Copy and unzip the ti.newrelic-android-0.1.zip zipfile into your Titanium SDK directory. Typically this will be ~/Library/Application Support/Titanium or /Library/Application Support/Titanium.
Register the module with your application by editing tiapp.xml
and adding the module.
To start using New Relic, simply require the ti.newrelic module and call start with your app token:
require('ti.newrelic').start("YOUR_APP_TOKEN");
In a Titanium Alloy app, alloy.js is a perfect place to add this line of code.
In a Titanium Classic app, just add it to your app.js or wherever your app initialization happens.
