Firebase dynamic link not opening the app

I have developed an android app locally on my device (app not yet on android play store). I have the following logic to get deep link in MainActivity.

GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this, null)
            .addApi(AppInvite.API)
            .build();

    // Check if this app was launched from a deep link. Setting autoLaunchDeepLink to true
    // would automatically launch the deep link if one is found.
    boolean autoLaunchDeepLink = false;
    AppInvite.AppInviteApi.getInvitation(mGoogleApiClient, this, autoLaunchDeepLink)
            .setResultCallback(
                    new ResultCallback<AppInviteInvitationResult>() {
                        @Override
                        public void onResult(@NonNull AppInviteInvitationResult result) {
                            if (result.getStatus().isSuccess()) {
                                // Extract deep link from Intent
                                Intent intent = result.getInvitationIntent();
                                String deepLink = AppInviteReferral.getDeepLink(intent);

                                Toast.makeText(getApplicationContext(), deepLink, Toast.LENGTH_LONG).show();
                                // Handle the deep link. For example, open the linked
                                // content, or apply promotional credit to the user's
                                // account.

                                // ...
                            } else {
                                Log.d(TAG, "getInvitation: no deep link found.");
                            }
                        }
                    });

I built some dynamic links using Firebase console and open in mobile browser. But it is not opening my app and reaching to line String deepLink = AppInviteReferral.getDeepLink(intent);

Instead it is opening the URL in mobile browser itself.

How to open the app and handle deep link in activity while using firebase dynamic link??

Edit:

I have intent filter in the manifest file.

<activity android:name="MainActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
            <action android:name="android.intent.action.VIEW"/>
            <category android:name="android.intent.category.DEFAULT"/>
            <category android:name="android.intent.category.BROWSABLE"/>
            <data android:host="example.com" android:scheme="http"/>
            <data android:host="example.com" android:scheme="https"/>
        </intent-filter>
    </activity>

Action View and Action Main both are of different Intent category. So, you need to put them in different blocks like this:

 <activity android:name=".DynamicLinkActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <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:host="example.com"
                android:scheme="http" />
            <data
                android:host="example.com"
                android:scheme="https" />
        </intent-filter>
    </activity>

Alternatively, you could also provide the data in your intent-filter, like stated in the "regular" deep links doc (https://developer.android.com/training/app-indexing/deep-linking.html)

The intent filter would then look like the following :

        <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:host="https://XXYYZZ42.app.goo.gl/"  // <- Replace with your deep link from the console
                android:scheme="https"/>
        </intent-filter>

That said link can be obtained in your console, right here :
