JavaScript in the WebView does not run on the UI thread. It runs on the WebCore thread. The execute method also runs on the WebCore thread.

If you need to interact with the UI, you should use the following:

@Override
public boolean execute(String action, JSONArray args, final CallbackContext callbackContext) throws JSONException {
    if ("beep".equals(action)) {
        final long duration = args.getLong(0);
        cordova.getActivity().runOnUiThread(new Runnable() {
            public void run() {
                ...
                callbackContext.success(); // Thread-safe.
            }
        });
        return true;
    }
    return false;
}

If you do not need to run on the UI thread, but do not want to block the WebCore thread:

@Override
public boolean execute(String action, JSONArray args, final CallbackContext callbackContext) throws JSONException {
    if ("beep".equals(action)) {
        final long duration = args.getLong(0);
        cordova.getThreadPool().execute(new Runnable() {
            public void run() {
                ...
                callbackContext.success(); // Thread-safe.
            }
        });
        return true;
    }
    return false;
}
