My App on the Device that accessing my B4J Server. Many websites have a button where "open now in the app" or open the app automatically.
Would be nice if this happens as soon as I enter the URL of a handler.
Where is this "entering" happening? What exactly is the workflow that you are trying to accomplish? For example, maybe you're trying this:
Have an app on phone (one of your creation) talk to B4J server. Have server send URI to the phone app that the phone app then uses to start another app.
Or maybe you're trying to accomplish something else. What is the workflow?
The idea behind them is: User share a Post in my app with a link, if a other user is clicking on this link, then my app is starting and open this post via my app. Of course assumes that the app is installed, I will fix this later with a web version of my app.
Check the lib in my last post.
It does even work if your app is NOT installed (but available in playstore). The user will forwarded to install the app in playstore and then your app gets started giving the deeplink.
Basically you are defining a url which your app must be able to "understand".
And you dont need a server app at all for this.
