React-Native run-android command issue

Posted by: admin May 14, 2020 Leave a comment


When starting android project with React-Native it is giving this error:

React-Native Command run-android unrecognized.Did you mean to run this inside a react-native project?

How to&Answers:

You can try to do npm install before react-native run-android


First we have to install react-native then upgrade packages if you need and run android.

npm install --save [email protected]

react-native upgrade

react-native run-android


A lot of developers fail to mention the crucial point,that certain commands require you to be a particular directory. In this case, to “react-native run-android”, you have to be in your project directory!


Command run-android unrecognized. Make sure that you have run npm install and that you are inside a react-native project.

I faced this issue, the problem is we need to navigate to or project folder.

example: I created the project in “MyApps” with app name “DemoApp” in D drive

the command line root should be like this:
D:\MyApps\DemoApp>react-native run-android

now it will run with out any issue.

The problem is your android related info is presents inside the app not t=in the main directory.


First of all please see if devices/emulator is attached and working by following command

adb devices

there should be some devices showing connected
it is better to restart/reconnect you emulator/device and then try to run application again
if not working you can also try

npm install 


I was facing the same problem and the above solutions did not work. Try using:

yarn add react-native-cli


In my case the problem was that I was in the android folder of my project due to this command cd android && ./gradlew assembleRelease.So the solution was to cd ../ and come to root of project and then running this command

react-native run-android --variant=release

ran fine.
