Track webpage in background

Question

I want to design an app based on a web-service, also I want to open some background page according to web-service data via WebView to be able to track that pages in GoogleAnalytics.

To accomplish this ideas I wrote the following singleton and It's work as I expected but there is strange memory leak behavior in this code that I assume it caused form WebView bug!

public class SiteLoader {
    private static SiteLoader mSiteLoader;

    private WebView mWebView;

    private Context c;

    public enum LoaderUri {
        MUSIC_URI, VIDEO_URI, BOOK_URI
    }

    private SiteLoader(Context c) {
        this.c = c.getApplicationContext();
    }

    public static SiteLoader getInstance(Context c) {
        if (mSiteLoader == null)
            mSiteLoader = new SiteLoader(c);

        return mSiteLoader;
    }

    public void trackUri(LoaderUri uri, String extraData) {
        // Load new progress
        switch (uri) {
            case MUSIC_URI:
                getWebView().loadUrl(Constants.HOST_PREFIX + "/music/?id=" + extraData);
                break;
            case VIDEO_URI:
                getWebView().loadUrl(Constants.HOST_PREFIX + "/video/?id=" + extraData);
                break;
            case BOOK_URI:
                getWebView().loadUrl(Constants.HOST_PREFIX + "/book/?id=" + extraData);
                break;
        }
    }

    public void destroyTracker() {
        if (mWebView != null) {
             mWebView.destroy();
             mWebView = null;
        }
    }

    private WebView getWebView() {
        if (mWebView == null) {
            mWebView = new WebView(c);
            mWebView.getSettings().setJavaScriptEnabled(true);
        }

        return mWebView;
    }
}

Any ideas to how get rid from this situation or is there any other alternative way to tack the page directly in web-service?

Test case activity:

public class TestActivity extends Activity {
    @Override 
    public void onResume() {
        super.onResume();
        SiteLoader.getInstance(this).trackUri(LoaderUri.VIDEO_URI, "en");
    }

    @Override 
    public void onPause() {
        super.onResume();
        SiteLoader.getInstance(this).destroyTracker();
    }

    @Override
    public void onCreate(Bundle mBundle) {
        super.onCreate(mBundle);
        Toast.makeText(this, "System is running", Toast.LENGTH_LONG).show();
    }
}

Thanks in Advance...

Answer 1

After discussing with the OP, it appears that there is no memory leak per se in this case; rather that the WebView is a memory intensive component that consumes a relatively high amount of RAM when used.
