Android App link - Open a url from app in browser without triggering App Link

问题

I have enabled App linking in my application. It works fine. But in my application there are some scenarios where i cannot handle the incoming url. In those cases i want to redirect that url to the default browser in the device.

Currently what i have tried doing is using intents to open browser with the url, but it again redirects to my app itself. The app link is of the format ->

https://<domain>/<prefix>/<params>

so depending on the params, i would like to either handle the app link in the app itself or redirect it to the default browser. Below is the code i tried to open the browser with the above url

val browserIntent = Intent(Intent.ACTION_VIEW, Uri.parse(appLinkModel.url))
browserIntent.addCategory(Intent.CATEGORY_APP_BROWSER)
browserIntent.resolveActivity(packageManager)?.let {
    startActivity(browserIntent)
}

I tried excluding the addCategory() line but the results are the same. Either the app crashes(hence the resolveActivity()), or app opens itself in a loop.

WHAT I WANT TO DO

So what i want to do is redirect the url to the default browser(or show a chooser WITHOUT my app in it), without triggering the app link again and again. So is this possible?

回答1:

String data = "example.com/your_url?param=some_param"
Intent defaultBrowser = Intent.makeMainSelectorActivity(Intent.ACTION_MAIN, Intent.CATEGORY_APP_BROWSER);
defaultBrowser.setData(data);
startActivity(defaultBrowser);

this technique (using makeMainSelectorActivity) will force the link to open in the device's default browser

Note - makeMainSelectorActivity only works for API level 15 and above.

If you need to support API levels lower than 15, you could try this hack

        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://stackoverflow.com/questions/58800240/android-app-link-open-a-url-from-app-in-browser-without-triggering-app-link"));
        Intent chooseIntent = Intent.createChooser(intent, "Choose from below");
        startActivity(chooseIntent);

This will open all the installed web browsers from which user can choose!

Unfortunately, we can't exclude any certain URL, since Android doesn't provide that option.

But you can handle using path prefix.

// To handle:
http://myhost.com/v/page1?id=123
// To exclude:
http://myhost.com/v/page2?id=123

then in manifiest

<data android:scheme="http"
      android:host="myhost.com"
      android:pathPrefix="/v/page1" />
