[android-developers] Re: WebView for HTML5 video and overriding onHideCustomView/onBackPressed in fragments

[AndroidUser253]

Mb there is no need to override onBackPressed in fragment 
because onHideCustomView is being called when I press back button anyway, 
but I as said the app crashes and I don't really understand why

[android-developers] Re: webview shouldInterceptRequest does not work on Android 5.0

[Carlos Farrington]

I found my problem.  Apparently in Android 5.0 shouldInterceptRequest will 
not be run if their is a problem with the url being loaded.   I was 
using loadDataWithBaseURL("foobar://, data, encoding, null) to load first 
page.  Since foobar:// is not a known prefix to a url or file the request 
was just being dropped.   I changed foobar to http:// or file:/// and 
everything started working as it did on Android 4.1.  I guess a check was 
introduced on 5.0 that was not being done before.

[android-developers] Re: WebView and ConnectivityManager.requestNetwork

[Doug]

OK, that's very different than what you first asked.

You will have to write shim to connect your app and the webview.  The page 
hosting the webview will have to provide a function to call that makes the 
necessary adjustments.  Then on the app side you call loadUrl with a 
javascript url to call that function with whatever parameters it needs.

Google "android webview inject javascript" for more details.  (Google 
answers most of your questions if you just ask it.)

 It's been a long time since I've been active on it, but I believe you

 callbacks exposed by webview, log a simple message, and see how it goes.

[android-developers] Re: WebView and ConnectivityManager.requestNetwork

[Krystian Lewandowski]

Hi,
the problem is that it is possible to get HTML skeleton (or whatever it is, 
because we do not control remote side) via specific route with additional 
implementation in shouldInterceptRequest. It is possible to inject loaded 
the content via WebView.loadDataWithBaseURL, but that's it. The question is 
how to inject additional resources to WebView?

Thank you,
Krystian

[android-developers] Re: WebView and ConnectivityManager.requestNetwork

[Doug]

Did you actually try WebViewClient.shouldInterceptRequest?  I'm looking 
through old code of mine that suggests it will work.  Also, you should try 
searching for "WebViewClient shouldInterceptRequest" to see what places 
like StackOverflow say.

[android-developers] Re: WebView and ConnectivityManager.requestNetwork

[Krystian Lewandowski]

Hi Doug,
I mean, I can get the page and there is onLoadResource I missed last time, 
but another question is - even if I get a resource, how to inject it? 
Callbacks, in this case, serve kind of notification purpose there is no way 
to replace loaded resource (whatever it actually is) or inject custom 
"loader" instead. At least at the moment I don't see a solution.

Thank you for ideas,
Krystian

[Doug]

It's been a long time since I've been active on it, but I believe you can 
intercept everything that passes through a url, both what would be loaded 
by navigation, image, and ajax.  Give it a try and implement all the 
callbacks exposed by webview, log a simple message, and see how it goes.

You could use a WebViewClient to intercept everything a WebView is trying

Just a guess, maybe Google Maps is trying to (incorrectly) redirect to the

[android-developers] Re: WebView - can't set its position..

[AmitNHB]

Please ignore this line: 


*webView**.setVisibility(View.GONE**);*

I'm setting it back to visible later on and like I said, the view starts at the 
very top instead of at 120.

[android-developers] Re: webview can not display twitter page

[Piren]

Webviews support redirecting without an issue. 
other than the suggestions on StackOverflow, i'd also check SSL certificate 
exception (i recall getting one on android versions below 2.3.3)

To verify you could either use the proper handler to catch those or just 
open the link in your native browser and see if it asks you to authorize 
the certificate (if it does, it means it will cause the failure in the 
webview).

Looks like this can be fixed by setting the user-agent:

webView.getSettings().setUserAgentString("Mozilla/5.0 (Linux; U; Android 2.0; 
en-us; Droid Build/ESD20) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 
Mobile Safari/530.17");

I am use ListView and each cell is WebView. So, I see that I must place

be I would be save Inflated view in array and return in GetView only view

[MathieuB]

Strangely, the exact same problem happened to me today. Was testing my map 
embedded in a webview on android 4.0.4...and around 3 times out of 4, it 
was showing a blank page...don't really understand why.

I'll try to call the destroy() method on the onDestroy() and see if it 
helps...

What is strange (and bad) is that everything works well in 2.3.x and 4.1

[android-developers] Re: Webview shows white blank page in Ice Cream Sandwitch

[Streets Of Boston]

Try this: Try call webtv.*destroy()* in your onDestroy() method. I'm just 
guessing here, but it's worth a try.

On a side-note: Don't call 'this.finish()' in your onPause() method. That 
is usually bad news.

[android-developers] Re: webview cookie sometimes null

[bob]

 

If you are calling Webview.loadUrl, *and* the URL is completely loaded, I 
would think the cookie would be there.

[android-developers] Re: webview cookie sometimes null

[emada.adame]

it was my understanding the webview.load(url) would get the cookie, 
everything else is just to make sure the webview can accept cookies. Which 
it dose do some times and other not so much. What would you recommend?

[android-developers] Re: webview cookie sometimes null

[bob]

 

The issue is probably that the cookie is not necessarily there.  I don't 
see anywhere in your code where you load any URL.


I'm pretty sure this function doesn't load anything:


public String getCookie (String url)


It probably just looks in a cookie cache.

Yeah I'm still having this issue, can anyone help? any ideas? Here is my 
new updated code:

 String server = settings.getString("server", "");
 String user = settings.getString("username", "");
 String passwd = settings.getString("passwd", "");
 webview = new WebView(this);
 WebSettings webSettings = webview.getSettings();
 webSettings.setJavaScriptEnabled(true);
 webview.setWebViewClient(new InsideWebViewClient());
 setContentView(webview);
 String credUrl = 
"http://"+server+"/services.php?sname=LoginService&isapp=true&username="+user+"&rawpassword="+passwd;
 //CookieSyncManager.createInstance(webview.getContext());
 //CookieSyncManager.getInstance();
 CookieManager cookieManager = CookieManager.getInstance();
 cookieManager.setAcceptCookie(true);
 webview.loadUrl(credUrl);
 String rawCookie = cookieManager.getCookie(server);
 mes(rawCookie);
 /*while(rawCookie == null){
SystemClock.sleep(1000);
rawCookie = cookieManager.getCookie(credUrl);
 }*/
 webview.loadUrl("http://"+server);

basically i just took out the cookie sync manager because it wasnt really 
doing anything and put a while loop in "that is now commented out" that was 
crashing the app :/

Re: [android-developers] Re: WebView / setBuiltinZoomControls / setOnTouchListener

[Sachin Gupta]

I think WebView stops firing onTouch event once the zoom-controls are shown 
on web-view.
I receive touch events even after using pinch zoom, provided zoom-controls 
are not shown yet.

If it is not must to also show the on-screen zoom-controls, following can 
be used to solve the issue.
myWebView.getSettings().setDisplayZoomControls(false);

It just stops to show the controls, pinch-zoom support is still available.

Yes, but to intercept the requests to the browser using a proxy (as
the OP suggests) requires rooting the device.



Feeding a WebView that's in your own app a URL like
"localhost:1234?src=www.foo.bar" requires rooting?


Not really an option, the web page is heavily Ajax based.

What would work though is, using a web proxy, that just passes most 
locations through and would send blank images or a 404 for certain urls.
Not really elegant and causing more traffic than blocking adapting the 
request on the phone, but it would be doable.


However  my naive asumption, that an Android phone is capable of setting 
/ using web proxies seems to be rather wrong.
After some googling I found out, that without rooting it seems to be 
impossible to set a proxy for a wifi connection (seems to be doable 
globally for mobile networks though)





Processing the received HTML / CSS, replacing links requires rooting?



To do it properly, and identify all of the links statically would
require a real considerable amount of analysis because of the
funkiness of HTML.  I previously suggested this approach to the OP,
but I doubt that it will work (and it just *feels* wrong), and even if
it does it's just abhorrently hacky..  So if he knows the structure of
the page, then perhaps, maybe this would be an acceptable hack, but
for the general case of writing a web browser, (as he says), hell no.



I knew Webkit via QT4 and am quite surprised about the rather reduced 
feature set provided by the Google java API. That's really a pity and 
I'm surprised these new features are only added for very new phones.
If shouldInterceptRequest() were suypported by older releases, then I 
wouldn't even have to use proxies.



It seems I have to wait one year or more to get a newer phone or to bite 
the bullet and root my phone.

Agree - this won't work for requests dynamically generated by JS, but it
might be acceptable depending on the requirements.

Re: [android-developers] Re: webview client, that intercepts requests on API 8

[Kristopher Micinski]

Yes, but to intercept the requests to the browser using a proxy (as
the OP suggests) requires rooting the device.

Sure, redirecting the links is one thing if you have control of the
webview, for arbitrary ajax traffic it's a no.

Not necessarily - if the WebView is under the developer's control (i.e.
there is no intention to do this system-wide), then it should be possible
to feed the WebView a URL that refers to a server running on localhost (as
part of the same app).

Yes, but implementing this proxy would require rooting the device.

Hmm an alternative would be implementing a filtering web proxy. Much

Is there any way, that I can create an application, that would use a

Is there any way to do what I want to do with API 8

My phone is supposed to be updatable to Gingerbread, but that brings me only

The WebView has it's own built-in JSON processing functions so no real need 
for an external javascript library.

var jsonObject=JSON.parse(jsonString);

Oddly enough, String [] is accepted as a parameter without problem,
just not a return value.
Feels a bit buggy or forgotten.

If you need to return something more complex, you could always generate a 
serialized JSON data structure from JS using your favorite library, return 
it as a string, and then parse the results using Android's JSONObject.

[Streets Of Boston]

I don't think it is supported.
In our code, we communicate arrays of data by plain Strings, calling 
'join()' on the JavaScript array and then parsing out the String into an 
array again on the Java side.

[rhansen]

Thanks for your anwsers,

@MathieuB
Yeah, this would be an option for testing but not for the final release. At 
least I will try that although its some effort.

@Streets Of Boston
Unfortunately the LogCat does not show anything suspicious. I have 
overriden almost all functions of WebView and WebChromeClient to see what's 
going on. I can see it starts downloading files and then simply stops in 
the middle.

@Pent
Absolutely. If something goes wrong it is pretty annoying to find out why. 
In this case I am pretty stuck completely. I am fighting with this since 
months. It must be up to something they have changed after Android 2.x, 
because it works without any error in Android 2.x. And the fact that Chrome 
for Android shows the same weird behavior it must be up to sth. they have 
changed in Android 3.x and Android 4.x.

Also, try set a WebChromeClient on the WebView and override
onConsoleMessage.

On the other hand, I've been working with WebView and JS for the last
few weeks and it's often annoyingly quiet when something goes wrong.

[android-developers] Re: WebView designMode doesn't work?

[Aerik Sylvan]

Another gentle bump.  Testing seems to show that design view sort of works 
- you can enter text, but no cursor shows which makes it almost impossible 
to navigate.  Also, selecting text and changing it does not work (though I 
read on stackoverflow that text selection is handled in a different android 
View so that it sort of understandable...)

[android-developers] Re: Webview masking onclick events

[mcterry]

that is interesting!  I can't say I've personally seen this issue.  You may 
want to make sure that the WebView container has the "focusable" attributes 
set to "true".
http://developer.android.com/reference/android/view/View.html#attr_android:focusable
 

Hope this helps!

You can use android WebView widget to load html
like this,

*WebViewObject.loadData("html string content");*

WebViewClient.onPageStarted() is the most reliable and does not depend on

[android-developers] Re: WebView Java script function

[Amit]

Thanks John for response.

With my response " It is not necessary to be same url as it being loaded 
from." I didn't mean variable url in  Moktarul's solution can contain wrong 
value. I was meant: for callback, this info is passed as string variable. 
This argument carries actual url value, if loaded page is written by us. 
But think of situation, any malicious page is getting loaded and page calls 
this exposed JS function. Malicious page writer may not intend to pass 
correct url information. 
I am looking for solution, if currently loaded url information can be 
retrieved inside JS callback from webkit/android SDK , then this info will 
be authentic.

I hope you understand the problem.

This is incorrect, *webkit* knows what url is authoritatively being loaded 
(not necessarily Android). The webkit/JS container bridge is synchronous 
while the communication between webkit and the various android callbacks 
are asynchronous for the most part. (i.e. In general, Moktarul's solution 
is correct if you want the currently loaded url (top level) from 
JavaScript).

[android-developers] Re: WebView Java script function

[Amit]

I think you code snippet has  currentUrl() as JS exposed function. Is there 
anyway to get urk infromation from android API. Android.currentUrl(url), 
caller can pass anystring. It is not necessary to be same url as it being 
loaded from.
But i think, if android API provides this infromation, it will be reliable 
information as   android known which url it is currently loading.

[android-developers] Re: webview resets when I change orientation

[Flowers]

Technically, the Activity is shutdown and a new Activity is started
for the new orientation.  You can prevent orientation changes
altogether as Kris stated.

If you do switch to a full Application instead of your Activity, you
may be able to store your state outside of your activity so when the
landscape view opens it can re-open the webview more or less how it
looked before.

[android-developers] Re: WebView problem with youtube video

[John Purcell]

Danielle,

If you look at the src (android-3.2.2_r2 is what I'm looking at), it's
crashing in the custom view. Unless you've implemented the code I
mentioned before, this will be the case.

[android-developers] Re: WebView problem with youtube video

[drenda]

Hi John,
thanks for your replay.
I'm usign Honeycomb on a tablet.
Unfortunally the order of the loading url don't resolve the problem.
I'm try with this code:

setContentView(R.layout.video);
final WebView webView = (WebView) findViewById(R.id.video_webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setPluginsEnabled(true);
webView.loadUrl(getString(R.string.urlYouTube));

You can test this simple code with some video on youtube and you
realize that you can see the preview image of the video but when you
click on play button the video don't start!! Moreover if you click on
maximise icon of the video the application crash as you can see here:

[android-developers] Re: WebView problem with youtube video

[John Purcell]

In general, the loading of the URL should come last (right now you've
got plugins and Javascript enabled messages being sent to the webcore
after you send a url request).

Is this on Honeycomb or ICS? (I'm guessing ICS due to the 'normal'
errors you posted above). Keep in mind that video needs special
handling in older versions of android (well, in all versions really).
http://code.google.com/p/html5webview/ will work for 2.x, but is out
of date for 3.x/4.x

You have to use loadData applied on webview and you can retrieve your

You might look at setCacheMode() on WebSettings, if caching seems to

[android-developers] Re: WebView ignore Javascript that invokes PUT/DELETE Http method

[Ori Harel]

Those are not part of Android, but the problem exist only in Android 
WebView.
Anyway, I solved it by forcing the WebView to ignore the cache by:


$.ajax({
type: methode,
url: 'some_url?d' + new Date().getTime(),
data: JSON.stringify(req),
  });

As you can see I added a new Date() object creation in order to overcome 
that caching mechanism.

Re: [android-developers] Re: WebView ignore Javascript that invokes PUT/DELETE Http method

[Mark Murphy]

AFAIK, $.ajax is not part of Android. It is part of some JavaScript
library that you are using (e.g., jQuery). Please ask the authors of
that library what the requirements are of the browser to support
PUT/DELETE operations.
