But that assumes that people tag them accurately, so that they CAN be found. That assumption is wildly optimistic: look at how many meaningless variations of the non-descript tag 'android' there are in Stack Overflow. I have yet to find a way to do a meaningful tag-based search in Stack Overflow for an android issue. I doubt there is one. That is why I am not impressed by Google's attempt to shuffle us off into Stack Overflow. Actually, that is only one reason. There are others, but this is the main one.

But just how thorough is this daily walk through? Today, there are 14645 questions tagged 'android'. How do you choose which ones you really look at? Worse yet, some idiot decided there should be ONE tag for 'android- sdk', but then three separate tags for 'android-sdk-2.1', 'android- sdk-2.2' and 'android-sdk-1.6'!

[android-beginners] Re: ATTENTION: Android-Beginners will be permanently disabled on August 9 2010
When I first saw Google announce the existence of Stack Overflow and suggest it for posting questions instead of this forum, I found it mildly amusing. I wondered if it meant Google had plans to discontinue this forum! But then to my surprise, I started seeing not only more traffic in Android Beginners, but even more quality posts than at the time of that announcement. And now I hear Google is going to pull the plug! Come now: do you REALLY think Stack Overflow is that much better than Google Beginners? I certainly do not. Nor have I seen Google, in any of these announcements, make a convincing case that it is. What is more, when I do a Google search to see what the web has on a particular Android problem I am working on, I find useful answers in Android Beginners about as often, maybe even a little more often, than in Stack Overflow. True, the query has to be well crafted to eliminate the dross, but that is situation normal for the Web. Under such circumstances, what impression do YOU think Google is making on the public and the market by this decision? I cannot see it as a good one.

[android-beginners] Re: how to self-close an Activity
I have the same question. And even if they are done with it, I have another question: how do you suppose the user will react when he sees it auto-close? That is, do you really think the user expects this? I am not aware of any other app that does this, the user's expectation is based on these other apps, a de facto standard has emerged. That standard is: let the user close it. Ruby programmers like to talk about the principle of least surprise: the principle applies at least as well to UI design as it does to code.

[android-beginners] Re: adb shell command gives very inconsistent results
This sounds somewhat different from the problems I have seen with adb. So I am not sure how helpful my advice will be, but what I would do is: before ever even entering the shell of adb, make sure that adb can see the emulator with adb devices. Yes, unlike the distinction between emulator and device for the -e and -d options, adb devices will list both real hardware devices (of which you have none) and emulator instances (all of them). If you don't see the emulator instance even after launching the emulator and seeing the home screen, then try adb kill-server followed by adb restart. If that gets adb to see the emulator instance, then go on to adb shell. The one other suggestion I have is to make sure that you are using an uptodate version of adb -- and for that matter, of all the tools.

[android-beginners] Re: screen orientatios
Concerning screen orientation: no, the programmer does not set this. Why would he? The phone sets it, based on what it thinks the orientation is, based on accelerometer and/or keyboard slide. My G1, for example, will usually switch orientation correctly based on how I am holding the phone. But sometimes I have to slide the keyboard out to force the switch. In the emulator, you can choose orientation by hitting Ctl-F11. That is the official command. I have to precede it with Ctl- F12 though. I never did figure out why.

[android-beginners] Re: Application still consumes battery even tough it is closed
Hi, Mark- As I should have expected for someone who did write a good book on Android, I see your knowledge of the Android life-cycle really is better than mine. But I am seeing something else that vitiates this superior knowledge, your habit of stating unconditionally, in a very general form, things that are only sometimes true. For that is what you have done in both issues: 1) the issue of whether or not there is a direct transition to the stopped state and 2) the issue of whether it is true that Back always caused onDestroy() to be called. In neither case is your sweeping generalization justifiable, in both cases you are misleading readers rather than helping them. Do you really want to encourage, for example, Android programmers to fail to handle correctly the case where onStop() is called without a preceding, corresponding call to onPause()? Such programming sounds very careless to me. Even if most of the time (even your 99.999% is an overstatement), the programmer can ignore this scenario, he should be aware that it exists, so then when he needs to take care of it, he knows that he needs to do so. Similarly with the second issue: even Google violates the rule [that onBackPressed() should cause onDestroy() to be called] often enough that your readers are going to be confused if they forget that some apps really do override onBackPressed(), they don't all call onDestroy(). Finally, yes the docs are wrong. I already showed how they contradict each other. And others have found other similar contradictions in the docs. Take a look at my previous posts on this and see for yourself: I provided the direct quotations.

Since those methods are invoked in rapid succession, something else taking over the screen (e.g., phone call comes in) during that window is rather unlikely. Developers should not be worrying about that particular scenario very much, if at all. So other than your own authority, on what grounds do you say that the docs are wrong? The docs are not wrong.

[android-beginners] Re: Application still consumes battery even tough it is closed
This is certainly wrong. Pressing the Back key does NOT cause onDestroy() to be called. It causes onPause() to be called. I have run this in the emulator too many times myself to believe that it does. The application goes into the background, but it remains in memory, on the activity stack. Only much later, if at all, is onDestroy() called. Since most applications do not provide an 'Exit' button/key, and many users do not use a Task Killer, onDestroy() might not be called until power-down (or the next configuration change).

[android-beginners] Re: Application still consumes battery even tough it is closed
That is what the diagram says, yes. But the text of the table says something different: it says onPause() is called when the system is about to resume another activity. But it also says that onStop() may be called when the activity is no longer visible to the user. More importantly, it says that this may happen EITHER because another activity is being resumed (in which case onPause() will be called) OR because it (the current activity) is being destroyed. The implication is that no, we cannot count on onPause() being called before onStop() is called, even if this is by far the more common case. Similarly, the same table says elsewhere that the next state for onStart() can be EITHER onResume() OR onStop(). Again, no stop at onPause(). Finally, I should point out that in http://developer.android.com/guide/topics/fundamentals.html#actlife, the doc we are all following to discuss this issue, it says explicitly that this table offers MORE detail than the diagram (following table describes each of these methods in more detail). That implies that the diagram is incomplete, but the table is if not complete, at least more complete. In a formal spec, the distinction would probably have been 'normative' versus 'reference'. But the Android online docs do not use this terminology. On Jun 26, 4:51 pm, RichardC richard.crit...@googlemail.com wrote: Why both onPause() and onStop()?

[android-beginners] Re: Application still consumes battery even tough it is closed
That link is a good start, and required reading, but I see they have still left in the vague and contradictory language concerning which callback must come next. I am referring to the wording in the state diagram and the table concerning whether onStart() or onRestart() are next, and which callback must follow these. The position in the table makes it look like onRestart() can follow onCreate() preceding onRestart(). But in fact, onRestart() can never follow onCreate() directly: it can only follow onStop(), when the user starts it again (as explained elsewhere at the same link). The above could be dismissed as reading too much into proximity of two items in the table. The same cannot be said for the following: the flowchart-style diagram shows only one possible transition from onStart(): the transition to onResume(). But the text in the table says it can transition to onStop() also. Both cannot be right. So which is correct? How is the Android beginner supposed to know?

[android-beginners] Re: LogCat
That was completely uncalled for and even completely unjustifiable. Why, your own response is more like that of a petulant child than any thing DonFrench said. After all Don French gave an excellent list of reasons why it is better to view DDMS LogCat output in Eclipse rather than running it standalone. What is more, he showed very much the opposite of the petulance you so unfairly accuse him of by patiently detailing all these advantages of viewing in Eclipse. Real software professionals recognize your fix it yourself as the real petulance, since real software engineers understand that such bugs should be fixed by the person(s) most familiar with that part of the code. Code diving is all too often a terrible waste of a good engineer's time. Worse yet, it often causes other bugs down the road, because the 'diver' did not understand the code well enough. This is WHY it should be fixed by the person(s) most familiar with the relevant code, not by anyone who feels the need for the fix. Personally, I hope Google's team will find the time to fix it relatively soon, but I am not going to sweat it if they don't. But I will join Don in saying that it would be a valuable fix, it is likely being given too low a priority -- as often happens even in the best- run projects. Finally, if the Google team does recognize this as a bug, how do we find it in the bug database? Some of us would like to vote for it;) On Jun 23, 6:08 pm, Mikey frak@gmail.com wrote: Spoken like a petulant child - fix it yourself if you think you can do better...

[android-beginners] Re: Way To develope the android application ?
Hi, Mayank- The best two books I have found and read on Design Patterns are not the 'classics' everyone keeps referring too. But if you read either of them, you will see why they are much more accessible than any of the classics, especially the Gang of Four books. They are http://www.holub.com/goodies/patterns/ and http://mindview.net/Books/TIPatterns/. The big advantage of the latter is that 1) it is free, 2) it is a great sequel to another great Eckel book, Thinking in Java, whose 3rd edition is also free. The biggest disadvantage is that he never really finished the book. But it is the former book by Holub that is really good, addressing all the beginner concerns the Gang of Four never address in their books, showing the benefits of using Patterns in real, live code. For a deep understanding of OOP/OOD and Patterns, it has no equal. However, be warned: many of the good practices of pure OOP using Patterns are still not recommended on cell phones, as described at http://developer.android.com/guide/practices/design/performance.html and at http://developer.android.com/guide/practices/design/responsiveness.html. For example, the former warns against creation of many objects, since that still tends to make phones sluggish. But both Eckel and Holub recommend making more objects rather than fewer, even saying that when the existing classes don't do what you want, the 'default' solution is to make an object of a new class. Similarly, somewhere else it was mentioned that inner classes take up more memory than interfaces, but this may already be out of date. That said, one of the many good things one can say about Android is that the list of violations of OOP practices that one must follow for optimal code is far, far shorter for Android than for any previous Java mobile environment.

[android-beginners] Re: debugging the (suddenly) crippling slowness of the emulator
Shall we compare experiences? I regularly run the SDK and emulator not on Ubuntu, but Fedora, which is similar enough. You say even 10 minutes later, you are still looking at boot animation: what I see that is so similar is: about 1 launch in 7 or 10, it gets stuck early on. I never let it go for 10 minutes though;) Instead, if it hasn't got to the home screen (even if it says I have to press Menu to unlock) within 3 minutes, I kill the emulator launch and start it over. I have never seen it fail twice in a row. Yes, it is annoying, but since it never fails twice in a row, I have never felt a very strong urge to debug it further. The workaround is good enough. So how does this differ from your situation? Are you getting the 10 minute failure every time you launch the emulator? Do you still get it after rebooting the machine?

[android-beginners] Re: building the entirety of android 2.2 on ubuntu 10.04
Well, it depends on your understanding of the concept of 'success';) Seriously: the reason for the test you ripped out is that Java 6 introduced a change in the way '@Override' is interpreted, one that does not mesh well with the way Android wants to use it. So you have stuff that compiled, but that is no guarantee that it will actually run correctly! Considering what @Override actually does, however, the build you got will probably actually work, it will only be when trying to compile new Android code that you will have to no longer trust the @Override annotation to correctly flag errors.

[android-beginners] Re: Newbie looking to buy a handset
Or you could buy a G1 on Craigslist for anywhere from $80 to $100 dollars. Expect to pay about $30-$40 bucks to get it unlocked unless you buy it already unlocked. Then once you do the setup with a SIM card in the phone, you should see an offer to upgrade the ROM to 1.6. There is no reason not to accept it. That will give you a fairly up-to-date phone, if with somewhat limited hardware. Cyanogen already has 2.1 ROMs for the G1, but you have to be rather technically savvy to install it, and Cyanogen does not have the license to distribute the Goolge Apps.

Even before running the application under the debugger, a good first step is to look at LogCat in the DDMS Perspective: there will probably be a Java Exception logged there, that Exception is what caused the shutdown.

[android-beginners] Which Widget/UI Component to use for Gameboard?
If I want to create a gameboard, like a checker board or chess board, and allow the user to select a square by tapping on it, which widget should I use? The obvious approach would be to make each individual square a button, but that sounds like too many objects. Is there some sort of clickable-map widget I could use (not 'map' in the sense of Google Maps, of course) to return the coordinates of where he clicked, and let the programmer calculate which square that is in? Should I just do the whole board as one View? Then what API do I call to get the coordinates of the tap? -- You received this message because you are subscribed to the Google Groups Android Beginners group. NEW!

[android-beginners] Re: what happens exactly when android goes to sleep?
All this document says is that when Android goes to sleep, it calls onPause(). But that does not tell what ELSE Android does when it goes to sleep. For that matter, the same doc says that onPause() is also called when another app takes the foreground, so the application developer cannot even rely on a call to onPause() as a sure indicator that Android is going to sleep. Now I realize that the details of what it does when it goes to sleep and wakes up might be subject to change w/o notice, but even so, it is easy to see that the developer often needs to know more than just what that one doc says about sleep and onPause(). A developer also needs to know, for example, that Alarms are still checked while the phone is asleep, and can wake up the phone.

[android-beginners] Re: Why does my app Stop Unexpectedly every time I remove an item from myListView.
I know Justin has been helping people in this forum for a long time,
so perhaps he is tired of repeating it, but since this is a beginner's
group, it is worth repeating the detailed steps for how to do this.
To see the Logcat output in Eclipse, it is easiest to:
1) switch to DDMS perspective: (WindowOpen PerspectiveDDMS)
2) find the tab labeled LogCat on the lower left (assuming DDMS
perspective reset to defaults)
3) front and maximize the tab (the box is on the top far right of this
window) so you can read several lines at once.
Given the symptoms the OP describes, he will probably find a
NullPointer Exception in the LogCat output, whether he is running in
Debug or not.

[android-beginners] Re: Any idea why the following code crashes the app? It happens in calculateGmt()
I'm not seeing enough info for me to run this myself under Eclipse
DDMS and see the exception -- which is probably your best bet for
diagnosing the problem. Or, if it crashes before it waits for user
input, you should use Debug: 1) set a breakpoint by double-clicking on
the bar to the left of the line number in the Java source code editor
2) instead of doing Run As (or ctl-F11 or the corresponding tool),
launch the debugger by clicking on the tool that looks like a bug or
by doing F11 instead of ctl-F11. You can always switch back to DDMS
perspective in Eclipse after that and look in the Logcat output for
the exception.
Or, as either an alternative, or in addition to the above, you might
want to break up complicated lines like
double val = Double.parseDouble(gmtinput.getText().toString());
into multiple assignment statements. That will reveal where, for
example, you forgot to actually allocate memory for the result.

[android-beginners] Re: Any idea why the following code crashes the app? It happens in calculateGmt()
All good points!
In particular, the OP should have told us what the warning suppressed
really was. It might have been the hint he needed to solve the
problem. Or it might have been just another attempt to suppress the
spurious warning messages from Eclipse -- which sometimes says you
need to Override a method you have already Overriden.
And just to connect a few dots: the easiest way to get to Logcat and
search the output is to switch to DDMS perspective, find the Logcat
tab, bring it to the front and maximize it. Then you can delete the
previous contents of the log and just watch the world scroll by. Or
play around with filters, though that is not necessary for this
problem.
It also helps to watch this Logcat output on a known good program run,
so that you can get used to which error message can be ignored.
Unfortunately, even for a program running perfectly OK on the
emulator, we see Java exceptions and other error messages in Logcat.

Second thing I noticed is that hideous @SuppressWarnings thing In my
opinion if you need to do that then you need to rethink what you are doing.
Last, but not least, check the logcat output when you get a crash... it will
tell you more about why it is crashing.

[android-beginners] Re: Optimizing drawing on a canvas
Are you calling the Drawable method setBounds()? Android Graphics will check to make sure the rendering is inside this rectangle before actually putting pixels on the screen.

[android-beginners] Re: How often does an activity run?
It is most definitely not a zombie process. A zombie process, by definition, is one not even the shell command 'kill' can kill. The process you just described is still able to receive events -- and will the next time the OS decides to call onDraw. It is Android that decides when to call onDraw(). However, you can tell it to do so by calling postInvalidate() or invalidate() as described in http://developer.android.com/guide/topics/graphics/index.html On Apr 18, 11:37 pm, BobG bobgard...@aol.com wrote: If we run a simple little hello world program that just puts some text in a textview, I see the the onCreate runs, and I guess it calls ondraw once, then it sort of returns to the os, and if we have registered a sensor changed or an onclick listener, we can read the sensor and call invalidate and the os will call ondraw again, and it all is usually 'fast enough'. But my question is: Does ondraw ever get called again? Or is this now a 'zombie process' that will just sit there taking up memory until we kill it? -- You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: Android Emulator don't show up (Linux Fedora 12 x86_64)
I didn't have to follow that many steps to get it up and running. Yet
I am running under Fedora, too.
For example, 'yum' will allow wild-cards, so that where he ran many
yum commandlines, I needed only one. Nor do I remember having to
twiddle with permissions.
Then again, I am still running SDK v. 1.6. I never felt a compelling
need to jump to 2.1 when most phones are still running 1.5 or 1.6
binaries anyway. Until recently, it has been easier to find books and
websites documenting how to use SDK 1.6 anyway.

Hello,
I just installed android 2.1 on Fedora 12 x86_64 and it's working for me.
1st step, I followed other peoples advice and installed the following rpms:

Hello,
This is wrong! Pulse Audio is new, not old. People are using it more
and more not less and less.
It is working better all the time on Fedora 12. Originally I had
problems now and then with Pulse Audio but not in the last few
months. In fact, my bluetooth headphones work best under Fedora 12
than under Vista 64 Ultimate or XP Pro.
It is used now with Gnome, MS Windows, and the Palm Pre.
Try to fix the problem rather than strip down the OS.

[android-beginners] Re: Is there a concept like DLL in Andoirds?
So the short answer to his original question, whether or not there is a 'DLL concept' in Android, is 'no'. If he really wants to, he can use the NDK as you suggest, but that sounds like a lot of custom work for trying to support a C/C++ paradigm in a Java world, an approach that is likely to offer more pain than profit. Android is based on Java, it is only to be expected that the Java way will be more natural.

[android-beginners] Re: R.id cannot be resolved
Yet another option is to turn on ProjectBuild Automatically (put a check in the checkbox) in Eclipse. This will make sure R gets regenerated when it should. Unfortunately, it also generates a lot of spurious error message while you are typing in new code, which can make Eclipse run slower and slower... But I have had no problems with such slowness ever since upgrading from 512M to 2G of RAM. Before this, I would turn Build Automatically off when it got too slow, but leave it on the rest of the time. BTW: the install instructions do say to install Eclipse leaving this turned on. My guess is that their motive for this is that they know they have a bug somewhere in keeping track of build dependencies -- a but covered up by leaving Build Automatically turned on.

There are lots of alternative tutorials. But they tend to be even more out of date than Google's.

[android-beginners] Re: illegal characer in URI ?
Judging from all the sample code ignoring the recommendation, I'd say not many people did know. That is why I posted the quote from the API docs. OTOH, it is a mild nuisance that URI throws URISyntaxException, which isn't even an IOException. So I suspect the desire to avoid dealing with this is the reason so much sample code ignores the recommendation. But professional quality code should not avoid this. It should follow the recommendation and deal properly with the exception. On Feb 14, 4:23 pm, Kevin Duffey andjar...@gmail.com wrote: Good info Indicator..

[android-beginners] Re: Emulator takes too much time to show up - any solution?
Unfortunately, such a small setting for SD card size is not always an option. It has already been pointed out by others in this forum, for example, that to get the Google Maps examples (from the tutorial etc) to run, you need an SD card greater than 8M. I use 10M for each AVD intended for use with Google Maps. And I know it has been said often enough already, but I will say it again, because it is such an important point: because the emulator is so slow to load, it really is a good idea to load it once and keep it running for as long as you can, quitting and reloading only as a last resort. Unless, of course, it really is true that your system gets slower and slower the longer you do this. But that is unusual. If that is really what is happening, then yes, you need to check your system settings to make sure enough real, physical memory is allocated to the emulator. And be moderate with SD card size. 10M should do fine, smaller if Google Maps not needed. On Feb 8, 5:20 pm, BobG bobgard...@aol.com wrote: Check the pagefile size in task manager.

[android-beginners] Re: Can't create new class in Eclipse (Google Map View official tutorial)
As far as I can tell from your description, I went through the exact same steps when I did the HelloGoogleMaps tutorial a few days ago, and everything worked fine. The new file was created and placed right where it should be when I clicked. The only differences I can see are things that should have made no difference, i.e., the name was HelloGoogleMaps, not HelloMapView, and I am running under Fedora11, not WinXP. Or is the different name the problem? The tutorial I did really was http://developer.android.com/resources/tutorials/views/hello-mapview.html, it really does want you to name things HelloGoogleMaps, and NOT HelloMapView, even though the name of the tutorial is Google Map View. Did you do http://developer.android.com/guide/tutorials/views/hello-mapview.html instead? They are very similar. But somehow, this does not sound likely, since you mentioned you get the same error with a non Android project.

Thanks for the suggestions. I thought I already tried the Refresh, but I will try that again. I did not try the Clean Project, so that will be worth trying, too. But for now, I have to admit my enthusiasm for this particular tutorial is somewhat dampened by the problems I found running it under SDK 1.5 as described in http://stackoverflow.com/questions/2180966/bug-running-android-tutorial-hellotabwidget-under-sdk-1-5-setcurrenttaggetinte/2182310#2182310.

That's not entirely true. You can develop apps in the 2.1 SDK that work on Android 1.5. You just need to adjust the minSdkVersion in your AndroidManifest.xml as detailed here:http://developer.android.com/intl/fr/guide/publishing/versioning.html... The thing that matters is that you test your product on Android 1.5 (either on a physical device, or using the 1.5 emulator) before shipping it. There is functionality available in the latest SDK that simply won't work correctly on earlier versions of Android, and you need to iron these out before the app will work correctly on the earlier versions. Regarding the original question: creating a drawable/ directory is not a kludge, you can delete the drawable-hdpi/ etc directories and stick with just drawable/ if you want. However, doing this should not be required. You are able to put all your images in drawable-hdpi/ and they should all be seen by Eclipse. The fact that this was not happening for you suggests that you dropped the images DIRECTLY into the directory, and Eclipse simply did not find them for some reason. You should try right-clicking on the project in the Eclipse package explorer tree, and selecting Refresh. If that doesn't get rid of your error message, then try the Project - Clean... option in the menu bar to re-build your entire project - occasionally, the new files are found, but your R.java is not updated for some reason. -- You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] 'drawable' vs. 'drawable-hdpi' in Online Tutorial
It seems the online tutorials have not been rewritten to reflect Android 2.1. For they still refer to 'drawable' and 'res/drawable', but when I create a new project for 2.1 using the wizard, I do not GET any such directory. Instead, I get 'res/drawable-hdpi', 'res/drawable- ldpi' and 'res/drawable-mdpi'. Now for some tutorials, I have been able to get by by putting files in 'res/drawable-hdpi'. But for the TabLayout tutorial, http://developer.android.com/resources/tutorials/views/hello-tabwidget.html, this does not work. I still get the error message (on completion of step 3) R.drawable.ic_tab_artists cannot be resolved. The files ic_tab_artists_grey.png and ic_tab_artists_whit.png really are in res/drawable-hdpi. I also tried changing the name 'drawable' to 'drawable-hdpi', but Java did not like the '-' in the name (no surprise). So how are we supposed to get this to work? Go back to 1.5? Surely there is a better way. Just for clarity's sake, the line of code I get the error on is: spec = tabHost.newTabSpec(artists).setIndicator(Artists, // res.getDrawable (R.drawable.ic_tab_artists)) .setContent(intent); in HelloTabWidget.java.

Out animation, but not to display the animation itself.
I would study the Google tutorial on Tween Animation (or the
immediately following section on Frame Animation) at
http://developer.android.com/guide/topics/graphics/2d-graphics.html#tween-animation
to figure out what went wrong.

I am glad you solved the problem. Now as for which team should check it out: this sounds like an emulator issues, not an Android issue.

[android-beginners] Re: Android development on Netbeans
There is a netbeans plugin for it, but I could never get it to work. A lot of other people have had the same problem, so I would not recommend wasting time on it. Eclipse has its own problems, but since the entire Android development world is using Eclipse and the ADT plugin, it is and will always be better maintained and supported than the NetBeans plugin. That is why een though I consider myself a NetBeans person rather than an Eclipse one, I downloaded Eclipse and learned the basic in order to to Android.

[android-beginners] Re: Hello World / Emulator Problem
Until when? How long should the user continue to wait before he can conclude that something really has gone wrong? Remember: he said the message waiting for Home android.process.acore was STILL displaying on the screen. Can we count on this message to be accurate? Sure, I know that the emulator takes a LONG time, even on a fast machine. But sometimes the launch really does fail, and the user needs a way to tell. My own experience has been: 1) it takes a very long time, and paints the word 'Android' on the screen in two different fonts 2) sometimes, but not all the time, I have to unlock the menu 3) sometimes, but not all the time, execution passes directly to the application, sometimes I have to launch it myself. I don't remember what was displaying in the console window in all these cases: that is why I ask which messages we can really count on in that window. It seems pretty random which I get in 2 and 3.

[android-beginners] Re: Eclipse Galileo Build path 1.6 Win XP Newbie
It is not just you. I have been having the problem off and on ever since I first downloaded Eclipse. But for me, the workaround you describe does not always work. I just flail around trying different things until the system finally decides to launch the emulator despite the build errors and then rebuilds the file it previously complained was missing. Usually that flailing included not only restarting Eclipse, but even deleting the project and starting all over (using lots of copy-and-paste). One suspect I only recently though of: all this time I have been running Fedora 11 with the default Java, which is 'Open Java'. (Previously it was Ice Tea Java). But Eclipse has not been tested with Open Java. It has been tested with Sun Java (and one variant of it?). I have now installed Sun's JDK 1.6.0_17, but I haven't used it long enough to verify that this has any effect on the problem.

[android-beginners] Re: New Android Project in Eclipse - Build Target Section Not Selectable
I think this is just random Eclipse/ADT flakiness. I had (what sounds like) the same problem when I tried to install the WinXP Galieo build of Eclipse (and Android 1.5); I followed all the steps exactly as in the directions until I could not, because the directions insisted there would be a choice of build targets -- when there were clearly none. That was when I gave up on the Windows version, loaded Eclipse under Linux (Fedora 11) and have not seen it since. I wish I could guarantee such smooth sailing to anyone else who makes the switch...

[android-beginners] Re: send String to pc using wifi
That depends on what you mean by send a string. Usually, people don't just send a single string and then stop there. Instead, they implement a client on one device and a server on the other. So in your example, you would need to open a socket on the PC, too, and get the OS to 'listen' on its end of the socket. In fact, the wording above reveals the ambiguity plaguing a lot of talk about 'sockets'. You create a data structure called a 'socket' on the phone before you have the corresponding structure on the PC, and you do not yet have a true socket yet: you have a true socket only when you have an open port and an application running on both ends of the communication path known as a 'socket'. Now rather than write a special application just to receive a single string, I suggest you run 'telnet' on the PC, and then send to the phone from whatever port you chose as a command line argument when you launched telnet. Don't forget to open up the port in the firewall, too. You will probably have to open it up even if you use the standard telnet port, since this is usually left closed to prevent people hacking into your system by using telnet. Which means you should close the port in the firewall when you are done with this experiment. But the important point is: your PDUs will disappear into thin air if you don't do these things before calling a write routine on the socket.

[android-beginners] Re: Error in helloandroid tutorial
I haven't seen that error message. But since the name of the application in the tutorial is certainly not Android Keyboard, you can safely force close it. My guess is that you should go ahead and do that, and then look for the application (Hello Android or HelloAndroid) you made during the build and run that. Normally, that application would run anyway, without waiting for you to start it. But that does not appear to be happening, since you are getting this other application in the way. But all this is only a guess. If you are lucky, after a little while you will see more knowledgeable answers in this thread.

declaration like Random mRandGen = new Random();,
mRandGen.nextInt(9) +1;
to return a random integer from 1 to 10.
Code w/o casts is generally better than code with casts. Unless, of
course, it resorts to drastic contortions to avoid the case. But such
is not the case here.,

Casting to an integer removes the fractional portion. Casting has a
higher operator precedence than multiplication or addition, so happens
first in your full expression. Parentheses could be used to alter when
the cast happens, however. Like this:
(int) (Math.random() * 9) + 1

i = (int) Math.random() * 9 + 1;

always i is getting 0 and goes to infinite loop, why so ?

[android-beginners] Re: detect if there is a connection to internet
Now maybe Marton will figure it out, he was, after all, the person who asked the question. But I cannot figure out how to tell whether the phone is connected to the Internet from NetworkInfo, not even from the more detailed version, 'NetworkInfo.DetailedState' Rather, the questions this object answers are just a little different: on the Wifi net, it tells you when you have a 802.11 connection, on the phone network, it tells you when the phone network is idle/ connected/disconnected. But I see no way to differentiate between, say for example, 802.11 MAC level connectivity and 'Internet', which has to mean at least IP if not TCP level connectivity. After all: the text does say, Describes the status of a network interface of a given type (currently either Mobile or Wifi). Both of these interfaces can return CONNECTED without any connection to the Internet being available. Hopefully, that is not too common in the Mobile case, but it certainly is common in the WiFi case: it is distressingly frequent that you have connectivity to the local net, or even to the local access point -- and no further. Now maybe this is good enough for Marton. But the question he originally asked was about Internet connectivity, which really is different.

The answer to your question why java 1.5 is at http://groups.google.com/group/android-developers/browse_thread/thread/4e3d0af6c71a4eec/05e0cef64d4d1743?lnk=gstq=java+1.5#05e0cef64d4d1743. If the SDK docs you read say otherwise, it is probably because they were not updated. Or it could be because the above cited post really only applies to platform builds... Thanks for answering the question about which perspective you are using. If you cannot workaround this Eclipse bug by choosing a different perspective (one with no ProblemView), then I suggest you describe the problem to an Eclipse forum. Or it may be time to do as you suggested yourself earlier, re-install Eclipse. And then update it. Of course, I hope that is not necessary. But it is an Eclipse class that is not being found, so this is an Eclipse problem, not an Android problem. Finally, I doubt the problem will be solved by using Java 1.5 (the main reason to use 1.5 is '@Override'), but since that is such an easy thing to try, you might want to try that before re-installing.

Why, yes. The blog post is good. But it inspires me to wonder: what is Guy's native language? I ask because he gave a classic learner's mistake confusing the gerund with the participle. I refer to: Since everything happens on a single thread performing long operations, like network access or database queries, on this thread will block the whole user interface. As it stands, 'performing' must be a participle, which leaves like network access or database queries dangling without a role in the sentence. But with moving just one comma (and adding the clarifying parentheses), it now parses correctly as a gerund, to read: Since everything happens on a single thread, performing long operations (like network access or database queries) on this thread will block the whole user interface. I am sure many readers of this forum will find that version of the sentence much more memorable as well as easier to follow.

[android-beginners] Re: LinearLayout View Tutorial, weight behavior
Hi- The most likely explanation is that you did not modify the weight you thought you did. The very first occurrence of the layout_weight attribute is in the outermost LinearLayout, so it applies to the entire screen, not to the upper half alone (the color bands). To change the weight only for the latter, you need to change the SECOND occurrence of the layout_weight attribute. Of course, that still doesn't explain the reverse behavior you described, but at least it is a start. Now concerning your background: it is impressive that you have made this much progress in Android w/o an OOP background, but you will make it much easier on yourself if you take the time out to learn at least the elements of OOP using Java before putting too much effort into Android. All the Android documentation and tutorials do assume a fairly high level of familiarity with these elementary facts about Java.

That said, I'm doing as suggested at the end of the LinearLayout View tutorial and modifying the weight values to see how it affects the size of the columns and rows. The structure seemed very simple, so it seemed obvious that modifying the first weight (the top half) to 2 should give the top section 2/3rds of the screen and the bottom only 1/3rd. Instead... it appeared to be reversed... the upper area had become the smaller third (this is in the emulator... I do not have actual hardware yet).

Or so I thought on first reading. But no, I was misled by the small frame in the tutorial. Now that I have it running in the emulator myself, I see the exact same thing you saw. OTOH, the behavior is closer to what is to be expected (based on the tutorial) if you change from the default only the weight in the green band, changing from 1 to 2: then the green band is approximately twice as big as the red and blue, but the yellow falls somewhere in between!

The very first occurrence of the layout_weight attribute is in the outermost LinearLayout, so it applies to the entire screen, not to the upper half alone (the color bands). To change the weight only for the latter, you need to change the SECOND occurrence of the layout_weight attribute. Of course, that still doesn't explain the reverse behavior you described, but at least it is a start. Now concerning your background: it is impressive that you have made this much progress in Android w/o an OOP background, but you will make it much easier on yourself if you take the time out to learn at least the elements of OOP using Java before putting too much effort into Android. All the Android documentation and tutorials do assume a fairly high level of familiarity with these elementary facts about Java.

I'm currently a C developer (not C++ unfortunately... so no experience with OOP) who writes homebrew for the nintendo DS. I'm exploring moving away from that platform and towards the Android. That said, I'm doing as suggested at the end of the LinearLayout View tutorial and modifying the weight values to see how it affects the size of the columns and rows. The structure seemed very simple, so it seemed obvious that modifying the first weight (the top half) to 2 should give the top section 2/3rds of the screen and the bottom only 1/3rd. Instead... it appeared to be reversed... the upper area had become the smaller third (this is in the emulator... I do not have actual hardware yet). I tested the same idea on the color columns and the more expected result occured... the columns with greater weight were now wider and seemed to take up the correct fractional area of the screen. Any particular reason for this behavior? Thanks everyone, Jeremiah -- You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: changing a package name
Explains more about packages and libraries. More than what? As you admitted, this is really a Java question, not an Android one. Almost any source will explain more about packages and libraries than the Android docs, since they assume it is understood. Or are you looking for something that explains more than your basic Java reference -- whatever that is? Under such circumstances, I am afraid we can only give you vague answers here. But I hope you will find some benefit in even such a vague answer as to refer you to the Java tutorial on Packages, namely: http://java.sun.com/docs/books/tutorial/java/package/index.html NB: the tutorials go on and on glowingly about Java 1.6, but you really want 1.5 for Android. But for this tutorial, the difference is negligible. Finally, since this is, after all, an Android forum, please consider learning the Android approach to communication between packages and applications: instead of moving source code between packages and libraries, use Intents (or a similar IPC scheme). Really finally this time, we do not know enough about the particulars of your situation to say what the solution should be. But it may very well turn out that IPC is the way to go rather than moving code. You may even decide to move some code but handle the rest with IPC. Good luck.

Now I want to link this with another routine say a sound recording activity. They are in different packages and different projects. AChartEngine has lots of Lib's and Referenced Libraries, so it's easier to move the other stuff there. However the charting demo has the demo package name and the demo project name. What is the best way to move these things about? Is there a sensible text which explains more about packages and libraries etc?

[android-beginners] Re: how to remove completely the SDK and ADB
Are you running them under Windows or Linux? Windows has its uninstall somewhere in the Control Panel, and most distibutions of Linux have their own package manager for the uninstall (e.g. apt-get, yum). And did you install the SDK using the Eclipse package manager (supported since 1.6), or did you download the zip file and install it yourself by unzipping it and setting paths in Eclipse? If the latter, then SDK removal is the reverse of installation. But there's not much point in reverting Eclipse variables if you are going to remove Eclipse,too. That said, I have been thinking about reinstalling both also, but have been warned that it will change nothing, Eclipse really is that buggy: ( On Nov 11, 11:55 am, Marton Kodok pentiu...@gmail.com wrote: Hello, I think there is something wrong with my Eclipse and SDK installation.
