In-App Review API Integration in Jetpack Compose

#android #kotlin #googleplay #review

Google Play In-App Review API prompts users to rate your app without leaving. Higher completion rates than external reviews.

ReviewManager Setup

Initialize with Google Play Services:

val manager = ReviewManagerFactory.create(context)
val request = manager.requestReviewFlow()

request.addOnCompleteListener { task ->
    if (task.isSuccessful) {
        val reviewInfo = task.result
        val flow = manager.launchReviewFlow(activity, reviewInfo)

        flow.addOnCompleteListener {
            // Review submitted or dismissed
        }
    }
}

Compose Integration

Trigger after key user actions:

@Composable
fun TaskCompletionScreen(activity: FragmentActivity) {
    LaunchedEffect(Unit) {
        // Request review after task completion
        requestInAppReview(activity)
    }

    Column {
        Text("Task completed successfully!")
    }
}

suspend fun requestInAppReview(activity: FragmentActivity) {
    val manager = ReviewManagerFactory.create(activity)
    try {
        val reviewInfo = suspendCancellableCoroutine { continuation ->
            manager.requestReviewFlow().addOnCompleteListener { task ->
                if (task.isSuccessful) {
                    continuation.resume(task.result)
                } else {
                    continuation.resumeWithException(task.exception ?: Exception())
                }
            }
        }
        manager.launchReviewFlow(activity, reviewInfo)
    } catch (e: Exception) {
        Log.e("Review", "Failed", e)
    }
}

Smart Timing Strategies

Request at optimal moments:

After user completes key task (achievement, milestone)
3+ days since first install (not immediate)
When app is in foreground (not during background operations)
Max 3 times per app lifetime (across devices)

Avoid requesting:

During onboarding (user hasn't tried features)
During critical flows (payment, security setup)
On every app launch

Example timing check:

val sharedPrefs = context.getSharedPreferences("review", Context.MODE_PRIVATE)
val lastReviewTime = sharedPrefs.getLong("last_review", 0L)
val daysSinceLastReview = (System.currentTimeMillis() - lastReviewTime) / (24 * 60 * 60 * 1000)

if (daysSinceLastReview > 30) {
    requestInAppReview(activity)
    sharedPrefs.edit().putLong("last_review", System.currentTimeMillis()).apply()
}
