Android :: Supporting Multiple Screens - Document Contradict Itself
Jun 11, 2010
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 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.

I 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.

I 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 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.

Could it be possible to make each screen have a different wallpaper while scrolling? 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.

I 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.

I 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 the galaxy S5 running 4.2.2
I hate having the phone wake up in my pocket after unlocking with either fingerprint or pin.
The phone is set to lock after 5 minutes of inactivity - but if bumped in the pocket, the phone wakes up without the swipe lock screen.
Is it possible to use a combination of two lock screen types?

I currently have an app on the market that supports Android 1.5 (SDK level 3) and up. It also takes advantage of several features that are only present in Android 2.0 (SDK level 5) and up. I do this using Reflection.
I read a post on the Android Developer Blog that talks about how to support these new features while using no Reflection, which would be amazing. http://android-developers.blogspot.com/2010/07/how-to-have-your-cupcake-and-eat-it-too.html <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="5" />
I have tested this out and while it works there is one huge downfall. Currently if I try to add a SDK level 5 class, but I don't know that it's a SDK level 5 class, there is no worries. Eclipse isnt going to find the class and I'm not going to be able to add it.
Using Google's recommended method does allow me to add the classes and gives me no notification that this code is targeted just to SDK level 5 users. This opens up too big of a possibility of adding in code that would break some users without knowing.
Does anyone know of any plugins, options, etc that would warn me at the places I have targeted SDK level 5 to keep this from happening?

When we try to implement orientation in AP layer, we can set "android:screenOrientation" parameter in AndroidManifest.xml file or call "setRequestOrientation()" method of Activity class. But if I want to porting android in new HW device, how can I do? Do I need to modify the graphic driver, or just add configuration in program. (Actually I do some experiments but my AP cannot rotate) Besides, can every experts tell me when I set the "android:screenOrientation" parameter, which process will read this configuration, pass to where and which process will do the rotation?

I am working on an Android application which is supposed to play videos over HTTP on Android devices. Before we setup a server to host the video files just wanted a few things clarified: As per the developer documentation, Android supports .mp4 and .3gp container formats for video. If we use H.263(video) - AAC LC (Audio) audio-video codec used for our media files will we be able to play the video by passing the URL to MediaPlayer class?
I did a little experiment and passed URL of one of the video files(.mp4) to the MediaPlayer class and got the following error:
Command PLAYER_INIT completed with an
error or info
PVMFErrContentInvalidForProgressivePlayback
From the docs, I came to know that for progressive playback, the video's index (e.g moov atom) should be at the start of the file. Questions:
1. How do we make our videos Android-ready?
2. What are the different considerations that we need to make?

I have just started with Android development and bought a handset(HTC Hero) for test and usage purposes. The sad part is that it doesn't display one of the scripts (Devanagari to be precise). Hence, I would like to contribute to the Android project to help render it. However, since I have just started I have no ideas of where to look for and begin with !
To be very precise, I would like to contribute for proper rendering of Nepali Language (Devanagari Script) for the Android OS. For ex. I would like to be able to see the following in an Android device rendered properly......................

I am a fresh developer on Googles Android Platform - my HTC Desire arrived last week. Now i need a way to sign in to my existing application (Java, currently running on jetty). The server Application is developed using spring security 3.0.2
In my case, i want to support the following: If a user has set up his Android phone with a googlemail/google-Account (and most users do) i want to use this account credentials to automagically log in to my server app.
Is there any Android framework supporting that use-case? Or are there any alternatives? I read: http code.google.com intl/de-DE/apis/accounts/docs/OpenID.html
How we do sign in with an app on google AppEnging is described here: http://blog.notdot.net/2010/05/Authenticating-against-App-Engine-from-an-Android-app
