How to launch an application from a browser on a mobile phone?

Question

Android

Is it possible, and if possible, how to make it so that on a site opened in any browser, when clicking on a link like "Our Vkontakte group", if the corresponding application is installed on the phone, this application with an open group is launched, and if the application is not installed then the group opened in the browser?

Answer 1

If the browser is yours, then you can launch anything when you click on the link, and if the browser is not yours, then you just have to use what third-party developers provide.
For example skype/number/email etc. there are special links for them mailto, skype:, tel: (I can be mistaken, this is just an example).
If the application is yours, then you can also do something similar to the one described above (read about Intent/IntentFilters)

Answer 2

from modern browsers you can open applications on the device,
though not from all, but they have a small percentage of popularity
here is a description of the technology

Answer 3

To do this, the Android application must support deep links:
developer.android.com/intl/ru/training/app-indexin... You
can also write a utility that will intercept links to "Our Vkontakte group" and try to push them into the desired application , but here you need to look at the source code to understand whether this is possible.
These are solutions from the category of perversions and are suitable only for personal use :).
