Add analytics to Android (Kotlin) Android (Kotlin).

object Analytics {

    val payload = JSONObject(mapOf(
      "name" to name, "distinct_id" to distinctId, "properties" to JSONObject(properties)))
    val req = Request.Builder().url("$host/v1/events")
      .addHeader("Authorization", "Bearer $key")
      .post(payload.toString().toRequestBody(json)).build()
    client.newCall(req).enqueue(object : Callback {
      override fun onFailure(call: Call, e: java.io.IOException) {}

// batch: POST a JSON array to /v1/events to cut requests

No native SDK. Uses OkHttp, standard on Android, and enqueue keeps it off the main thread. Call track from onResume or your nav destination listener.

Call track() from a lifecycle onResume or a Navigation OnDestinationChangedListener so each screen logs a screen_view with the destination in properties, and fire it on the taps that matter (signup, checkout, share). Pass a stable distinct_id, the user id after login or an install id before, so funnels and retention collapse to one real person.

Mobile radios love fewer wakeups, so batch. Buffer events in a list and flush a single JSON-array POST to /v1/events on an interval or in onStop when the app backgrounds. Same endpoint and write key as your web and backend, so it all lands together and you can just ask, in plain English, where users drop off, backed by a report that a CI test proves cannot be hallucinated.

Honest pricing: 14-day full trial, no credit card. Then Solo $29/mo, never metered on seats or sites. Overage is $5/million with an emailed receipt, the dashboard never locks, and self-hosting the single Go binary is free forever (MIT).
