Welcome to the Matomo Tracking SDK for Android. This library helps you send analytics data from Android apps to Matomo instances. Until v4 this library was known as Piwik Tracking SDK for Android.

Features:

• Caching and offline support
• Graceful reconnection handling
• WIFI-only mode
• Thread-safe support for multiple trackers
• Support for custom connection implementations
• Complete Matomo HTTP API support
  • Custom dimensions
  • Event Tracking
  • Content Tracking
  • Ecommerce
• Checksum based app install/upgrade tracking

For the not so quick start, see here or look at our demo app

• Setup Matomo on your server.
• Include the library in your app modules build.gradle file

    implementation 'org.matomo.sdk:tracker:<latest-version>'

• Now you need to initialize your Tracker. It's recommended to store it as singleton. You can extend MatomoApplication or create and store a Tracker instance yourself:

import org.matomo.sdk.TrackerBuilder;

public class YourApplication extends Application {
    private Tracker tracker;
    public synchronized Tracker getTracker() {
        if (tracker == null) tracker = TrackerBuilder.createDefault("http://domain.tld/matomo.php", 1);
        return tracker;
    }
}

• The TrackHelper class is the easiest way to submit events to your tracker:

// The `Tracker` instance from the previous step
Tracker tracker = ((MatomoApplication) getApplication()).getTracker();
// Track a screen view
TrackHelper.track().screen("/activity_main/activity_settings").title("Settings").with(tracker);
// Monitor your app installs
TrackHelper.track().download().with(tracker);
