Rendering problems

[NAYIR55]

I hope this project stil alive, I'm very interested in adding math formulas

Tools:

• Android Studio 2.2

I did follow the steps to import the dependencies but this error suddenly appeared:

java.lang.NoSuchMethodError: io.github.kexanie.library.MathView.getSettings()Landroid/webkit/WebSettings;

Here is my layout:

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
                                             xmlns:app="http://schemas.android.com/apk/res-auto"
                                             xmlns:auto="http://schemas.android.com/apk/res-auto"
                                             xmlns:tools="http://schemas.android.com/tools"
                                             android:layout_width="match_parent"
                                             android:layout_height="match_parent">

    <io.github.kexanie.library.MathView
        android:id="@+id/formula_test"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        auto:text="When \\(a \\ne 0\\), there are two solutions to \\(ax^2 + bx + c = 0\\)
        and they are $$x = {-b \\pm \\sqrt{b^2-4ac} \\over 2a}.$$"
        auto:engine="MathJax">

    </io.github.kexanie.library.MathView>
</android.support.constraint.ConstraintLayout>

I don't know what is wrong

Hope you can solve this problem

Thanks
