ArrayIndexOutOfBound

[vanlooverenkoen]

I tried to add your libary to my app. But when I create an IntroActivity like this:

public class TestActivity extends IntroActivity {
    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
        addSlide(new SimpleSlide
                .Builder()
                .title("title")
                .description("description")
                .build());
    }
}

I get this error:

[meierjan]

You are overwriting the wrong onCreate() method.

You do:

public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState)

It should be:

public void onCreate(Bundle savedInstanceState)

[edit]
(and of course the matching super class)

@meierjan Didn't even notice this 😆
Thanks for pointing that out.
