# If you get "emulator command not found" error, please see troubleshooting section below

Customization

To customize the build, create a .env. The following variables are supported:

  • MORDOR_INDEXER_URL, MORDOR_NODE_URL: Mordor testnet URLs.
  • ROPSTEN_INDEXER_URL, ROPSTEN_NODE_URL: Ropsten testnet URLs.

Sentry setup

cp sentry.properties.example ios/sentry.properties
cp sentry.properties.example android/sentry.properties

Then add your keys into both files.

Troubleshooting

iOS

  • If you're using nvm and you get the error

Command PhaseScriptExecution failed with a nonzero exit code

Make sure you've run the commands for Sentry setup above ☝️ - you will also need to complete those sentry.properties with a real sentry config.

If the issue persist, check this issue facebook/react-native#31181 - you might need to set an alias for default

# replace "lts/erbium" with the appropiate lts version listed in nvm list
nvm alias "default" "lts/fermium"

If you get the error

env: node: No such file or directory

You might need to link your nvm with your usrl local.

Try

sudo ln -s "$(which node)" /usr/local/bin/node

As stated in this answer

  • If you get the error error: SDK "iphoneos" cannot be located when running npm ci, run the following commmand:
sudo xcode-select --switch /Applications/Xcode.app

and run npm ci again

Android

  • If you don't have an emulator installed, after installing Android Studio, set the following env variables:
# Android emulator path
export ANDROID_SDK=$HOME/Library/Android/sdk
export PATH=$ANDROID_SDK/emulator:$ANDROID_SDK/tools:$PATH
export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
# jdk path - update accordingly with your jdk path
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_291.jdk/Contents/Home

You will have to download the Jdk version (1.8 at minimum) - and set the JAVA_HOME.
You can follow the documentation to add a new device.
