Simple javascript evaluator for android

This is a simple library to run javascript, Maybe it will help you to run javascript more easily without using big library.

Download

Using gradle

1. Add the JitPack repository to your build file. Add it in your root build.gradle at the end of repositories:

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

2.Add the dependency

	dependencies {
	    implementation 'com.github.adi-itgg:AITJsEval:v1.2'
	}

For less information, see implementation for maven/sbt/leiningen on jitpack.io Documentation

Usage

Initialize instance AITJsEval first. Context must using Application Context!

class App : Application() {

    override fun onCreate() {
        super.onCreate()
        // Initialize library first
        AITJsEval.initialize(applicationContext)
    }

}

Evaluate JavaScript

   val sc  = """
     (function f() {
         var d = "EvalExample:10"
         var i = parseInt(d.split(":")[1]) + 2 * 88 
         return d.split(":")[0] + " " + i
      }());
   """
   AITJsEval.get().enqueue("sample", sc, object : OnJavaScriptResponseListener {
      override fun onResponse(script: Script) {
         rText.value = script.result
         Toast.makeText(context, "Script executed", Toast.LENGTH_SHORT).show()
      }
   })

Result is EvalExample 186
