[android-developers] Can I update an apk over the air programatically ?
Hi, I have an application I wrote for Android (lat's call it MyMainApp). My contractor wants me to write another utility (service) to periodically check his website for newer versions of MyMainApp, and if there is one - download it and install. I know this is handled by the Market app, but my contractor wants to do it in his own utility (he does not want the user to be bothered with the update process). Of course - the user will be notified and agree to this feature. Can this be done ? TIA -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Re: [android-developers] Re: How to increase FPS (now ~20, desired ~40-50)
Was just watching the video from back in May by Chris Pruett. He had a
performance slide comparing canvas to opengl and as he noted there, canvas
is much slower. I am sure you know this, but getting 30fps on a Canvas with
more than a dozen or so sprites might be difficult when you factor in game
logic, collision detections, etc. I didn't realize you were running this on
the emulator as well. For sure you'll see much faster fps on a real device.

[android-developers] Re: question about Market
I believe the Tattoo is small-class device, did you specify small- class support in your manifest? Support for additional screen resolutions and densities in Android http://android-developers.blogspot.com/2009/10/support-for-additional-screen.html Devices with small-class screens, however, will only be shown apps which explicitly declare (via the AndroidManifest) that they will run properly on small screens. In our studies, we found that "squeezing" an app designed for a larger screen onto a smaller screen often produces a bad result. To prevent users with small screens from getting a bad impression of your app (and reviewing it negatively!), Android Market makes sure that they can't see it until you upload a new version that declares itself compatible.

The emulator is not, in any way, going to run the same speed as a real
device.
Run it on a real device and see what FPS you get. Or if you want, publish
an APK and someone here will run it I'm sure (I'll do it =P)

[android-developers] Re: How to increase FPS (now ~20, desired ~40-50)
Hi,
Yesterday, I've changed my code, to work with the matrix more
effectively...
My GameEntity class now looks like this:
--GAME ENTITY--
public class GameEntity {
public Bitmap mBitmap;
private Rect mBounds;
private Matrix mMatrix;
public int mWidth;
public int mHeight;
public boolean mAlive;
public float mX, mY;
public float mVelocityX, mVelocityY;
public float mMoveAngle, mFaceAngle;
public float mRotationVelocity;
public GameEntity(Bitmap bitmap) {
mBitmap = bitmap;
mBounds = new Rect();
mMatrix = new Matrix();
mWidth = bitmap.getWidth();
mHeight = bitmap.getHeight();
mAlive = false;
mX = 0.0f;
mY = 0.0f;
mVelocityX = 0.0f;
mVelocityY = 0.0f;
mMoveAngle = 0.0f;
mFaceAngle = 0.0f;
mRotationVelocity = 0.0f;
}
public void draw(Canvas canvas, float angle) {
Matrix m = mMatrix;
m.reset();
m.postTranslate(mX - mWidth / 2, mY - mHeight / 2);
m.postRotate(angle, mX, mY);
canvas.drawBitmap(mBitmap, m, null);
}
public Rect getBounds() {
mBounds.left = (int)(mX - mWidth / 2);
mBounds.top = (int)(mY - mHeight / 2);
mBounds.right = (int)(mX + mWidth / 2);
mBounds.bottom = (int)(mY + mHeight / 2);
return mBounds;
}
}
And "draw" methods in GameView class:
--GAME VIEW--
private void drawSpaceship(Canvas canvas) {
mSpaceship.draw(canvas, mSpaceship.mFaceAngle);
}
private void drawAsteroids(Canvas canvas) {
GameEntity[] asteroids = mAsteroids;
GameEntity asteroid;
for(int i = 0; i < MAX_ASTEROIDS; i++) {
asteroid = asteroids[i];
if(asteroid.mAlive) {
asteroid.draw(canvas, asteroid.mMoveAngle);
}
}
}
private void drawBullets(Canvas canvas) {
GameEntity[] bullets = mBullets;
GameEntity bullet;
for(int i = 0; i < MAX_BULLETS; i++) {
bullet = bullets[i];
if(bullet.mAlive) {
bullet.draw(canvas, bullet.mMoveAngle + 90);
}
}
}
This gives me an extra 4-5 FPS, and now I have ~25 FPS.
It worth to mention, that I run my app on emulator, and currently have
not tested it on real device.
I decide to go little further with testing and commented out
m.postTranslate() method call, and got +4 FPS, after that I commented
out m.postRotate(), and got +12-15 FPS, it seems that rotation (with
pivot points) is very costly...

Re: [android-developers] Re: Webview - fill out an HTTP Form and submit programatically?
An alternative approach might be to use HttpClient and submit directly to the URL the form does, passing in the form attributes with your call and correct values.

[android-developers] Re: Webview - fill out an HTTP Form and submit programatically?
When using a webview, you have to realize that it's really a sort of dedicated browser object that you have a lot of control over. If you want to do a form submission programmatically, just think how you would do it in JavaScript, it's the exact same. Reporting the results or even initiating such an event can be handled directly in JavaScript, through a Java-JavaScript interface or through user input, your choice. I suggest reading Mark Murphy's excellent books on Android, there's a chapter (or two?) on webview programming that's very useful. http://wares.commonsware.com/ -John Coryat "Radar Now!"

[android-developers] Re: Service within a Thread? Thread within a Service?
Ouch! You can't do blocking operations in the event loop thread of either an Activity or a Service without the component becoming non- responsive. You can't send messages to an Activity by broadcasting a message because an Activity is not a BroadcastReceiver. You can run one foreground Activity at a time and many Services at the same time (theoretically) in a single process. They all have active event loops.

[android-developers] Table Layout Fixed Header row
Okay, so I've got this TableLayout, and its full of data - with all of the rows added programmatically. I've got the TableLayout inside of a HorizontalScrollView, which in turn is inside a ScrollView - this gives me scrolling both horizontally and vertically. What I'm trying to do now is add a header row to it that will not scroll. I've tried moving things around so that both of my scroll views were actually inside of the TableLayout and adding the TableRows to the HorizontalScrollView; my hope was to be able to then add the header row outside of the scroll views. The only other thing I can think of is having a second table layout just for the header row, but getting the columns to line up seems like it would be difficult, and also moving both the table rows horizontally simultaneously is not feasible. Any ideas? Thanks in advance -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Problems for Canadian developers
Hey Candroid developers: Now I hope I'm wrong but it appears as an Android developer in Canada I cannot sell my apps through the |Market, nor can a Canadian customer purchase my paid apps. Are these dire concerns valid? Maybe somebody from the Google mothership could clarify this important matter as soon as possible. The Android Market accepted my developer fee of $25 no problem. And I don't recall any restrictions mentioned for Canadian developers or for paid apps in Canada. I worry that hundreds of hours of my work may have been wasted. Like most Canadian Android developers who share these concerns, I am considering putting my Android development on hold immediately and perhaps permanently, and porting my apps to iPhone and/or Pre.

[android-developers] Workaround for Gallery recycling bug?
I've read in a few posts that there was an bug in the how the Gallery widget recycles views, that it was targeted for Eclair, but it looks like it's still an issue. I'm trying to use an extended Gallery (all I do is override getChildStaticTransformation). The Gallery items are all simple custom views that simply draw a FastBitmapDrawable, the images are pre-scaled, very lean and very basic. All items are 280x320 jpg's, so not huge individually. As I scroll through the gallery, I get to the same point each time and when I call BitmapFactory.decodeFlie(path) I get the "bitmap size exceeds VM budget" error. I've offset the start point in the list and it's not a specific image causing the issue, it's when I've decoded a certain number of images from disk. The other posts indicate that it's cumulative; multiple bitmaps are being held in memory instead of being recycled, and I assumed this was because the Gallery views aren't being recycled properly and hanging on to their bitmaps. I've tried paging the image set to 10-20 images at a time, this works but after a few pages I get the same exception. Is there any workaround for this? Even if it's addressed in an update, it's not really viable to wait since all phones aren't going to just instantly upgrade once an upgrade is released (judging by how slowly 2.0/2.1 is rolling out). Without a fix or workaround, the Gallery seems pretty much useless for images (unless there's only a few).

[android-developers] Re: Saving the contents of an array
If your array is not too large, I agree with theSmith, using SharedPreferences is very easy if you are not sure about how to use other data storage approaches. If you store it as a String you could then parse it and rebuild the array. If you have a lot of data, you might want to go ahead and check out using a database. Here is a quick database example I wrote recently, in case it helps: http://www.screaming-penguin.com/node/7742. Also, here are some examples of writing and reading to files: http://unlocking-android.googlecode.com/svn/chapter5/trunk/FileStorage/src/com/msi/manning/chapter5/filestorage/. See "CreateFile" for writing to a file, and "ReadFile" for reading the data back. These are a bit simplified, and the process is pretty raw, but the concepts are there.

[android-developers] G1 microphone being Overdriven when trying to use AudioRecord
Hey guys, By following an entry on Hashirs Blog on AudioRecorder Class (http:// hashspeaks.wordpress.com/2009/06/18/audiorecord-part-4/), I have made a project which should be recording PCM audio for 20 seconds and storing it in a file on the SD Card. It seems to be doing its job, executing everything properly, but when I listen to the audio recorded by my android G1 phone on a raw audio player, I find that the Microphone has been really over sensitive and I mainly listen to noise when I am speaking but only from a distance does it record some audio. Could someone please test this on their G1, by loading up this simple program on their Device, recording 20 seconds audio and when the HelloWorld text appears on the screen..the file can be taken out of the SD card and played in any simple player which can play raw PCM data. Just want to know if this problem is something to do with my project/ phone or I am missing a step... Or if someone has a working code to do this, would like to have a look and learn/ Would appreciate any help with this Cheers Tanmay -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Dialog sizing question

Re: [android-developers] Re: ATTENTION ANDROID TEAM: Take back control of Android.
I suppose it's too late, or perhaps too many wouldn't have joined up with google if they had done this, but it would have been nice if there was a guarantee from all devices that any app that runs on the emulator will run on devices. I've read not just in these emails, but on other forums as well the frustration of developers that get complaints and refunds or negative feedback because an app doesn't work on one device, but yet it works on others. It's impossible for developers to test their app on every device. I sure don't have thousands laying around to buy each device as it comes out to ensure that it works correctly. The emulator only goes so far and apparently not nearly far enough since many apps fail on some devices yet work fine on others. Is it because of device drivers for these devices that things are failing, or is it their custom build of Android for their device that is causing things to fail. How do we find out and/or avoid these issues? Like some said here, some sort of testing facility would be great.. but then I am required to pay air fair to fly to where ever they have one.. or pay a premium for testers to test it on those devices. Since the market allows for so little text, you can't really say much like "app works on devices 1,2,3,4..but not 5,6,7 yet". It's really too bad a detailed message can't be left and updated.. even better a forum like this where you can respond back and forth like we do here... limit it to 512 characters per response or something. It's all server stored, and users can scroll thru the responses, expand/hide, or choose to ignore them. It would go a long way in making it better for developers and the end users alike. But like I said before, Market is an android app as far as I know.. I've not really seen much in the way of updates in the past few months to it. Is it that hard for one developer at google or on the android team to continue to update the market app? Hell, open source that sucker and let us contribute to it.

I'm not alone when it comes to the updating issue, check this article out "Android’s Next Challange? iTunes | Linux Magazine - http://goo.gl/gPzw"; However as Dianne explained yesterday there's not much Google can do about this, since only manufacturers can release the updates for the phones, after that, getting it from manufacturers to users is relatively simple, so until the day comes that users can update the phones on their own, like we do with PCs or iPhones there's not much Google can do. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Re: [android-developers] Re: Best Server for Android MultiPlayer Games?
We're probably confusing the original poster at this point. I agree that if you're going to be writing your server you should avoid learning a new language unless it's absolutely necessary. I tend to dislike Ruby, and Python in favor of Perl. But this is because I have everything I need in Perl via CPAN. However, none of these languages are known for their speed, or for their ability to scale. You can of course add things like events, or message queuing, but this only mimics things found in Erlang. I definitely recommend Erlang to write your server. However, it's not something for the faint of heart. But if you're going be learning a new language and are worried about scalability and (soft) real-time speed you should check out Erlang fer sure. Once you get a hang of it. Implementing things that would be difficult in other languages becomes a breeze. Not to mention you can do hot code updates on a running system! I'm an Erlang advocate, so I thought it deserved a mention. Not to mention it's been working wonderfully for me so far for my android game. However, if you already know Java and you don't need any of the above I strongly recommend you stick to a platform written in that language. About hosting, this really shouldn't be a concern. Shop around datacenters, I'm sure you can get a dedicated hosting server relatively cheap. I tend to stay away from cloud hosting (like EC2 or Rackspace) because it's a lot slower than having a dedicated machine in a datacenter. Google Apps Engine, is ok. If you want your stuff hosted by google, and if you want to your server permanently married to them. (Which I wouldn't) Not to mention that it'll still be somewhat slower than having a dedicated server. Miguel.

[android-developers] how to implement search within the app?
How do we implement search within an application. I need my application to handle the search menu button click and handle the text to search data from my application's database. I have looked at the SearchManager but could not figure out how to handle the search to query my database. i could not find any related examples either on the net.

Re: [android-developers] Re: Service within a Thread? Thread within a Service?
Interesting. I've got to read up on services more. I thought when you start a service it's a new application that is running along with other background apps. Essentially, I thought you'd have the foreground app PLUS a background app running. When the foreground app closes, the background keeps on running. I also read somewhere where you have the background service start when the phone boots by listening for some intent or broadcast message. Again I have to refer to Mark Murphy's books.. he explains this really well, I just read most of it but haven't practiced it yet so it is escaping me. If you can start a background service and it polls, then you probably need that background service to broadcast a message so that when the foreground app is actually in the foreground and running, it can respond to the message to get the data. I am not sure (again) how that is accomplished, but that should be the basic idea.

Re: [android-developers] Re: Best Server for Android MultiPlayer Games?
Hey Robert, Love your online stuff.. read it all. Still got it bookmarked in hopes of using some of it for some game ideas. That said, I think the Ruby language is quite a bit more difficult at least in syntax than Java is. If you already know the Java language, why learn another language for the server component? Unless you have lots of time or it's a requirement, I would stick with Java over Ruby. I am probably one of the few that look at Rails as more difficult than Java. For me, having taken a stab at Ruby for a short bit, the language syntax reminds me of Perl.. which is God awful. It's more difficult to read and even with the Rails framework, you still have to learn the basic concepts of MVC design, ORM, and such. If you haven't seen JEE 6 with EJB 3.1 and the Jersey REST stuff, you really owe it to yourself to check it out. It's quite amazing how fast it is to develop with. I installed GlassFish v3 and had a simplified RESTful API with back end ejb -> mysql ORM mapping in an hours time. I do know a lot about the REST server side, but the EJB stuff was fairly new to me and the most difficult part was figuring out how to connect GlassFish to mySql and accessing that via the EJB context. There has been a vast number of improvements especially in the area of developer productivity with JEE6 that I think compares favorably with anything RoR offers, and you get a lot more to boot.. not having to learn a new language, more frameworks and so forth. If you've got time, and want to pick up another language, go for it. For me, I can do more in Java than I can with Rails, and for me it's quite a bit faster too. I am one of the few that argues against going to RoR, Python or PhP for server solutions, although I am going to pick up on python as it's a very interesting language and is used quite a bit in scripting and other solutions. I used to be in the camp for learning everything new under the sun.. but now that Java is more than fast enough to handle heavy loads on the server side, handle any sort of Desktop application you can imagine (ooh..with the exception of high-end games and high-end low latency music apps), and you can use the same language for Android mobile too, I personally say stick with the one language you know already, learn some more of it (server side in the OPs case) and keep it all one language. Like I said, JEE6 comes bundled with Jersey, making it only a couple lines of code with no xml configuration to get a RESTful service in place, and a few entity pojos with annotations to have the ORM done as well. It's impressively easy to work with now. No matter what solution he goes with, he's still stuck figuring out how to host it.

[android-developers] Re: Best Server for Android MultiPlayer Games?
I'll mention it once more because it seems to be overlooked but for any kind of turn-based game, I have to recommend: Server side: Ruby on Rails as the platform Phusion Passenger on Apache as the deployment manager REST as the method JSON as the high level protocol This is free, VERY easy to work with and will be able to work with most design requirements. Android ships with JSON parsers and RoR has built in ORM->JSON support, so it'll effectively dump the results of queries directly into JSON without you having to add any code. I recommend using Aptana Studio with RADRails as the dev environment. You can start up a local Mongrel server and test directly against it with your device via WiFi, then just copy the rails app to your server to move it into production. I use these technologies extensively. Try the full version of Wixel if you want to see how it works for online play. It has been 99.999% reliable and has handled peaks in traffic just fine.

[android-developers] Re: Service within a Thread? Thread within a Service?
Thanks for the replies. Kevin, what I'm trying to accomplish is [seemingly] very common in the mobile world: 1) User starts app 2) App retrieves info from remote server based on the User's interaction with the app 3) When app is not in focus (or closed) a background service continues to retrieve updates from remote server For point number 2), I understand that I could simply use a background thread (eg. AsyncTask), since the data is to be returned to the current activity. But for point number 3), a simple background thread is not appropriate. My question is this: Since I will need to write a service to perform [much of] the same functionality in point 3) as my background service will be performing in point 2), wouldn't it just make more sense to skip the background thread and perform all of my polling through the service - and simply call that service from within whatever activity may need it at the time? But that raises another question: calling a service from an activity seems to lock the UI - so when polling remote servers, shouldn't the service either be run in a new thread, or rather, shouldn't the service spawn its own thread?

[android-developers] Re: Best Server for Android MultiPlayer Games?
A couple of months ago I started looking into options for converting some of my single-player turn-based games into online multiplayer versions...it's the number one request I get from end users. I investigated SmartFoxServer since they do have support for Android. I set up a test server and worked through some of the tutorials. It actually worked quite well, but of course there is the cost of the server software in addition to the cost and logistics of hosting (as Kevin just mentioned). A friend of mine mentioned the possibility of using Google App Engine as a possible server solution. It makes a lot of sense (at least on paper), since GAE: 1) Is free (up to a limit, a very high limit) 2) Scales very nicely 3) Uses a Google account for authentication, so ideally authentication from an Android phone should be seamless, right? Well, I've spent a fair amount of time getting the authentication working (search this forum if you're going this route). Our first GAE/ Android online multiplayer game is coming together, but we're still working through some issues.

[android-developers] Re: Accelerometer on Motorola Droid
Hi PhoenixofMT, I've looked into augmenting the accelerometer data with GPS info. The major hurdle is not the physics, it's the resolution of the GPS data provided, which is only timestamped to the nearest second! This makes it extremely difficult the calculate any sort of realistic figures without a lot of assumptions. The accelerometer though, after proper calibration, does provide figures that allow for pretty accurate calculation of acceleration/ speed/distance/power/torque...

[android-developers] Re: Accelerometer on Motorola Droid
Hi, As PhoenixofMT said, calibration from factory is poor, but sufficient for most games and the like. I had to write a similar calibration routine into my software before I managed to get any realistic figures from the accelerometer. The user is required to sit the device in the various orientations, then you need to scale the device provided accelerometer readings proportionally with your calibrated ranges. I also found that changes in temperature affects calibration, so I recommend the user to calibrate the device every time they use the application :( .

Re: [android-developers] Re: ATTENTION ANDROID TEAM: Take back control of Android.
Couple thoughts on this. TreKing has a good idea. I've seen this done before. The only thing I would be worried about is as a user of the app, having to pass thru all this content to get to the app. Sure, you probably allow them to skip it. A different idea.. is this even worthy..is to provide a link to your site and let all the info in there. That way your app is smaller, the user can go to your site when they want or if they want, and you can provide more info and details, feedback form, etc. Of course, I would guess a lot less people will actually go to the site tho. It would be great if there was some sort of Android Developers Info site that google provided where we could get some questions answered, and info about when things will be available posted. For example, a rough idea when OpenGL/CL will be distributed, a JIT in the JVM, and more markets that developers can sell to. As well, if the Market is just an Android app, why can't that be updated fairly quickly? I know some things take time, like getting into other markets..although a year with not many added does seem very long. But the market app is basically a pointer to server side data.. filtering it and such. Why not make it more robust, allow longer comments, a forum like comment system, more screen shots, and so forth? That would greatly benefit developers and users alike.

Re: [android-developers] Best Server for Android MultiPlayer Games?
Wow..where to start. First..I never heard of or looked up those servers you mentioned. But more importantly, exactly what do you need from the server side component for your game? Is it to keep track of player locations in the game world, store all their info, profile, achievements, scores, etc? Give a little more detail on what you plan to do. As for doing your own server.. not knowing how as the above post said..it's not terribly hard if you know one of the server side favorites, like Rails, php, or Java. The main problem you face is.. where do you host it? If you run the server at your home.. you run into a number of issues. Does your ISP allow you to run servers (do they have a policy that says you cant.. do they run bots to scan all ports to see if you are serving.. etc). If they do allow you to, now you face the problem of using a static IP, a dynamic IP routed thru a service like dynDns or no-ip, or actually buying a domain name and assigning it your static ip (or the dyndns/no-ip info) to route to your server. Now once you get it to your server, you've got to worry about scale.. should you need it. If at all possible you want to remain stateless on the server side so that you can avoid having to worry about a user that has say a session (via cookie perhaps) on a server that goes down.. and loses any/all data they have that was not stored. If you got hundreds of users on a server like that..you're going to have a lot of pissed of players. So assuming you remain stateless, then you mostly have to worry about a load balancer (and that needs to be fault tolerant as well) to round robin between two or more servers as you scale up. But, that is all stuff you need to think about once you figure out if you're going to do your own server side. Remaining stateless a basic server with 4 core cpu and 16GB ram should be able to handle thousands of simultaneous player accesses.. depending on the data coming in on each request. As for the right "protocol" to use.. I personally prefer REST. It is the easiest thing out there to implement on the server side, and at least for Java, Jersey (bundled with Java Enterprise 6) is very easy to use. It even supports automatic conversion of json or xml into JAXB objects, so that you as the developer on the server side do not need to deal with xml or json at all. AS well, there is a java client library that comes with Jersey that can be used by clients to send xml or json by turning JAXB objects into xml or json, depending on the Content-Type heading. I am not sure about Rails, I've read that it's quite easy to do this as well. Being that I've worked within the Java server side for years and have been directly working with REST the past almost two years, it's a real pleasure to be able to work with and it provides a very solid and yet easy to use API for clients. Even better, you're not tied to one platform. You can easily make REST calls from Android, iPhone, Palm, Blackberry, and any other client side technology. If your game is doing well and you are interested in pursuing this, shoot me an email directly.

One thing I wish AdMob would do for Android ads is offer House Ads, which they do for iPhone and mobile web ads. A House Ad is basically an unpaid ad that you can provide that will show up in the app during the xx% of the time when AdMob doesn't provide an ad. Some use it to advertise other apps they've written, but I generally use it for an ad saying "upgrade to the paid version and remove ads" in my free, ad-supported version.

[android-developers] Playing RAW audio on Android from a network stream
Hey Guys, I am working on streaming RAW audio from a network location, but finding it a bit hard. So here is a description on what I am trying to do : I want to be listening on a port on my phone for some raw audio data, that will be sent from a location on my network using netcat. I pretty much want to perform a netcat listen function on my android and pipe out the data to the audio hardware. I have looked at the AudioRecord and AudioTrack classes which give access to raw media and might be useful in this task. I was wondering if you could refine the following algorithm for me and point me to the implementation, as I know a bit of java but not too confident with using Sockets, Pipes and AudioTrack to do this. The procedure i am planning to use is: 1) Use a new ServerSocket(port) to listen on particular port. 2) The other side connects to this port using netcat : 3) Make a new Pipe which takes the outputstream from the socket, and feeds it into the input of the audio hardware. 4) Use methods from AudioTrack to play the raw audio in real time Any help in this area would be very much appreciated, as I have been struggling to find anything in this area.

[android-developers] Re: Need current location long and lat
It's more involved than simply turning on the GPS and getting a location. You'll have to decide how coarse of a location fix is good enough too. If you'll accept a location fix of 1000 to 3000 meters, then you might just skip using GPS and use the network location service instead. If you need something better than 1000 meters, then GPS will be the way to go. Another option is a hybrid approach that uses either depending on which is available and which returns a fix the fastest. While more complex to setup, the results are worth the effort. -John Coryat "Radar Now!"

Re: [android-developers] Re: Service within a Thread? Thread within a Service?
One thing you haven't indicated is if you need this remote access when the app starts, or if you actually need to periodically "wake up" and poll the remote service? If you only need to have a user start your app.. and at that point it requests to the remote service once.. or while the app is running, then using AsyncTask is the way to go. If you need your app to periodically poll the remote service, than a service may be the way to go. A service would not require a separate thread that I know of because it is not tied to a UI. It's a background task, with no UI. On Tue, Jan 19, 2010 at 1:14 PM, jotobjects wrote: > I don't think it will accomplish anything to start a service in a > thread.

Re: [android-developers] Best Server for Android MultiPlayer Games?
Hello Atif, I'm developing my own server for a multi-player game, so I think I can weight in with a degree of 'expertise.' To start off, I've never heard of any of the servers you mentioned, so I'm not going by first hand experience, but rather from the information they have on their website. So, please don't take anything I say to be 100% true. Red5 - Seems overly complex for such a simple project. Do you need streaming? It seems that's one of its main features. It has java examples and bindings so that'll make coding the client and server a bit easier since your brain doesn't have to switch between Java and something else. I don't see anything that would actually help in creating a multi-player game, beside mapping data. (That is, being able to send data from the android client and the server being able to interpret it and something useful with the data.) I really can't recommend this for any game development. Not to mention that there are no specifications as to how efficient it is, or how low its latency can be. ElectroServer 4 - Seems to be primarily an ActionScript/Flash server. According to the site: "The ElectroServer API acts as a liaison between the game developer and ElectroServer – formatting and initializing all transactions that occur between the client and the socket-server." As you can see, this can add a significant amount of overhead/latency if this formatting isn't done fast. "Flash clients written using ActionScript 3 gain even higher performance and reduce message size further by using the binary protocol." So, for ES4, it seems using the binary protocol is the best way to go. It actually looks fairly simply and complete and just might do the job. SmartFox - Looks pretty stunning. Not to mention they had mobile devices in mind when they made it. So that probably means the protocol is efficient. They seem to APIs in a lot of languages. (Say you want to port your game to iPhone later.) This one seems to be the most recommend-able off-the-shelf server. However, to me, java and high-performance/low latency don't go together. But for your kind of game, it should be more than enough. There's also nothing like having professional support for a server/platform. Now, I'm not sure if you even need all those features, or if you have/are willing to spend the money on them. I, like a few posters, recommend that you make your own server. It really is a lot simpler than you think. You can do it in php, perl, etc. It doesn't have to be a new-age language. You simply encode your data in JSON, send it to the server. The server performs some basic database operations and returns back data encoded in JSON. That's it, doesn't get much simpler than that. However, you'll have to code a lot of the logic and be dealing with databases. (Which is not a bad skill to have.) Android has excellent support for JSON. I say this because sometimes, it's a real headache dealing with commercial products, specially if it's just a simple card game. Also, you'll be keeping most/all the profits. (Depending on the server's pricing scheme.) Scalability, yes it's an issue. But a lot of the time it's just an issue of knowing how to break down your game rooms. For example, you don't expect to have 200,000 users in the same room at the same time, do you? 200,000 players overall should be feasible using simple JSON.

[android-developers] Re: JDBC Driver for SQLiteDatabase
You can just include the Android driver in your application if you

[android-developers] How to factor code for Free/Paid app versions?
I have a project which I want to split into a paid and a free version. I do not care to double my management of the res/ folder and would even like the AndroidManifest.xml to be the same file except for the package line. Worrying little about hacking (at this stage -- my app is not copyprotected anyhow so other avenues of vulnerability are already open), it might be sufficient for me to have all the logic in the free app, and to enable/disable functions based on the app's own package info. What strategies have others used in this regard? I have soft-linked the source from a new Android Eclipse project folder tree to the existing one (the new is to become the paid version and the old one will become the free one with some logic paths being conditionally stubbed at runtime), reserving the new source file hierarchy in the new one to the sole purpose of containing an MyMainActivity.java file (as it will need to be in a different package- folder than the one for the free app's). But the res folder appears as though it might be more difficult. Ideas? tone -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: setContentView fails when creating a new activity
I've tried to reply to this thread twice today but it refuses to show
up here. Maybe the third time will work:
I find that, for me, exceptions triggered by setContentView are often
simple oversights in the layout file, such as a missing layout_width
or layout_height on one of my view declarations in the xml.

[android-developers] Unable to run emulators with SDKs 2.0, 2.0.1, or 2.1 - all hang on startup
Hi, I'm having a problem. I had the regular 1.6 SDK installed and have been developing using Eclipse 3.5 on Windows XP with no problems. Using the Android ADB manager, I installed newer SDKs: SDK Platform Android 2.0, API 5 (tools rev: 3) SDK Platform Android 2.0.1, API 6 (tools rev: 4) SDK Platform Android 2.1, API 7 (tools rev: 4) Now, I create a new Virtual Device with any of the above targets. No emulator will start, no matter if I change the skin, use an SD card or not. Nor will using "emulator -avd" from the command line have any difference with starting it via Eclipse. And of course I have also tried to restart my computer as well. Most emulators never get past the "A N D R O I D _" text, and give no logcat output. The one emulator that will actually give me logcat output (due to it going online, according to the device manager) is 2.0.1 For the 2.0.1 emulator, it does show the flashing ANDROID logo, but never makes it to the Android desktop. The last logcat output that appears with 2.0.1 is: DEBUG/dalvikvm(98): No JNI_OnLoad found in /system/lib/libwnndict.so 0x43b74718 DEBUG/dalvikvm(98): +++ not scanning '/system/lib/libwebcore.so' for 'createWnnWork' (wrong CL) DEBUG/dalvikvm(98): +++ not scanning '/system/lib/libmedia_jni.so' for 'createWnnWork' (wrong CL) ...

Re: [android-developers] Re: ATTENTION ANDROID TEAM: Take back control of Android.
Very interesting thread so far. I completely agree with the sentiment that continuing to develop and support an app on Android with all the differences in platforms and versions available is making a developer's life difficult. Especially with the complete lack of basic but essential functionality in the Android Market (no way to see comments in the console, no way respond to comments, STILL stuck with 325 character limit, 2 screenshot limit ... the list goes on and on). Regarding the issue of getting low ratings on the Market because of all these variations: personally, I've given up on waiting for the Market team to address these issues and have, instead, used the only means I have to communicate with users - the app itself. With each update I show users a series of dialogs that: 1 - Provide a detailed account of what's new in each release with clear instructions on how to use the new features or what bugs were fixed (something that, as a user, annoys me that more developers don't do). This also saves me from wasting any of my precious 325 characters on what's new. 2 - Lists all negative comments on the market with a response from me for each so users know I take that feedback seriously and am aware of their issue. Yeah, you can respond to the the latest comment on the market with your own, but you can only leave one comment at any given time and that leaves others unaccounted for. Plus, many people leave comments and never bother updating or checking in again. This way it's in their face so to speak when they update and serves as a reminder to update their comments (assuming they haven't un-installed and moved on). 3 - Reminds users that there are so many variations of phones and Android versions that it's pretty much impossible for me test everything, that I have no way of responding to these market comments, and if they have any issues or questions they should email me and give me the chance to fix their issues before leaving comments. I find this to work very well. I don't have a single "Force Closed. Uninstalled" 1 star comment on my apps. In fact, quite the opposite, I get quite a few high ratings for providing good support. Remember, most users have no idea what we as developers have to deal with. All they know is whether your app works or not on their particular device and that the market is the quickest and easiest way to leave you feedback (especially if they're having issues). Ideally Google would have all these issues ironed out but that's obviously not realistic so it's up to you to educate them on the limitations you have to work with. - TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/treking -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Help with Camera.Parameters.getFlashMode()
All,
I am developing an app that uses the phone camera, and I want to set
the Flash Mode, if flash exists.
>From documentation, it looks like I need to call
Camera.Parameters.getFlashMode() and check if it returns null to
determine if flash exists.
Note: getFlashMode() is supported from API level 5
However, when I try to run this app on a phone with cupcake, I get an
error:
01-19 14:02:43.404: ERROR/dalvikvm(18891): Could not find method
android.hardware.Camera$Parameters.getFlashMode, referenced from
method ...
I tried to call this code based on SDK version as follows, but that
does not work either. Looks like there is a class verification thats
fails at init:
import android.os.Build.VERSION;
int mSdkVersion = VERSION.SDK_INT;
Camera.Parameters params = mCamera.getParameters();
if (mSdkVersion >=5 && params.getFlashMode()!=null){
params.setFlashMode(Camera.Parameters.FLASH_MODE_AUTO);//set auto
flash
}
So now I am wondering if there is any other way to check if flash
exists? or is there a way to conditionally compile code based on
mSdkVersion?
