Android :: Possible To Set Custom HTTP Headers In WebView?

Jan 5, 2010

I have to access a web page from within my application and, in order to have access to it, I need to set some custom HTTP headers. I want to use the WebViewclass in my activity but, as far as I can tell, it's not possible to set custom HTTP headers.

So is there a way of using the existing web browser (or WebView) with custom HTTP headers? My application targets Android 1.6.

Android :: Access Http Response Headers In WebView?

Jun 28, 2010

Is there a way to view the http response headers in an Activity once a web page has been loaded in a WebView? Seems like this should be possible, but I can't find any methods that expose the headers.

Android :: Sending Custom Headers In WebView

Mar 12, 2010

I've found some information about this topic, but I was curious as to whether anyone has had any success loading webpages in a WebView with custom headers. There doesn't seem to be any simple way of doing this. I've seen an implementation that involved downloading the webpage and separately loading the data into the WebView. While this is not difficult, the WebView then demonstrated problems with relative URLs and downloading images.

Android :: Load HTML File To WebView With Custom CSS

Nov 6, 2010

I have a WebView on my Android application which loads (WebView.loadUrl()) different local HTML files from phone's internal storage. I would like to include some custom css styles for them, Now, I could have my app edit every HTML file and add linking reference for the CSS file.I could also read the file contents, add the CSS linking and use WebView.loadData() to load it.But is it possible to do this a lot simpler and efficiently.Note: The HTML files are downloaded from a website. So editing them manually is not possible in this case, but once downloaded they can be edited via the app if necessary.

Android :: Custom Protocol Handler For Urls In Webview

Nov 6, 2010

I am hoping to create my own protocol handler for urls in a webview. I have tried two approaches already. The first was to attempt something similar to the approach defined here to create a customer protocol handler. http://java.sun.com/developer /onlineTraining/ protocol handlers / This works in a command-line Java program if I correctly set the system property java.protocol.handler.pkgs, but it does not work in Android, probably because I cannot figure out where to define this system property. Defining the system property in the code does not work. I assume this is because it needs to be loaded when the application first starts. I have also attempted to use URL.setURLStreamHandlerFactory. This works for creating URL objects within the code, but it does not seem to be associated with the WebView. Any ideas on how to get this working?

Android :: App To Download Only Email Headers

Feb 13, 2010

I'm looking for an app to download only the email headers with (or without, but better with) the possibility to download the whole mail.

The reason is to be able to take a quick look to all af them, avoiding wasting time of downloading when some friend has just the happy idea of sending you a heavy power point, or the pictures from your last party, or just simple spam.

I must say that there's another not less important reason: I don't have a 3G flat rate.

Android :: Best Practice For Static Headers And Footers

Apr 11, 2009

I am trying to display a high score table in my application and wanted to know the Best Practice for displaying static headers or footers. The data for the High Score tableis a REST web service returing up to 100 JSON records. I have looked at some of the previous posts http://groups.google.com/group/android-developers/browse_thread/threa. that talk about addHeaderView() & addFooterView() but they all seem to indicate that the footer or header will scroll off the screen. My 1st question is has someone been able to implement this in a clean way to allow a basic static header or footer. My second question is is their another way I could accomplish my goal of displaying my high score table besides a List View. I will be displaying 6 columns of data which will need to scroll vertically.

Android :: Adding Section Headers For My ListView

Sep 6, 2010

I'm adding section headers for my listView, there are few methods on the web. Since I'm using simpleCursorAdapter to manage my listView, I adopted phil bogle's method. http://thebogles.com/blog/2010/02/section-headers-for-android-listviews/

The error occurred at this part of the code:

CODE:.................

This is the LogCat shows how they compare while I scroll up the list:

CODE:..............

The correct output should be:
Sun, 05 Sep 2010
112
120

But when I scroll up, the setViewValue calls 120 first and compare with preDate(show above), it becomes:
Sun, 05 Sep 2010
112
Sun, 05 Sep 2010
120

So how can I make the section headers fixed after creating the headers? Why setViewBinder been called while scrolling?

Android :: ListActivity And Headers Giving Odd Side Effect

The ListActivity actually allows you to scroll up "behind" the header and click...which sends my app into a fit of errors b/c my Lists are connected to a Cursor and selecting behind the header returns a value of -1. Ive noticed this doesnt happen to any of my Lists that dont have headers.

Android :: Adjust Height Of Group Headers In An ExpandableListView Dynamically?

Oct 7, 2010

I have an ExpandableListView (ELV) with the groups having LinearLayout. I have set the height of the group to some value (38dip in this case, equivalent to two lines of text). If the group heading is long and would take more than 2 lines, it is not shown properly in the ELV item - some part of the view gets scrolled. On the other hand, if I change android:layout_height to "wrap_content" in the LinearLayout, the groups always show all the lines. But the line widths are variable, i.e., short titles show up with only 1 line and long titles show up with 2, 3 or 4 lines. That looks ugly. I would like to implement the height to be something like max("38dip", "wrap_content"). Is there a way to do this?

Even programmatically, I do not seem to be getting the actual height of the group if I set android:layout_height to "wrap_content". Any suggestions there?

Android :: HTTP Get Methods?

May 14, 2010

I have written a number of applications for blackberry and am just starting in Android. It seems to me that android has a lot more built in functions. I am starting by recreating some of my BB apps on Android and on one I take a few xml sites and parse them out. On blackberry I implemented this by creating a class that extended a thread. I would construct a new instance of this class with the parameters of my http request and it would call a function back in my main class, sending it the results. I am tempted to reuse my code, but am curious if android has something better built in. I have been looking at the handler class as well as possible using a service.

Bascially, I would like to start a new thread that will return a document of a specific url.

Android :: Simultaneous Http Requests

Jan 13, 2010

Is there a limit on the number of simultaneous http requests of the form:

HttpResponse response = client.execute(request);

I'm interested in any official limit as well as practical ones.

(In a previous life, you had to dig deep to discover that WinMo only allowed three WebRequests to be open at a time.)

Let's say I have a list of 20 files to download on a background thread.

Should I: Download them one at a time, blocking the thread (but not the UI thread) to wait for each one? Start 20 threads each downloading one of the files?

I expect the answer may be somewhere in between, where I create C threads and work on the queue of N files, where C is a number like 3 or 4.

I suspect some of you here have already done some experimentation and know the magic number. In addition, I suspect there may be more efficient ways of doing what I'm doing than creating a new DefaultHttpClient for each request.

Android :: OpenCore / Streaming MP3 Over HTTP?

May 12, 2010

Im experiencing an intermittent and very frustrating issue with MediaPlayer on Android when streaming MP3 over HTTP. Ive done as much research and debugging as I possibly can to try and find a solution, but am coming up short. I cant find reference to this issue anywhere, including b.android.com. Essentially, whats happening is MediaPlayer will not come out of the preparing state. The device is receiving audio data during this time, as indicated by network sniffs and the MediaPlayer buffering callback being invoked repeatedly with increasing percentage values, but eventually the buffer appears to become full and stops receiving. Because prepare() never returns, or more accurately when prepareAsync() is used and the onPrepared callback is never invoked, and neither the onError() nor onInfo() callbacks are invoked, the application can neither call MediaPlayer.start() nor make any sort of recovery. Other notable observations: The problem is intermittent, meaning that subsequent attempts to play the exact same MP3 stream from the exact same server may exhibit this behavior or not - The problem seems to be exasperated when the device is connected via 3G versus wifi - The problem occurs on different MP3s encoded by different software - The problem occurs when streaming from different HTTP servers - The problem cannot be reproduced on any of the Android SDK emulators - The problem can be reproduced on the HTC Incredible, Verizon Motorola DROID, and HTC Touch - When MediaPlayer successfully returns from the preparing state, there is an info message (what=1, extra=44) received. This info message is not received during the problematic case. Anyone ever experienced this, or even find a solution?

Android :: Retrying Http Connection

Oct 14, 2010

I'm making an http request. I'm on a platform (android) where network operations often fail because the network connection might not be immediately available. Therefore I'd like to try the same connection N times before completely failing. Was thinking of something like this:

DefaultHttpClient mHttp = ...;
public HttpResponse runHttpRequest(HttpRequestBase httpRequest)
throws IOException
IOException last = null;
for (int attempt = 0; attempt < 3; attempt++) {
try {
HttpResponse response = mHttpClient.execute(httpRequest);
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == 200) {
return response }
} catch (IOException e) {
httpRequest.abort();
last = e;
throw last;

I'm mostly worried about the connection being in some state which is invalid on subsequent retries. In other words, do I need to completely recreate 'httpRequest', should I avoid calling httpRequest.abort() in the catch block, and only call it in the final failure?
