Description
I am trying too:
- Share
ReactInstanceManager
on Android for going from native views to React Native views - Use
createReactContextInBackground
to init the bridge and everything in advance so I don't get a long white screen the first time I access to a React Native view
Reproducible Demo
class MyApp : Application() {
lateinit var reactNativeHost: ReactNativeHost
override fun onCreate() {
super.onCreate()
reactNativeHost = RNExtendsReactNativeHost(this)
// Init the bridge and everything in advance
reactNativeHost.reactInstanceManager.createReactContextInBackground()
}
}
Then any of my activities that wants to load a React Native view:
reactInstanceManager = application.getReactNativeInstanceManager()
reactRootView = ReactRootView(this)
reactRootView.startReactApplication(reactInstanceManager, getModuleName(), properties)
setContentView(reactRootView)
Everything works great except that reactApplicationContext.currentActivity
is null only the first time.
- Open the app for the first time
- Click a button that loads a react native view
- In this point
reactApplicationContext.currentActivity
is null, so I cannot manage to callfinish()
from JS to go back to native - Using the hardware back button works
- Then I click again the button to go to the React Native screen and everything works because
reactApplicationContext.currentActivity
is not null
Nothing of this happens if I do not call createReactContextInBackground
. But then, loading a RN view for the first time is quite slow.
I am also not sure if this is a bug or is expected but I find it inconsistent.
