Tags:

[x] Rendering of LaTeX Math inside of an Android View
[x] No dependency on WebView
[x] Easy to use.

Installation from the command line

git clone https://github.com/gregcockroft/AndroidMath.git

cd AndroidMath
./gradlew installDebug

Installation for Android Studio

Clone this project, run CDep. CDep pulls in the freetype dependency.

git clone https://github.com/gregcockroft/AndroidMath.git
cd AndroidMath/mathdisplaylib
./cdep

Open the project in Android Studio

Using library in your app

HelloAndroidMath For a complete simple project

This is using jitpack.io Add below lines to root's build.gradle

    allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }

Add below lines to apps's build.gradle

dependencies {
            implementation 'com.github.gregcockroft:AndroidMath:ALPHA'
    }

<ConstraintLayout ...>

    <TextView
        android:id="@+id/description"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello Math!"
        app:layout_constraintBottom_toTopOf="@+id/mathview"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <com.agog.mathdisplay.MTMathView
        android:id="@+id/mathview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="56dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@id/description" />


</ConstraintLayout>

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(activity_main)

        mathview.latex = "x = \\frac{-b \\pm \\sqrt{b^2-4ac}}{2a}"
    }

API

Look at MTMathView This is the central access class.

iosMath This project is a Kotlin port for Android of the iosMath project
Freetype is used for rendering glyphs and font metrics.
Freetype jni was copied as a starting point to access the native freetype library.
