I have see some apps in Android that use some packages:
import android.net.http.EventHandler; import android.net.http.Headers; import android.net.http.RequestQueue; So some packages do not support the current version of SDK. Where can I find it? Would u tell me about it?

View 1 Replies View RelatedI 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?

View 3 Replies View RelatedIn 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?
We understand aapt has support only for small and numbers. Any reason for not supporting capital letters.. in future could we expect support for the same.
View 4 Replies View RelatedI'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?
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 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 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 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 created a list view in an activity and the list shows some fields.When we click a list item a custom dialog should pop up and the user can enter some new value to this field.The custom dialog contains one edit text and two buttons ok and cancel.It is working fine.But when my list is more that means if it exceeds screen size it is showing scroll.But when we select bottom items which we can select using scroll the dialog is appearing in normal fashion.But after entering new value if i am trying to save the application is getting crashed.

I'm writing an app, that has a somewhat modular system. It has a core app, and some apps, that consist of a single Service, that implements the desired interface. I followed the guide to create the IPC communication. But now I need to get all the services, installed on the system, that my core app can work with. How do I do this? I mean, is there any way to mark my Service apps with some kind of a tag, and then filter results, presented by the PackageManager#getInstalledPackages() based on that tag value? What's the common practice of doing so?

View 2 Replies View RelatedI've been trying to modify the native android applications downloaded from the android source repo at github. But I noticed that after creating Eclipse projects from some apps, like the Launcher, there are missing imports, variables that are not declared anywhere else, etc... After my initial research, I noticed that some of the libs that are native, are compiled at runtime and registered in the dalvik VM as java libs and by having done this the system finds these as already present libs, the same goes for the "phantom" variables. But I don't understand how does a developer open such a project in any java ide, and compile it. So what do Google developers use to work on android apps? I don't believe it's eclipse, since I am not sure you can make eclipse use runtime imports, and runtime variables. And I am almost certain that they do not write code in notepad.

What is the secure way to store passwords on android device?

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 am very new to android,i developed an sample web application and hosted it apk build file in different android version and on different sized devices,here i am getting problem in my design of layout such as listview not being displayed properly bottom portion is not displayed well and the align is not so good.

Its that little part of the icons(launchers) being able to have a slight perspective and looking through the requirements to design icons it seems i might be a lot faster using a 3d modelling package and then following part of the icons template guide(based from my requirement though!).
View 2 Replies View RelatedI have seen several applications that are free, but allow for add on packages to be installed. Gang Wars sells Respect Points Mafia sells Favors Dungeon Quest sells Gems The central game is a free app, but you purchase these add on apps for in-game benefit. Has anyone purchased one of these add on apps? What is the experience like? Do you have to leave the add on installed on your phone? How does this work technically? Do you think they set shared preferences? How would you handle the 24 hour uninstall rule? I am considering releasing a free game with 10 levels, but offering a full set of levels (say 25) as a separate paid app. I'm looking for the best way to accomplish this and thought the above might have some bearing.
