Kotlin Deeplinking Solutions

Overview

Once the domain has been setup under the Open URL Mapping Editor within Android Studio, we need to set up the DeepLinkActivity class:

DeepLinkActivity.kt

package com.example.app
...

class DeepLinkActivity : ComponentActivity() {
    private fun handleIntent(intent: Intent?) {
        intent?.let {
            if (it.action == Intent.ACTION_VIEW) {
                val url = it.data.toString()
                fetchClickableLink(url)
            }
        }
    }

    override fun onNewIntent(intent: Intent?) {
        super.onNewIntent(intent)
        handleIntent(intent)
    }

    private fun fetchClickableLink(uri: String) {
        lifecycleScope.launch {
            val resolvedLink = withContext(Dispatchers.IO) {
                MIClient.resolveUrl(uri)
            }

            resolvedLink?.let {
                deepLinkToProductPage(it)
            }
        }
    }
}

An example where the resolved url is used to open content within the app:

private fun deepLinkToProductPage(url: String) {
    URIPath.getProductFromURI(url.toUri())?.let { productId ->
        val productDetailIntent = Intent(
            Intent.ACTION_VIEW,
            "${DeepLinkPattern.baseDestination}/$productId".toUri(),
            this@DeepLinkActivity,
            MainActivity::class.java
        ).apply {
            flags = Intent.FLAG_ACTIVITY_CLEAR_TOP or Intent.FLAG_ACTIVITY_SINGLE_TOP
        }

        try {
            startActivity(productDetailIntent)
        } catch (e: Exception) {
            Log.e(TAG, "Failed to send deep link pending intent", e)
        }
    }
}
