Summary:
Changes React Native so that when `accessibilityState` is used to change a view from `selected: true` to `selected: false`, the change in state is announced.
This is how `checked` works; it is unclear why Android does not do this for `selected`, too.
Changelog:
[Android][Added] - TalkBack now announces "unselected" when changing `accessibilityState.selected` to false.

Summary:
This issue fixes https://github.com/facebook/react-native/issues/30955 and is a follow up to pr https://github.com/facebook/react-native/pull/24608 which added the basic Accessibility functionalities to React Native.
TextInput should announce "selected" to the user when screenreader focused.
The focus is moved to the TextInput by navigating with the screenreader to the TextInput.
This PR adds call to View#setSelected in BaseViewManager https://developer.android.com/reference/android/view/View#setSelected(boolean)
The View#setSelected method definition https://github.com/aosp-mirror/platform_frameworks_base/blob/master/core/java/android/view/View.java
```java
/**
* Changes the selection state of this view. A view can be selected or not.
* Note that selection is not the same as focus. Views are typically
* selected in the context of an AdapterView like ListView or GridView;
* the selected view is the view that is highlighted.
*
* param selected true if the view must be selected, false otherwise
*/
public void setSelected(boolean selected) {
if (((mPrivateFlags & PFLAG_SELECTED) != 0) != selected) {
// ... hidden logic
if (selected) {
sendAccessibilityEvent(AccessibilityEvent.TYPE_VIEW_SELECTED);
} // ... hidden logic
}
}

Summary:
Currently the react native framework doesn't handle the accessibility state changes of the focused item that happen not upon double tapping. Screen reader doesn't get notified when the state of the focused item changes in the background.
To fix this problem, post a layout change notification for every state changes on iOS.
On Android, send a click event whenever state "checked", "selected" or "disabled" changes. In the case that such states changes upon user's clicking, the duplicated click event will be skipped by Talkback.

Summary:
React Native components need a mechanism to specify their value to assistive technologies. This PR adds the notion of accessibilityValueDescription-- a property which either contains a textual description of a component's value, or for range-based components, such as sliders and progress bars, it contains range information (minimum, current, and maximum).
On iOS, the range-based info if present is converted into a percentage and added to the accessibilityValue property of the UIView. If text is present as part of the accessibilityValueDescription, it is used instead of the range-based information.
On Android, any range-based information in accessibilityValueDescription is exposed in the AccessibilityNodeInfo's RangeInfo. Text which is part of accessibilityValueDescription is appended to the content description.

Summary:
Our JS codegen assumes that all Android view managers extend `BaseViewManager` which allows generated delegates to set base view props using `BaseViewManagerDelegate`, see and example of the generated delegate for `FbReactTTRCStepRenderFlagManager`:
```
public class TTRCStepRenderFlagManagerDelegate<T extends View, U extends BaseViewManager<T, ? extends LayoutShadowNode> & TTRCStepRenderFlagManagerInterface<T>>{
public TTRCStepRenderFlagManagerDelegate(U viewManager) {
super(viewManager);
}
Override
public void setProperty(T view, String propName, Nullable Object value) {
switch (propName) {
case "traceId":
mViewManager.setTraceId(view, value == null ? null : (String) value);
break;
case "stepName":
mViewManager.setStepName(view, value == null ? null : (String) value);
break;
default:
super.setProperty(view, propName, value);
}
}
}
```
The problem is that `FbReactTTRCStepRenderFlagManager` doesn't extend `BaseViewManager`, but `ViewManager`, which means that we cannot use it with the generated delegate. We cannot use `ViewManager` instead of `BaseViewManager` in our JS codegen either, otherwise we will not be able to set base view props.
This diff makes it possible for delegates generated by JS to be used by Android view managers that do not extend `BaseViewManager`. By having a `BaseViewManagerInterface` we will be able to introduce a no-op base view manager implementation and wrap our original view manager in it so that we can pass as a constructor parameter to `BaseViewManagerDelegate`.
See an example of this approach for `FbReactTTRCStepRenderFlagManager`:
```
public class FbReactTTRCStepRenderFlagManager extends ViewManager<FbReactTTRCStepRenderFlag, ReactShadowNodeImpl> implements TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> {
private final ViewManagerDelegate<FbReactTTRCStepRenderFlag> mDelegate;
public FbReactTTRCStepRenderFlagManager() {
mDelegate = new TTRCStepRenderFlagManagerDelegate<>(new ViewManagerWrapper(this));
}
...
private static class ViewManagerWrapper extends BaseViewManagerAdapter<FbReactTTRCStepRenderFlag> implements TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> {
private final TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> mViewManager;
private FbReactTTRCStepRenderFlagManagerAdapter(TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> viewManager) {
mViewManager = viewManager;
}
Override
public void setTraceId(FbReactTTRCStepRenderFlag view, Nullable String traceId) {
mViewManager.setTraceId(view, traceId);
}
Override
public void setStepName(FbReactTTRCStepRenderFlag view, Nullable String stepName) {

Summary: Prior to Android P things like setScaleX() allowed passing float values that were bogus such as Float.NaN. If the app is targeting Android P or later then passing these values will result in an exception being thrown. Since JS might still send Float.NaN, we want to keep the code backward compatible and continue using the fallback value if an invalid float is passed. `sanitizeFloatPropertyValue` is an exact copy of the private method with the same name in `android.view.View.java`.

Summary:
This diff introduces an interface `ViewManagerDelegate` and its base implementation `BaseViewManagerDelegate`, which is used as a parent class for all view manager delegates generated by the JS codegen. Before the changes in this diff, generated delegates didn't support setting the base view properties such as background color, rotation, opacity, etc. Now it's possible to do by using `BaseViewManagerDelegate.setProperty(...)`, and since all generated delegates extend BaseViewManagerDelegate, they can just call `super.setProperty(...)` for properties they don't want to handle.
This diff also introduced a new method `ViewManager.getDelegate()`. This will allow view managers to return an instance of the delegate generated by JS and ensure that the view properties are set in a type-safe manner. If this method returns null (it does by default), we fall back to the default implementation of setting view properties using Java-generated `$$PropsSetter`
classes.
This is an example of an interface class generated by JS:
```
public interface RCTAxialGradientViewViewManagerInterface<T extends View> {
void setColors(T view, Nullable ReadableArray value);
void setLocations(T view, Nullable ReadableArray value);
void setEndX(T view, Float value);
void setEndY(T view, Float value);
void setStartX(T view, Float value);
void setStartY(T view, Float value);
}
```
This is an example of a delegate class generated by JS:
```
public class RCTAxialGradientViewManagerDelegate<T extends View, U extends BaseViewManager<T, ? extends LayoutShadowNode> & RCTAxialGradientViewManagerInterface<T>> extends BaseViewManagerDelegate<T, U> {
public RCTAxialGradientViewManagerDelegate(U viewManager) {
super(viewManager);
}
Override
public void setProperty(T view, String propName, Nullable Object value) {
switch (propName) {
case "colors":
mViewManager.setColors(view, (ReadableArray) value);
break;
case "locations":
mViewManager.setLocations(view, (ReadableArray) value);
break;
case "endX":
mViewManager.setEndX(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
case "endY":
mViewManager.setEndY(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
case "startX":
mViewManager.setStartX(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
case "startY":
mViewManager.setStartY(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
default:
super.setProperty(view, propName, value);
}
}
}
```
NOTE: What if a view manager, for instance ReactAxialGradientManager, wanted to add support for the borderRadius prop? In the old Java codegen, it would just need to create a method and annotate it with ReactProp (name = ViewProps.BORDER_RADIUS) and $$PropsSetter would call this method when a property with this name must be set. With the new JS codegen, borderRadius is a part of the basic view props, so setBorderRadius is not generated as a part of the ViewManagerInterface, so it’s not possible to set this value. I see two options: 1) add a method boolean setProperty (String propName, Object value) and let the view manager handle it in a non-type safe way (return true if it’s been handled). 2) Generate BaseViewManagerInterface which will include all basic view props and make BaseViewManager implement this interface, leaving all methods empty so that it stays compatible with the current implementation. Override these methods in a view manager that needs to handle a specific property in a custom way (so we would override setBorderRadius in ReactAxialGradientManager).

Summary:
Prior to this commit React Native on Android was not properly setting
the transform's scale properly correctly when setting it to 0. In order
to properly set one would need to use values close to 0, like 0.0001.
This was happing due to BaseViewManager sharing sMatrixDecompositionContext
across all views in a React Native app.
In some cases the decomposeMatrix() method from the MatrixMathHelper would
return early and not set any new values in sMatrixDecompositionContext
(this is, the new transform values) and
since this is a shared object the BaseViewManager would set the transform values
from the a previous transform.
In order to prevent this issue, before setting the new transform values
always reset the sMatrixDecompositionContext values.

Summary:
As currently defined, accessibilityStates is an array of strings, which represents the state of an object. The array of strings notion doesn't well encapsulate how various states are related, nor enforce any level of correctness.
This PR converts accessibilityStates to an object with a specific definition. So, rather than:
<View
...
accessibilityStates={['unchecked']}>
We have:
<View
accessibilityStates={{'checked': false}}>
And specifically define the checked state to either take a boolean or the "mixed" string (to represent mixed checkboxes).
We feel this API is easier to understand an implement, and provides better semantic definition of the states themselves, and how states are related to one another.

Summary:
In #24095, we removed the code that changes the underlying Android view's enabled state to false when "disabled" is included in the accessibility states, which seems correct. The Android view's state shouldn't mirror the accessibility state, it should be the other way round-- the accessibility state should represent the state of the view.
It seems that the existing test is brokenly setting the disabled state in the Javascript object, and then querying the Android view's enabled state to confirm the change. If the Button implementation is actually the culprit, then IMHO, the correct fix would be to have the Button implementation manipulate the Android View's enabled state, not the accessibilityStates code.

Summary:
React Native's minSdkVersion is 16, or we support Android versions 16 (Jelly Bean) and above. But in the code we have many checks if Android is Jelly Bean or newer, which are unnecessary. This PR removes unnecessary Android version checks, also uses Android version names instead of numbers.

Summary:
There is a variation in iOS and Android output while performing perspective transformation. The variation exists even when used in Android devices with different screen density.

Summary:
Accessibility roles are enums that are looked up by matching a string accessibility role from JS to the enum's name using .toUpperCase(). .toUpperCase() causes issues in certain languages such as Turkish because the "i"s translate to "?".
D9402330 tried to address this by forcing the .toUpperCase to use Locale.US, but now it sometimes translates to "?"
Use .equalsIgnoreCase() instead to avoid translations.

Summary: We were using a locale-specific `toUpperCase()` for accessibility roles. In the Turkish locale, `"image".toUpperCase()` does not become `"IMAGE"`; it becomes some weird turkish alphabet word, and we throw an error. This diff uses US-locale to avoid the error.

Summary:
Implemented a version of accessibility Hints on android by adding hint text to the end of contentDescription. There is already an existing prop on js and iOS implementation.
Changes involve:
* adding a prop on native android code for accessibilityHints
* setting the accessibilityDelegate after the props are all loaded.
* Instead of directly updating the accessibility delegate, the prop setters now update state by setting the values of the variables. Once all props are set, the accessibility delegate is set based on the props
* BaseViewManager keeps track of whether or not accessibility props have been set
* AccessibilityDelegateUtil keeps track of what the props have been set to. (Renamed AccessibilityRoleUtil to AccessibilityDelegateUtil)
Currently, this is the easiest way of emulating the way accessibility hints work on iOS, and I think having an android counter part is better than having nothing.
It's different from iOS in that it will announce the hint before the role, and also cannot be turned off.
Ex:
if I set the accessibility like this:
```
<View
style={styles.container}
accessible={true}
accessibilityLabel="accessibility label"
accessibilityRole="button"
accessibilityStates={['selected']}
accessibilityHint="accessibility Hint">
<Text> Tester </Text>
</View>
```
Talk back will read:
`accessibility label, accessibility Hint, button, selected`
In the future for next steps, I plan on investigating the process of making a second announcement after the first

Summary:
Added a check for null on `accessibilityStates`.
Now, if a null value is passed in to the prop, it simply does not do anything.

Summary:
Context:
After discussing with @[1038750002:yungsters], `currentViewStates` is a very ambiguous name for a prop, especially because there are only two possible values. From a developer's perspective, it makes more sense to just call them `accessibilityStates` because the main use for them is to add states to Talkback and Voiceover.
Defense for changing name in Android: The actual implementation of what we're changing under the hood in Native Code is abstracted away from developers using React Native, so as long as behavior is as they would expect, it makes more sense to change the name into a clear one regardless of how it is implemented.
Changes:
changed the Prop name from `currentViewStates` to `accessibilityStates` in the BaseViewManager file where the view property is being exposed.

Summary:
Added native android support for the prop accessibilityStates.
If 'selected' is passed in, it calls view.setSelected(true)
If 'disabled' is passed in, it calls view.setEnabled(false)
If both are passed in, both are set on the view.

Summary:
Added a new property to View for Accessibility called `accessibilityRole`. This property merges functionality of existing properties: `accessibilityTraits` (iOS) and `accessibilityComponentType` (android).
Currently, nine values are supported with equivalent behavior as `accessibilityTraits` (iOS) when `accessibilityRole` is set on iOS Voiceover and Android TalkBack
```
| 'none'
| 'button'
| 'link'
| 'search'
| 'image'
| 'keyboardkey'
| 'text'
| 'adjustable'
| 'tabbar'
```
They currently support similar behavior on talkback on Android and voice over on iOS
Does not break functionality of existing properties, but have not tested for behavior of setting both this one and the old one.
* iOS - I added a property accessibilityRoles, and basically remapped it to the same thing as accessibilityTraits. I also added in enum mappings for keyboardkey and tabbar.
* Android - Also added a property accessibilityRoles, from the Android side. For the underlying native functionality, I built a helper class that is based off of AccessibilityRolesUtil.java from the accessibility team. Biggest changes made are that I defined my own enums if needed, and also set some properties to match the functionality of iOS Accessibility Traits. I also handled the logic for switch/case statements of setting roles for the android side on this file. Also, I currently haven't localized strings for setRoleDescription, but plan to.
* Javascript - I added a view property accessibilityRoles in ViewPropTypes.

Summary:
If the z-index was updated after the initial mount, changes would not be reflected because we did not recalculate the z-index mapped child views and redraw the view. This adds code to do that and call it whenever we update z-index.
**Test plan**
Tested by reproducing the bug with 2 overlapping views that change z-index every second. Made sure it now works properly and z-index changes are reflected.

Summary:
This is the better fix for the same issue as mentioned in PR https://github.com/facebook/react-native/pull/14560
Certain rotateX, rotateY, scaleX and scaleY animations do not work correctly on some phones in Android 7.0.0, causing issues such as https://github.com/facebook/react-native/issues/14462 and https://github.com/facebook/react-native/issues/13522.
The issue can be fixed on JS side by setting an additional transform for perspective, eg. `{perspective: 1}` which triggers a `setCameraDistance` call in native code.
The fix in this PR always sets the camera distance on transforms, even when no perspective transform was specified. The default camera distance is set before the scale multiplication, to make sure that the value is appropriate for the phones density. The value calculates to an Android 'default' camera distance of 1280 * scale multiplier; https://developer.android.com/reference/android/view/View.html#setCameraDistance(float)
If a perspective transform is specified, this value will be used correctly still.
This fix was tested on the RNTester. Before the fix, on some devices, the FlatList example, with inverted turned on, will not display the list.
Devices that have been confirmed to have this issue:
FRD-AL10(honor 8) EMUI:5.0 android: 7.0
MHA-AL00(Mate9) EMUI:5.0 android:7.0
Huawei P10 VTR-L09, running Android 7.0
After the fix, the inverted FlatList displays correctly.
