You have to make the call to LaunchComponent which can be done in onCreate first life-cycle callback function

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
     LaunchComponent (packageName, name);
}

import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;


public class MainActivity extends Activity {

public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
         LaunchComponent ("com.sec.android.app.controlpanel", "abc?");
    }


public void  LaunchComponent (String packageName, String name){
    Intent i = new Intent(Intent.ACTION_MAIN);
    PackageManager manager = getPackageManager();
    i = manager.getLaunchIntentForPackage(packageName);
    i.addCategory(Intent.CATEGORY_LAUNCHER);
    startActivity(i);
