Please read following section, if you are using java for developing.

Please include implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" to your build.gradle

And make sure you are enabled Java 8 language features by add following to build.gradle

android {
    ...
    // Configure only for each module that uses Java 8
    // language features (either in its source code or
    // through dependencies).
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Setting up api key or secret

Kotlin

// set your api key and api secret. 
IAGSManager.getInstance(this).setApiKey("SET YOUR API KEY HERE", "SET YOUR SECRET KEY HERE")

Java

// set your api key and api secret. 
IAGSManager.Companion.getInstance(this).setApiKey("SET YOUR API KEY HERE", "SET YOUR SECRET KEY HERE");

Alternative, you can add api key IAGSApiKey and api secret IAGSSecretKey to metadata in your application manifests.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.indooratlas.groundsage.sdk.example">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity>
        ...
        </activity>

        <meta-data android:name="IAGSApiKey" android:value="SET YOUR API KEY HERE"/>
        <meta-data android:name="IAGSSecretKey" android:value="SET YOUR SECRET KEY HERE"/>
    </application>
</manifest>

Request venue information

Kotlin

class MainActivity : AppCompatActivity(), IAGSManagerListener {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        requestVenueDensityExample()
    }
    
    fun requestVenueInformationExample() {
        val sdk = IAGSManager.getInstance(this)
        // set your api key and api secret.
        sdk.setApiKey(
            "SET YOUR API KEY HERE",
            "YOUR SECRET KEY HERE"
        )
        // start to request venue information
        sdk.requestVenueInfo { venues, _ ->
            print(venues)
        }
    }
}

Java

public class MainActivity extends AppCompatActivity implements IAGSManagerListener {
    private final String TAG = MainActivity.class.getSimpleName();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        requestVenueInformationExample();
    }
    
    void requestVenueInformationExample() {
        IAGSManager sdk = IAGSManager.Companion.getInstance(this);
        // set your api key and api secret.
        sdk.setApiKey(
            "SET YOUR API KEY HERE",
            "YOUR SECRET KEY HERE"
        );
        // start to request venue information
        sdk.requestVenueInfo((iagsVenues, e) -> {
            Log.d(TAG, String.format("%s, %s", iagsVenues, e));
            
            return Unit.INSTANCE;
        });
    }
}

Register a callback and subscription

Kotlin

class MainActivity : AppCompatActivity(), IAGSManagerListener {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        sdk.setApiKey(
            "SET YOUR API KEY HERE",
            "YOUR SECRET KEY HERE"
        )
        sdk.addGroundSageListener(this)
        // start subscription to request venue density
        sdk.startSubscription()
    } 

    override fun onUpdateDensity(venueDensity: IAGSVenueDensity?) {
        println(String.format("update density = %s", venueDensity))
    }

    override fun onEnterDensityRegion(region: IARegion) {
        println(String.format("Enter region = %s", region))
    }

    override fun onExitDensityRegion(region: IARegion) {
        println(String.format("Exit region = %s", region))
    }
}

Java

public class MainActivity extends AppCompatActivity implements IAGSManagerListener {
    private final String TAG = MainActivity.class.getSimpleName();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
