Getting Started

As you can see it is really simple to log with different analytics with a simple function:

val analytics = Raincoat<MyEvent>()
analytics.register(FirebaseProvider(context))
analytics.register(MixpanelProvider(context))
analytics.log(MyEvent.SignUp("username"))

Example

Using Kotlin sealed class we can easily setup all things that we will have to track:

sealed class MyEvent : EventType {

    class SignUp(username: String) : MyEvent()
    class Register(username: String, password: String) : MyEvent()

    override fun name(provider: ProviderType): String? {
        return when (this) {
            is SignUp -> "signUp"
            is Register -> "register"
        }
    }

    override fun parameters(provider: ProviderType): HashMap<String, Any>? {
        return when (this) {
            is SignUp -> {
                hashMapOf()
            }
            is Register -> {
                hashMapOf("username" to this.username, "password" to this.password))
            }
        }
    }
}

Providers

At this very moment we developed the following built-in providers:

• Firebase Analytics
• Flurry
• Localytics
• Mixpanel

In order to use them, you have to add to your project the library of the provider, otherwise the build will fail.

Custom Provider

You can easily create your own providers, you can use this for reference:

class MixpanelProvider(private val context: Context, private val projectToken: String) : ProviderType {

    override var className = Class.forName("com.mixpanel.android.mpmetrics.MixpanelAPI")
    override var classInstance = className.getDeclaredMethod("getInstance", Context::class.java, String::class.java)
    override var classFunction = className.getDeclaredMethod("track", String::class.java, JSONObject::class.java)

    init {
        classInstance?.let {
            // get context
            try {
                it.invoke(className, context, projectToken)
            } catch (e: Exception) {
                Log.e("Raincoat", e.localizedMessage)
            }
        }
    }

    override fun log(eventName: String, parameters: HashMap<String, Any>?) {
        try {
            classFunction.invoke(classInstance, eventName, JSONObject(parameters))
        } catch (e: Exception) {
            Log.e("Raincoat", e.localizedMessage)
        }
    }
}

Installation

Add to your build.gradle:

allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}
