Can't even implement the AppIntro

The erros that I have don’t allow me to even run the program:

**I tried to use the code they give us in the AppIntro and even tried some variations from some youtube tutorials but all give me errors **:

package com.example.biscates;

import android.content.Intent;
import android.graphics.Color;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v4.content.ContextCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.Toast;

import com.github.paolorotolo.appintro.AppIntro;
import com.github.paolorotolo.appintro.AppIntroFragment;

public class AppIntroActivity extends AppIntro {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        addSlide(AppIntroFragment.newInstance("Hey", "description", R.drawable.testingImage4, Color.BLUE));
        // Note here that we DO NOT use setContentView();

        // Add your slide fragments here.
        // AppIntro will automatically generate the dots indicator and buttons.

        // Instead of fragments, you can also use our default slide.
        // Just create a `SliderPage` and provide title, description, background and image.
        // AppIntro will do the rest.
        SliderPage sliderPage = new SliderPage();
        sliderPage.setTitle(title);
        sliderPage.setDescription(description);
        sliderPage.setImageDrawable(image);
        sliderPage.setBgColor(backgroundColor);
        addSlide(AppIntroFragment.newInstance(sliderPage));

        // OPTIONAL METHODS
        // Override bar/separator color.
        setBarColor(Color.parseColor("#3F51B5"));
        setSeparatorColor(Color.parseColor("#2196F3"));

        // Hide Skip/Done button.
        showSkipButton(false);
        setProgressButtonEnabled(false);

        // Turn vibration on and set intensity.
        // NOTE: you will probably need to ask VIBRATE permission in Manifest.
        setVibrate(true);
        setVibrateIntensity(30);
    }

    @Override
    public void onDonePressed(Fragment currentFragment){
        super.onDonePressed(currentFragment);
        Intent intent = new Intent(getApplicationContext().MainActivity.class);
    }

    @Override
    public void onSkipPressed(Fragment currentFragment) {
        super.onSkipPressed(currentFragment);
        Toast.makeText(MainActivity.this, "App Intro Ended", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onDonePressed(Fragment currentFragment) {
        super.onDonePressed(currentFragment);
        // Do something when users tap on Done button.
    }

    @Override
    public void onSlideChanged(@Nullable Fragment oldFragment, @Nullable Fragment newFragment) {
        super.onSlideChanged(oldFragment, newFragment);
        // Do something when the slide changes.
    }
}

Thanks for eveything, the AppIntro is now looking great thanks to you 😄

So your code has multiple problems that the IDE is already telling you:

onDonePressed

You have the onDonePressed function defined twice in you code. You must remove one of the two functions.

onSkipPressed

You’re referencing MainActivity.this while your activity is called AppIntroActivity. So you should change your onSkipPressed code to:

    @Override
    public void onSkipPressed(Fragment currentFragment) {
        super.onSkipPressed(currentFragment);
        Toast.makeText(AppIntroActivity.this, "App Intro Ended", Toast.LENGTH_SHORT).show();
    }

SliderPage

The code is failing since you’re not importing the SliderPage class. Please make sure that you have those 3 lines on the top of your activity (you have only two at the moment).
