react-native: Could not install the app on the device, read the error above for details.

@RainliFu you might check the permissions on android/gradlew

they should be 755 not 644

run chmod 755 android/gradlew inside your app root folder then run react-native run-android

and it should work again.

how about windows i am getting the same error?

I’m running command as:

sudo react-native run-android

@cyprusglobe should this be put in documentation?

Thanks, it worked! good !

Basta modificar a permissão (sudo chmod -R 777 android/grandlew) da pasta android/grandlew dentro da raiz do projeto, ou você pode rodar o comando sudo react-native run-android…

I finally figured out the problem and solved it.

@cyprusglobe Thanks for your help. This pit is good!

I tried “sudo react-native run-android” on my mac, working fine!

I was facing same issue, I fixed by running “npm install” Lol

On windows, this can be resolved by reinstalling react-native-cli

npm uninstall -g react-native-cli

npm install -g react-native-cli

Restart powershell and Android Studio. You must start a new project and delete old ones.

react-native init NewProject

@eaintphyo ,can you share the experience! thanks!

@eaintphyo ,我想知道你是怎么解决的呀！？

if your android rom is MIUI ROM,find the solution: go settings -> developer option -> close MIUI optimization

Why there is still no solution for windows??

It helped on windows: Run ‘react-native run-android’ via cmd as admin
