PayPalMessages Android Development Notes

Setup

Set Demo Client ID

Set the demo's client ID inside of demo locals

If you plan to make commits, be sure to ignore the file after you pull so you don't accidentally commit a client ID.

Ignored Files

To prevent commits of sensitive data, tell git to ignore future changes to some files, including:

Run ./scripts/ignore-files.sh -y, which will tell git to ignore the files above.

To see how to stop ignoring files or to list ignored files, see ignore-files.sh

Environment Variables

Add environment variables to your shell config file (~/.zshrc, ~/.bashrc, so on)

export UPSTREAM_ANDROID_STAGE_URL=""
export UPSTREAM_ANDROID_STAGE_VPN_URL=""
export UPSTREAM_ANDROID_LOCAL_URL=""

  1. Open your shell's Run Commands file (.zshrc, .bashrc, etc)
  2. Add a line to export JAVA_HOME and set its value to the path from step 3
export JAVA_HOME='/Applications/Android Studio.app/Contents/jbr/Contents/Home'

Or if it matches this path, you can run this command to add it your .zshrc

echo 'export JAVA_HOME="/Applications/Android Studio.app/Contents/jbr/Contents/Home"' >> ~/.zshrc
