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 show error of missing classes. Is it possible to execute JS code in Android? Thank you.

AndroidJSCore is a great one. And here is another little library I wrote for evaluating JavaScript:
It creates a WebView behind the scenes. Works on Android version 3 and newer.

You can use Webview which inherits View class. Make an XML tag and use
findViewById() function to use in the activity. But to use the JavaScript, you can make a HTML file containing the JavaScript code. The example blelow might help.
Remember that the JS will run on WebView, not in native environment, thus you might experience a lag or slow FPS in emulator. However when using on an actual phone, the code may run fast, depending on how fast is your phone.

http://divineprogrammer.blogspot.com/2009/11/javascript-rhino-on-android.html will get you started. ScriptEngine is a java thing. Android doesn't have a JVM but a DalvikVM which is not identical but similar.

UPDATE 2018: AndroidJSCore has been superseded by LiquidCore, which is based on V8. Not only does it include the V8 engine, but all of Node.js is available as well.
Degrassi the next generation download. Original answer:AndroidJSCore is an Android Java JNI wrapper around Webkit's JavaScriptCore C library. It is inspired by the Objective-C JavaScriptCore Framework included natively in iOS 7. Being able to natively use JavaScript in an app without requiring the use of JavaScript injection on a bloated, slow, security-constrained WebView is very useful for many types of apps, such as games or platforms that support plugins. However, its use is artificially limited because the framework is only supported on iOS. Most developers want to use technologies that will scale across both major mobile operating systems. AndroidJSCore was designed to support that requirement.

For example, you can share Java objects and make async calls:

You can use
Rhino library to execute JavaScript without WebView.
Download Rhino first, unzip it, put the js.jar file under libs folder. It is very small, so you don't need to worry your apk file will be ridiculously large because of this one external jar.
Here is some simple code to execute JavaScript code.
You can see more details at my post.

Season 1 spongebob. 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:
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.

The javax.script package is not part of the Android SDK. You can execute JavaScript in a WebView, as described here. You perhaps can use Rhino, as described here. You might also take a look at the Scripting Layer for Android project.

Given that ScriptEngineManager and ScriptEngine are part of the JDK and Android SDK is not the same thing as the JDK I would say that you can't use these classes to work with JavaScript under Android.
You can check the Android SDK's reference documentation/package index to see what classes are included (what can you work on Android out of the box) and which of them are missing.

I just found the App
JavaScript for Android , which is the Rhino JavaScript engine for Java. It can use all Java-classes, so it has BIG potential. The problem is it might be slow, since it is not really optimized (heavy CPU load). There is another JavaScript engine named Nashorn, but that unfortunately doesn't works on Google's DalvikVM Java engine (does not support the optimizations of Oracle Java engine). I hope Google keeps up with that, I would just love it!
