I have developed an application which en-composes list views and posted that .apk file in my htc device, the design and alignment everything works fine,but the problem When i am testing in various devices such as Morotolo Droid,Nexus Devices the alignment of Listviews goes wrong, so i planned to use the Layout folder as layout-hdpi,layout-ldpi, and layout-mdpi, for that i changed my manifest file as
<supports-screens android:largeScreens="true"
android:normalScreens="true" android:smallScreens="true"
android:anyDensity="true" />
Is it right putting android:anyDensity="true",also i used dp instead of dip. I went through this url, but still am not able to get a clear idea in this
http://developer.android.com/guide/practices/screens_support.html. so friends pls tell me(help me) to get clear idea in this and tell what mistakes i have doing. This is my main page xml code frnds.

In the Supporting Multiple Screens document in the Android Dev Guide, some example screen configurations are given. One of them states that the small-ldpi designation is given to QVGA (240x320) screens with a physical size of 2.6"-3.0". According to this DPI calculator, a 2.8" QVGA display equates to 143 dpi. However, further down the page the document explicitly states that all screens over 140 dpi are considered "medium" density.
So which is it, ldpi or mdpi? Is this a mistake? Does anyone know what the HTC Tattoo or similar device actually reports? I don't have access to any devices like this.
Also, with the recent publishing of this document, I'm glad to see we finally have an explicit statement of the exact DPI ranges of the three density categories. But why haven't we been given the same for the small, medium, and large screen size categories? I'd like to know the exact ranges for all these.
I have read the topic about supporting multiple screen size as well as different DPI. I am wondering which of the following way is better in supporting multiple screens:
1. Have different layout for different screen size (stretch the images)
2. Have different set of graphics for different screen (use the same layout)
3. Have different set of graphics and different set of layout for each of the screen
Which way is the easiest? And which way is the most optical way to design? Or is there another better way?
I've read the article "Supporting Multiple Screen" on Android developers site. But that doesn't apply to game logic.Let me get straight to the point. My situation is as follows:
- I'm creating a game using LunarLander code as a base.
- In my game, there'll be an object flying up from the bottom of the screen. The object will fly in projectile motion.
- I set the starting velocity, gravity and angle so that the highest point(of projectile motion) is almost at the top of the screen.
- The screen tested is Motorola Milestone. (480x854 resolution) Meaning the object travels around 854 pixels vertically.
I'm thinking of adjusting starting velocity based on screensizes. But that sounds unreliable when we've so many devices/resolutions out there. How do you combat these kind of problem when making games?
My application will have two layouts, one for large screens and one for normal. For testing I'm working with one phone (800x480 240dpi) and one tablet (1024x600 240dpi) but both are detected as large screen hdpi and long aspect ratio, so I'm not able to assign different layouts.
The only approach I think that can work is to create layout-large and layout-normal, get the resolution and programmatically set the layout folder. Is that possible?
I returned my HTC hero after a week because it had a dead pixel, but I also noticed dust under the lower portion of the screen right above the buttons on bottom. I use a otterbox commuter case while has covers for the dock and head phone jack, so Im assuming the dust came in between the buttons and the bottom of the screen.
View 1 Replies View RelatedI have had several emails from people with HTC Tattoo devices who say they cannot find my app in the Market.
After reading this page (http://d.android.com/guide/practices/ screens_support.html) I believe I have to add the <supports-screens> tag to my manifest file. However, when I try to do this I am confronted with "Error no resource identifier found for attriute support-screens in package 'android'" messages. What does one have to do to update their manifest to tell the market an app supports all screen sizes?
Furthermore, if I need to change the android:minSdkVersion from "3" to something higher or add the android:targetSdkVersion tag, will this prevent people with older versions of Android from using my application?
I've read the Android documentation:
http://developer.android.com/guide/practices/screens_support.html
but still have some questions. I'm trying to design a music application which basically has images of the instrument (ImageButton) that play a sound when clicked. However, I'm confused about how to have the ImageButtons scale to fit all the different screen sizes and how to position them.
Which layout is best used for needing to position ImageButtons in specific locations on the screen? (i.e. cymbals on a drum set) FrameLayout, RelativeLayout? If I only really care about medium and large screens, do I need to create different resources (images) for both as well as a different XML layout to position them? I'm trying to find the simplest way to do this without having to create a separate layout XML file for positioning/size and separate image resources for each screen.
How can we resize our application for different screens on different Android devices?

I can long press any of the top two rows apps/widgets fine to remove or add in an empty space. but the bottom two rows I can't remove or add with a long press.anyone else have this issue? I'm trying to figure out whats new but she isn't that into her phone so she never installs stuff on it, im the one tweaking and playing with her phone and I haven't touched it in a week this started happening randomly 2 days ago.
View 10 Replies View RelatedSo I searched the forum but no results to what I want to know. After setting up my new D2, the phone has listed some, actually all, of my contacts multiple times. Each contact is listed 4 times, and it's really annoying having to scroll through 400 people when there really should only be around 100. I haven't been able to find any of the contact management options that my old D1 had, ie filters and stuff. Can anyone point me in the right direction?
View 2 Replies View RelatedI am getting my feet wet developing software for the Android. My test app will have multiple screens (each having their own layout file). The main screen will direct the user to view the other screens based on user input. I kinda see this as layers of cake. Bottom layer being main; then you add and remove layers as the user makes UI inputs. The crazy trouble is how to view a second layer. I have created a second class which has its own onCreate method, which has its on setContentView(R.layout.secondlayer).
This class extends Activity much like my primary class does. I have a click event on a button within the main layout. This button will instantiate the new second layer class which I have done. And that is where my story endsI don't know what to do from this point. This is surely a newbie question If someone has an example that would be extremely helpful teach me to fish and I will be on my way.
I need a textview with multiple drawables at bottom. In android, I know that there is a possibility of giving one image drawable for bottom. But i need multiple to be drawable at bottom.
View 2 Replies View RelatedI am working on an application where I wish to have multiple screens (each of full display size) attached to each other horizontally, and switch between them by using the finger (swipe right / swipe left). The home screen does exactly what I want, but its implementation seems to be more complex than I thought. What would be your preferred way to achieve this functionality? Is there any Layout or View that I could reuse? More generally, it should work with the 1.5 SDK, so the gesture interface is not available.

I mean, taking as an example a case with three screens, it will be necessary to set a x3 screen width wallpaper to fit 1/3 on each screen, or directly setting different images for each screen. so the scrolling make it visually a different wallpaper on each screen rather than sliding the wallpaper a 50% each side.
View 2 Replies View RelatedI am working on an Android project where a group of buttons needs to show on the bottom of every screen (activity) in the application. The group of buttons are basically a navigation bar. I want to know the best way to do this without creating new buttons for every activity. I have been around programming (C++/C#) for many years but am pretty new to Android and Java so if someone can point me in a general direction.
View 2 Replies View RelatedI am trying to develop an application for which I want multiple screen support. I have read the Android article on Best practices for Multiple Screen Support. As per the article we have to follow 3 important things
1. Mention support for different screen sizes(large, medium and small) and any density in AndroidManifest.xml.
2. Place images of 3 dpi's (120, 160, 240) in 3 folders res/ldpi, res/mdpi and res/hdpi.
3. In layout's the dimension should be mentioned in "dip" units. Then Android will take care of the scaling on its own.
I have implemented all these points in my project. The images are picked up correctly from the appropriate folders. But the arrangements of the controls in not same.
e.g. I ran the app on three emulators
1. Resolution 240*320 dpi 120.
2. Resolution 240*320 dpi 160.
3. Resolution 240*320 dpi 240.
(All the emulator have same resolution but different density.)
The problem is the position of the controls is not same on all the three emulator. As per my understanding if the android:layout_marginLeft and android:layout_marginTop are mentioned in "dip" then this problem should not occur. As the density of the emulator increases the controls get placed more towards the right. Is it absolutely necessary that I provide layouts for all combination's of screen dimension and density even if the layout is same for all the devices?

I have a question about the way the Android market handles purchased apps.I've seen in other posts where if you upgrade to a new phone, your purchased apps will follow you.But how about if you use more than one Android device? For instance, later this year I may get an Android tablet. Presumably the apps I purchased on my Droid will downloadable on the tablet. But will they remain downloadable on my Droid? And if I purchase an app on the tablet, will it also be downloadable on my Droid?It seems to me that if the apps are associated with your account, then you should be able to download them on multiple devices.I was just wondering if anyone has actually tried and confirmed this.

Eventually I'm going to develop a multiplayer Bluetooth Game.Currently I've adapted Android's sample app BluetoothChat to connect my three Nexxus One phones.1 connects to 2 who connects to 3.1 sends its messages successfully to 2. 3 sends its messages successfully to 2 as well. 2 can send its messages successfully to 1 and 3, as it shares a ConnectedThread with both. But I can't figure out.how to handle getting communication from 1 to 3. Does anyone have any examples of communication between multiple devices or has done this themselves?

Is there any plan to increase the number of Exchange type accounts on HTC Android devices. Maybe in the new Sense Updates? Why did HTC not implement the code included in the stock Androind mail app (since at least 2.1), or at lease leave it alone! Since Hotmail has improved it's service to offer an Exchange style connection option there is a real day to day need to have at least two Exchange accounts on one device. I have been using the stock 2.2 android email client for some time and although it feeds into the unified calender app it does not feed into the Sense contacts ribon etc., I also goes high CPU at times (file conflict?) so is not a suitable workaround. And no I do not wish to use a third party app such as countdown, I like that with HTC's Sense system all things feed into a common thread - third party apps I have found have their own databases for email & calender etc. which I do not want.

I really dont have the money to test on "multiple" devices, nor do I know anyone with an older phone that I could ask for help that would possibly get any kind of bug. Not to mention, when I do get a bug report, how would I go about fixing it for that particular phone without having to buy it to make sure it actually gets fixed, or that the person didnt just came across a one-time freakish accident of a glitch?
