Stringboot includes a native A/B testing engine that allows you to test different string variations without changing your code.

​
How It Works

1

Assignment

The SDK generates a unique Device ID and assigns the user to an experiment variant (e.g., “Control”, “Variant A”).
2

Delivery

When you request a string (e.g., StringProvider.get("cta_button")), the SDK automatically returns the text for the assigned variant.
3

Tracking

You log the assignment to your analytics provider to track conversion.

​
Setup

No additional code is required to run the experiment. The SDK handles variant delivery automatically. To track the experiment, follow these steps:
1

Implement Analytics Handler

Create a class implementing StringbootAnalyticsHandler. Choose your analytics provider below:
class MyAnalyticsHandler : StringbootAnalyticsHandler {
    override fun onExperimentAssigned(assignment: ExperimentAssignment) {
        Firebase.analytics.logEvent("experiment_assigned") {
            param("experiment_key", assignment.experimentKey)
            param("variant_name", assignment.variantName)
            param("string_key", assignment.stringKey)
        }
    }

    override fun onExperimentViewed(experimentKey: String, variantName: String) {
        Firebase.analytics.logEvent("experiment_viewed") {
            param("experiment_key", experimentKey)
            param("variant_name", variantName)
        }
    }
}
2

Register Handler

Pass the handler during initialization:
StringProvider.initialize(
    context = this,
    cacheSize = 1000,
    analyticsHandler = MyAnalyticsHandler()
)

​
Debugging Experiments

You can check the current experiment assignments for debugging purposes: 
val experiments = StringProvider.getActiveExperiments()
experiments.forEach { exp ->
    Log.d("Stringboot", "Experiment: ${exp.experimentKey}, Variant: ${exp.variantName}")
}
