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.

Test Plan:
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"
}
}
```

Summary:
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:
Currently, we build Hermes by specifying the Cmake flag `-B ./hermes`. That means
that the output out the build is going to be placed along side the source code.
This is fine, as long as the user doesn't use the `REACT_NATIVE_OVERRIDE_HERMES_DIR`,
which is used inside the Hermes CI. In that case, the source location of Hermes can be
changed, leading to scenarios where `hermesc` can't be found.
Here I'm changing the flag to be `-B $buildDir/hermes`. Therefore the build output
will always be located within the `./ReactAndroid/hermes-engine/build` folder.
This is a more robust solution as the build output will be encapsulated within the
`build/` folder.

D34687371 (https://github.com/facebook/react-native/commit/7b5b114d578142d18bf4a7a5279b179a9ac8d958) unfortunately caused a regression with UIAutomator, where it would no longer be able to see any Views that have the ReactAccessibilityDelegate attached to them. This was because the delegate was changed to extend ExploreByTouchHelper which implements its own default AccessibilityNodeProvider, which does nothing in the case of a view without any virtual children.
This diff simply *only* uses the node provider if the view in question has virtual children, otherwise defaulting to the standard behavior from the View class.
Changelog:
[Android][Fixed] - Fixed issue where any node with an AccessibilityDelegate set (which was any node with any accessibility propoerty), was using ExploreByTouchHelper's built in AccessibilityNodeProvider, and not properly populating their AccessibilityNodeInfo's, leading to focus issues and issues with automated test services like UIAutomator.

[Android][Fixed] - Fix Extras usage in Android implementation of Linking.sendIntent()
The implementation of sendIntent() has a bug in a way it uses extras map.
From JS layer the API sends and array of map, where each map contains exactly 2 entries: {"key" -> "name_of_extra_to_use", "value" -> value_of_extra_to_use}
However Java parsing was just picking a random pair out of this map and was sending it as extra.
Most frequently the result was "value" -> value_of_extra_to_use in Intent instead of name_of_extra_to_use -> value_of_extra_to_use

`rootProject` should never be used directly as it resolves to:
- The root of the git repo of `react-native` when building the RN project (so
`./ReactCommon` exists there).
- The /android folder of users' project when building an app that uses RN (so
`./ReactCommon` does not exists there).
