Re: [android-developers] Bringing webview performance in line with browser app's?

I see the exact same thing and I'm baffled.

Tried the following:

        this.appView.getSettings().setRenderPriority(

            WebSettings.RenderPriority.HIGH);

        this.appView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

But I see like no difference in peformance in my webview.

Being faster in the browser than in the app is just depressing me.

I'm developing apps with Sencha Touch and PhoneGap, which uses a
webview to wrap an HTML5 application. I have been finding though that
scroll and animation performance inside my app's webview is
consistently underperforming the same application loaded in the same
phone's web browser.

I found a related discussion and have been experimenting with the code
I found in it:
http://stackoverflow.com/questions/3652583/enhance-webview-performance-should-be-the-same-performance-as-native-web-browser

...but have not found any improvements in performance. Here are two
apps where you can compare PhoneGap vs Browser performance for the
same code:
http://mobile.phillytechweek.com vs https://market.android.com/details?id=com.phillytechweek
http://draft.philadelphiaeagles.com vs https://market.android.com/details?id=com.philadelphiaeagles

Is there anyone that can shed some light on the nature of this
disparity or how it can be closed?

Here's what I'm currently working with:
----------------------

public class MyApp extends DroidGap {
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                super.setIntegerProperty("splashscreen", R.drawable.splash);

                super.init();

                super.appView.clearCache(true);
                super.appView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
        
super.appView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
                super.appView.getSettings().setSupportZoom(false);
                super.appView.getSettings().setSupportMultipleWindows(false);
                super.appView.getSettings().setBuiltInZoomControls(false);

                // disable caching
                try
                {
                        Method m = CacheManager.class.getDeclaredMethod("setCacheDisabled",
boolean.class);
                        m.setAccessible(true);
                        m.invoke(null, true);
                }
                catch (Throwable e)
                {
                        Log.i("MyApp","Reflection failed", e);
                }

                super.loadUrl("file:///android_asset/www/index.html");
        }
}
