Summary:
We want to rename these types to be more clear what they are actually for. I did this with a find and replace:
```
import type {StyleProp} from 'StyleSheet';
```
to
```
import type {DangerouslyImpreciseStyleProp} from 'StyleSheet';
```
and `StyleProp` to `DangerouslyImpreciseStyleProp`.

Summary:
This type is being used in many places where a much simpler type is often better. In a real pinch this type can still be accessed as so:
```
function returnsStyleSheet(
): $Call<typeof StyleSheet.create, *> {
return StyleSheet.create({
root: {
background: 'white',
}
})
}
returnsStyleSheet().foo // foo doesn't exist
returnsStyleSheet().root // okay

* 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:
These types were polymorphic so that stricter types could be passed in for dimension or color. For example, color could be a union of allowed colors. However, since `rgb(0,0,0)` is a valid color, these would have to be allowed opaque types and every creator or caller of these colors would have to use a function.
This would require a massive change to every RN product in the world for negligable gain because StyleSheet values are validated at dev at runtime and cause redboxes for invalid uses.
Since we don't plan to adopt these widely, lets clean up the complexity of these types.

and then
```

The content of `TouchableOpacity` will still have opacity = 0.5 because real
opacity is controlled by animated property which should be properly updated

Usually when a button or other UI component is built with `TouchableOpacity` you may want to change it's opacity if state of component is changed (enabled/disabled). Opacity provided in props is overridden with internally-managed animated value. Add extra check when component is updated to trigger opacity animation upon change of `disabled` flag.
You can use code from https://github.com/facebook/react-native/issues/17105.
(If this PR adds or changes functionality, please take some time to update the docs at https://github.com/facebook/react-native-website, and link to your PR here.)

There is currently no way to disable to context menu that automatically appears over a TextInput. This is especially troublesome if you would like to disable the user from pasting text into certain fields. This PR adds a `contextMenuHidden` property to TextInput that will hide it.
I'm not sure if testing is necessary here. I would be happy to investigate further on how this would be tested, if deemed necessary!

Summary:
This is fixing #8615. The problem was that, on initialization, the `_connectionType` variable was still set to its default value of `RCTConnectionTypeUnknown`. The exposed API method did nothing to determine this unless a subscription had be established and then the method would simply return the last reported value. Instead, the exposed oneshot API call now actually checks the connection status through the same methods as the subscription and updates RCTNetInfo’s values before returning.
In order to avoid reporting events without a subscription, a flag is set and unset on calls to start/stopObserving.
- start app
- observe the (in)correct reporting of the manual status
- change network status to offline
- press refresh
- observe the manual fetch
- start subscription
- change network status to online
- press refresh to show that the manual refresh works (only now working for current RN version)
- change network status to offline
- stop subscription
- change network status to online
- press refresh to show manual refresh does(n't) work without subscription
- start subscription to show it updates to current

Summary:
When the `autogrow` prop was removed from `TextInput` on Android, the `_onLayout` helper method was removed. This helper method implemented the hook required to make `autogrow` work, then dispatched the `onLayout` event to the handler in `this.props`. This change points passes the `onLayout` handler from `this.props` directly to the inner component.

Summary:
WebSocket uses the Platform module to check how many arguments for the `close` method should be used. In react-native-windows, we have the same number of arguments for `close` as Android, so we're prevented from using this module as-is because of the platform check (see https://github.com/Microsoft/react-native-windows/blob/master/Libraries/WebSocket/WebSocket.windows.js#L136).
By switching to an argument count check, this module becomes more useful cross-platform. If you'd like to keep the platform check, I'm also open to inverting the conditional, e.g., `if (Platform.OS !== 'ios')`.

Most changes are removing trailing spaces from comments.
Haven't really done any manual testing, since I haven't done any code changes manually. `yarn test` runs fine, `yarn flow` runs fine, `yarn prettier` is satisfied.

Summary:
This PR adds support for Animated tracking to Animated Native Driver implementation on Android and iOS.
Animated tracking allows for animation to be started with a "dynamic" end value. Instead of passing a fixed number as end value we can pass a reference to another Animated.Value. Then when that value changes, the animation will be reconfigured to drive the animation to the new destination point. What is important is that animation will keep its state in the process of updating "toValue". That is if it is a spring animation and the end value changes while the previous animation still hasn't settled the new animation will start from the current position and will inherit current velocity. This makes end value transitions very smooth.
Animated tracking is available in JS implementation of Animated library but not in the native implementation. Therefore until now, it wasn't possible to utilize native driver when using animated tracking. Offloading animation from JS thread turns out to be crucial for gesture driven animations. This PR is a step forward towards feature parity between JS and native implementations of Animated.
Here is a link to example video that shows how tracking can be used to implement chat heads effect: https://twitter.com/kzzzf/status/958362032650244101
In addition this PR fixes an issue with frames animation driver on Android that because of rounding issues was taking one extra frame to start. Because of that change I had to update a number of Android unit tests that were relying on that behavior and running that one additional animation step prior to performing checks.
As a part of this PR I'm adding three unit tests for each of the platforms that verifies most important aspects of this implementation. Please refer to the code and look at the test cases top level comments to learn what they do.
I'm also adding a section to "Native Animated Example" screen in RNTester app that provides a test case for tracking. In the example we have blue square that fallows the red line drawn on screen. Line uses Animated.Value for it's position while square is connected via tracking spring animation to that value. So it is ought to follow the line. When user taps in the area surrounding the button new position for the red line is selected at random and the value updates. Then we can watch blue screen animate to that position.
You can also refer to this video that I use to demonstrate how tracking can be linked with native gesture events using react-native-gesture-handler lib: https://twitter.com/kzzzf/status/958362032650244101
[GENERAL][FEATURE][Native Animated] - Added support for animated tracking to native driver. Now you can use `useNativeDriver` flag with animations that track other Animated.Values
