Can I use a String resource to generate the deeplink in a Jetpack Navigation XML file?

Question

Let's say I have the following buildType section in my Gradle file:

buildTypes {
    debug {
        ...
        resValue "string", "DEEPLINK_EXAMPLE", "appnamedebug://detail/{detail_id}"
        ...
    }
    release {
        ...
        resValue "string", "DEEPLINK_EXAMPLE", "appname://detail/{detail_id}"
        ...
    }
  }

I wanted to use the generated String resource as a deeplink in my Jetpack Navigation XML file as follows:

<deepLink app:uri="@string/DEEPLINK_EXAMPLE" />

I've tried something similar to this, but the Intent Filters don't show up when I looked at the output file from ./adb shell dumpsys package r.

Is this even possible in the first place? If it is, is there something I missed?

Answer 1

That method in the question just leads to the manifest having the intent filter as follows:

<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="http" />
    <data android:scheme="https" />
    <data android:host="string" />
    <data android:path="/DEEPLINK_EXAMPLE" />
</intent-filter>

I guess it's a pipe dream then.

Well, in the end I had to resort to the previous method: copying the Navigation Graphs to the debug and release source sets and set the deeplink URIs there accordingly.

So the Nav Graph in the debug source set would have this:

<deepLink app:uri="appnamedebug://detail/{detail_id}" />

While the Nav Graph in the release source set would have this:

<deepLink app:uri="appname://detail/{detail_id}" />

I'm actually not sure whether to keep the Nav Graph in the main source code, or remove it so the ones in the debug/release source sets have precedence.
