Summary:
This PR fixes a bug in `deepFreezeAndThrowOnMutationInDev` which did not take into account that objects passed to it may have been created with `Object.create(null)` and thus may not have a prototype. Such objects don't have the methods `hasOwnProperty`, `__defineGetter__`, or `__defineSetter__` on the instance.
I ran into an unrecoverable error in React Native when passing this type of object across the bridge because `deepFreezeAndThrowOnMutationInDev` attempts to call `object.hasOwnProperty(key)`, `object.__defineGetter__` and `object__defineSetter__` on objects passed to it. But my object instance does not have these prototype methods.
Changes:
* Defined `Object.prototype.hasOwnProperty` as a `const` (pattern used elsewhere in React Native)
* Modified calls to `object.hasOwnProperty(key)` to use `hasOwnProperty.call(object, key)` (Per ESLint rule [here](https://eslint.org/docs/rules/no-prototype-builtins))
* Modified calls to deprecated methods `object.__defineGetter__` and `object.__defineSetter__` to instead use `Object.defineProperty` to define get and set methods on the object. (Per guidance on [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/__defineGetter__))
* Added a new test to `deepFreezeAndThrowOnMutationInDev-test` to verify the fix.
I tried to create a reproducible example to post to Snack by passing prototype-less objects to a `Text` component, in various ways, but they appear to be converted to plain objects before crossing the bridge and therefore they do not throw an error.
However, I was able to create a new test to reproduce the issue. I added the following test to `deepFreezeAndThrowOnMutationInDev-test`:
```JavaScript
it('should not throw on object without prototype', () => {
__DEV__ = true;
var o = Object.create(null);
o.key = 'Value';
expect(() => deepFreezeAndThrowOnMutationInDev(o)).not.toThrow();
});
```
The changes in this PR include this new test.
ESLint test produced no change in Error count (3) or Warnings (671)

Summary:
This PR removes the need for having the `providesModule` tags in all the modules in the repository.
It configures Flow, Jest and Metro to get the module names from the filenames (`Libraries/Animated/src/nodes/AnimatedInterpolation.js` => `AnimatedInterpolation`)
* Checked the Flow configuration by running flow on the project root (no errors):
```
yarn flow
```
* Checked the Jest configuration by running the tests with a clean cache:
```
yarn jest --clearCache && yarn test
```
* Checked the Metro configuration by starting the server with a clean cache and requesting some bundles:
```
yarn run start --reset-cache

* 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:
[](http://www.youtube.com/watch?v=EzIQErHhY20)
- `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.
[RNAndroidTVDemo video](http://img.youtube.com/vi/EzIQErHhY20/0.jpg)
* 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)

Summary:
The code to display HMR errors on the client was reading the `description` field from Metro payloads. Metro does not include `description` in the body of its error payloads -- only in its `body.errors[]` items. This commit changes RN's HMR code to show `body.message` (set consistently with https://github.com/facebook/metro/pull/124) instead of the non-existent `body.description`.
Open a test RN app, enable HMR, and then introduce a syntax error in an app source file. See that the redbox provides information about the syntax error instead of just saying "TransformError undefined".

Summary:
This usage of `...` currently causes BackHandler to silently become non-functional when a `Symbol` polyfill is used.
Why?
- The `[...obj]` operator implicitly calls the object's iterator to fill the array
- react-native's internal `Set` polyfill has a load order issue that breaks it whenever a project uses a `Symbol` polyfill
- This means that when `BackHandler` tries to `[...set]` a `Set` of subscriptions the result is always an empty array instead of an array of subscriptions
Additionally it's worth noting that the current code is also wastefully inefficient as in order to reverse iterate over subscriptions it:
- Clones the `Set` (which fills it by implicitly running the set's iterator)
- Uses `[...set]` to convert the cloned set into an array (which also implicitly runs the iterator on the clone)
- Finally reverses the order of the array
----
This code fixes this problem by replacing the use of multiple Set instance iterators with a simple `.forEach` loop that unshifts directly into the final array.
I've tested this by opening the repo's RNTester app on Android and tvOS ensuring that the back handler works before changes, the application crashes when I introduce an error (to verify my code changes are being applied to the app), the back handler works and after changes.
