Android :: Application Optimized For High DPI Screen But Supporting Only Small / Medium
Aug 18, 2010
I'm building a game with graphic assets in hdpi resolutions (hence I put the files in drawable-hdpi directory). I don't want to have a corresponding mdpi resolution of the images, and I will code everything in 240-dpi based pixel coordinates.
Is it possible to still allow mdpi and ldpi devices to run the application, by automatically scaling the graphics from the hdpi version? Optimize for high-dpi devices only but still support (small- and) medium-dpi screens.

Just got Camera 360 and I'm having some trouble on my EVO. I'm shooting in high quality and in 1280x960 resolution but when I download the pics to my laptop they are coming out 424x320. I bumped up the resolution and same thing, small pics. The stock camera is working fine shooting at 1280x768 resolution

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 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 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 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 nearing the end of a small project to develop an android app. As a first time developer, and a one-man band, I am anticipating selling it at a low price point. I have followed some of the discussions on the Android blog and elsewhere about licensing and obfuscation, and I am in two minds. Part of me thinks that I have spent a long time on the development, so why should I make it easy for people to pirate the app? The other part thinks that it could be fairly time consuming to implement licensing and obfuscation, stop people using the app from non-google supported countries and wondering how much of an issue it is anyway for a small app.
However, if you google even a small app and add .apk at the end the number of "warez" downloads is fairly shocking if it's true. Just wondering whether anyone has any opinions either way, about the impact of piracy on a small developer. I'm not expecting to make my fortune with this app, and would aim for I guess 1000 downloads or so. I may even release an ad-supported version some way down the line depending on how sales held up, which would solve most of the problem I guess.

What is the best approach to managing a small SQLite database private to the application? Open (getWritableDatabase)in OnStart and close in OnStop in each Activity?Open in OnCreate and keep open til the user quits the app (where would you put close?) Open, do work and close as soon as possible each time it is needed?

My project contains three drawable's folders: drawable-hdpi, drawable-mdpi and drawable. I build it with android:minSdkVersion="3". When it runs on Andriod 1.6 or higher it always uses images from drawable-mdpi on high density screens.
How to fix this?

The Android documentation says that best practices are to make two drawable directories - one for HDPI and one for MDPI. It also says that if the MDPI directory doesn't exist and a MDPI device is running the app, it will scale down the HDPI ones so everything looks good. Is there any reason not to just make one high resolution set of graphics? One con that I can think of is performance issues and one pro I can think of is only having one set of images for your app.

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?

There is an application called QVOD that downloads videos to a local cache on the Android device, and for many devices it works just fine. For many devices however. If the device is running ICS, frequently the playback features stuttering audio. I have found where QVOD saves the video files, although it separates them into several pieces, making it difficult to just browse to that directory and use an alternative player, such as MXPlayer. I have found that if you cat the files together into one RMV file, you can then watch it with another application and it plays just fine. That means the audio codec built into QVOD is almost certainly the problem.
What I'd like to do is build a simple graphical app that allows you to view the videos in that folder and automatically cat the files together so you can either save them or view them in another player. Having some background in programming, I understand the process flow of this is very simple. Unfortunately, I do not know how to program in java. Ideally, it would be great if the makers of QVOD addressed the problem directly, but having spoken with them on QQ, it doesn't seem they have any interest in doing so.
I don't see this program taking more than a hundred lines or so, and would be a great contribution to the Android community.The application will SURELY get a lot of attention, because it will not only allow those with audio problems to enjoy their videos, but it will allow those that aren't having problems viewing to at least save the files and also have a CHOICE of what application to view them in.

I just received my new Zopo ZP300+ Android phone with Android 4.0. When I downloaded a flip clock app from the Apps Store at Google Play it arrived on my screen so small I can hardly see it. This did not happen on my previous Androind phone by LG. How do I get the clock to show at the correct size?

Wondering if anyone knows the most optimized way to handle opening an URL in android. Here is how I am doing it:
String tempUrl = helper.getUrl(tempString);
Intent i = new Intent("android.intent.action.VIEW", Uri.parse("http://"+tempUrl));
startActivity(i);
Must you start a new activity in order to open a URL?

Started lastnight and AT&T doesn't seem to know what's up. I was fooling around with the AT&T Nav and the Google Nav when it happned. Not that I haven't mess with them before but I found it strange. Also got a small screen that popped up once when I went into applications saying Sim on/off with the choices to click ok or cancel. I'm baffled. Any help would be appreciated. Might just walk into AT&T for a replacement...

I upgraded (through tmobile) from a G1 (which I had since launch date, and loved until it just became too slow and all support ended) three weeks ago. I went to the tmobile store, and checked out the options. I LOVED the Vibrant, but I had some concerns over it's apparent "flimsieness"... the sales rep assured me that it only felt breakable, and that the Gorilla Glass screen and other features of the construction made it just as durable as all other phones. So, I got it.
I love it, still.
Thing is, last night, I picked it up off my desk, and it would not unlock. When I looked closer, I could see a small crack running under the screen. The phone has never been dropped, never been hit with any impact... nothing. It has never been out of my possession, never been water damaged... nothing. But, now, it has this cracked screen and won't unlock, won't do anything. Plus, now this morning it is showing a completely pink screen.
Of course, I know these (and all tiny little smartphones) are fragile. I have insurance for that very reason. If I break my phone, I am more than willing to pay the $130 through insurance to replace it. But, I do not feel like I (or anyone else, for that matter) broke this thing. The most impact it has had on the screen is button use on the touchscreen. If this thing is going to do this as a result of normal (actually, probably lighter-than-normal) use, I feel like it is insane for tmobile to expect me to pay for the claim. I do not think it is reasonable to ask a customer to pay $130 for a new phone 3 weeks into owning it, when it has not been damaged due to any human error or damage.
I had a Ghost Armor protector on it, and it was in a plastic protective shell, and it shows NO signs of damage beyond the messed up screen. I feel like that, coupled with the GPS thing (the awesome GPS was the second main selling point the sales rep spouted, after the Gorilla Glass screen!) and the fact that tmobile inexplicably removed my unlimited text option ("accidentally" according to them), should mean something to someone.
So, any ideas for options here? Is there ANY chance that I can tmobile's warranty people to regard this as a warranty issue and not an insurance issue? I do not want to be $400 into a new phone after just 3 weeks, especially with no solid GPS, no Froyo, and the other issues. I have been with tmobile for 5 years, and always justified it by their good customer service; so how can i get that customer care to work for ME now?

I just noticed this chip/scratch on my screen. It wasn't there yesterday. And nothing happened to my phone, so it's puzzling as to where it came from.
Especially since nothing "happened", I thought the screen was nearly impossible to scratch? Or in this case it's a bit chipped, so that may be the answer. Anyways, here's the picture.

I am a big fan of mythbusters and i'll bet that many of your are too. I like all those high speed camera shoots and i was thinking if would it be possible to make an app to use the camera to shoot high speed videos. I am not thinking like professional high speed video (those go up to millions of fps) but more like up to 1000 or 500. The desire should be able to shoot hd 720p video (lets hope with the next update) and may be would be possible to to make lower resolution high speed videos. I think the cpu is enough, but would the camera be able?

I just got my pair of UE600vi earbuds with a mic and in-line controller.
Everything works as expected (so no volume control), but what I didn't expect was that the built-in mic doesn't seem to work properly. When the cable is plugged in properly I get audio in a call, but the person on the other side of the line says he can't hear anything.. However, if I take the plug out a bit so that one black ring is out of the plug the mic seems to work,(probably because the mic is disabled and it uses the phone mic..) but I only get audio to one earbud.
I contacted Logitech which said that they can do nothing and that it's Android's problem.. However some people say that they've had no problems with apple-optimized headsets apart from the volume buttons.
