Launch custom Android application from WebView

Issue

I have an HTML file which is launching an app if I open it in the Android native browser, but when I try to open the same in a WebView, it is not able to launch that application, and "Webpage not available" is shown. I think my WebView is not able to handle the scheme "my.special.scheme://" defined for the application.

I read Launching an Android Application from the Browser, but it does not cover information about launching an app from a WebView.

Solution

I'm not sure, but I believe that WebView simply doesn't handle custom URI schemes.

The workaround is to override WebViewClient.shouldOverrideUrlLoading() and manually test if the URL uses your URI scheme, launching your app and returning true if it matches, otherwise returning false.
