Can't see stories on android emulator for react-native storybook

I'm building a mobile app with React Native and Storybook. But somehow, I can't see my component lists in the android emulator but can see my actual app screen.
ScreenShot
This is the screenshot of my android emulator and this is my actual app.

// Refer to https://github.com/storybookjs/react-native/tree/master/app/react-native#getstorybookui-options
// To find allowed options for getStorybookUI
const StorybookUIRoot = getStorybookUI({
// host: Platform.OS === "android" ? "10.0.2.2" : "0.0.0.0",

// If you are using React Native vanilla and after installation you don't see your app name here, write it manually.
// If you use Expo you should remove this line.
AppRegistry.registerComponent("%APP_NAME%", () => StorybookUIRoot);
export default StorybookUIRoot;
How do I start storybook
Run adb reverse tcp:7007 tcp:7007 (This is only once)
Start android emulator
Run yarn storybook
Run yarn android
Error log
No error log on metro server and the terminal that storybook running.

You need to import the storybook in your ./App.js:
import StorybookUIRoot from './storybook';
Now add the component to return in the App function:
return <StorybookUIRoot />

I had this issue for a few minutes until I realized I was running the command in the wrong directory...
I'm putting this here in hopes that this will help some future dev from making a similar, simple, mistake.

try npx react-native run-android

if "npx react-native run-android" is not working goto "package.jason" file
and look over "scripts" debugger is there.
clicking on debugger gives you options on top of the screen.
select"react-native run-android".

You have to update your npm version... Use this command and try again...
npm install npm#latest -g

how to import the eth-lightwallet package to the react-native project?

First, I created a project: react-native init project, and
when I try to import * as lightwallet from 'eth-lightwallet' in my react-native project, I get an error see this image
Found a solution at github, but this did not solve the problem for me.
My package.json:
{
"name": "androidWallet",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start",
"test": "jest"
},
"dependencies": {
"asn1": "^0.2.3",
"buffer": "^5.2.0",
"eth-lightwallet": "^3.0.1",
"history": "^4.7.2",
"native-base": "^2.7.2",
"node-libs-browser": "^2.1.0",
"node-libs-react-native": "^1.0.2",
"react": "16.4.1",
"react-native": "0.55.2",
"react-native-table-component": "^1.1.8",
"react-navigation": "^2.9.3",
"react-redux": "^5.0.7",
"react-router-dom": "^4.3.1",
"react-router-redux": "^4.0.8",
"redux": "^4.0.0",
"redux-logger": "^3.0.6",
"redux-thunk": "^2.3.0",
"web3": "^0.20.6"
},
"devDependencies": {
"babel-cli": "^6.26.0",
"babel-jest": "23.4.2",
"babel-preset-es2015": "^6.24.1",
"babel-preset-react-native": "4",
"jest": "23.4.2",
"react-test-renderer": "16.4.1"
},
"jest": {
"preset": "react-native"
}
}

The problem is that the eth-lightwallet depends on node core modules that isn't supported by React Native out of the box. The current workaround involves using
rn-nodeify in order to provide shims for React Native to use instead. See this issue for react native and see this open issue from eth-lightwallet.

Babel error when running ./gradlew assembleRelease

I receive this error after running ./gradlew assembleRelease:
Plugin/Preset files are not allowed to export objects, only functions.
In C:\..\node_modules\babel-preset-expo\index.js
:app:bundleReleaseJsAndAssets FAILED
**FAILURE: Build failed with an exception.**
This is what I have in package.json file:
{
"name": "Mascota24",
"version": "0.1.0",
"private": true,
"devDependencies": {
"babel-preset-stage-0": "^6.24.1",
"react-test-renderer": "16.3.1"
},
"scripts": {
"start": "react-native start",
"android": "react-native run-android",
"ios": "react-native run-ios",
"test": "jest"
},
"jest": {
"preset": "react-native"
},
"dependencies": {
"#babel/preset-react": "^7.0.0-beta.53",
"babel-preset-env": "^1.7.0",
"babel-preset-expo": "^4.0.0",

"react-navigation": "^2.6.2",
"react-redux": "^5.0.7",

}
And this is .babelrc file:
{
"presets": ["babel-preset-expo"],
"env": {
"development": {
"plugins": ["transform-react-jsx-source"]
}
}
}
I've followed almost every post here related with this and none of them helped me :( Thanks for any help

Thanks to #ashutosh pandey for the help, I changed react-native version to:
"react-native": "^0.55"
Then I installed redux and could generate the .apk! :D

is it possible to create a production build with react-native-mapbox-gl?

I have a location based app built with react-native and the react-native-mapbox-gl package (MapBox Maps SDK for React Native). The app runs on both Android and IOS devices with the commands react-native run-android and react-native run-ios respectively.
When i build a production release, the .ipa and .apk files are created successfully, but they fail to install on the devices
(without any specific error messages).
Is there some extra work that i need to do for building a production release with react-native-mapbox-gl?
this is my package.json
