IIRC the Android OS requires the app to define which URL handlers it should be able to intercepts at compile time as a security measure so that an app can't decide to intercepts URL it shouldn't after being installed without your knowledge or consent.
The nature of the Fediverse makes it difficult to achieve that without hardcoding and maintaining a list of instances URLs in the app.
Only for external links opened through intents. Within the app, you are free to intercept all link opens.
Which is what OP is inquiring about, redirecting external links through intent (clicking link in a web browser and having them open in Jerboa).
That's not how I interpreted it - I understood it as OP being logged in through Jerboa, and then clicking a community link, and subsequently having it open in the web browser, in place of opening in Jerboa.
Jerboa is a native-android client for Lemmy, built using the native android framework, Jetpack Compose.
Warning: You can submit issues, but between Lemmy and lemmy-ui, I probably won't have too much time to work on them. Learn jetpack compose like I did if you want to help make this app better.
Jerboa is made by Lemmy's developers, and is free, open-source software, meaning no advertising, monetizing, or venture capital, ever. Your donations directly support full-time development of the project.
