React-native: android/gradlew Errors while starting the app with react-native run-android.

Created on 22 May 2017 · 3Comments · Source: facebook/react-native

Hi,

When I run react-native run-android I get the error message below.

I tried to track it and it's just when react-native calls Android/gradlew file which gives that error.

I'm using Android Emulator.

Error Message

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html

Also, I can wget https://services.gradle.org/distributions/gradle-2.14.1-all.zip and download the gradle-2.14.1-all.zip just fine.

Got it !! 👯‍♂️

In android/gradlew file I took a look and it's making use of JAVA_HOME environment variable that I did not have set.

Set it with steps from this SO link which solved my issue.

Solution code

export JAVA_HOME="/usr/lib/jvm/java-8-openjdk"
export PATH=$JAVA_HOME/bin:$PATH

save that to wherever you put your env vars
Eg .zshrc / .bashrc or scripts.sh files which can then get sourced
and viola!

Run react-native run-android does all the magic!

Thanks for this awesome project!
