Application has not been registered (react-native-navigation v2) - wix-react-native-navigation

Question

React native navigation v2 issue.
My app starts with index.js and it is registered into AppDelegate as well. Here is the details:
import { AppRegistry } from 'react-native';
const { start } = require('./src/app');
start();
Here app.js:
```
const { Navigation } = require('react-native-navigation');
const { registerScreens } = require('./screens');
const { Platform } = require('react-native');
if (Platform.OS === 'android') {
alert = (title) => {
Navigation.showOverlay({
component: {
name: 'navigation.playground.alert',
passProps: {
title
},
options: {
overlay: {
interceptTouchOutside: true
}
}
}
});
};
}
function start() {
registerScreens();
Navigation.events().registerAppLaunchedListener(() => {
Navigation.setDefaultOptions({
_animations: {
startApp: {
y: {

to: 0,
duration: 500,
interpolation: 'accelerate',
},
alpha: {

}
},

topBar: {

}

interpolation: 'decelerate',
},
alpha: {
from: 1,
to: 0,
duration: 500,
interpolation: 'decelerate'
}
}
}
}
});
Navigation.setRoot({
root: {
stack: {
id: 'TEST',
children: [
{
component: {
name: 'rp.welcome'
}
}
]
}
}
});
});
}
module.exports = {
start
};
Screen Registrations:
const { Navigation } = require('react-native-navigation');
const WelcomeScreen = require('./WelcomeScreen');
const Authentication = require('./Authentication').default;
const Tutorial = require('./Tutorial');
function registerScreens() {
Navigation.registerComponent(`rp.welcome`, () => WelcomeScreen);
Navigation.registerComponent(`rp.tutorial`, ()=>Tutorial);
Navigation.registerComponent(`rp.authentication.super`,()=> Authentication);
}
module.exports = {
registerScreens
};

I had a similar issue in V2, and the problem was caused by not removing the rootView settings in the didFinishLaunchingWithOptions methods in AppDelegate.m.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSURL *jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:#"index" fallbackResource:nil];
[ReactNativeNavigation bootstrap:jsCodeLocation launchOptions:launchOptions];
RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
moduleName:#"XXXXXXXXXX"
initialProperties:nil
launchOptions:launchOptions];
rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
UIViewController *rootViewController = [UIViewController new];
rootViewController.view = rootView;
self.window.rootViewController = rootViewController;
[self.window makeKeyAndVisible];
return YES;
}
If you leave them in, It will cause the Application XXXXXXXXXX has not been registered error. The IOS instructions in https://wix.github.io/react-native-navigation/v2/#/docs/Installing should stress that these rootView related lines must be removed.
The correct AppDelegates.m should be like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSURL *jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:#"index" fallbackResource:nil];
[ReactNativeNavigation bootstrap:jsCodeLocation launchOptions:launchOptions];
return YES;
}

I had the same issue but only on Android. It turned out I had missed a step in the configuration process.
In MainActivity.java it should extend com.reactnativenavigation.NavigationActivity instead of ReactActivity.

I have solved this by putting the string name of the component like this:
instead of: component: YourComponent
it should be:
component: {
name: 'YourComponent'
}
complete code below:
Navigation.events().registerAppLaunchedListener(() => {
Navigation.setRoot({
root: {
stack: {
children: [
{
component: {
name: 'YourComponent'
}
}
]
}
}
})
});
also, if you push or setStackRoot, you should always use component name:
e.g.
component: {
name: 'YourComponent'
}
