Say I want to define that an URI such as:
myapp://path/to/what/i/want?d=This%20is%20a%20test
must be handled by my own application, or service. Notice that the scheme is "myapp"
and not "http"
, or "ftp"
. That is precisely what I intend: to define my own URI schema globally for the Android OS. Is this possible?
This is somewhat analogous to what some programs already do on, e.g., Windows systems, such as Skype (skype://
) or any torrent downloader program (torrent://
).

As the question is asked years ago, and Android is evolved a lot on this URI scheme.
From original URI scheme, to deep link, and now Android App Links.
Android now recommends to use HTTP URLs, not define your own URI scheme. Because Android App Links use HTTP URLs that link to a website domain you own, so no other app can use your links. You can check the comparison of deep link and Android App links from here
Now you can easily add a URI scheme by using Android Studio option: Tools > App Links Assistant. Please refer the detail to Android document: https://developer.android.com/studio/write/app-link-indexing.html
Complementing the @DanielLew answer, to get the values of the parameteres you have to do this:
URI example: myapp://path/to/what/i/want?keyOne=valueOne&keyTwo=valueTwo
in your activity:
Intent intent = getIntent();
if (Intent.ACTION_VIEW.equals(intent.getAction())) {
Uri uri = intent.getData();
String valueOne = uri.getQueryParameter("keyOne");
String valueTwo = uri.getQueryParameter("keyTwo");
}
I strongly recommend that you not define your own scheme. This goes against the web standards for URI schemes, which attempts to rigidly control those names for good reason -- to avoid name conflicts between different entities. Once you put a link to your scheme on a web site, you have put that little name into entire the entire Internet's namespace, and should be following those standards.
If you just want to be able to have a link to your own app, I recommend you follow the approach I described here:
Another alternate approach to Diego's is to use a library:
https://github.com/airbnb/DeepLinkDispatch
You can easily declare the URIs you'd like to handle and the parameters you'd like to extract through annotations on the Activity, like:
@DeepLink("path/to/what/i/want")
public class SomeActivity extends Activity {
...
}
As a plus, the query parameters will also be passed along to the Activity as well.
