[android-developers] Re: how to detect if a phone is running HTC sense UI
There are also subtle differences in the way some of the standard apps work, such as Contacts (aka People). The handling of Phone contacts is different in HTC Sense, for example. This difference exists whether the HTC Sense Launcher is selected or not.

My interpretation is that they are used to phones (say Nokia) where a globally selected theme is applied to just about everything but games. A number of users have very boldly stated that they withhold one star until this bug is fixed. As there (currently) is nothing like that, it is somewhat tempting to explicitly alter the UI for a few of the most common styles around. I've personally elected not to do that so far, but I can understand why some might. Best / Jonas -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: onCreate, onStop..... super.onCreate, super.onStop... called before code or after?
Yes, whether/when to call an overridden method in a subclass is one of the unfortunate consequences of using implementation inheritance. Its a shame that the Android SDK makes such heavy use of it (inheritance), Over the last 10 years I had thought enough of us in the Java world had finally gotten the message that its too fragile a way to construct a strong base for development. Most frameworks of recent years had tended to favour composition using interfaces and a set of concrete (typically final) implementations, and rightly so. Its one of my two beefs with the Android SDK. The other being the profileration of int constants instead of enums. Trying to choose the correct constant value from an vast list of similarly named constants that all have the same type. consumes too much dev time and is fraught with danger. Just look at the number of constants in the android.media package and try to work which constants of which class go with with methods. Yes I understand the performance trade off between ints and enums, but a) We know that JVM perofrmance continues to improve b) The compiler/jvm could be tuned to cut weight from any unused portion of an enum.

Usually, no, it doesn't matter. Of course you could run into issues where your derived functions depend on state that is altered by calling super. This does not seem to be the case in Android, at least as far as the life cycle methods are concerned, AFAIK. I tried both ways and it works but I'm afraid to maybe get some memory leaks or things that are not apparent now but can cause harm or unexpected issues on some users... I think you're over-thinking the issue. In general, I'd say just call super first and then do your work, unless you have a good reason to do otherwise (the documentation tells you to or you know the implementation and know why you're doing it differently). Mark, not calling super at onCreate will lead to a crash... :) To clarify, Mark said: There's nothing in Java that forces you to have super.onCreate() at the beginning. Which is true - a) *Java* does not require this - you will compile and run fine. The crash you get when omitting onCreate is an *Android* requirement. And b) it's not required to be at the beginning of the function as calling super in the constructor is. I got maybe a little more insight on this but still no definite answer... maybe is not much of a big deal? :P It's really not, unless it breaks your app. It probably won't though. --- -- TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: How to store questions for quiz type application
True enough, and if you are only reading, atomicity doesn't matter. But if you want to record answers? Files are well suited to either read-only uses. But once you start writing, you have the potential for partial updates unless you use a rename or delete to mark the end of the update. Which is done far too seldom.

With a database, you still have to think about transactions, but you can group any set of operations in a transaction, and there is a single, reliable mechanism for reliable transactions. You don't have to invent your own. I would definitely use multiple tables. For example Question: * id (primary key) * answerID (foreign key constraint on answer table, do not chain on delete) * number (if you want to define a numbering for your questions). * text Answer: * id (primary key) * questionId (foreign key constraint on question table, chain on delete -- i.e cause this to be deleted if the question is deleted). * number (if you want to control for a consistent order, rather than randomize it). * text If you're recording the responses: Response: * id (primary key) * questionID (foreign key constraint on question table, chain on delete) * answerID (foreign key constraint on answer table, chain on delete). You'll also want to define indexes -- for example, on Response.questionID, which should probably also be unique (and Answer.questionId, which should not, or Answer.questionId, number, which should).

Yes, this is definitely the issue - however now I am lost trying to decode what these fields are.

In the top level of the folder you will see a screen shot of what I see when running it on a 480x800 emulator with 2.2.

Robert Green, thanks again for your informative answer. I added the MODELVIEW mode right after setting the viewport, and did a loadIdentity after that. No change, but I agree its the correct thing to do. Still zero lines visible on the emulator (even when I scale up its display). Looks fine on the G1. Off to read the manuals again ;-( Per your question: gl.glScalef(1, _hgt2width, 1); float lscale = .002f*MyApp._curScale; It could be that I just don't understand what this is supposed to do but magic multipliers like .002 never look good to me when you're having issues with drawing precision. I am drawing in a geographical coordinate space, not pixel space. So the scaling is used to transform from that space to the viewing space. In my geographical space, my coordinates are in (projected) lat/long specified with higher precision than even float can deal with (which, fortunately, isn't a problem with this app). My test case uses simple coordinates, but I left in the same scaling as in the real app. // ditch the fixed point (it's only faster on first-gen devices and only in certain cases) For now, I'll keep it because a bunch of code is in it, and I am testing on a first gen device. // now if you want a line 1px wide on the 10th line, draw a line with x on 9.5f I just want my lines to show up, and my reading of the openGl documents indicates that they should, if drawn with a line width of 1, no matter where I put them.

[android-developers] Android Appwidget resolveUri failed on bad bitmap uri
Hello everybody,
I'm programming an appwidget that downloads an image from a website
and displays it. The approach is easy, but I get an error, if I want
to set the imageView to the URI of the downloaded image.
First I set the imageView with updateViews.setImageViewBitmap, where
updateViews is a RemoteViews Object. The Problem was an Transaction
Binding Error, because the images gets serialized and the transaction
became to big. So good so far. Then I decided I want to save the
picture on the ! internal ! (not external / not sd-card) memory. The
download works fine and in my preferences activity of the appwidget
the downloaded image gets displayed. But, when I go back from the
preferences activity then the Widget doesn't show the image.
The error occurs is: INFO/System.out(151): resolveUri failed on bad
bitmap uri: /data/data/com.mywidget/files/temp.jpg
But the preference activity can display the image with exactly this
URI!
So where is the problem, I really can't find it!
This is the part where I create my UpdateViews. This gets called by
the UpdateService!
String filename = temp.jpg;
context.deleteFile(filename);
FileOutputStream fos;
File file = context.getFileStreamPath(filename);
Log.d(TAG, BuildUpdate: +file.toString());
try {
Bitmap bmImg =
BitmapFactory.decodeByteArray(data, 0,
data.length); //options am Ende einfügen
fos = context.openFileOutput(filename,
Context.MODE_PRIVATE);
BufferedOutputStream bos = new
BufferedOutputStream(fos);
bmImg.compress(Bitmap.CompressFormat.JPEG, 100, bos);
bos.flush();
bos.close();
fos.close();
} catch (FileNotFoundException e) {
Log.d(TAG, e.toString());
e.printStackTrace();
} catch (IOException e) {
Log.d(TAG, e.toString());
e.printStackTrace();
}
updateViews.setImageViewUri(R.id.ImageView01,
Uri.parse(file.toString()));
I hope someone can help me with this error.
Thanks a lot,
Christian

[android-developers] Which Background model to run
Hello, I am trying to develop an application which will require a service to run in the background. I am relatively new to android programming, and after reading many posts, blogs, how-to's and books on creating and managing services, I am still pretty confused about which model I should try to use. First, let me present (in general) the application requirements: I need an application which will spawn a background process (service?) which will connect to a bluetooth device. The bluetooth device is designed to deliver data to the android device. The issue is that the data could come in at any moment, so the bluetooth connection has to stay active. Note that the application is a VERY SPECIFIC app and is NOT intended for public use. I do understand the arguments for not having background apps running all the time, but please understand that this is a very specific application for a very specific client. Now, in general, I think the program flow would be to start the application (and launch a UI activity). Then I need to configure and connect to the bluetooth device. At this point, the user should be able to do other things - make phone calls, check their email, etc., while the bluetooth connection is still active and potentially receiving data. If data comes in, a notification is fired, etc. So here are my questions and concerns: 1. If I start an app (which spawns a UI activity and ultimately my bluetooth connection service) but the app is killed, apparently, the service handling the bluetooth connection is killed as well. How can I keep that alive? I read that Service.setForeground() was depricated, but even if I were to set it to the foreground, if the app is killed, the service is killed as well. I need to have it run in the background with as high of a priority as possible (again, I do understand that this is considered bad form, but this is a specific app and this functionality has been requested by the client). 2. If I started the app (and the service, etc.), but the user, say, answers a phone call, the app is put into the background. However, let's say the user goes back to the home screen and starts a DIFFERENT instance of the app, i.e., he doesn't hold down the home key to select the already running app from the task manager but starts a completely new one. If the service handling the bluetooth connection is still running, how will this new instance behave? i.e., how can I get it to connect to the bluetooth service which is ALREADY running in the FIRST instance of the app instead of this new instance? Do I have to use some form of a Remote service instead of a local service? This is where I'm a little confused by things as it seems remote services and defining an AIDL seems to create a lot of extra overhead, and since I'm already creating a lot of overhead with the service running in the background all the time, I want to keep that as small as possible. How can I insure I am connecting to the same service already running? Thank you for your time and any advice you can give me.

[android-developers] Re: Why is Android so buggy?
From the point of view of a (relative to you) dumb user of a nexus one, I'd be glad to add a bit to the disscusion. I'm running android 2.2 froyo on a nexus one, and i'm loving it. No other phone comes completely unlocked, allows tethering and a huge app catalog while not being on any carriers leash. I love pretty much about android but there ARE many glitches that have nothing to do with the sdk or developer tools that (except maybe when i flash my phone) I've never used. I found this discussion through search: After i went out of alarm clock mode and the phone got stuck in a weird kind of state. Any time I tried to interact with the home screen i'd get haptic feedback and zero response at the homescreen. After a couple of seconds trying to kick it out of that state the phone kind of bricked and I had to hard reset it (take out the battery) to get it working again. Stuff like that happens to me from time to time. Besides this incident, just a couple of interface refinements would do android quite good, like auto-fitting text in browser when using multi touch and not the zoom buttons etc. All that said, it's the best platform out there today (together with iOs, no offence), and my only real choice. Definitely the only truly customizable portable platform that exists today for mobile at all, and that's HUGE for 2 years of work. It's pretty buggy at times, but that'll go with time I guess (: Running FRF91 on an att band nexus one. Cellcom, Israel. Thanks so much for this amazing product, I'm excited to see where android and the phones running it evolves, and I'm anxious to see android market share roar, because honestly I think that besides the Iphone android is the only real decent mobile os out there. Iphone being the simplistic platform with a great fluid physics-interface UI, and android being everything that the iphone blatently isn't.

[android-developers] Re: Android preprocessor, //#ifdef...
So much to say about Java except that's just talking religion. So back to the original topic. Sometimes just because you are adding in debug code doesn't mean you want a performance degradation. Java has mechanisms for some of this but just for example, tracing. Doesn't matter what you are tracing/tracking, if you are storing some sort of ownership for easy of debugging, you might just want this is production. Especially, 1.0 products that tend to have many more deficiencies. Whether that fits RichardC's reasons is another story. While not specific to Java, I've had enough failures between xml generation, aidl, etc., that there always seems to be preprocessing of some sort whether it got included in a language or not.

That, to me, is worth arguing about! If the OP wants to use preprocessor, nothing's stopping them. Indeed, as Bob Kearns points out, Android SDK generates R.java from several XML files, which is pretty darn close to what a preprocessor does. Would it be that hard for the determined developer to add a preprocessor hook into the SDK build script - even on Eclipse? Come on folks, this is open source code! Even Atlassian lets you modify the Jira and Confluence source code! My $0.02 is that even if javac did have a preprocessor, few real Java programmers would deign to use it.

When I run this code, it can start to listen on port but can't accept any
incoming connections. When it runs into serversocket.accept function, it
never return, just like dead lock.
I found that if I establish any connections from my phone to computer,
then
my phone could be successfully found that there're incoming connections
and
of course, accept them.
In emulator, above code works fine, has no this strange problem.
Is that my phone's bug or I have something wrong in my code?

[android-developers] Re: Looking for a design tip/advice/doc
If you are just doing a few items, it's not going to be a big deal. Same with grabbing data from a database. It's an issue when you have to scroll through lots of data and repopulate views, deal with flings, etc., while maintaining good speed. Sounds like you won't have to deal with this. Another way to approach this is to work with something like SimpleCursorAdapter and map your database onto the layout so it automagically populates. This only makes sense if you are going to display a set of info; lists/grid. Cheers On Aug 2, 10:11 am, Sebastián Treu sebastian.t...@gmail.com wrote: Hi all, I'm kind of new to android development. I have read from many sources that findViewById() is a costly operation. I'm making an application that deals with 5 TextViews to provide different kinds of information (distance, duration, title, description, etc) from a database. I'm using listeners to catch touch/click events and feedbacks a handler. The main function of the handler is to received a position in the Cursor where the new information needs to be displayed. I mentioned earlier that findViewById() is a costly operation. So, I don't call this method in the handler. Doing so, it will retrieve every time the Views when user touchs/clicks some widget. Is it right to populate the Activity with private members of the Views/Layout it displays? I mean, I don't like it. I don't know why, but seems that I'm populating too much the activity. I'm aware of the android:onClick xml attribute, but in my case I also use long click listeners. So, a piece of onCreate() looks like: imageTitle = (TextView)findViewById(R.id.title_image_view); title = (TextView)findViewById(R.id.title; desc = (TextView)findViewById(R.id.desc); duration = (TextView)findViewById(R.id.duration); distance = (TextView)findViewById(R.id.distance); And all of those are private members, wihout mention the cursor.getColumnIndex() for each. I thought on implementing Handler.Callback and set on the Hanlder.Callback constructor implementer a View array or a View list or something, but I also need this objects later to set other listeners and setups. Is this right? I cannot think another way, as I need the reference to the object, and also the Cursor reference that the handler will move to the position provided and update the correspondent View. I will really appreciate either an advice or a useful link/info/doc to read in what concern in this kind of designs. What I do not like is that It looks like imperative programming filling the Activity with global variables. Thanks, -- If you want freedom, compile the source.

this is good news, do you know when next ver of ADT will be available through Eclipse update? On Jul 9, 2:36 pm, Xavier Ducrohet x...@android.com wrote: Just to give an update to anyone still reading this thread. The next version of ADT will include fixes for: - Issue with the library needing to have a single source folder called src. Any number of source folder, of any name, even under other folder (src/java). - Issue with project name containing characters that aren't valid for folder names. - Libraries depending on libraries. We've also made the link of the library source folders in the main project much more robust. By the way, we highly recommend to people using library projects in Eclipse to set their workspace to automatically refresh. This is due to Eclipse not realizing that the code inside the linked folder (in the main app) is the same as the code in the library. Since Eclipse considers them to be different, editing the code in one location requires a refresh in the other location. Setting the workspace to refresh automatically helps a lot.

I'll get that source code tomorrow from the first link you gave and see if that works on the device if so I'll try to dissect it to see where the difference is. In order to use the maps do you have to place the uses-library tag inside the application tag in the manifest or are there other ways of using it?

[android-developers] Re: My Eclipse 3.5 always lag and have to force close - why?
It's long been my opinion that the minimum development environment should be 8 GB, quad core. And, ideally, solid-state disks. Definitely *NOT* a 5200 RPM or slower hard drive! Ever! I run on a 4GB, dual core laptop, SATA 7200 RPM hard drive. But I've also run on 8 GB, quad core, and know what a difference it makes. I figure there's no point in replacing my computer until I can hit that benchmark. This was the benchmark about 4 years ago. But it makes a HUGE difference what else you are running. Here are some of the worst offenders: * GMail -- any browser. * Firefox -- any content * Eclipse -- don't open more stuff than you need. And you can experiment with giving it more memory, so it doesn't have to GC quite as often. But that makes the GCs it does do touch somewhat more pages. Also, make sure your hard drive is defragmented, and that you clean up your temp directories from time to time. A huge temp directory can make a lot of things really beat on the disk as they do trivial things with tiny temp files. It's surprisingly easy to get a huge temp directory over time. And finally: Pay attention to antivirus and online backup software configuration. You do NOT want your antivirus software looking at every file you touch in your build tree. You do NOT want your backup software instantly backing up every intermediate file created during the build process. Still, insufficient memory is the biggest cause of poor development environment performance in my experience. Eclipse does a huge amount of stuff for you, but it requires RAM to hold all that parse data, etc. Closing editor buffers, projects you don't actively need (like the demo project!), etc. can significantly reduce Eclipse's memory usage.

The only trick part is doing the imports. Stub classes are a one way.
Interfaces (don't worry about the performance overhead. Count on the

Why force everyone to do it the so called right way? Why does C# have

[android-developers] Re: Android preprocessor, //#ifdef...
Well, perhaps this illustrates your second point, but: http://tinyurl.com/sun-concurrent-gc Or it may be that they're not concurrent enough for you. Concurrency isn't an absolute, and there are various ways of describing the upper bounds on how much delay a concurrent algorithm can impose on other threads. (Your point about stringent response time requirements suggests this may be your issue with calling it concurrent). GC benchmarking is hard work and tricky, and I haven't done it in a long time. I appreciate the anecdotal data; do you have benchmarks behind it? You've aroused my curiosity about the current state. I have generally been more concerned with compatibility in huge code bases rather than performance differences (which can generally be overcome with hardware -- not concurrency, though), so I've mostly avoided non-Sun JVMs when possible. But I like that there are alternatives of increasing quality. Especially given recent corporate history... Thanks.

Re: [android-developers] Does all Android Devices support Map API
As far as I know, yes, but this is not a guarantee. This is not something you need to worry about, because to use the maps API you need to have uses-library in your manifest, and Market will then hide your app from devices that don't have the library. You can also do this yourself on newer platforms by making the library optional and when running use the normal Java facilities to check if the maps APIs are available in your ClassLoader.

Re: [android-developers] Re: LVL returns LICENSED with anonymous accounts...
Yes, it's necessary. We need the application to be listed in Android Market so that we can actually check and see if you've purchased it. (We send the package name and version code of the application to the licensing server -- if your app isn't published, we won't find a match for the package name.)

[android-developers] Re: Update delete a directory and how to prevent this from happening?
I did use getExteranlStorageDirectory() method but i realize Android always mount it to /sdcard I am starting to think why not hardcode.

I think it is sucefully creating the server socket, the problem seems
with the client and where client is not polling to the server port.

I'm now facing a very strange server socket problem, I have a server

public class RequestListenerThread extends Thread {

t.start();} catch (InterruptedIOException ex) {
break;
} catch (IOException e) {
Log.v(FE, Network I/O error:

break;}
}
}
}
My target device is running on Android 1.6 2.1
When I run this code, it can start to listen on port but can't accept
any
incoming connections. When it runs into serversocket.accept function,
it
never return, just like dead lock.
I found that if I establish any connections from my phone to
computer,
then
my phone could be successfully found that there're incoming
connections
and
of course, accept them.
In emulator, above code works fine, has no this strange problem.
Is that my phone's bug or I have something wrong in my code?
Thanks a lot!

Re: [android-developers] Why is Android so buggy?
Android is buggy, yes, I totally agree with you. The most buggy release is Froyo, in Froyo, I cannot use Java NIO selector anymore, but it works fine in previous releases. On Mon, Jun 7, 2010 at 5:25 AM, blahblah...@gmail.com blahblah...@gmail.com wrote: It seems that Android is very buggy compared not only to the iPhone, but to pretty much any other software. It's not just minor bugs either - pretty much every developer will come across many serious bugs. Some examples: - When you run the sdk setup.exe, the very first thing that happens is that it informs you that it can't connect using https, so you have to change the options to use 'http' instead. This appears to be a bug in the .exe rather than any kind of user issue because the https url works fine in the browser and this error seems to affect everyone. Sure, it's trivial to work around (just do a google search and you figure it out in 5 seconds), but the user shouldn't have to do that. It makes it look unprofessional. - When you view a TabWidget in the layout editor it crashes. - Every time you run an app in the emulator, it starts off with the screen locked so you need to press the Menu key. - Various socket bugs (or perhaps all the same bug) related to IOException not happening. Even something as simple as just trying to connect to a remote host that is not listening will cause it to hang instead of immediately returning an error. All of these bugs have been logged for months (some by me, some by other people) with no indication of any fix. At the moment I'm just using the emulator, but I'm wondering if the phones themselves are this buggy or if all the bugs are just in the development environment and emulator. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: My Eclipse 3.5 always lag and have to force close - why?
Doug, I'm surprised you can go for 5 or 6 hours. It grinds to a halt for me in less than an hour. But I guess it depends on what you're doing (Java vs resources). But I'll echo what you said: it's not that the IDE is generally slow, it's something else that is chewing up resources. It's not the emulator, as I can exit that and Eclipse is still the same. As people reported above, you can code all you like, but it seems that if you mess with the resource files, you're doomed.

Just your opinion. False: Preprocessor usage should be eliminated. -Bjarne Stroustrup, An Overview of the C++ Programming Language, page 3, under table Language-technical rules: This concept carried over into the C++ standard committee. Hardly just my opinion. It's not removed, because C compatibility is a higher-priority concern. That's why C++ went to great lengths to mostly remove the need for using it, with inline functions, constants, and the like. Now your just talking specifically about macros which still can be useful and there are somethings that can only be done using a macro. No, I am not. I have nothing against macros -- on the contrary, I met my wife teaching a class on macros. Preprocessors are not the place for them. Lots of languages have macros without preprocessors. Macros are great! I wish Java had them. (They do have their drawbacks, but no on the scale of a preprocessor. And the power of any macros I'd envision is substantially more than is offered by the C/C++ preprocessor). MS tools destroy what Java has to offer IMHO. Only the re-factoring is better for Java. It's all opinion either way. Are you comparing MS C++ tools to Java tools, or C# and friends? Anyway, it's not all opinion. Such comparisons can be done quite objectively. Which tools you prefer to USE is opinion. I think you have to realize that preprocesing is just a tool and isn't to be used to solve all problems. Just because I want a hammer doesn't mean I regard every issue as being a nail. It's very appropriate to handle cross platform issues, hardware issue, diagnostic code etc. All of these issues are very relevant to Android. Sure these issues might be handled differently for a desktop solution where resources aren't as big of an issue. Nobody has shown me a case where you need a preprocessor because of resource issues. Can use, yes, but need, no. It is HIGHLY INAPPROPRIATE to handle platform issues and hardware issues -- it makes porting to a new platform a royal nightmare. Your best shot there is diagnostic code -- and there are better ways, involving post-processors rather than preprocessors. Why force everyone to do it the so called right way? Because of the cost to everyone else of the feature you are demanding. Why not put in every hair-brained feature anyone thinks they'd like to use? Because LONG experience shows, that approach makes for major problems with languages, and makes them harder to use. Trust me -- that approach has had its day in the language-design world. Even a poorly- designed API, not part of the language, can have a major adverse impact on the maintainability of a product. And in extreme cases (but only extreme cases), even personal code- formatting idiosyncrasies can have a negative impact. Let people do whatever they want has, after decades of experience, been found to not be a good idea. A more careful balance must be sought. Why does C# have conditional compile? To accommodate the masses of C programmers that Microsoft wanted to attract, of course! Just because SUN chose not to support preprocessing in javac doesn't mean they aren't behind it. Maybe they chose to support it through tools so that j2me code would still work with j2se? That would make a lot of sense to me. For something they aren't behind they sure put a lot of effort into it. Or maybe they wanted to attract all those C programmers who are used to solving every problem with a #ifdef, and aren't willing to update their approach? Or maybe because the J2ME people actually WERE former C programmers. Language purity is not the only design constraint. Soustroup makes that point himself. Sometimes you make compromises for acceptance. Computer languages are partly human languages, and human languages are a cultural artifact that change slowly. It's also a major compilation performance hit. With a significant amount of pain, you can get Visual Studio to avoid a lot of the reparsing it requires, but the language basically says that to compile any particular program file, you have to parse all the #includes, recursively, processing the same file over and over and over again -- possibly differently each and every time, because INTEGER may mean int in one case, unsigned int in another, and unsigned long long in yet another. And that's a problem for programmers, too. No, I don't mean a problem for me, that a good C++ programmer knows how to avoid the problems. I mean its a problem I've had to help MANY experienced C++ programmers resolve time and time again -- often in vendor-supplied code, rather than their own. Or when two different vendor's include files conflict -- or

[android-developers] Re: Android VNC server
Hi Anil, Thanks for the feedback. Because the client gets the resolution and color depths from the server, we probably don't need to set the resolution on the client (hopefully). I used several vnc clients, and they can all get the resolution from the server, so I haven't tried to force a specific resolution at the client (i could find out how to do so though). I guess if the client didn't get the right resolution/ color depth, it may mean that the server didn't get them right either. Did you check the printout when the server starts up? Does it show the right resolution? If not, can you please turn on DEBUG and DEBUG_VERBOSE and send me the logs?

[android-developers] Re: TouchListener invoked twice
Hi,
It is expected that two MotionEvents will be generated...
First : ACTION_DOWN
Second: ACTION_UP
You can determine which event has occurred using getAction() method.
//===
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
break;
case MotionEvent.ACTION_UP:
break;
default:
break;
}
return false;
}
//=
By the way, if this is a button and you are not planning for something
special, you can use OnClickListener instead of OnTouchListener.
If you use OnClickListener, then one click event will be generated per
touch. And, also, you can activate the button from keypad also.

[android-developers] Re: My Eclipse 3.5 always lag and have to force close - why?
You missed my point, so let me try to make it more clearly. I wasn't absolving the IDE of blame. I'm saying it interacts with the other offenders, if you have them. So if you have a bloated Firefox, for example, the IDE will start to flail much earlier. In that case, you can buy some time (but not eliminate the problem) by killing Firefox. My point about memory is that you will survive MUCH longer on a less limited machine, and upgrading your hardware is another workaround. One that I haven't found financially viable at the moment, but, if you can, definitely try it. And as objectuser points out, not all aspects of the IDE are to blame. Running an emulator worsens things, since that needs memory. Basically, everything you do that needs significant memory, will cause you to start to flail earlier. It's definitely not just Eclipse and Android, however. At 4 GB I can end up in this state with various applications, without anything Eclispe- or Android-related running. I find I have to restart GMail (in Chrome, no less) about as often as often as I have to restart Eclipse. Hmm, what do these two have in common? But that will depend on your usage patterns, too. I will say, it is not just Android programming, and not just resource files that will do Eclipse in. But I do think they worsen it -- either making heavy use of a leaking facility, or adding their own new leaks to the puddle. So my advice is, restart Eclipse often, but also look at the other factors. If you're lucky that will help reduce, but eliminate, the need to restart.

[android-developers] Re: Android preprocessor, //#ifdef...
Notice that they call it low pause, not pause free. There are truly pause-free algorithms, and people who need them. Brokerage systems, eg, need response in the 10s of milliseconds, and a single GC can disrupt a thousand transactions. iSeries had the SPECjbb crown for several years running, first with its own JVM and then with the IBM J9 portable JVM. Was finally displaced by J9 running on other hardware (as the iSeries hardware was getting out of date). Sun did eventually build a special IBM killer box to reclaim the crown by throwing hundreds of processors at the problem (and building hundreds of tuning parameters into the JVM), but it was an artificial configuration.

Concurrency isn't an absolute, and there are various ways of describing the upper bounds on how much delay a concurrent algorithm can impose on other threads. (Your point about stringent response time requirements suggests this may be your issue with calling it concurrent). GC benchmarking is hard work and tricky, and I haven't done it in a long time. I appreciate the anecdotal data; do you have benchmarks behind it? You've aroused my curiosity about the current state. I have generally been more concerned with compatibility in huge code bases rather than performance differences (which can generally be overcome with hardware -- not concurrency, though), so I've mostly avoided non-Sun JVMs when possible. But I like that there are alternatives of increasing quality. Especially given recent corporate history... Thanks.

They're not generally well- designed for LARGE applications (eg, a fast 8-way running a heavy transaction system), or anything with really stringent response time requirements. The IBM iSeries Java implementation ran rings around Sun's, and the newer IBM portable Java implementation runs rings around the iSeries implementation. One of the problems with Sun's GC scheme is the vast number of parameters -- no one understands them, or how to set them for a given set of circumstances (especially if those circumstances vary dynamically).

Sun's GC is good enough that I would hesitate to make blanket statements that it is better than X or worse than X.

[android-developers] Re: Android preprocessor, //#ifdef...
Just a few bullet points: -- I've always thought that C #include processing sucked. Why did they never introduce an #includeonce directive that would have eliminated all the #ifndef stuff to prevent double includes?? -- C macros suck. They obfuscate without really introducing much capability. I've worked on languages that had macros that were their own language -- you could have real variables in them, loop, do most normal programming things. Code was generated via emit statements. With such a macro language you can do some amazing things, and with reasonable use (always a problem, I know) the macros served to clarify rather than obfuscate. -- Post-processing of Java bytecodes is expensive and error-prone, and again obscures the logic. Not that cost should be a criteria, but post-processing is no panacea. -- Yes, one should have to cost-justify including a line-number pseudo-function in javac. But there are a hundred features of Java that don't seem to me to be cost-justified, and several hundred other missing functions that ARE cost-justified. I never have figured out how Sun decided what went into Java and what didn't (though in several cases it appears to have depended on what would hide the deficiencies in their implementation vs expose them).

Just your opinion. False: Preprocessor usage should be eliminated. -Bjarne Stroustrup, An Overview of the C++ Programming Language, page 3, under table Language-technical rules: This concept carried over into the C++ standard committee. Hardly just my opinion. It's not removed, because C compatibility is a higher-priority concern. That's why C++ went to great lengths to mostly remove the need for using it, with inline functions, constants, and the like. Now your just talking specifically about macros which still can be useful and there are somethings that can only be done using a macro. No, I am not. I have nothing against macros -- on the contrary, I met my wife teaching a class on macros. Preprocessors are not the place for them. Lots of languages have macros without preprocessors. Macros are great! I wish Java had them. (They do have their drawbacks, but no on the scale of a preprocessor. And the power of any macros I'd envision is substantially more than is offered by the C/C++ preprocessor). MS tools destroy what Java has to offer IMHO. Only the re-factoring is better for Java. It's all opinion either way. Are you comparing MS C++ tools to Java tools, or C# and friends? Anyway, it's not all opinion. Such comparisons can be done quite objectively. Which tools you prefer to USE is opinion. I think you have to realize that preprocesing is just a tool and isn't to be used to solve all problems. Just because I want a hammer doesn't mean I regard every issue as being a nail. It's very appropriate to handle cross platform issues, hardware issue, diagnostic code etc. All of these issues are very relevant to Android. Sure these issues might be handled differently for a desktop solution where resources aren't as big of an issue. Nobody has shown me a case where you need a preprocessor because of resource issues. Can use, yes, but need, no. It is HIGHLY INAPPROPRIATE to handle platform issues and hardware issues -- it makes porting to a new platform a royal nightmare. Your best shot there is diagnostic code -- and there are better ways, involving post-processors rather than preprocessors. Why force everyone to do it the so called right way? Because of the cost to everyone else of the feature you are demanding. Why not put in every hair-brained feature anyone thinks they'd like to use? Because LONG experience shows, that approach makes for major problems with languages, and makes them harder to use. Trust me -- that approach has had its day in the language-design world. Even a poorly- designed API, not part of the language, can have a major adverse impact on the maintainability of a product. And in extreme cases (but only extreme cases), even personal code- formatting idiosyncrasies can have a negative impact. Let people do whatever they want has, after decades of experience, been found to not be a good idea. A more careful balance must be sought. Why does C# have conditional compile? To accommodate the masses of C programmers that Microsoft wanted to attract, of course! Just because SUN chose not to support preprocessing in javac doesn't mean they aren't behind it. Maybe they chose to support it through tools so that j2me code would still work with j2se? That would make a lot of sense to me. For something they

The more you nail down an API, the more expensive innovation becomes, because the legacy API becomes an albatross over time Again, I would agree that there should be more published, documented, supported Intents for the core applications. Expecting there to be no unpublished, undocumented, unsupported Intents is preposterous. Yes, I didn't narrow my statement sufficiently, and taken to this extreme, it's preposterous. But documented intents (that behave, and continue to behave) as documented, are far more valuable than undocumented ones. The power of the intent mechanism really depends on being able to invoke it from anywhere -- otherwise, you could just do some invoke activity call. Which is what supplying a class name in an intent essentially is. For me, that's really the line of demarcation. Beyond that line, it ought to at least be documented who's allowed to call it! Further, there should be a registry for this information. Something like openintents.org, which I think has about 2/3 of the right idea. Unfortunately, I don't know the other third...but it's probably more sociopolitical than technical. One key component would be getting Google to particpate! This kind of openness enables a whole new CLASS of innovation. Yes the old style of innovation becomes more costly. But when you don't have to build in your own web browser because you can just send an intent -- well, we've seen that that can enable a whole lot of innovation right there. Actually, by my interpretation of the CDD, that's not allowed, unless they are going to have both apps (the original and their replacement). Yes, that's exactly what they should be doing. Personally, I have no problem with this. Carriers would definitely have a problem with this, based on conversations I've had -- they've triggered SDK violations over more minor issues than this. Remember that we're not all that far removed from a world where carriers dictated everything about what was on the deck of a device. It is my considered opinion that, in the larger picture, this behavior is irrational. I can point to various industry parallels -- like how many device drivers PC vendors have have had to write and maintain, far exceeding the supply of competent device driver authors. The quest for competitive edge drives it into this corner, where it remains, but it is far from a cost-effective approach to the basic problem. And I think Apple's app store quite effectively sank the ship underneath that controlled deck idea. (Despite Apple then seizing control in turn). It is one of the reasons I hope that those rumors from earlier this year are true, and that the core applications will be unbundled from the OS and available for update via the Market. At that point, the CDD would need to be adjusted to prohibit replacement-in-place by OEMs, and things will stabilize more. It might even help with the goal of having more published, documented, supported Intents for the core applications. I do not believe the developers have the same responsibility to the platform -- but they DO have a responsibility to the users. And if that attitude is prevalent, in the end, Android will fail. Obviously, I disagree. Developers have no control over the platform destiny. But a rich supply of tools that meet users needs does - regardless of whether that need is approved or not. A Very Direct Impact. Happy customers -- now there's something that will help the platform win! (Carriers still have the power to countermand that, I fear...) The situation would be different if developers had a real say in the platform directions. Then, absolutely I would agree. I think that would really help the platform win, in fact. So I don't buy your pissing-in-the-pool analogy -- and I think you should be able to turn this to your advantage in your efforts to convince hardware manufacturers to behave more sanely. I don't see how. You are asking for device manufacturers to increase their development costs, to support things they're not obligated to support, because third-party developers are doing things they're told by Google not to do. How are device manufacturers increasing their costs by NOT DELETING the core Google app? Is it a matter of license fees to Google? Even better would be to fold in their improvements into the original. This might seem like more work -- but not really, since they would forgo the work of creating all the improvements made by others. Which doesn't help as much as it might sound, but does make enough economic sense that I hear there's even companies selling commercial products based around open source code. Eh? What's that you said? Android is what? What would help third-party developers in this area is if they'd get organized. At
