler`
- Rewind and FastForward events are send to `TVEventHandler`
- Back button behaves as a normal Android back button
- Diagonal buttons work correctly on Android TV, e.g. if there is no button directly to the right from the focused one, but there is one to the right but a bit higher/lower it will grab focus
- Dev menu can be accessed by long pressing fast forward button
A demo showing RNTester app running on Android TV device (Amazon Fire TV Stick) can be found here:

- `TextInput` will not work on Android TV devices. There's an issue with native `ReactEditText` implementation that prevents it from receiving focus. This makes it impossible to navigate to `TextInput`.
This will be fixed next, but will be included in a separate Pull Request
- ~Overlay permissions cannot be granted on Android TV devices running Android version >= 6.0
This is because the overlay permission can only be granted by firing an Intent to open settings page (`ACTION_MANAGE_OVERLAY_PERMISSION`). Since this page does not exist on TV devices the permission cannot be requested. This will make the app crash when trying to open dev menu (⌘+M) or displaying a redbox error.
Note: This does not affect devices running Android version < 6.0 (for example Amazon Fire TV Stick)~
This is now fixed by: https://github.com/facebook/react-native/pull/16596
* Launch the RNTester app on Android TV device.
* Ensure it launches without a crash
* Ensure basic navigation is possible
* Ensure Touchable components can receive select events
* Ensure the changes do not break current Android and iOS mobile devices functionality.
* Ensure the changes do not break current Apple TV functionality.

* Added `ReactAndroidTVViewManager` that handles TV `KeyEvent`s and dispatches events to JS - This is the core that enables basic navigation functionality on Android TV devices
* Following the above change we copy `TVEventHandler.ios.js` into `TVEventHandler.android.js` to enable JS to pick up those native navigation events and dispatch them further to subscribed views. (Note: We do not have a native `TVNavigationEventEmitter` implementation on Android, thus this file is slightly modified, e.g. it does pass `null` to `NativeEventEmitter` constructor)
* Added `uiMode` to `AndroidInfoModule`. (**Note**: This required changing `extends BaseJavaModule` to `extends ReactContextBaseJavaModule` to be able to use `getSystemService` which requires `Context` instance!
* Added `isTV` constants to both `Platform.ios.js` (keeping the deprecated `isTVOS` as well) and `Platform.android.js`
* Changed condition check on `Touchable.js` to use the newly added `isTV` flag to properly handle TV navigation events on Android as well
* Added `LEANBACK_LAUNCHER` to `RNTester` `intent-filter` so that it is possible to launch it on Android TV devices.
* See also a PR to `react-native-website` repo with updated docs for Android TV: https://github.com/facebook/react-native-website/pull/59
- [ ] Fix `TextInput` components handling by allowing them to be focused and making a proper navigation between them (and/or other components) possible. One thing to note here that the default behavior to immediately open software keyboard when focused on `TextInput` field will need to be adjusted on Android TV as well)
- [x] Fix overlay permissions issue by changing the way redbox/dev menu are displayed (see: https://github.com/facebook/react-native/pull/16596)
- [ ] Adjust placement of TV-related files (e.g. the `TVEventHandler.js` file is placed inside `AppleTV` directory which is not accurate, since it does handle Android TV events as well)
