Основной поток Android слишком много работы

Я создаю свое первое приложение, но после добавления нескольких элементов макета, а точнее DrawerLayout, оно начало выдавать мне ошибку:

Я/Хореограф: Пропущено 126 кадров! Приложение может выполнять слишком много работы в своем основном потоке.

Вот мой код макета:

<!-- The main content view -->

Пожалуйста, мне нужно знать, что происходит.

Вот моя java, я думаю, она не такая уж и большая. Как я мог запустить его на асинхронном режиме?

package pl.webimpuls.wicms;

import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.MotionEvent;
import android.view.View;
import android.widget.RelativeLayout;
import com.crashlytics.android.Crashlytics;
import io.fabric.sdk.android.Fabric;

public class MainActivity extends AppCompatActivity {

private Toolbar toolbar;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Fabric.with(this, new Crashlytics());
    setContentView(R.layout.activity_main);

    RelativeLayout dw = (RelativeLayout)findViewById(R.id.dodaj_wpis);



}


public void dodajaaktualnosc(View view)
{
    Intent dodaj = new Intent(MainActivity.this, aktualnosci_dodaj.class);
    startActivity(dodaj);
}

public void czytajaktualnosc(View view)
{
    Intent czytaj = new Intent(MainActivity.this, aktualnosci.class);
    startActivity(czytaj);
}
public void leady(View view)
{
    Intent leady = new Intent(MainActivity.this, aktualnosci.class);
    startActivity(leady);
}
public void otworzstrone(View view)
{
    Intent otworzurl = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.webimpuls.pl"));
    startActivity(otworzurl);
}

}
