I need to make a WebView show some web pages where some parts are offline (on the SD card) and some are online (retrieved via http). For instance, som pictures or javascript files may be local on the sd card, and some may be online. Target is Android 1.6, and I have full control over the server, and the files on the server.

I created a chess game for Android - Chess Walk, it's on Market for free under title "Chess Walk (BETA)". It has online mode (you can play on Free Internet Chess Server) and offline mode. The built-in chess engine is not very good, I'll probably focus now on improving its strength and style of play.

I am very new to both android webkit and javascript. I have a web page with 3 links (say A,B,C). When I open that page on my PC browser(Chrome), and click on the links, A opens in the same browser window whereas B and C pops up a new window. In my application I am loading the original URL in a WebView. I have implemented my WebViewClient and overridden the shouldOverrideUrlLoading. I am getting the call to shouldOverrideUrlLoading whenever I click on A, but not getting it when I click on B or C?

View 2 Replies View RelatedI'm loading a URL into a WebView and I'm having difficulty setting the "scale" of the web-page. Specifically, the web-page is too big (800x600) for the screen, so my thought is to use "setInitialScale(50)" to reduce the size. Here is some sample code that doesn't work (i.e. the web-page doesn't scale to 50%)
WebView wv = (WebView)findViewById(R.id.webview);
wv.loadUrl("http://www.example.com/android/symptom");
wv.setInitialScale(50);
I also tried switching the order of the function calls but I get the same resultŠi.e.,
WebView wv = (WebView)findViewById(R.id.webview); wv.setInitialScale(50); wv.loadUrl("http://www.example.com/android/symptom");
As an alternative, I have tried to use the "zoomOut()" function like this:
WebView wv = (WebView)findViewById(R.id.webview);
wv.loadUrl("http://www.example.com/android/symptom"); wv.zoomOut();
This approach works for a split second, and then the image reverts to its original size.

i have an application which loads urls from a website. Now i want that the aplication uses the cache when offline. But i just get the failure site which says that im not connected to the website. At first i set the Cachmode to Load_Normal but this doesnt help. Next i tried a realy "silly" approach using the ConnectivityManager:
cm = (ConnectivityManager) this.getSystemService(Activity.CONNECTIVITY_SERVICE);
if(cm.getActiveNetworkInfo().isConnected()){
mfnWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
mfnWebView.loadUrl(url);
}
else{
mfnWebView.getSettings().setCacheMod e(WebSettings.LOAD_CACHE_ELSE_NETWORK);
mfnWebView.loadUrl(url);
}
but this just leads to crashing the application. Is there a simple way to load the cache when offline and existing. And just if not existing showing the failure message.
I would like to a WebView to run some JavaScript before loading the rest of the page. This JavaScript should run in the same context of the page, just as if extra <script> content were added before any other <script> content. This is not possible with add Java script Interface() since I want to set up some instance variables, before the page scripts are run, so that the page scripts can use them.

I'm got a custom webview setup which is working pretty well, but I'd like to be able to either:
1, change the url hash without the webview reloading the page (it would lose the state of my js app)
2, call some js that sits within my web page from within android. I can't change any JS within the site, unfortunately, so can't custom write any js to put on the site especially for the job, the only stuff I have control over is the Android app.
Can anyone think of a way of doing either of these?
I have an android application that loads web pages in an activity with a WebView. I am using the retrieving the page manually and using WebView's loadDataWithBaseURL to display it on screen. Everything there is fine.
Now, i am trying to override the Back button press to simulate going back in the WebView history stack. I am able to override the Back button press, i can see that there is a history stack in the WebView, i can see that the history url is correct, but when i call WebView's goBack() method, it displays a blank page.
If i use WebView's loadUrl method, the Back button with an override works as intended. But why.... If i need to handle this manually, how do i start messing with history pages?
Can Webview tell me that I didn't get a HTTP 200 OK HTTP response code? I really don't want to display the Android Web Page Not Available screen inside my app.
View 3 Replies View RelatedI use webview app to open a web page (url). This web page has a form with a select element to choose. I would like to tell to select a specific value without click the element.
View 2 Replies View RelatedAs I say in the topic, I want my WebView to prevent from reloading the webpage when another activity comes to the foreground or just when the orientation is changed. The reason why is because the WebView content is generated by Javascript/AJAX almost completely. After searching on a couple of forums, I found out many people suggested to use "saveState" and "restoreState" methods, but when I look the documentation, it says:Please note that this method no longer restores the display data for this WebView. See savePicture(Bundle, File) and restorePicture(Bundle, File) for saving and restoring the display data.So, here I was using that savePicture and restorePicture as it follows:protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); some other lines
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webview);
if (savedInstanceState == null){
loadInicialWebUi();
}else{ mWebView.restoreState(savedInstanceState);
boolean restoredPic = mWebView.restorePicture(savedInstanceState, new File("savedDisplayWebView.temp"));
Log.d(TAG, "restored Picture:" + restoredPic);
@Override protected void onSaveInstanceState(Bundle savedInstanceState) {
mWebView.saveState(savedInstanceState);
boolean savedPic = mWebView.savePicture(savedInstanceState, "savedDisplayWebView.temp");
Log.d(TAG, "saved Picture:" + savedPic);
super.onSaveInstanceState(savedInstanceState);
}And well, those logs were revealing that it saves the picture, but it couldn't restore it. I suspect there might be something about the File references, but I couldn't think of a better way of getting the reference of the File I created when saving the state.Anyone thrilled?
I'm trying to load/reference images from the app's assets folder from within a HTML page in a WebView. Unlike in most of the examples the HTML page itself is not located in the assets folder but is loaded from a server via http. The background of this question are some performance improvements which should reduce the loading time (and the amount of transferred data) by loading static images directly from the device. I'm not sure if Android has some restrictions here because there's a certain possibility to exploit the app by allowing access to the local file storage from a remotely loaded webpage.
View 2 Replies View RelatedSome time ago we discussed in a separate thread whether it was possible to save web pages from the Browser app for browsing off-line when an internet connection was not available.At the time the simplest workaround that was suggested involved emailing a link to oneself, opening the link and saving the web page on a PC, then copying the saved page to the Hero's SD card.In fact, if all you want to save is the text content of a web page (without any pictures or other linked content), this can be done straight from the Hero Browser. Long-pressing on a link brings up various options including one, "Save link", which actually saves the target of the link to the downloads folder on the SD card. If the target is an html file then that file (and only that file) will be saved.I still think it would be good to have a "save web page" option which saves not just the text but the images and other linked content as well. But, in the meantime, this "Save link" option is a good deal better than nothing.
