npx expo run:android

Expo Development Tools
1

Good morning, good afternoon and good night,
I would like to know what you need to have installed or configured on your computer to be able to execute this command: “npx expo run:android”
Since I get the following errors, that java, gradle, adb…

Could you give me a list or the requirements to run such a command and generate my development build?

Hi @wizardrevenge

Try the instructions here:

hi @wizardrevenge,
I am facing the same issue. Did you find a solution for it?

4

I was facing the same issue in my MAC and my Windows. I could not find any solution online. So I did the following to make it work and no idea if there is any incompatibility or surprise down the road or any other implications.

  • Remove current java version
  • Match up Gradle and Java version(Gradle 7.5.1 and Java 18)
  • Set Android sdk home environment variable(In windows gitbash, use bash style path i.e export ANDROID_HOME=/c/Users/[USERNAME]/AppData/Local/Android/Sdk)
  • run npx expo run:android
  • Forced to enjoy my sweet app

i tried. but still same error occur.

What are your java and gradle versions? Check out the mapping here: Compatibility Matrix

On Mac, you need to be careful as there are additional shell scripts steps.
