Question

Is there any different behaviors about the WebView class on Android 2.2 and 3.1 ?

Here you go some informations I got testing the same app on two different devices, the first one with Android 2.2 and the another one 3.1

• The app’s target is 2.1
• The page that I want to access is an ASP.net page

Running on 2.2

• shouldOverrideUrlLoading is called normally
• onPageStarted and onPageFinished are called more than once
• onNewPicture from webview is called once, when the page ends the loading

Running on 3.1

• shouldOverrideUrlLoading isn’t called, only webView.load(url) is enough to do the same work
• onPageStarted and onPageFinished are called once
• onNewPicture from webview isnt called

My problem is. I need to show a dialog while the page is loading, and I don’t know how to do that with these differences.

If I create the dialog on onPageStarted and close it on onPageFinished it will show and close more than once on 2.2, but on 3.1 it will works fine

Otherwise, if I create the dialog on shouldOverrideUrlLoading and close it on onNewPicture it will works fine on 2.2 but on 3.1 it won’t even appear.

I used the following:

Android WebView progress bar

to put a progress bar on a webview while it was loading, your could implement the same, bringing up a view when the percentage loaded is less than 100% and taking it down when it is 100%. I implemented this for an Android >= 3.0 type device though.
