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.

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.

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.

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.

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?

I'm trying to tell a WebView to scale the page down to a certain percent. I've tried using setInitialScale() as that seems to be exactly what I want, but it seemed to have no effect.
Am I just missing something obvious?

I'm building a service that sends a broadcast intent when some value changes. The service sends the broadcast like this:
Intent broadcastIntent = new Intent(); broadcastIntent.setAction("nl.vu.contextframework.NEWREADING"); broadcastIntent.setData(Uri.parse("context://"+cer.getKey())); broadcastIntent.putExtra("reading",cer); broadcastIntent.addCategory("nl.vu.contextframework.CONTEXT"); sendBroadcast(broadcastIntent);
In some Activity (in a different process), I'm tryint to receive this broadcast as follows:
IntentFilter intentFilter = new IntentFilter();
intentFilter.addDataScheme("context");
intentFilter.addCategory(CATEGORY_CONTEXT);
registerReceiver(new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
Log.d(TAG,"Received intent "+intent); }
}, intentFilter);

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.

I want to generate a Listview that has some dividers between some of the entries, like it can be seen in some of the property sections. See the example below. I try to generate a List that consists of some textviews followed by one of the fancy dividers explaining the next part of the list and then again some text views. How can this be done? I thought about creating different views to add to the list? Is this the way to go?

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.

It means, that it has vertical headers (fixed horizontally), which can be scrolled vertically, and horizontal headers (fixed vertically), which can be scrolled horizontally. The contents should be scrollable both vertically and horizontally. To make it clear, I tried to 'draw' here...........

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?

I am trying to create a basic datasheet in my application using a TableLayout. The first row contains the titles of each column. Every row thereafter is data. I would like the data to be scrollable while keeping the first title row visible (i.e. the first row would not scroll with the rest).I have tried something like the following (unsuccessfully)

I'm getting some odd side effects when I set a header to my ListActivities. 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.

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?

I have a friend who is added to my Desire's contact list.
1. He is on my Facebook contact. (His facebook pic appears in my Desire contact list)
2. He is my Gmail contact as well.
3. He is added as a 'Phone Contact' as well.
I sent him a text few days ago but don't remember if it was using facebook or my phone (network provider sms) but now when I go in to 'Messages' and send him a message, I just can't figure out if I am sending him a message via Facebook or to his mobile number.

I am trying to get the images to have transparent backgrounds so the map is not blocked by a square marker with an image in it. What image editor and what settings should I use to get this to work?
I am trying to do some custom backgrounds for buttons and the same problem comes up: I get square corners and a background that does not scale with the buttons.
I think this all part of the same problem: I am not using the right tool with the right settings to create the images. I must be misinterpreting the documentation and examples that talk about a white border around the image and a black line along the top and left side for the expandable button background.
Here's a quick way to reproduce the problem:
Follow the directions to create the MapView program as described on:
http://developer.android.com/resources/tutorials/views/hello-mapview.html
For the icon I first used the image copied from the page:
Next I edited the picture in Microsoft Paint, and cut off the little guy's antennae. I'm not cruel and no real androids were harmed in that experiment. I surrounded the new picture with a pixel thick border of white, copied from the border that was around the rest of the image, and then copied the black that was there as well in the void areas of the image, outside the border.
I saved the image as myandroid.png and copied the file to the layout folder. Pointed the activity to the new pic and ran the program.
The image was displayed with a full square background and shadow, not the android shaped image and shadow that was there when the original image was used.
Custom Button background:
Follow the directions for the Relative Layout example at:
[url]
Next, I created an image to expand as a background for the button called backbutton.png. It too is surrounded by a white border and black filled on the corners, the top and one side per documentation I found in "Android Programming Tutorials" on page 298.
The background does not expand, nor do the corners round.
I wish I could show you screenies of what I have.
How do you create the images for the custom backgrounds and the images for the custom map markers and buttons? I need to know what image editor to use and the file attributes to set, so the images expand and display with the proper void spaces in them.

I'm creating my own View class, and defining custom xml attributes with a attrs.xml. As long as I provide each attribute manually, there is no problem, but
code:...................
The android:text is properly set in my instance, but the borderDrawable is not. I guess this has something to do with namespaces, because inside the styles.xml, the name="mypack:borderDrawable" is not handled by the XML parser's namespace facility, because its inside an attribute value. So "mypack" is in no way connected to "http://some.weird.url.com/seems/not/to/ matter" and adding it via xmlns:mypack... to the stylefile would not help, I guess. In the same file, "android:text" is somehow recognized, even though "android" is AFAIK only a ns-defintion for [url], which is also not declared in that file.
So what is the proper way to set a custom attribute in a style?
