Crash when using slide library

I'm trying to use this slide library but I've had errors.

package com.rightside.meutesoureiro_controlesuacarteira;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import com.heinrichreimersoftware.materialintro.app.IntroActivity;
import com.heinrichreimersoftware.materialintro.slide.FragmentSlide;

public class MainActivity extends IntroActivity {

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

        addSlide(new FragmentSlide.Builder().background(android.R.color.white).fragment(R.layout.intro_1).build());
        addSlide(new FragmentSlide.Builder().background(android.R.color.white).fragment(R.layout.intro_2).build());
        addSlide(new FragmentSlide.Builder().background(android.R.color.white).fragment(R.layout.intro_3).build());
        addSlide(new FragmentSlide.Builder().background(android.R.color.white).fragment(R.layout.intro_4).build());

        //addSlide(new FragmentSlide.Builder().background(android.R.color.white).fragment(R.layout.intro_1).build());
    }
