Initialization is a very important step; before initialization, none of the methods on the Sentiance SDK interface will work, with the exception of getInstance(), init() and getInitState().

Create an Application Class

Initialization must be done in the onCreate() method of your Application class. If you don't already have a custom application class, first create a new class that extends Application.

import android.app.Application;
public class MyApplication extends Application {
    @Override
    public void onCreate() {
    }
}

Then reference this new class in the application tag of the AndroidManifest.xml

<application android:name="com.example.appname.MyApplication">
  <!-- Activities -->
</application>

Call the SDK init Method

In the onCreate() method of your Application class, call init() and pass the SdkConfig you created in the previous step, plus an instance of OnInitCallback to handle the initialization result.

MyApplication.java
@Override
public void onCreate() {
    // Creation of SdkConfig here, see previous step
    
    OnInitCallback initCallback = new OnInitCallback() {
        @Override
        public void onInitSuccess() {
        }
        @Override
        public void onInitFailure(InitIssue issue, @Nullable Throwable th) {
        }
    };
        
    Sentiance.getInstance(this).init(sdkConfig, initCallback);
}

Upon successful initialization, onInitSuccess() will be called. If it fails, onInitFailure() will be called with an appropriate InitIssue.
