Getting an error in Android studio when integrating the Helpshift API (null pointer exception)

I'm getting a null point exception in Android studio. I'm trying to integrate Helpshift into my current app. The null point is being called on the help button I think. The error I'm getting is:

java.lang.NullPointerException: Attempt to invoke interface method 
'void com.helpshift.CoreApi.updateApiConfig(java.util.Map)' on a null object reference

My code looks like

package com.example.leoconnelly.connexus;




public class MainActivity extends AppCompatActivity {

ImageButton FindCareButton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


//THE PURPLE BUTTON!!!!!!!
    FindCareButton = (findViewById(R.id.find_care_button));

    FindCareButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            openFindCare();
        }
    });

    /*
    GetStartedButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            openSearchActivity();
        }
    });
     */

    ImageButton helpButton = (ImageButton) findViewById(R.id.imageButton13);
    helpButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            ApiConfig.Builder configBuilder = new ApiConfig.Builder();
            configBuilder.setRequireEmail(true);
            configBuilder.setEnableTypingIndicator(true);
            com.helpshift.support.Support.showConversation(MainActivity.this, configBuilder.build() );


        }
    });


}

public void openFindCare () {
   Intent mainActivityToFindCare = new Intent (this, 
HealthCenterListActivity.class);
    startActivity(mainActivityToFindCare);
}

}

I'm not exactly sure what it's pointing too. I'm trying to open FAQs from Helpshift.

You are missing the InstallConfig for the API. Try adding it in the Calling Activity.

import com.helpshift.Core;
import com.helpshift.All;
import com.helpshift.InstallConfig;
import com.helpshift.exceptions.InstallException;

Core.init(All.getInstance());
        InstallConfig installConfig = new InstallConfig.Builder()
                .setEnableInAppNotification(true)
                .build();

        try {
            Core.install(getApplication(),
                    API_KEY,
                    DOMAIN,
                    APP_ID, installConfig);


        } catch (InstallException e) {
            android.util.Log.e("Helpshift", "install call : ", e);
        }
