Google Assistant Implementation in Android application with app actions

Process flow to create app action in android native:

Step 1) Create action.xml with Built-In Intent and defined in androidmanifest.xml

Step 2) Create deep link through firebase dynamic link SDK

Step 3) Map the Deeplink with built-in Intent in android action.xml

Step 4) Create the application in Playstore

Step 5) Upload the signed apk in Playstore as save in draft

Step 6) Open the app action testing tool from latest android studio after upload the apk in playstore

Step 7) Login the same google account in playstore, android studio and android device

Step 8) Make sure the check the same Locale language (en-Us) in Android device and action testing tool

Reference for Built-In Intent : https://developers.google.com/assistant/app/reference/built-in-intents/common/open-app-feature

Step 1) Create action.xml with Built-In Intent and defined in androidmanifest.xml

Create a new android project and goto New -> XML -> App Action Xml file

Step 2) Create deep link through firebase dynamic link SDK

Open firebase console and create a new project and goto dynamic link feature and add deeplink

Step 3) Map the Deeplink with built-in Intent in android action.xml

Paste the below codes in actions.xml in res/xml/actions.xml

<?xml version="1.0" encoding="utf-8"?>
<actions>
    <action intentName="actions.intent.OPEN_APP_FEATURE">
        <fulfillment urlTemplate="https://deeplink.page.link/open{?featureName}">
            <parameter-mapping
                intentParameter="feature"
                urlParameter="featureName" />
        </fulfillment>

        <parameter name="feature">
            <entity-set-reference entitySetId="FeatureEntitySet" />
        </parameter>
    </action>

    <action intentName="actions.intent.START_EXERCISE">
        <fulfillment urlTemplate="https://deeplink.page.link/start{?exerciseType}">
            <parameter-mapping
                intentParameter="exercise.name"
                urlParameter="exerciseType" />
        </fulfillment>
    </action>

    <action intentName="actions.intent.STOP_EXERCISE">
        <fulfillment urlTemplate="https://deeplink.page.link/stop" />
    </action>

    <entity-set entitySetId="FeatureEntitySet">
        <entity
            name="TripSummary"
            identifier="Trip" />
        <entity
            name="Profile"
            identifier="Profile" />
    </entity-set>

</actions>

Androidmanifest.xml



<meta-data
    android:name="com.google.android.actions"
    android:resource="@xml/actions" />



<activity android:name=".AssistantHandleActivity">

    <intent-filter>

        <action android:name="android.intent.action.MAIN" />


        <category android:name="android.intent.category.LAUNCHER" />

    </intent-filter>

    <intent-filter

        android:autoVerify="true"

        tools:targetApi="m">

        <action android:name="android.intent.action.VIEW" />



        <category android:name="android.intent.category.DEFAULT" />

        <category android:name="android.intent.category.BROWSABLE" />



        <data

            android:host="deeplink.page.link"

            android:scheme="https" />

    </intent-filter>

</activity>

Step 4) Create the application in Playstore

Step 5) Upload the signed apk in Playstore as save in draft

Step 6) Open the app action testing tool from latest android studio after upload the apk in playstore

Step 7) Login the same google account in playstore, android studio and android device

Step 8) Make sure the check the same Locale language (en-Us) in Android device and action testing tool



class AssistantHandleActivity : AppCompatActivity() {



    lateinit var featureTxt : TextView



    override fun onCreate(savedInstanceState: Bundle?) {

        super.onCreate(savedInstanceState)

        setContentView(R.layout.activity_main)



        featureTxt = findViewById(R.id.tv_feature)

        intent?.handleIntent()

    }



    private fun Intent.handleIntent(){

        when(action){

            Intent.ACTION_VIEW -> handleDeepLink(data)

            else -> showDefaultView()

        }

    }



    private fun handleDeepLink(data: Uri?){



        when(data?.path)

        {

            "/start" -> {   //Deeplink endpoint url

                val exerciseType = data.getQueryParameter("exerciseType").orEmpty()

                featureTxt.text = exerciseType

                Toast.makeText(applicationContext, "Start Type $exerciseType", Toast.LENGTH_LONG).show()

            }

            "/stop" -> {

                featureTxt.text = "Stop";

                // Stop the tracking service if any and return to home screen.

                Toast.makeText(applicationContext, "Stopped", Toast.LENGTH_LONG).show()

            }

            "/open" ->{

                val featureType = data?.getQueryParameter("featureName").orEmpty()

                featureTxt.text = featureType

                Toast.makeText(applicationContext, "Feature Type $featureType", Toast.LENGTH_LONG).show()

            }

            else ->{

                val featureType = data?.getQueryParameter("featureName").orEmpty()

                featureTxt.text = featureType

                Toast.makeText(applicationContext, "Else Feature Type $featureType", Toast.LENGTH_LONG).show()

            }

        }

    }



    

    private fun showDefaultView()

    {

        //Default activity goes here

    }



}

Issues:

1) Create preview not working in app action test tool

Solution: Restart the android studio

2) Error while upload the apk/bundle in playstore
