How can we integrate the IAV flow to add funding source in Android Apps? On the web side we are using Dwolla.js and we would like to use our own APIs which encapsulate the Dwolla APIs for integration.
I haven’t tried this with Android yet, but you should be able to include a WebView in your native application and use something like https://github.com/alinz/react-native-webview-bridge to communicate between your native app and the WebView.
Here is a related post you may find helpful:
An alternative could be to just load the WebView and have your native app and your server communicate. For example, the server could notify the app when the user has completed the IAV flow instead of the WebView notifying the native app.
Basically you will need to find a way to send a message from your WebView to your native code.
