In this section, you will find how to implement the webview on Android for using the Unico IDPay product.

---

For the Android use case, using a Webview is recommended. After creating the transaction and obtaining the transaction link, the following implementation is recommended:

• In your regular flow (where IDPay is integrated), you will open the Webview with the link generated via API.

• You can customize how this opening works in the way that best fits your application.

• You will monitor if there is a URL change (to the redirectUrl) and then close the Webview.

Opening a Webview is quite simple:

import android.webkit.PermissionRequest
import android.webkit.WebChromeClient
import android.webkit.WebView
import android.webkit.WebViewClient

@SuppressLint("SetJavaScriptEnabled")
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_camera)

    findViewById<WebView>(R.id.webView).apply {
        settings.javaScriptEnabled = true
        settings.domStorageEnabled = true
        settings.mediaPlaybackRequiresUserGesture = false
        clearCache(true)
        webViewClient = myWebViewClient
        webChromeClient = object : WebChromeClient() {
            override fun onPermissionRequest(request: PermissionRequest?) {
                request?.grant(request.resources)
            }
        }
        loadUrl("<URL_TO_LOAD>")
    }
}

To control when it is necessary to close the Webview, it can be done as follows:

private val myWebViewClient = object : WebViewClient() {
    override fun shouldOverrideUrlLoading(
        view: WebView?,
        request: WebResourceRequest?
    ): Boolean {
        if (request?.url.toString() == "<URL_TO_OBSERVER>") {
            // close here your webview
        }
        return super.shouldOverrideUrlLoading(view, request)
    }
}

To do this, it is necessary to enable permissions in the Android Manifest:

<uses-feature android:name="android.hardware.camera" android:required="false"/>
<uses-permission android:name="android.permission.CAMERA"/>

Example of how it should look in the app:

It is necessary to have some permissions to function correctly, such as:

• Camera

• Geolocation
