Android Webview how do you set it to be 100% zoomed in?

I'm using Anddown to convert some markdown text to html and I want to display the html in a webview. The webview is part of a fragment that takes up around half the screen on a tablet in landscape.
I want the html to appear at 'normal' scale, as in I never want it zoomed out so you can see the whole page. Most of the time this is fine since text in blocks wraps when it reaches the end of the view. But some of the markdown elements result in an html element which stretches the view horizontally, so I've got something that looks like this:
----
----
----
--------------
----
(imagine the dashes are text, the short lines are wrapping correctly to the fragment width)
When I load that to the webview, the page is zoomed out fully so that that long horizontal line fits the width of my view. I don't want this, I want the webview to always be zoomed in. The weird thing is that sometimes when I load the html to the webview, it will automatically zoom in to what I want (but with some horizontal overflow). This doesn't happen every time and when it does, I can see the zoomed out version for a split second before it resizes.
So my question is, how do I get it to default to 'zoomed in' always? I don't care if it means there's some horizontal overflow, I just want the text to be 100% in scale (if that even makes sense).

For normal scale you should use this viewport tag (on your html's header):
<meta name="viewport" content="initial-scale=1, maximum-scale=1,minimum-scale=1">
Now, if you want different scale you can change these settings (for example use a scale of 2)
Hope that answers your qauestion

If you're using text.
Have you tried using
word-wrap:break-word;
So the text won't be outside it's parent

Full Height site on Android table (Nexus)

I'm trying to get the height of the Nexus tablet using $(window).height(); but I'm having troubles as it seems to add the height of the URL bar to the result, which disappears when the user is scrolling.
My page has different sections and each one should look like a full screen page.
The first page looks good until I start scrolling down, as the URL bar disappears and the visible area increases.
I've tried (without success) to hide the URL bar using the techniques explained in this post, but I can't control it.
Is there any way to deal with this problem?
Thanks.

I came with the conclusion that the best option is to avoid the hiding of the URL bar for the Nexus.
This way the calculated size will always fill the screen even on scrolling.
In order to do so I disabled the scrolling on the html and body elements and used and auto scrolling which scrolls from one to the next section using jQuery.

How to get WebView to wrap an image exactly

I am using a WebView to display some maps in my app using the Google Static Maps API. However, when I load a map into my WebView, it's always either zoomed out too far (showing a massive amount of white space around the map) or too close (showing only part of the map). Given that I'm requesting a map of the same size as the size of my WebView, I should be able to "tightly" wrap with no issues, but I'm not sure how to achieve that.
I've tried just running at the default settings, and that results in the map being zoomed in too far (and scrollbars being displayed). I've also tried this:
mapView.getSettings().setLoadWithOverviewMode(true);
mapView.getSettings().setUseWideViewPort(true);
which just results in the page being fully zoomed out. Are there other alternatives I'm missing other than futzing around with the scale?

I had similar problem with the whitespace. What I did was to go into the CSS file for the WebView and edited the margin/padding on the image I was displaying to be negative (I just edited until I was happy) so it would display completely in the upper left corner.
Then I set the height and width of the webView in my Android XML file until I was happy with the result. However I was having a bit of a problem with the width showing some white space on some devices but the height was good once I had found the right value.
My solution to this was to try to set the width as the same as the height in the java.class file for the activity but I was not successful, maybe you will have more luck.
In the end I abandoned the webView for my project so I can't really give you any working code.

Android WebView flicker after calling clearView()

I use a android.webkit.WebView to display some HTML formatted info to the user. Whenever I "page" in my application, I reuse all the graphical elements on screen and just fill them with different content. A WebView will by default increase its size to fit the contents, but won't decrease if the content shrinks.
To fix this, I call webView.clearView() to clear the view and then webView.loadDataWithBaseURL(null, html, "text/html", "utf-8", null)to reload it with data. It works, but it creates a very strange behavior where the view starts to flicker persistently. The flickering area seems to be the same size as what would have been left empty after filling it with smaller content.
I can't describe this better with words, so I created a short video to illustrate the problem:
http://www.youtube.com/watch?v=yL7tQpRSFe0
The WebView is the yellow box on the lower part of the screen.
Am I doing something wrong, or is it a bug?
If this is an Android bug, is there a better way to resize the view as to circumvent this problem?

'display: table' makes div display smaller on Android device

I'm working on a project where I have a stationary bar (to become nav bar), and then directly below it is a rectangle which is setup so that when you click it, it flips over. The width of both the nav and the flipping div are supposed to be the exact same, and they are when viewed in FF, Chrome, Safari, IE...but when I just checked it in the Android browser, the flipping div is about 10 px less in width than the nav bar. I've narrowed this down to the fact that I'm using 'display: table' in the div 'outerContainer' to vertically and horizontally center the contents of 'innerContainer' (which is set to be display: table-cell). This is an example of how I currently have it setup, which displays correctly in all browsers but the width of the flipping box is less in Android browser: http://jsfiddle.net/adRP4/9/
As soon as I remove the 'display:table' from .outerContainer, it displays in the Android browser at the proper width, however the content is no longer centered as I want it. This example shows the display: table removed will the proper width displaying, but the content not centered as I want it: http://jsfiddle.net/adRP4/10/
The vertical/horizontal centering method I used is based on: http://www.andy-howard.com/verticalAndHorizontalAlignment/index.html (similar to http://css-tricks.com/vertically-center-multi-lined-text/) ... when I tried changing it to the method outlined her: http://css-tricks.com/centering-in-the-unknown/ I ran into all kinds of problems...
Any suggestions on how to fix this?
UPDATE (6/28)--I discovered that when I check an iPhone, I have the exact same width mismatch as in the Android browser..
Thanks,
Mark

I'd suggest to use a DIV for the flip, and then, adding a div filling the flip and set as TABLE.
Or I suggest using the floater in the method 3 here : http://blog.themeforest.net/tutorials/vertical-centering-with-css/
