I am able to build my app Using Run in Android Studio, but using the React Native CLI which I prefer, the app will not build using the react-native run-android command.
Using the React Native CLI, I get the error message:
Execution failed for task ':app:packageDebug'.
> react_9eow0duexig9bim4oxa9fkqs2$_run_closure4$_closure6$_closure10$_closure18
There are plenty of online posts about referencing the first line of the error of which none of the solutions fix the build, but there are literally no google results when searching for the second line.
Why would Android Studio be able to build the app when the React Native CLI can't?
I'm using RN v 0.61.4
Any help much appreciated.

I am new to react-native or you can say new to React and I am working on react-native navigation I have installed all the required libraries as instructed in https://reactnavigation.org/docs/getting-started but when I am running my code it is giving an error as '#react-navigation/native could not be found within the project or in this directories.' What should I do is there any way to get started with my code? Help me
If you have installed your app following the react native cli guide you might want to try running
gradle clean
in your android folder und then try to run your app in the emulator again.
On my first steps with react native I stumpled upon the same issue. :-)
I was wondering if I could use Expo to run the react-native project that I created using the npx react-native init command, since it generates a better structure for real-world applications.
The reason I want to do this is to avoid the countless erros that I had while running and debugging the app.
You can't do that..
React native and expo are different.
You can run expo projects on react native by detaching them. Expo has limitations.
You can not run react native projects on expo, i.e projects made by react native init/npx can't run on expo
You can use a package made available by the expo
react-native-unimodules
for any React Native project using some resources made available by the expo.
react-native-unimodules
I developed a React Native application and tested it using Expo. When I finished, I tried to export the apk but I saw that it crash immediately after the execution. Then I tried to run "react-native run-android" and I see that the problem was something about Expo. The exact error is:
"The expo SDK requires Expo to run. It appears the native Expo modules are unavailable and this code is not running on Expo". How can I use this app without Expo? What should I do to make it work?
I am using expo for my react native application.
Steps:
- run expo start
Hit the error below on android studio emulator.
Working fine on real android device and IOS simulator.
UPDATE:
I have solved the issue. The issue was with my android studio. I open the app using the genymotion emulator and it was working
Unfortunately, Branch does not officially have a wrapper SDK for Expo and the link you referenced is built by a third-party which we cannot help troubleshoot.
Can you try ejecting your build from Expo and use native packages and linking in React Native, by following this: https://docs.branch.io/apps/react-native/#integrate-branch
I'm trying to use create-react-native-app as per the documentation with an example project that was built using instructions for react-native.
In terms of translating from one to the other what are the steps involved?
Edit: So i can run the app using npm start, with the expo.io QR code appearing as an option etc?
Create-react-native-app create a new project with Expo, you can eject it to turn it into a react-native project (android/ios folders with native code + src folder with javascript code).
You'll need an Xcode/Android Studio environment to run a react-native app built without Expo.
You can't use Expo to run a React-Native app with custom native code.
