This is part of a series of changes to minimize the number of spans committed to EditText, as a mitigation for platform issues on Samsung devices. See this [GitHub thread]( https://github.com/facebook/react-native/issues/35936#issuecomment-1411437789) for greater context on the platform behavior.
This change allows us to strip CustomStyleSpan. We already set all but `fontVariant` on the underlying EditText, so we just need to route that through as well.
Note that because this span is non-parcelable, it is seemingly not subject to the buggy behavior on Samsung devices of infinitely cloning the spans, but non-parcelable spans have different issues on the devices (they disappear), so moving `fontVariant` to the top-level makes sense here.

This change makes us apply strikethrough and underline as paint flags to the underlying EditText, instead of just the spans. We then opt ReactUnderlineSpan and ReactStrikethroughSpan into being strippable.
This does actually create visual behavior changes, where child text will inherit any underline or strikethrough of the root EditText (including if the child specifies `textDecorationLine: "none"`. The new behavior is consistent with both iOS and web though, so it seems like more of a bugfix than a regression.

We cache the backing EditText span on text change to later measure. To measure outside of a TextInput we need to restore any spans we removed. Spans may overlap, so base attributes should be behind everything else.
The logic here for dealing with precedence is incorrect, and we should instead accomplish this by twiddling with the `SPAN_PRIORITY` bits.

Because we've stripped the sizing spans, Spannable measurement has incorrect font size, and the TextInput size will change (collapsing) after the first edit. This effectively breaks any uncontrolled TextInput which does not have explicit dimensions set.

Pull Request resolved: https://github.com/facebook/react-native/pull/35967
In https://github.com/facebook/react-native/issues/35936 we observed that the presence of AbsoluteSizeSpan may lead to hangs when using the Grammarly keyboard on Samsung.
This mitigation makes it so that we do not emit this span in any case where it is sufficient to rely on already set EditText textSize. In simple cases, tested on two devices, it causes typing into the TextInput to no longer hang.
This does not fully resolve the issue for TextInputs which meaningfully use layout-effecting spans (or at least font size), such as non-uniform text size within the input. We instead just try to reduce to minimum AbsoluteSizeSpan possible.
Testing the first commit was able to resolve hangs in some simpler inputs tested, by me and cortinico.

Summary:
The current implementation of **getDefaultJSExecutorFactory** relies solely on try catch to load the correct .so file for jsc or hermes based on the project configuration.
Relying solely on try catch block and loading jsc even when project is using hermes can lead to launch time crashes especially in monorepo architectures and hybrid apps using both native android and react native.
So we can make use of an additional **ReactInstanceManager :: setJsEngineAsHermes** method that accepts a Boolean argument from the host app while building ReactInstanceManager which can tell which library to load at startup in **ReactInstanceManagerBuilder** which will now have an enhanced getDefaultJSExecutorFactory method that will combine the old logic with the new one to load the dso files.
The code snippet in **ReactInstanceManager** for adding a new setter method:
```
/**
* Sets the jsEngine as JSC or HERMES as per the setJsEngineAsHermes call
* Uses the enum {link JSInterpreter}
* param jsEngine
*/
private void setJSEngine(JSInterpreter jsEngine){
this.jsEngine = jsEngine;
}
/**
* Utility setter to set the required JSEngine as HERMES or JSC
* Defaults to OLD_LOGIC if not called by the host app
* param hermesEnabled
* hermesEnabled = true sets the JS Engine as HERMES and JSC otherwise
*/
public ReactInstanceManagerBuilder setJsEngineAsHermes(boolean hermesEnabled){
if(hermesEnabled){
setJSEngine(JSInterpreter.HERMES);
}
else{
setJSEngine(JSInterpreter.JSC);
}
return this;
}
```
The code snippet for the new logic in **ReactInstanceManagerBuilder**:
1) Setting up the new logic:
Adding a new enum class :
```
public enum JSInterpreter {
OLD_LOGIC,
JSC,
HERMES
}
```
A setter getting boolean value telling whether to use hermes or not and calling a private setter to update the enum variable.
```
/**
* Sets the jsEngine as JSC or HERMES as per the setJsEngineAsHermes call
* Uses the enum {link JSInterpreter}
* param jsEngine
*/
private void setJSEngine(JSInterpreter jsEngine){
this.jsEngine = jsEngine;
}
/**
* Utility setter to set the required JSEngine as HERMES or JSC
* Defaults to OLD_LOGIC if not called by the host app
* param hermesEnabled
* hermesEnabled = true sets the JS Engine as HERMES and JSC otherwise
*/
public ReactInstanceManagerBuilder setJsEngineAsHermes(boolean hermesEnabled){
if(hermesEnabled){
setJSEngine(JSInterpreter.HERMES);
}
else{
setJSEngine(JSInterpreter.JSC);
}
return this;
}
```
2) Modifying the getDefaultJSExecutorFactory method to incorporate the new logic with the old one:
```
private JavaScriptExecutorFactory getDefaultJSExecutorFactory(
String appName, String deviceName, Context applicationContext) {
// Relying solely on try catch block and loading jsc even when
// project is using hermes can lead to launch-time crashes especially in
// monorepo architectures and hybrid apps using both native android
// and react native.
// So we can use the value of enableHermes received by the constructor
// to decide which library to load at launch
// if nothing is specified, use old loading method
// else load the required engine
if (jsEngine == JSInterpreter.OLD_LOGIC) {
try {
// If JSC is included, use it as normal
initializeSoLoaderIfNecessary(applicationContext);
JSCExecutor.loadLibrary();
return new JSCExecutorFactory(appName, deviceName);
} catch (UnsatisfiedLinkError jscE) {
if (jscE.getMessage().contains("__cxa_bad_typeid")) {
throw jscE;
}
HermesExecutor.loadLibrary();
return new HermesExecutorFactory();
}
} else if (jsEngine == JSInterpreter.HERMES) {
HermesExecutor.loadLibrary();
return new HermesExecutorFactory();
} else {
JSCExecutor.loadLibrary();
return new JSCExecutorFactory(appName, deviceName);
}
}
```
### **Suggested changes in any Android App's MainApplication that extends ReactApplication to take advantage of this fix**
```
builder = ReactInstanceManager.builder()
.setApplication(this)
.setJsEngineAsHermes(BuildConfig.HERMES_ENABLED)
.setBundleAssetName("index.android.bundle")
.setJSMainModulePath("index")
```
where HERMES_ENABLED is a buildConfigField based on the enableHermes flag in build.gradle:
`def enableHermes = project.ext.react.get("enableHermes", true)
`
and then
```
defaultConfig{
if(enableHermes) {
buildConfigField("boolean", "HERMES_ENABLED", "true")
}
else{
buildConfigField("boolean", "HERMES_ENABLED", "false")
}
}
```
Our app was facing a similar issue as listed in this list: **https://github.com/facebook/react-native/issues?q=is%3Aissue+is%3Aopen+DSO**. Which was react-native trying to load jsc even when our project used hermes when a debug build was deployed on a device using android studio play button.
This change can possibly solve many of the issues listed in the list as it solved ours.

The testing for this change might be tricky but can be done by following the reproduction steps in the issues related to DSO loading here: https://github.com/facebook/react-native/issues?q=is%3Aissue+is%3Aopen+DSO
Generally, the app will not crash anymore on deploying debug using android studio if we are removing libjsc and its related libraries in **packagingOptions** in build.gradle and using hermes in the project.
It can be like:
```
packagingOptions {
if (enableHermes) {
exclude "**/libjsc*.so"
}
}

In https://github.com/facebook/react-native/pull/32695, the `Performance.now()` implementation changed to use unix epoch timestamps instead of a monotonic clock.
This is problematic, because it means that performance measurements get skewed if the device clock changes between two measurements.
With this change, the clock is now monotonic (and the implementation stays consistent between platforms).

Summary:
As per commit: https://github.com/facebook/react-native/commit/4f3b17412018a10f9293247c802598d2b94a844b which states that "React Native requires that the RootView id be managed entirely by React Native, and will crash in addRootView/startSurface if the native View id isn't set to NO_ID."
This behaviour can not be guaranteed in **hybrid** apps that have a native android layer over which ReactRootViews are added and the native views need to have ids on them in order to work. **The control of views can jump back and forth between native android and react-native (fabric). As the ReactRootView is added to ViewGroups (or layouts) in Android Fragments and Activities, they contain ids on their views which might get passed down to the reactRootView by features like DataBinding**
Hence this can cause unnecessary crashes at runtime for hybrid apps even when they are not changing the id of the reactRootView object they are adding to their ViewGroups.
Our app is a hybrid app that uses both native android and react-native on different screens and on one such screen that has a Fragment adding a ReactRootView to its FrameLayout to render native android views to render in ReactNative, this crash occurs on pressing the back button as well as on unlocking the screen while staying on the same screen.
The app was running fine on more than a 100 million devices on React Native 0.63.4 but after updating to 0.67.2, that features this commit, it crashes on the very first device it was tested on.
Refer to the issue: https://github.com/facebook/react-native/issues/33121 for more information on the crash
The fragment in which this issues arises is like this:
```binding.frameLayout.addView(getReactRootView())```
where getReactRootView() is like this:
```
private var mReactRootView: ReactRootView? = null
private var mReactInstanceManager: ReactInstanceManager? = null
mReactRootView = ReactRootView(context)
if (activity != null) {
val application = activity?.application
if (application is MainApplication) {
mReactInstanceManager = application.reactInstanceManager
}
}
fun getReactRootView():View?{
return mReactRootView
}
```
So converting this to a soft exception such that pure react-native devs can still see the error while hybrid apps continue to run without crashes.
### Snippet of the change:
```
if (getId() != View.NO_ID) {
ReactSoftExceptionLogger.logSoftException(
TAG,
new IllegalViewOperationException(
"Trying to attach a ReactRootView with an explicit id already set to ["
+ getId()
+ "]. React Native uses the id field to track react tags and will overwrite this"
+ " field. If that is fine, explicitly overwrite the id field to View.NO_ID."));
}
```

On Windows there are limits on number of character in file paths and in command lines
Ref: https://android.googlesource.com/platform/ndk/+/master/docs/BuildSystemMaintainers.md#Path-Length-Limits
NDK allows circumventing command line limits using response(RSP) files as inputs using NDK_APP_SHORT_COMMANDS flag.
Windows can support long file paths if configured through registry or by prefixing all file paths with a special character sequence
The latter requires changes in NDK. And there are tools in NDK (AR) which is not able to handle long paths (>256) even after setting the registry key.
The new architecutre source tree is too deep, and the object file naming conventions in NDK makes the matters worse, by producing incredibly long file paths.
Other solutions such as symlinking source code etc. didn't work as expected, and makes the build scripts complicated and hard to manage.
This change temporarily works around the issue by placing the temporary build outputs as short a path as possible within the project path.

Fixes a potential crash was introduced by https://github.com/facebook/react-native/issues/30919 that aimed to get the keyboard height on devices with a Notch. The problem is that it considers that any ReactRootView will have an insets available.
When using [react-native-navigation](https://github.com/wix/react-native-navigation) and assigning a Navigation button to the TopBar as a component, the component gets registered as a RootView but won't have any insets attach to the view.
[getRootWindowInsets()](https://developer.android.com/reference/android/view/View#getRootWindowInsets()) in fact return a `WindowInset` only available if the view is attached, so when executing `checkForKeyboardEvents` method from ReactRootView, is trying to access the `DisplayCutout` of a null object, leading to a crash.

Summary:
when migrated to `maven-publish` in https://github.com/facebook/react-native/issues/31611, the sources jar is not included by default from `maven-publish`. so react-native 0.66 / 0.67 doesn't include sources jar in npm published artifacts. it's not ideal for debug or tracing code.
this pr added the sources jar into the published artifact.
## Changelog
[Android] [Fixed] - Add missing sources jar into published android artifacts
Pull Request resolved: https://github.com/facebook/react-native/pull/32982
Test Plan:
make sure sources jar is included in artifact.
```
$ ./gradlew :ReactAndroid:installArchives
$ find android -name '*sources.jar*'
```

Summary:
The current JSLoader implementation (on Android) will copy the buffer into a JSBigBufferString during startup. This duplicates work Android is already doing (it allocates creates a copy of the bundle in memory while decompressing the asset from the APK) or worse, if the APK is mmap'ed this will unnecessarily create dirty memory.
The risk with this approach is that the bundle loaded from disk is no longer \0 terminated, but that's also the case for the bundles we load with `JSBigFileString` and is not an issue as far as I can tell.

Summary:
Per discussion in the previous diff D33672110, it's ok to add the `pointerEvents` prop to scrollview. This will help prevent scrolling on the ScrollView if pointerEvents is set to `box-none`, or `none`.
Corresponding doc changes are in https://github.com/facebook/react-native-website/pull/2936
Changelog:
[Android][Added] - Add new API in ScrollView and HorizontalScrollView to process pointerEvents prop.
