Android :: Porting SDK For Large Screen Devices
Sep 23, 2009
I am not sure, if this is the correct platform to talk about it, however I would like to know something about 'How Android supports the large screen display'. I mean here that suppose I want to port the Android SDK to a large portable device having a large display as compared to HTC G1 mobile screen, what all the OS modules (e.g surface manager, kernel: display driver etc) I need to look upon/modify.I guess what I am asking here is not a new subject as I can already see by below links that the Android OS is ported for large screen devices.
1. http://www.icpdas-usa.com/vp_23a1.html Specifications & Additional Information Models VP-23A1 VP-25A1 System Software OS Android 1.5 SDK Provided Standard ViewPAC SDK for Windows and Linux by GNU C language CPU Module CPU PXA270 or compatible (32-bit and 520 MHz) SRAM 128 MB
2. ARCHOS 5 Internet tablet shown on http://www.marketwatch.com/story/archos-brings-the-android platform-t... and on http://www.archos.com/products/imt/index.html?country=in〈=en as.
Let me know your opinion about it, any kind of clue will be appreciated.

I'd like to test an application on a variety of screen configurations so I know that it'll work (and the layouts will look right) on tablets and other oddly sized devices.

From 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?

I have layout issues in my application on Samsung Galaxy Tab. It has a 7" TFT display with 1024x600 resolution.
Galaxy Tab prefers images in "res/drawable-hdpi" to the ones in "res/ drawable". That is understandable. However resources in "res/layout" are used instead of the ones in "res/ layout-large". Does it have a logical explanation? Or what am I doing wrong?
What is a large screen for Android?

I am trying to get a slide down animation to work, and it seems to work except that it starts with a big black screen instead of the screen that was there. So I have layout1 and layout2. When I start the animation using ViewFlipper.showNext it puts a big black background over layout1 and then slides in layout2. If I use ViewFlipper.startFlipping() it slides in layout2 out as it is sliding in layout1 -- which is what I would expect.
My slide_down.xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromYDelta="0" android:toYDelta="100%"
android:duration="4000" android:detachWallpaper="true"/> </set>
My java code looks like this:
ViewFlipper vf = (ViewFlipper) findViewById(R.id.DropDownList);
vf.setAnimation(AnimationUtils.loadAnimation(this, R.anim.slide_down));
vf.showNext(); or vf.startFlipping();

I am trying to detect if the screen size is normal, large or small. I am using
Configuration conf =view.getResources().getConfiguration();
(conf.screenLayout&Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_NORMAL
When testing with the emulator this works for screen sizes normal and small, but large (480x800 & 480x854) returns that it is normal...
I have found very little information on using the configuration to detect the group, has anyone got any experience with this?

I am trying to create an activity layout that has a top level vertical linear layout like so:
CODE:................
This works ok as long as the wordDefinition text isn't very long. But, when I set the text to something very long, it pushes the back button off the bottom of the screen. Why? Isn't the ScrollView supposed to scroll the text in the child TextView?
I've tried playing with weights (e.g., giving the top text view a weight of .2, the scroll view a weight of .7 and the button a weight of .1, but to no avail.

In Javascript/jQuery, how can I detect if the client device has a mouse?
I've got a site that slides up a little info panel when the user hovers their mouse over an item. I'm using jQuery.hoverIntent to detect the hover, but this obviously doesn't work on touchscreen devices like iPhone/iPad/Android. So on those devices I'd like to revert to tap to show the info panel.

How does Android handle scaling of a video being played within a VideoView?
So for example if I have a video that is say 480 X 270 (width and height), aspect ratio 16:9. And, say the VideoView is added to a LinearLayout with LayoutParams of (480, 270). What will be width and height of the rendered video in portrait orientation in a device that is 320 X 480? In landscape? In another device that is 320 X 550?

I'm doing something like the following:Bitmap mBitmap;mBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.myimage);In onDraw I'm doing this:canvas.drawBitmap(mBitmap,0,0,null);My Manifest looks like this:<supports-screens android:smallScreens="false" android:normalScreens="true" android:largeScreens="true" android:anyDensity="false" /On Larger screens, my images shrink down to about a quarter the size of the large screen and sit in the upper left hand corner.For the life of me, I cannot figure out how to get my images and screen coordinates to automatically adjust to the larger screens.

I have to say that an user profile is a must have feature in an education. So no devices under android 4.2 aren't possible, because there must be an option to use "student profile" in a device to prevent any installation from an user.
1) If i have several devices (like 50 Android devices, Android 4.2 or later), what is the easiest way to manage them all at the same time?
- wifi?
- sync application for this?
- administration profile?
2) Do I have to make an account for each devices in GooglePlay or can I add them all under one account?How can i buy and install apps for each devices?
3) And does the Allshare offer sharing a screen with several devices?
How to manage several devices easiest wat - administration, installing/deleting apps, emptying devices (for example photos/videos...)...Or is it just better to choose iPad with a sync case? Im more interested in Android tablets because they offer much more for less money (example Galaxy Note serie). But I have no idea how to manage them all at the same time.

I am developing my am on mac (10.5.8), on eclipse and SDK 1.6 and a Vodafone HTC Magic Everything was working ok up to a few days ago. I can not see my device on adb devices. I also got a Sony Xperia and I can not see it on the list either. I upgraded the phone software (the HTC) to 1.6 a few days ago. Maybe that is what caused the change, but I could not be sure.

I'm spending considerable time in making my UI to work with keyboard input only. But in the end I'm not sure are there any android devices which don't have touch screen? The last problem manifests in PreferenceActivity, where I can't find a way to select Views in my custom Preference only by keyboard.

I read the official document about supporting multiple screens http://developer.android.com/guide/practices/screens_support.html
According to that document, I should just create different directories for different resolultion.
Now the question. How to support devices with normal screen and high density or low density?
I ask it because, there are two posibilities (WVGA800 (480x800) and WVGA854 (480x854)) and (WQVGA400 (240x400) and WQVGA432 (240x432)) and I don't know where to store some background images for them.
I would take drawable-normal-hdpi or drawable-normal-ldpi, but how to make difference between 480x800 and 480x854 or between 240x400 and 240x432?!
