Extra padding at bottom of WebView

MathJaxView

MathJaxView is a custom view extending WebView and offers offline support for MathJax for Android Apps.

Setup

You can add MathJaxView to your Android Studio project in two ways:

Using a remote Maven repository (jCenter)
Using AAR file downloaded from bintray

1. Setup from a remote Maven repository (jcenter)

Add implementation 'io.github.sidvenu.mathjaxview:mathjaxview:1.0.7' into dependencies section of your module build.gradle file.

2. Setup from local .aar file

You can download the latest version of MathView from Bintray.

Import the module from local .aar file

Click File - New - New Module (yes, not Import Module) -> Import .JAR/.AAR Package, and find out where the file located.

Add dependency

Click File -> Project Structure -> Dependencies, and then click the plus icon, select 3. Module Dependency.

Usage

The usage of MathJaxView is similar to that of TextView. Refer to the sample app (MathJaxTest) for usage.

MathJax configuration

The default config is set to use single dollar symbols ($) for inline formula and double dollar symbols ($$) for displayed formula. You can use the view.setConfig(String) method to change the configuration to anything of your choice. The default config is set as follows:

config = "MathJax.Hub.Config({" +
                "    extensions: ['fast-preview.js']," +
                "    messageStyle: 'none'," +
                "    \"fast-preview\": {" +
                "      disabled: false" +
                "    }," +
                "    CommonHTML: {" +
                "      linebreaks: { automatic: true, width: \"container\" }" +
                "    }," +
                "    tex2jax: {" +
                "      inlineMath: [ ['$','$'] ]," +
                "      displayMath: [ ['$$','$$'] ]," +
                "      processEscapes: true" +
                "    }," +
                "    TeX: {" +
                "      extensions: [\"file:///android_asset/MathJax/extensions/TeX/mhchem.js\"]," +
                "      mhchem: {legacy: false}"+
                "    }" +
                "});";

Asset management

Make sure you add the extra MathJax assets that accompanies the change in config to your app (other than the one provided by the library).

You can do this by creating a MathJax folder in your assets folder that has the extra MathJax assets. The path to MathJax that you can use in your config can be: file:///android_asset/MathJax/extensions/TeX/mhchem.js.

Thanks

Sincere thanks to jianzhongli for their MathView project that served as an inspiration for this project.

How is it different from MathView?

It features the latest MathJax version (v2.7.5).
It does not have KaTeX, reducing the size of library. If you want KaTeX,there is a separate library for that: KaTeXView.
Supports API level 15, targeting 100% of the Android devices as per documentation.
Very small size - 1.36MB that was stripped down from 67.59MB of MathJax assets.

Documentation

The code of MathJaxView (a single small file) is well documented and anyone can easily understand it. Please view the code and try to understand it yourself. If you don't, please raise a issue with the help wanted label. Furthermore, I've created a module that tests out the features of this library, called mathjaxtest. You can check it out for the library usage.

Issues

Please report any issues that you encountered, not limited to performance improvements and updating the MathJax assets.

Pull Requests

PRs are an all-time welcome provided you follow the coding style similar to that already existing in the project.
