Android WebView prevents page reloading

Question

I have a Phonegap-related application that opens a PDF viewer at the click of a button. I did this with the FileOpener2 plugin.

When I return to the application from the PDF viewer, the result will differ depending on the versions of Android.

In Android 4. * the application remains where it should be before leaving the application. However, in Android 2.3.7, WebView reloads the application, which I do not expect.

I already tried changing android: launchmode to singleTask or singleInstance without success.

How can I avoid reloading the page when I return to the Phonegap application?

Thanks in advance!

Update 1

I changed the Cordova or Phonegap CordovaWebViewClient class, which extends WebViewClient with

@Override
public void onLoadResource(WebView view, String url) {
    if (url.equals("file:///android_asset/www/index.html")) {
        if (this.firstLoad) {
            this.firstLoad = false;
        } else {
            view.stopLoading();
        }
    }

onLoadResource , .
