Android (Kotlin)
Check out some examples of how to set up deeplinks and listen for webview redirects in Android 🤖.
Prerequisites
In order to be able to use the hosted widget in your Android app, make sure that you:
- Can create access_tokens in your server-side.
- Know how to implement webviews for your platform. For more information, see the webview articles from Google.
Set up deeplinks in your Android application
In your AndroidManifest.xml
file, add the following code:
<manifest ...>
<!-- ... -->
<application ...>
<activity ...>
<!-- ... -->
<intent-filter> <!-- You need to add this entire XML object. -->
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<!-- Accepts URIs that begin with belvowidget:// -->
<data
android:scheme="belvowidget"
android:host="" />
</intent-filter>
</activity>
</application>
</manifest>
Handle events in your webview
In the code sample below you can see an example of how to listen for and handle events within your webview.
val belvoWebView: WebView = findViewById(R.id. WEBVIEW_ID_ASSIGNED_IN_CONTENT )
belvoWebView.loadUrl("https://widget.belvo.io/?access_token={access_token_from_backend}")
belvoWebView.settings.javaScriptEnabled = true
belvoWebView.settings.allowContentAccess = true
belvoWebView.settings.setDomStorageEnabled(true)
belvoWebView.settings.useWideViewPort = true
belvoWebView.webViewClient = object : WebViewClient () {
override fun shouldOverrideUrlLoading(view: WebView?, url: String): Boolean {
view?.loadUrl(url)
if (url.startsWith("https")) {
return true
}
else {
belvoWebView.stopLoading()
val uri: Uri = Uri.parse(url)
val host: String? = uri.host
if (host == "success") {
val link : String? = uri.getQueryParameter("link")
val institution : String? = uri.getQueryParameter("institution")
// Do something with the link and institution.
}
else if (host == "exit") {
// If the redirect starts with "exit",
// Do something with the data.
}
else {
// If the redirect starts with "error",
// Do something with the data.
}
belvoWebView.goBack()
}
return false
}
}
Please note: You might receive a warning due to thebelvoWebView.settings.javaScriptEnabled = true
line (as in the image below). Belvo's Widget for Webviews fulfills all kinds of XSS mitigations, so we recommend suppressing this warning with the annotation suggested by Android Studio.
