Storing parameter from JavaScript in Android

Question

I have a JavascriptInterface and a setter/getter in my Android code:

mWebView.addJavascriptInterface(new AccessibleMethods(), "Android");

private class AccessibleMethods {
    private boolean isWorking;
    public void setIsWorking(boolean working)
    {
        this.isWorking = working;
        // A toast message here of this.isWorking displays true
    }
    public boolean getIsWorking()
    {
        return this.isWorking;
    }
}

In my JavaScript code I call the function:

Android.setIsWorking(true);

But when I try to access isWorking in Java in another method or outside the class, it doesn't have the correct value.

AccessibleMethods methods = new AccessibleMethods();
methods.getIsWorking(); // returns wrong or no value

I need this for accessing a JavaScript variable onKeyDown.

Any suggestions?

If you want to share the data passed from the JavaScript, you should use the same instance of the object across the method calls, or use an instance variable.

private AccessibleMethods methods = new AccessibleMethods();
//... 
mWebView.addJavascriptInterface(methods, "Android");
//..
boolean isWorking = methods.getIsWorking();
