feat: sdk 712 work manager support

itsdebs commented 6 months ago

Fixes # (issue)

What

Moved Work Manager to be a separate library. Configuration isPeriodicFlushEnabled needs to be true to turn on Work manager. Default time is 15 minutes. This is not configurable. (We can make this configurable based on discussion)

How to implement

Users need to implement sync library(Gradle details to be provided later)
Extend WorkManagerAnalyticsFactory class. This class instance will be created through reflection, hence it should have a default instance. This instance will provide an Analytics object. This is done to ensure that in case the work runs when Analytics instance has been garbage collected, we can create a new one through this factory.

class SampleWorkManagerAnalyticsFactory : WorkManagerAnalyticsFactory {
    override fun createAnalytics(application: Application): Analytics {
        return RudderAnalyticsUtils.createAnalyticsInstance(application)
    }
}

Extend WorkManagerPlugin class to provide the class name for the factory

class SampleWorkManagerPlugin: WorkerManagerPlugin() {
override val workManagerAnalyticsFactoryClassName: Class<out WorkManagerAnalyticsFactory>
    get() = SampleWorkManagerAnalyticsFactory::class.java
}

Create the Analytics instance

fun createAnalyticsInstance(application: Application): Analytics {
    return RudderAnalytics(
        writeKey = WRITE_KEY,
        initializationListener = { success, message ->
            // DIY
        },
        configuration = ConfigurationAndroid(
            application = application,
            GsonAdapter(),
            dataPlaneUrl = DATA_PLANE_URL,
            controlPlaneUrl = CONTROL_PLANE_URL,
            trackLifecycleEvents = true,
            recordScreenViews = true,
            isPeriodicFlushEnabled = true

        )
    )
}

Add the extended WorkManagerPlugin to Analytics as InfrastructurePlugin
```
analytics.addInfrastructurePlugin(SampleWorkManagerPlugin())
```

Why

A separate library will reduce complexity in main code.
Work manager features/bug fixes can be solved independently
Reduce code weight.
The factory to initialize Analytics is required since we don't want to store instance of Analytics from application as it might lead to memory leaks.
Reflection is necessary to initialize the factory as we can only pass in simple data to the Worker class.
