Question

I want to be able to turn off overscroll (the glowing effect when reaching the top or bottom of a page in 2.3+) however I also want my code to run in older versions of android that don’t even have overscroll functionality. As per the documentation here: Android Backwards Compatibility I am using reflection in my custom webview class to call setOverScrollMode however everytime I call this on a device running 2.3.4, I get a NoSuchMethodException. Any idea why I can’t retrieve this method?

Strangely, if I just call setOverScrollMode without any reflection, it works, so the method is definitely there.

public class MyWebView extends WebView{

    public void compatibilitySetOverScroll(){
    try {
        Method mWebview_SetOverScroll = WebView.class.getMethod("setOverScrollMode", new Class[] { Integer.class } );
        /* success, this is a 2.3+ */
        if (mWebview_SetOverScroll != null) {
            try {
                mWebview_SetOverScroll.invoke(this, 2);
            } catch (InvocationTargetException ite) {       
                throw new RuntimeException(ite.getCause());
            } catch (IllegalAccessException ie) {
                System.err.println("unexpected " + ie);
            }               
        }
    } catch (NoSuchMethodException nsme) {
        /* failure, must be older device */
    }        
}
}

Try Integer.TYPE instead of Integer.class
