Google finally realized the need of generating unique IDs for programmatically created views...

From API level 17 and above, you can call

View.generateViewId()

Then use View.setId(int).

In case you need it for targets lower than level 17, here is its internal implementation in View.java you can use directly in your project, put it in your util class or somewhere:

There is a hack:

Bind some Java object so that it can be called from Javascript with WebView:

addJavascriptInterface(javaObjectCallback, "JavaCallback")
Force execute javascript within an existing page by

WebView.loadUrl("javascript: var result = window.YourJSLibrary.callSomeFunction();
    window.JavaCallback.returnResult(result)");
(in this case your java class JavaObjectCallback should have a method returnResult(..))
