Why is my class creation being skipped

Question

Okay this error for the life of me I can't figure out, to the point where I don't even know what to google anymore. This is a fragment of my initial class. (You can view the whole thing here)

   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.i("Avariel", "I am running");

        RealmManager realmManager = new RealmManager();

        Log.i("Avariel", "I have passed RM");

In it I am trying to create a class of Realm Manager (You can view the whole class here). At this point I can even get the "I am running Realm Manager's on Create"to show. When I debug it just freezes.

public class RealmManager extends Activity {

    public static final String TAG = MainFragmentActivity.class.getName();
    private Realm realm;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Log.i("Avariel REALM", "I am running Realm Manager's on Create");
        /**
         * https://realm.io/docs/java/latest/#getting-started
         * http://facebook.github.io/stetho/
         * https://github.com/uPhyca/stetho-realm
         * chrome://inspect/#devices
         */
       /* Stetho.initializeWithDefaults(this);
        Realm.init(this);
        Stetho.initialize(
                Stetho.newInitializerBuilder(this)
                        .enableDumpapp(Stetho.defaultDumperPluginsProvider(this))
                        .enableWebKitInspector(RealmInspectorModulesProvider.builder(this).build())
                        .build());

        realm = Realm.getDefaultInstance();
        realm.beginTransaction();
        Player player = realm.createObject(Player.class);
        player = player.create(01, "Gideon", "Barlock", "Orc", "Lawful Evil", "Fighter", "A wandering Warrior", 0, 30, 0, null, null, null, null, null, null, null, null, null, 0);
        realm.commitTransaction();
        Realm.init(this);

        RealmConfiguration config = new RealmConfiguration.Builder().build();
        Realm.setDefaultConfiguration(config);*/
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        realm.close();
    }

Meaning the log I see

05-27 22:38:13.477 32158-32158/com.example.gideonsassoon.avariel I/Avariel: I am running
05-27 22:38:13.559 32158-32158/com.example.gideonsassoon.avariel I/Avariel: I have passed RM

What have I done wrong here. You can view the full project here

Many thanks for your help,

Why does `RealmManager extends Activity`? – OneCricketeer May 27 '17 at 21:52 — OneCricketeer, May 27 '17 at 21:52

Never create an instance of an Activity yourself via the constructor.

Since RealmManager does not seem to be an actual activity (with a UI and such), remove extends Activity from your declaration of RealmManager. Then, you need to arrange to call methods on your RealmManager yourself, like any other Java object.

"I am running Realm Manager's on Create"

No you aren't. You called new, which called the default constructor, which never calls onCreate.

Try the following to create a regular Java object that manages some Realm object

public class RealmManager  {

    private final Context context;
    private final Realm realm;

    public RealmManager(Context context) {
        Log.i("Avariel REALM", "I am running Realm Manager"); 
        context = context;
        realm = Realm.getDefaultInstance();
    }

Plus,

RealmManager realmManager = new RealmManager(this);

I believe all that other code belongs in an Application class, not any Activity
