Example Project in Github

For an example of how to use the Android SDK, please checkout our example project in Github:  

https://github.com/BlueTriangleMarketing/Blue-Triangle-SDK-Example

Supported Platforms

SDK for Android is available on the following platforms.

Gradle:

implementation 'com.bluetriangle:analytics:1.0.0'

Maven:

<dependency>
      <groupId>com.bluetriangle</groupId>
      <artifactId>analytics</artifactId>
      <version>1.0.0</version>
      <type>pom</type>
</dependency>

Ivy:

<dependency org="com.bluetriangle" name="analytics" rev="1.0.0">
      <artifact name="analytics" ext="pom"></artifact>
</dependency>

Building the AAR

To build the AAR library:

1. Open the BlueTriangleAndroidDemo project in Android Studio
2. Execute the assembleRelease task under the analytics Gradle project
3. The AAR should successfully build as seen in the Android Studio console
4. The generated AAR file should be found at analytics/build/outputs/aar/analytics-release.aar

Installing the AAR

1. Place the provided AAR analytics.aar in a libs directory in the app directory.
2. Add the libs directory to the app's Grade file list of repositories to find the analytics AAR.

repositories{
    flatDir{
        dirs 'libs'
    }
}

3. Add implementation(name:'analytics', ext:'aar') to your dependencies block in the app's Gradle file.

dependencies {
    implementation(name:'analytics', ext:'aar')
}

4. Sync the Gradle file changes.
5. Ensure <uses-permission android:name="android.permission.INTERNET"/> is configured in the application's AndroidManifest.xml.

Using the Analytics library

Initializing the Tracker

The Tracker is a singleton instance that is responsible for sending timers to Blue Triangle. Before any timers can be tracked, the Tracker needs to be initialized. The best place to do this in the Android Application. In the Application, the tracker can be initialized via the init static methods. If a site ID is not set during the initialization, it will attempt to look up the site ID via the application's String resources with a name btt_site_id as shown below. If a tracker URL is not provided, the default tracker URL will be used.

<string name="btt_site_id" translatable="false">BTT_SITE_ID</string>

// init with all defaults, use site ID in string resources file
Tracker.init(getApplicationContext());
// init with given site ID
Tracker.init(getApplicationContext(), "BTT_SITE_ID");
// init with given site ID and tracker URL
Tracker.init(getApplicationContext(), "BTT_SITE_ID", "https://webhook.site/5afd62e7-acde-4cf3-825c-c40c491b0714");

Using Timers

Timers are simple data objects that contain the associated times, fields related to the timer instance, and methods to start, mark interactive, and end a timer. Fields associated with the timer such as page name, traffic segment, brand value, etc can be set on the timer via convenience constructors and methods. Associated fields can be set anytime during the lifetime of the timer until submitted to the Tracker.

// create and start a timer
final Timer timer = new Timer("Page Name", "Traffic Segment Name").start();

// do work

// optionally, mark the timer as interactive
timer.interactive();

// maybe set a field
timer.setCartValue(99.99);

// do some more work

// end the timer and submit
timer.end().submit();

// or end the timer, set fields such as brand value, and finally submit the timer.

timer.end();
timer.setBrandValue(99.99);
timer.submit();

Timers implement Parcelable to allow timers to be passed via Bundle such as between activities in an Intent.

// MainActivity.java
final Timer timer = new Timer("Next Page", "Android Traffic").start();
final Intent intent = new Intent(this, NextActivity.class);
intent.putExtra(Timer.EXTRA_TIMER, timer);
startActivity(intent);

// NextActivity.java
final Timer timer = getIntent().getParcelableExtra(Timer.EXTRA_TIMER);
timer.end().submit();

When a timer is submitted to the tracker, the tracker sets any global fields such as site ID, session ID, and user ID. Additional global fields may be set as needed and applied to all timers. The timer's fields are then converted to JSON and sent via HTTP POST to the configured tracker URL.
