Question

I have an android app that register a custom url scheme (let’s say app://)

In the onResume() method of my main activity I get data from the url by calling getIntent().getData().

When I browse to a web page containing such a link (like app://action/1234) then getIntent().getData() return the info I need to take appropriate action. That’s fine.

Now I want to have a WebView in my app that does the same. Here’s my code :

WebView banner = ...
banner.setWebViewClient(new WebViewClient() {

    @Override
    public void onLoadResource(WebView view, String url) {

        if (url.startsWith("app://")) {

            try {
                Intent i = Intent.parseUri(url, Intent.URI_INTENT_SCHEME);
                startActivity(i);

                return true;

            } catch (URISyntaxException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            return false;

        }
    }
}

When I click on the link in the WebView, the onResume() method of the main activity is called BUT getIntent().getData() returns null.

I guess

Intent i = Intent.parseUri(url, Intent.URI_INTENT_SCHEME);
startActivity(i);

is not the good way to do it.

How should I do to reproduce the same event that happens when I click a link in the browser ?

EDIT:

My activity has android:launchMode="singleTop" and it seems to be the cause of my problem but if I don’t set the launch mode then another copy of the activity is launched (I don’t want that). I tried to handle the intent by overriding onNewIntent() and in the intent given to it I can see the data. But I want my app to react in the same manner with it’s launched from its inside or from another app then

Is it safe to do this ? :

@Override
public void onNewIntent(Intent intent) {
    getIntent().setData(intent.getData());
}

Answer 1

Intent i=new Intent(Intent.ACTION_VIEW, Uri.parse(url));

should do it.
