I want to make my app compatible to different screen sizes. I am right now developing on the Droid and need to know how can I import the screen image on eclipse emulator? I don't have a droid phone but want to make sure my app layout doesn't change on the Droid.

<supports-screens android:anyDensity="false" android:largeScreens="false" android:normalScreens="true" android:smallScreens="false" android:resizeable="false"></supports- screens>
first of all what is the resizeable attribute? It does not seem to be documented. This is working almost 90% for my game except when testing in WVGA screen resolution, all my images are scaled incorrectly, it is longer vertically than horizontally. I was expecting the screen compatibility to maintain aspect ratios as that of HVGA.
Also in my layout I have a scrollview and it is designed in such a way that in HVGA when it is not scrolled down, the items are hidden away, however now in WVGA those things are shown. If the aspect ratio of HVGA is maintained I won't have this issue. How can I make sure the aspect ratio is maintained? Also in my layout I am positioning some items using pixel positions. Should I convert these to dpi? How do I calculate what dpi they should be?
I'm getting ready to release my first application the marketplace. It's being written for devices running Android 1.5 and above, however there aren't any specific folders for the three different screen densities (I think those came around in 1.6). Should I make these folders myself? Where should I put image resources for the different densities and what should I put in my Manifest?
View 2 Replies View RelatedI am designing a home screen widget. I ran this widget on a HTC Hero device, which has a screen of 320 pixels * 480 pixels with mdpi. It ran perfect on HTC Hero. The widget takes 3 cells * 2 cells space, i.e. 240 pixels * 200 pixels.Then I ran this widget on a Nexus One device, which has a screen of 480 pixels * 800 pixels, mdpi. Since Nexus One also is mdpi, so I though 240dip is equivalent to 240 pixels on Nexus One and 200dip is equivalent to 200 pixels on Nexus One, so the widget will not take 3 cells * 2 cells space on Nexus One device. To my surprise, when running on Nexus One device, the widget take exact 3 cells * 2 cells, about 360 pixels * 300 pixels, on Nexus One device.I am confused. The layout xml above specifies 240dip in width and 200dip in height for the widget, but why did it take 360 pixels * 300 pixels on Nexus One Device? What am I missing?

View 1 Replies View RelatedFrom Android widget screen guidelines,we know that, home screen has 4*4 cells, and in portrait orientation, each cell is 80 pixels wide by 100 pixels tall. I think these are for baseline HVGA screen. How about for large screens and hdpi screens, do they still have 4*4 cells for widget and each cell in portrait orientation is still 80 pixels * 100 pixels?

View 3 Replies View RelatedI got to know that the devices with screen resolution 1280x720 or 720x1280 are extra large screen devices.
But when I run my application on Samsung Galaxy S3 SGH-T999 (resolution 720x1280) throught eclipse, the following code prints "Normal screen" i.e. it is a normal screen device but according to my knowledge it should print "Extra Large screen". If its a normal screen size device actually then why its picking the layout (XML) file from res/layout-xlarge-port folder instead of res/layout? Need to understand this screen size concept so that I can make my application for multiple screen sizes.
// get and check the screen size of the device
int screenSize = getResources().getConfiguration().screenLayout &
Configuration.SCREENLAYOUT_SIZE_MASK;
switch(screenSize) {
case Configuration.SCREENLAYOUT_SIZE_XLARGE:
Toast.makeText(this, "Extra Large screen",Toast.LENGTH_LONG).show();
break;
[code]...
how can I get the width and the height of the screen?
View 1 Replies View RelatedI have an app that I would like to keep 1.5 compatibility but support the additional display resolutions of more recent devices like the Droid. I've read the suggestions in the dev guide, specially the legacy applications section, since that's exactly what I want to do.I'm not running in compatbility mode, so anyDensity is set to true and all screen sizes are allowed in the manifest. I've recreated all my graphical elements so they don't get upscaled on a 480px-width screen (called "hires-bitmaps" in the following).If I put the hires-bitmaps into drawable-hdpi and leave the others in drawable, the emulator2.0 (WVGA854, density @ 240) displays them perfectly. On the other hand, the emulator1.5 (320x480, density @ 160) - and my HTC Hero - ALSO use the hires graphics in drawable-hdpi. That's a problem because the hires graphics scale slightly differently and I don't want the app to resize too much.As mentioned in the dev guide I can prevent this by adding the API version number to the resource folder. Not very convenient since I'd have to keep the hires bitmaps twice (drawable-hdpi-v4 and drawable-hdpi-v5), but I nevertheless tried it. Result: emulator2.0 uses low-res graphics from "drawable" (which is bad), emulator1.5 as well (which is good). And what's weird: emulator1.6 (WVGA854, density @ 240), uses hires-graphics. Now that seems odd.

View 2 Replies View RelatedI am trying to determine the physical size of a screen in inches.
Normally, I could do something like this:
CODE:.............
Then use metrics.widthPixels and metrics.heightPixels. Now that I know the width and height in pixels, I should be able to calculate size in inches if I know the density. Easy enough, metrics.xdpi and metrics.ydpi.
Then screen dimension in inches should be:
CODE:.................
Seems simple enough except that it doesn't work.
On a Motorola Droid, the system reports back: xdpi and ydpi as 96 (which cannot be true).
And the screen resolution as: 480 x 854. Which results in a width of 5" x 8.9" -- which as I'm holding this in my hand right now, I must say - cannot be correct. how to accurately calculate this?

I am trying to change the screen size of the emulator and see on the site that they tell you what commands to use, but it doesnt' tell you HOW to do it. how I would change the screen size. I believe this occurs on startup. I have eclipse as well, but would rather just shell into it and change it whenever I want.

View 1 Replies View RelatedTried to search for this one but the search terms I used didn't seem to find worthwhile results. I'm creating an application to run on a device with a 800x480 resolution (the archos 5) so I've created an AVD in the emulator with that resolution. However, when I run my program in the emulator it simply shows the program with the default android size, centered in the 800x480 window. It is not stretched to cover the whole screen. How can I fix this? I'm using Android 2.1.
