| 00:45.51 | chomchom | hello |
| 00:46.34 | chomchom | saw halfshell and zhobbs greeting so thought I'd join in |
| 00:46.52 | chomchom | we should make a habit of it. Makes things a little more friendly |
| 00:53.49 | skicson | chomchom: long day isn't it? weren't you on early this am? |
| 00:53.56 | skicson | or maybe that was yesterday |
| 00:54.06 | skicson | it's a just a blur. |
| 00:54.06 | skicson | <PROTECTED> |
| 01:01.18 | chomchom | yup |
| 01:01.32 | chomchom | I'm hard coring it man |
| 01:01.56 | chomchom | I'd like to get through to the second round of the competition |
| 01:02.08 | chomchom | how is your application coming along? |
| 01:02.25 | chomchom | for you to know that I was up, that must mean you were also up! |
| 01:09.50 | duey | i should start |
| 01:10.59 | chomchom | you should start? |
| 01:11.20 | duey | my project |
| 01:11.48 | chomchom | oh yeah you should definetly start |
| 01:11.50 | skicson | no duey. take a few more weeks off. |
| 01:11.53 | skicson | :-D |
| 01:11.54 | chomchom | right now |
| 01:11.59 | duey | good idea |
| 01:12.01 | skicson | right in april. |
| 01:12.11 | duey | uni starts soon |
| 01:12.15 | duey | they will make me do it then |
| 01:12.24 | chomchom | yeah? in uni?! |
| 01:12.31 | duey | yeah its my honours project |
| 01:12.31 | chomchom | wow that would be great |
| 01:12.37 | skicson | chomchom: my app is coming along good. I'm just sitting here wishing there were actually people with handsets that could use it. :-( |
| 01:12.39 | chomchom | you lucky duck |
| 01:12.58 | duey | i should get a decent prototype in 1.5 months |
| 01:13.02 | chomchom | have you shown it to anyone yet skicson? |
| 01:13.15 | skicson | just friends and family so far |
| 01:13.24 | duey | secrets are secret |
| 01:13.31 | chomchom | Whats the feed back so far? |
| 01:13.48 | skicson | "Why can't I have it on my phone" |
| 01:13.48 | duey | well everyone i talked to about my idea is "holy shit thats awesome" |
| 01:14.19 | chomchom | ! well you guys must have some jaw dropping stuff! |
| 01:14.28 | romainguy | dre |
| 01:14.32 | duey | will be if it works |
| 01:14.33 | duey | lol |
| 01:14.42 | duey | complex ideas have complex problems |
| 01:14.53 | duey | 400mhz of problems |
| 01:14.58 | chomchom | I'm really looking forward to the big flood of all these applications |
| 01:15.52 | chomchom | I'm not really into keeping everything secret I prefer just to share and share alike. For the amount of effort it takes in the actual implementaion people don't have time to steal! |
| 01:16.14 | duey | i dont like releasing unfinished things |
| 01:16.19 | skicson | yah, i'm interested to see what other people have come up with. |
| 01:17.14 | chomchom | Are you guys going to release it before the entry date? |
| 01:17.28 | duey | unlikely |
| 01:17.34 | skicson | yah probably |
| 01:17.39 | duey | ultimately i would prefer it to be released when its perfect |
| 01:17.51 | duey | or at least usable |
| 01:17.59 | chomchom | you should try and get something out even if its rough for the sake of usability/bug testing |
| 01:18.06 | duey | yeah |
| 01:18.21 | chomchom | by that time theres no way anyone could steal anything in time! |
| 01:18.36 | duey | yeah but secrets are fun |
| 01:20.18 | duey | ultimately i have to finish it to get honours |
| 01:21.19 | chomchom | well thats ideal |
| 01:21.55 | chomchom | may as well make it a fully commercially viable application. That way you've produced software in your study time that can produce a small income |
| 01:22.11 | duey | well if i release it, it will be open source |
| 01:22.16 | chomchom | or at least establish enough kudos to guarantee you a position somehwere |
| 01:22.24 | duey | yeah its more for kudos |
| 01:23.03 | chomchom | income can be gained from open software it is just gained through bespoke services |
| 01:23.28 | duey | not interested in generating income off the project |
| 01:23.40 | duey | I have a job :o) |
| 01:24.35 | chomchom | well a job is only secure as the next paycheck. A product is an asset |
| 01:25.28 | duey | i guess |

| 01:40.38 | chomchom | has anyone ever seen this error before? |
| 01:40.41 | chomchom | E/AndroidRuntime(650): Caused by: java.lang.RuntimeException: view android.widget.TextView@4004a358 being added, but it already has a parent |
| 01:41.16 | chomchom | It happens when I try to add another Text view to something with a text view |
| 01:41.55 | romainguy | chomchom: Where does the TextView you're trying to add come from? |
| 01:42.28 | romainguy | It seems the TextView is already part of the View hierarchy and you're trying to add it to ViewGroup that's not its current one |
| 01:42.52 | chomchom | ah right |
| 01:43.04 | chomchom | does that mean it is in the wrong activity? |
| 01:43.15 | romainguy | Not necessarily |
| 01:43.20 | romainguy | It just means the TextView already has a parent |
| 01:46.45 | chomchom | ah |
| 01:46.50 | chomchom | I get it now |
| 01:47.16 | romainguy | :) |
| 01:47.52 | chomchom | It was because I was trying to source the textview from an xml file and then programatically assign it to a collection. But I couldn't jus lift it out the xml and then reassign it to a different ViewGroup |
| 01:47.56 | chomchom | thanks |
| 01:48.07 | romainguy | Actually you can do that |
| 01:48.22 | romainguy | but when you use the inflater you should just not pass a parent ViewGroup to the inflate() method |
| 01:48.57 | chomchom | so what should you pass? |
| 01:49.27 | romainguy | null |
| 01:49.34 | chomchom | ah |
| 01:49.45 | chomchom | right yeah that'll work |

| 07:18.36 | jerkface03 | romainguy: any specific preset amount of time before the watchdog jumps in? |
| 07:18.55 | romainguy | jerkface03: What do you call the watchdog? |
| 07:19.18 | jerkface03 | Do you mean what do I mean by the watchdog? |
| 07:19.21 | jerkface03 | the watchdog thread. |
| 07:19.33 | jerkface03 | the thread that checks that you don't tie up a thread for too long |
| 07:19.35 | jerkface03 | ala BREW |
| 07:19.46 | jerkface03 | assuming the same mechanism is being used in android |
| 07:20.02 | jerkface03 | tie up the thread rather |
| 07:20.09 | romainguy | are you talking about the dialog that shows up asking whether you want to force quit the application or keep waiting? |
| 07:20.18 | jerkface03 | bingo. |
| 07:20.29 | romainguy | I believe the current setting is 5 seconds |
| 07:20.41 | jerkface03 | k, 5 seconds should be more than enough time :) |
| 07:20.41 | jerkface03 | thx |
| 07:20.47 | romainguy | er |
| 07:20.49 | romainguy | don't do that |
| 07:20.55 | jerkface03 | ?? |
| 07:21.08 | romainguy | blocking the UI thread for more than ~150/300 ms is bad |
| 07:21.16 | romainguy | since it will prevent user interaction and repaints |
| 07:21.47 | jerkface03 | aye, i don't want to deal with too much threading at this point. i'll refactor it later. |

| 07:48.07 | romainguy | jtoy: tes? |
| 07:48.10 | romainguy | yes, sorry :) |
| 07:48.42 | jtoy | I was wondering about a couple of problems, I'm not sure if its a java or android problem as I am new to java as well |
| 07:49.40 | jtoy | when using bundles, it seems to me like you can't pass objects that are not strings or integers, is this correct, I tried to pass an object with a bundle to different activities, but I got an error saying the object coudln't be marshalled |
| 07:51.17 | jtoy | the class was extremely simple though, class Person; public long id, public String name; } is it correct that arbitrary objects cant be passed through? |
| 07:51.49 | jtoy | here is the class for the code, extremely simple: http://pastebin.ca/894767 |
| 08:01.49 | *** join/#android eton_ (n=eton@ppp-124-121-164-171.revip2.asianet.co.th) |
| 08:02.26 | jtoy | any idea? |
| 08:03.24 | romainguy | how do you try to pass your object to the Bundle? |
| 08:12.03 | jtoy | Intent i = new Intent(this, UserReport.class); |
| 08:12.18 | jtoy | i.putExtra("person",person); |
| 08:13.21 | romainguy | If you refer to the javadoc, it reads: "valueThe data value. Can only be an Integer, String, or HashMap." |
| 08:13.40 | romainguy | the reason for that is that an Intent can be received by another application/process |
| 08:13.49 | romainguy | and this application will not have your Person class |
| 08:14.18 | jtoy | ahh, sorry, I didn't see that part in the doc, so I guess I would use something like a hashmap |
| 08:14.27 | romainguy | yes :) |
| 08:15.13 | jtoy | hmm, thats too bad |
| 08:15.48 | jtoy | I had one more question, is it possible to have list views without a class that extends ListActivity? |
| 08:15.53 | romainguy | definitely |
| 08:16.13 | romainguy | ListActivity is there to make easy to create a screen with a list inside |
| 08:16.23 | romainguy | but you can use a ListView in a regular activity |
| 08:17.25 | jtoy | I have a class that extends Activity, then I just try to display the calhistory with a ListView, when I call: callList.setAdapter(new CursorAdapter(c, this)); I get the error Cannot instantiate the type CursorAdapter |
| 08:17.55 | romainguy | CursorAdapter is an abstract class |
| 08:18.00 | romainguy | it cannot be instanciated |
| 08:18.08 | romainguy | instead you can use SimpleCursorAdapter |
| 08:18.15 | romainguy | or extend CursorAdapter and make your own |
| 08:18.44 | jtoy | what would you recommend, I was trying to use some of the sample code in the docs |
| 08:18.53 | romainguy | try SimpleCursorAdapter |
| 08:19.48 | jtoy | ok I see, I will try that |
| 08:21.08 | jtoy | I have one more question about design, is there any good places that show good practices for accessing data from the db? I've tried to simplify things by making a a helper class for the DB, but i still feel that it is not very good |
| 08:21.34 | romainguy | All I can tell you is to look at the examples and tutorials on code.google.com/android |
| 08:21.47 | jtoy | I know how to design some very simple helper classes in ruby, but im not too sure about java |
| 08:21.51 | romainguy | I work on the UI widgets themselves so I'm not very helpful when it comes to DB :) |
| 08:22.17 | jtoy | ok thanks romainguy , I downloaded a few projects from google already and read through some of them |
| 08:22.43 | jtoy | romainguy: are you building the ui with xml or via code? |
| 08:23.45 | romainguy | jtoy: I meant, I work at Google on Android |
| 08:23.54 | romainguy | I write the *View classes |
| 08:24.00 | jtoy | oh, nice, I see |
| 08:24.19 | romainguy | But when I write UIs I try to use XML as much as I can |
| 08:24.32 | romainguy | because you can create variations of your layouts based on the capabilities of the target devices |
| 08:24.46 | romainguy | like layout/ layout-touch/ layout-land/ layout-touch-port/ etc. |
| 08:24.58 | jtoy | I hope that android will officially support other languages on the vm also, java seems to take out the fun in programming |
| 08:25.12 | romainguy | Oo |
| 08:25.22 | romainguy | You wrote too much Ruby :) |
| 08:25.53 | romainguy | I personally find Java a lot of fun to code with, especially thanks to the help of the various great (and free) IDEs |
| 08:25.54 | jtoy | well for me anyway, I'm sure other people love java , scala seems pretty nice, they already have gotten apps running on android, but the binaries are like 3 megs |
| 08:26.19 | romainguy | Also the problem can be performance |
| 08:26.28 | romainguy | Remember the apps are supposed to run on limited devices like cell phones |
| 08:26.41 | romainguy | Languages like Scala and Ruby are hard to compile efficiently for such devices |
| 08:26.52 | jtoy | yeah, scala has a very small performance hit compared to java as it compiles down to java anyway |
| 08:26.55 | romainguy | And they probably rely a lot on the JIT |
| 08:27.22 | romainguy | But yes, it'd be nice to be able to use other languages |
| 08:27.33 | romainguy | The issue, as you mentioned, is usually the associated runtime |
| 08:28.07 | romainguy | Anyway |
| 08:28.09 | romainguy | off to bed |
| 08:28.10 | romainguy | see ya :) |
| 08:28.14 | jtoy | from the little coding I've done on the iphone, objective C seems to be pretty nice, it does feel pretty dynamci |
| 08:28.16 | jtoy | ok, thanks for the help! |
| 08:28.19 | jtoy | nite |
| 08:28.23 | romainguy | Objective-C is a very nice language |
| 08:28.36 | romainguy | It still has some old things like header files, but I really like it a lot |
| 08:28.47 | romainguy | Especially Objective C 2.0 with the garbage collector :) |
| 08:29.01 | romainguy | (and they have very nice tools) |
| 08:29.04 | jtoy | yeah, i can see the smalltalk history on it, which makes me like it since ruby has history from smalltalk |
| 08:29.18 | romainguy | Java also has a lot of history from Smalltalk :) |
| 08:29.31 | jtoy | true |
| 08:29.41 | romainguy | (I've been trying to like Ruby since 2000 and I still can't; too much Python I guess :) |
| 08:30.06 | jtoy | yeah thats right, you guys love python over there, I started on python, but somehow moved to ruby |
| 08:30.29 | romainguy | To me Ruby always looked like the bastard child of Perl and Python |
| 08:30.42 | jtoy | I think you will like rubinius though, it removes a lot of cruft from the old ruby |
| 08:30.51 | romainguy | But at least it made people love dynamic languages |
| 08:30.59 | romainguy | Just like Java convinced the world that garbage collection was good :) |
| 08:31.12 | romainguy | Anyway, I'm really off to bed now |
| 08:31.18 | jtoy | ok, thanks, bye |

| 10:02.59 | jerkface03 | your only choice might be to poll |
| 10:03.07 | davidw | well, not unless you put a server on android:-) and that's not a good idea IMO |
| 10:04.17 | davidw | xmpp and sms are two ways |
| 10:05.15 | jerkface03 | ya but you said a website to push something |
| 10:05.18 | jerkface03 | sms != website |
| 10:06.53 | davidw | jerkface03, interfaced with the proper things, a web site can push sms |
| 10:07.36 | jerkface03 | sure |
| 10:07.42 | jerkface03 | i thought you were strictly talking about http before |
| 10:08.25 | davidw | nope, just a web site and a phone, with the web site needing to push information to the phone |
| 10:08.39 | jerkface03 | what are you making? |
| 10:08.43 | jerkface03 | if i may ask :X |
| 10:10.02 | davidw | this is for a client, so I can't really say |
| 10:10.18 | davidw | I spend most of my own time on hecl of course |
| 10:10.31 | jerkface03 | hows that going? |
| 10:10.34 | davidw | but that's not really relevant in this case... I just want to be able to push data to a device |

| 10:25.46 | kristian-m | 'just left a comment |
| 10:26.15 | kristian-m | davidw does hecl support symbian v7? |
| 10:26.59 | davidw | well, it's java, so if that runs j2me stuff, then yes, but not natively |
| 10:27.13 | davidw | you can python on that natively, no? |
| 10:27.32 | Stephmw | v7's getting a bit old now, no? |
| 10:29.32 | kristian-m | Stephmw well if you support v7 you've got them all, right? |
| 10:29.51 | kristian-m | davidw that's the problem ;-) |

| 10:31.27 | kristian-m | davidw i thought there is no python support, but I'll try - just got my first symbian device |
| 10:31.43 | kristian-m | Stephmw ;) |
| 10:31.59 | davidw | kristian-m, i'm sure it runs j2me |
| 10:32.12 | davidw | Hecl on Android is much more powerful because you get reflection |
| 10:32.20 | kristian-m | ah i see |
| 10:32.32 | davidw | so mostly you don't have to write new commands in Java, but can write them in Hecl |
| 10:33.02 | davidw | you could probably still do something like that server pretty easily, but you'd have to write it in Java, and call interp.eval(incoming) |
| 10:33.03 | Stephmw | kristian-m: if you get _really_ friendly with the VM vendor and the OEM, you too can get reflection in J2ME... |
| 10:35.46 | kristian-m | davidw okay, i'll start looking into symbian stuff tonight - still hoping to use python in there (and maybe access java functionality somehow...) |
| 10:36.01 | davidw | if you like Python, that's the way to go with Symbian |
| 10:41.34 | kristian-m | can't wait to try it out |
| 10:43.36 | davidw | Hecl can't do *everything*, so writing a native, C implementation for Symbian is sort of out of the picture...I'll just have to stick with Java |
| 10:43.48 | davidw | although I bet 'Jim' would run quite well there.... |
| 10:44.02 | davidw | http://jim.berlios.de/ |
| 10:59.19 | kristian-m | davidw hmm, i'm thinking about writing a section on scripting in my thesis work, so i'll dig into that if i find the time |

| 16:28.05 | zhobbs | davidw, I would think a lot of methods could |
| 16:28.34 | zhobbs | davidw, not for basic types (int,float,double,etc), but for objects (String, Calendar, etc) |
| 16:30.03 | davidw | offhnad? |
| 16:32.48 | zhobbs | hmm..no, just tried one and get a NullPointerException :) |
| 16:33.44 | zhobbs | .equals could take null probably |
| 16:34.05 | davidw | ah, good one |
| 16:40.06 | zhobbs | but actually, it could never be true though Obj.equals(null) |
| 16:40.18 | *** join/#android ArteK (n=Artur@82.177.19.205) |
| 16:40.22 | zhobbs | cause if it was true it would give NullPointerException |

| 18:49.13 | zhobbs | morrildl, that sdk coming out next week? |
| 18:49.35 | morrildl | we don't precisely know |
| 18:49.55 | morrildl | It will be out ASAP, and we are working through the available tasks |
| 18:50.01 | morrildl | er, required, not available :) |
| 18:50.13 | morrildl | so basically it'll get released once our list reaches 0 |
| 18:50.52 | zhobbs | my theory is that the new UI will be debuted at that mobile show in spain, and then sdk will follow |

| 21:48.22 | zhobbs | chadkouse, yep |
| 21:48.38 | chadkouse | cool.. zhobbs your name is familiar -- are you involved with MusicDroid ? |
| 21:48.44 | zhobbs | yeah |
| 21:48.48 | zhobbs | I run helloandroid.com |
| 21:49.06 | zhobbs | I'm not really involved with it, just stuck it up there... |
| 21:49.10 | chadkouse | that's perfect -- I was just trying to get the latest source to run for MusicDroid -- and I have an error that MDSInterface.java is in the way of MDSInterface.aidl |
| 21:49.26 | chadkouse | oh ok who wrote it ? |
| 21:49.34 | zhobbs | I wrote it |
| 21:49.52 | chadkouse | ah ok I thought so |
| 21:49.55 | zhobbs | Just saying that I'm not actively adding features or anything |
| 21:49.59 | zhobbs | what's the error? |
| 21:50.17 | zhobbs | Oh...delete MDSInterface.jaa |
| 21:50.21 | chadkouse | [2008-02-07 16:44:16 - MusicDroid] MDSInterface.java is in the way of MDSInterface.aidl, remove it or rename of one the files. |
| 21:50.25 | zhobbs | MDSInterface.java |
| 21:50.26 | chadkouse | ah.. and then it will be regen? |
| 21:50.50 | zhobbs | yeah, it should regen when you save the aidl file |
| 21:51.31 | zhobbs | if you're compiling from source you'll need that id3 tag jar also |
| 21:51.38 | chadkouse | and voila... |
| 21:51.41 | chadkouse | yeah I had that thanks :) |
| 21:51.53 | chadkouse | hey I was looking -- is there not a horizontal progress bar control in android ? |
| 21:52.15 | zhobbs | nope...you can create one...but there is just the circular one right now |
| 21:52.29 | zhobbs | the next sdk will have a whole new UI, so maybe there will be different widgets |
| 21:52.57 | chadkouse | ok... |
| 21:53.16 | chadkouse | really what I need is like a slider bar... to drag back and forth the position of the playing song |
| 21:53.51 | zhobbs | yeah, would have to be a custom view |
| 21:54.14 | zhobbs | I need to add a custom view tutorial up there... |
| 21:54.16 | chadkouse | can you point me somewhere to learn how tod o that ? |
| 21:54.18 | chadkouse | hehe |
| 21:54.39 | zhobbs | http://code.google.com/android/toolbox/custom-components.html |
| 21:54.50 | zhobbs | And in the Api demos the custom view is the LabelView or something like that |
| 21:57.23 | chadkouse | liek this: http://code.google.com/android/samples/ApiDemos/src/com/google/android/samples/view/CustomView1.html |
| 21:57.23 | chadkouse | ? |
| 21:58.17 | chadkouse | well.. yeah I see what you are talking about |
| 21:58.21 | zhobbs | yeah, but the view isn't implemented in that one |
| 21:58.27 | chadkouse | right..... |
| 21:58.37 | zhobbs | if you look at the layout file referenced there you'll see that it uses a LabelView I think |
| 21:59.13 | chadkouse | http://code.google.com/android/samples/ApiDemos/src/com/google/android/samples/view/LabelView.html |
| 21:59.13 | zhobbs | Also, you might want to look at the "Touch Paint" app under graphics |
| 21:59.26 | zhobbs | that will show you how to handle dragging the mouse |
| 21:59.44 | zhobbs | with onMotionEvent |
| 21:59.44 | chadkouse | I can actually put that off for now.... I just need some simple modifications to what you've done here.... |
| 22:00.02 | zhobbs | that's cool, what you got planned? |
| 22:00.11 | chadkouse | I want to show lyrics while the song is playing |
| 22:00.48 | zhobbs | cool, let me know how it turns out |
| 22:01.19 | chadkouse | Can you help me get started? I'm very new to android (and java really) but I'm pretty good with many other languages.. so I think I just need to kind of "get started |
| 22:01.20 | chadkouse | " |
| 22:01.38 | chadkouse | If I want to add a few lines of text and then update those lines, where do I start ? |

| 22:02.03 | zhobbs | I would recomend the official google tutorial, get's you straight on the terms (activity, view, intent, etc) |
| 22:02.13 | chadkouse | i actually did all of the tutorials and the extra credit |
| 22:02.48 | zhobbs | for MusicDroid the text is all updated in the handler in ControlsMenu.java |
| 22:03.31 | zhobbs | But the handler is only called when the song changes |
| 22:03.46 | chadkouse | ok I see it... |
| 22:03.52 | chadkouse | handleMessage |
| 22:03.56 | zhobbs | yeah |
| 22:04.12 | zhobbs | That's called from a seperate thread which can be seen in run() |
| 22:04.27 | zhobbs | You can't update the UI in separate threads |
| 22:05.17 | chadkouse | where is Run ? |
| 22:05.21 | chadkouse | er run() |
| 22:05.27 | zhobbs | it's in that ControlsMenu.java |
| 22:06.23 | chadkouse | I see.. |
| 22:06.29 | chadkouse | and you update the progress bar every 500ms |
| 22:07.05 | zhobbs | yeah |
| 22:07.18 | zhobbs | you can update progress bar from thread, but not TextView |
| 22:09.44 | chadkouse | ok.... |
| 22:09.55 | chadkouse | so how are you updating the TextView ? |
| 22:10.55 | zhobbs | You send a message to the hanlder and the handler, and the handler runs in the UI thread |
| 22:11.55 | chadkouse | ahh |
| 22:11.55 | chadkouse | ok |
| 22:12.29 | zhobbs | This explains a little about handlers:http://www.helloandroid.com/node/243 |
| 22:15.10 | chadkouse | thanks |
| 22:15.59 | chadkouse | after you create an aidl do you have to do anything to make it create the .java class? trying to make my own aidl file and when I save it nothing happens |
| 22:16.25 | zhobbs | Hmm, it should create the java file |
| 22:18.08 | chadkouse | ah mis-typed the package name |
| 22:33.31 | chadkouse | thanks for your help I'm going to poke around at this for a while.. I'm sure I'll be back later ;) |
| 22:33.44 | zhobbs | no probl, good luck! |
