Deep-linking on Android

I’ve run into an issue when using a deep-linking scheme for my nativescript-angular app. I can receive the Intent just fine, but the entire angular app seems to be re-initialized on each deep-link received.

Using the basic template-hello-world-ng template I’ve done this:

In AndroidManifest.xml added the following to the NativeScriptActivity:

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="deeplink" />
</intent-filter>

And added this to AppComponent’s OnInit:

application.android.on(application.AndroidApplication.activityResumedEvent, (args) => {
    if (args.activity.getIntent().getAction() === android.content.Intent.ACTION_VIEW) {
        const intentData = args.activity.getIntent().getData();
        console.log(`Android received ACTION_VIEW intent, with data: ${intentData}`);
    }
});

Now when I launch the app, suspend it, and then launch the url “deeplink://test”, the app resumes and I can receive the intent just fine. But it seems the entire angular app and all components are initialized again from scratch, without destroying the old ones.

Test project demonstrating the issue here: https://github.com/ddfreiling/tns-ng-deeplink/tree/bug-report

Here’s my logging output when doing this:

It also seems I’m receiving the ACTION_VIEW intent again when I just exit the app and resume normally, without using a deep link (after having received one earlier).

@dameety Nope, no response from the dev team, and I haven’t found a way to fix it myself yet.

HI @ddfreiling, Did you get this to work? i wanna include the deep link feature in my app and needed a guide to do so.
