How to execute JavaScript on Android?

Question

I have code which uses ScriptEngineManager, ScriptEngine class for executing JavaScript code using Java. But it works fine in Java SE, and doesn\'t work in Android - SDK sh

Answer 1

I was also looking for a way to run javascript on Android and came across j2v8 library. This is a java wrapper for Google's v8 engine.

To use it add a dependency:

compile 'com.eclipsesource.j2v8:j2v8_android:3.0.5@aar'

It has pretty simple api, but I haven't found any docs online apart from javadoc in maven repository. The articles on their blog are also useful.

Code sample from this article:

public static void main(String[] args) {
    V8 runtime = V8.createV8Runtime();

    int result = runtime.executeIntegerScript(""
        + "var hello = 'hello, ';\n"
        + "var world = 'world!';\n"
        + "hello.concat(world).length;\n");

    System.out.println(result);

    runtime.release();
}
