Kudos for this rare video. There are many issues to face: upgrading to a higher React Native version, when Apple deprecates a version of IOS, 3rd party libraries not upgraded to a new react version or incompatible to a higher verion of ios or android

[@pademo57]

Absolutely love these videos. Finally someone who explains not only what is the best way to set this up but also what to look for or what to do when something goes wrong. Thank you and keep up the good work!

[@HiteshCodeLab]

Glad it was helpful!

[@shivtiwarii]

to those who are facing the issue with the final command that starts the preview on the device, try running "npm run start" in a separate terminal and then in another terminal run "npm run android"

[@samarththaker5051]

Thank you vey much. I could not figure out what to do.

[@mehdi2368]

for people who are facing problems setuping env i recommend you to start with expo and then after you learn react native you can solve your previous problems

[@relks8429]

For everyone that is having problems, do not use expo go under any circunstancies. It will bring you lot of more problems.

[@NOT_TON_Fan]

React Native environment setup is damn difficult but finally I've done it in 2 hrs. Most of the issues were solved by setting the env variable.

[@HiteshCodeLab]

It’s definitely worth it

[@surajmaurya1515]

Can you Help me ? PLease

[@vivekkushwaha9334]

Thanks, I have been struggling with the same error over more than two weeks.

After long time I am waiting for your video for react native thank u

[@guddubhaiyathikanamirzapur4079]

Your videos are easily understandable...Even if I have to pay something for these kinds of lectures, I will happily do it.

[@kazitanim007]

FYI: run "npm" instead of "npx" and hopefully there will be no issues if all the settings are fine. - npm start - npm run android

[@oseifrimpongg]

I just love the constant reassurances. I hope I am able to make it to the end of the series 😄!

[@10bhavankumarv47]

Hi sir great video 👏 BTW, when I run "adb devices" it's not listing any devices. Also could you please explain how to mirror the output on our phone more elaborately on the next episode? Thanks in advance 😉

[@sumitram4132]

It's takes 3 months to setup using CLI process but finally did it.

[@rehandev7833]

After facing my first error in getting the Metro Server up and running, really excited to start writing code in React Native. Moving onto the next video :)

a note for those who build nowadays run npm start first and then run in another terminal npm run android and if there is a error then make a fresh install of android studio and jdk (i got issue with that)

[@frankbuzzz]

Hello Sir, When I continue using my app the app runs fine but when I don't use it for more than 5 minutes it slows down for a minute and then it seems to be running normally as before. I made my app react native. While its backend code is written in codeignitor4, the data from PHP and API is being fetched at the right time for viewing from postman, what is the problem, why is my app getting slow.

[@elamandeep]

In Linux, React native setup is quite easy. I too faced one error while running npx react-native init command but it was easy fix😁😁
