I made HTML file with JavaScript functions in and Android UI to call these functions. I don't know how to call JS in web views on Android. Please help.
Example:

```
//JavaScript
<script>
function doSomething(){
//do something
}
</script>

//Android Java
Button clickButton = (Button) findViewById(R.id.button);
clickButton.setOnClickListener( new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            //call JS function doSomething()
        }
});

```
