**** BEGIN LOGGING AT Fri Sep 21 02:59:58 2012 Sep 21 03:00:07 the "item" layout is generated for every "row" from the adapter Sep 21 03:00:15 Well because right now I already have 1 static textview which is for the data so should I add another? Sep 21 03:00:29 we wouldn't call it static if it's for data Sep 21 03:00:38 Its the template then Sep 21 03:00:48 yeah Sep 21 03:01:44 I think it slipped my mind that your prefix needs #'s Sep 21 03:02:30 Yea, incremental values Sep 21 03:02:33 I think your gonna have to format your data ahead fo time or create a custom adapter (ie, extend CursorAdapter) Sep 21 03:02:37 Starting at 1 and goes to an integer Sep 21 03:02:56 that's prob what you want, a custom cursor adapter Sep 21 03:03:12 Cant I add another TextView which is the 'prefix'? Sep 21 03:03:42 yeah, but you want ot assign "cursor position" to it? Sep 21 03:03:54 if Q1 is always Q1, you could just have a field in your data for it Sep 21 03:04:31 if they are ordered in various ways, you would prob use cursor position or something, doesn't sound like something that would be easy to translate into a TextView Sep 21 03:04:45 Its ordered from 1 to fixed value Sep 21 03:05:15 =D Sep 21 03:05:31 Making it easy ;) Sep 21 03:05:33 you reading from a cursor, I keep wanting ot use that terminology buy sying away Sep 21 03:05:39 shying.. Sep 21 03:07:53 Cant I nest a Linear Horizontal Layout inside the listview rows? Sep 21 03:08:33 yeah Sep 21 03:08:48 sorry, I thought you had found your path already Sep 21 03:09:03 just LinearLayout with orientation horizontal Sep 21 03:09:21 Yup and sorry, eclipse is twerking out on my again Sep 21 03:09:27 ; ) Sep 21 03:09:30 making random lines of code, god this pisses me off Sep 21 03:09:36 hehe Sep 21 03:09:57 Android needs a seperate IDE, sick of this crap... Sep 21 03:10:16 * HacDan doesn't use an IDE for android =) Sep 21 03:10:25 because Eclipse is painful. Sep 21 03:10:25 I'm partial to IntelliJ, but I wouldn't suggest that it's leaps/bounds better than eclipse Sep 21 03:10:59 oh it is Sep 21 03:11:05 LEAPS and bounds Sep 21 03:11:11 lol Sep 21 03:11:15 even idea 12's android gui designer is way better than adt Sep 21 03:11:38 if I want to sound credible, I have to be subtle right? Sep 21 03:11:45 I haven't tried 12 yet Sep 21 03:11:47 the ide is only going to be as strong as the weakest link... and the weakest link is eclipse Sep 21 03:12:03 12 is in beta atm Sep 21 03:12:08 and the betas do have issues Sep 21 03:12:13 but I'm building my android rom with it Sep 21 03:12:21 still, I aint afraid of no ghost (translation: I like beta software) Sep 21 03:13:58 ron_frow_: if i write the xml myself, is their UI preview good? Sep 21 03:14:15 also, can it format the xml according to the existing conventions ? Sep 21 03:14:45 ui preview felt slow last I used it (11), I don't care for xml conventions other than my own, so I couldn't tell you Sep 21 03:15:28 God how do I fix this bug Sep 21 03:15:39 I cant edit in the xml editor for more than 1 second Sep 21 03:15:44 its changing everything... Sep 21 03:16:07 close eclipse, make your changes with vim/etc, re-open? Sep 21 03:16:27 not ideal, but if you don't want ot get distracted by it atm Sep 21 03:16:33 I just restarted it 1 minute ago Sep 21 03:16:59 =/ Sep 21 03:18:18 in 12 it is perfect Sep 21 03:18:22 better than adt IMO Sep 21 03:18:40 12 the designer works better Sep 21 03:18:45 you can freely design Sep 21 03:19:03 http://www.youtube.com/watch?v=6BRVzjXpVS4 Sep 21 03:19:10 there really aren't alot of widgets, I don't find the xml much worse than doing html... esp with autocomplete Sep 21 03:19:27 * gutano is downloading 12 Sep 21 03:20:02 ramen noodles with fork or spoon ? Sep 21 03:20:07 fork duh Sep 21 03:20:10 sounds good Sep 21 03:20:17 hrrm.. 12 burried in some hard to find link? Sep 21 03:20:20 :) Sep 21 03:20:36 search on google Sep 21 03:20:48 Well gutano that didnt work, I cant nest the linear layout since the listview calls a textview for the row Sep 21 03:21:03 hunh? Sep 21 03:21:07 use a custom adapter? Sep 21 03:21:12 you can use a complex layout for each "row" Sep 21 03:21:50 how do you think I achieve this Sep 21 03:21:50 http://imageshack.us/a/img716/7200/drag12.png Sep 21 03:21:52 * ron_frow_ thrusts Sep 21 03:22:34 Nice table, damn Sep 21 03:22:35 oh the color scheme *covers his eyes* Sep 21 03:22:45 it does look nice though Sep 21 03:22:49 I didnt come up with the colors =) Sep 21 03:22:53 hehe Sep 21 03:23:03 pre existing software I mirrored in android Sep 21 03:24:39 hehehe "September 11st, 2012", from the IDEA 12 EAP page... Sep 21 03:25:01 they dont care Sep 21 03:25:03 I let them know Sep 21 03:41:16 JakeWharton: I'm looking to have a Service @Produce an event representing the current state of the service, however when the service itself is destroyed it will end up being de-registered from the bus, and then there won't be a producer anymore. Is there some clever pattern you've thought of for producing a default event in this case? or should the consumer detect that the event callback didn't happen during register(this) and then act a Sep 21 03:51:59 spifff: there is something like cwac-servicebus or something if you really need those kind of semantics Sep 21 03:53:57 spifff: https://github.com/commonsguy/cwac-bus Sep 21 03:54:54 i probably would not recommend it though Sep 21 03:56:57 Anyone know about how I can get output like linux lspci/lsusb, on android? Sep 21 03:57:52 Please feel free to pm me any answers or questions Sep 21 03:58:00 g00s: thanks, I'll have a look. just using Otto at the moment Sep 21 03:58:02 install shell commander and run the command? Sep 21 03:58:21 though not sure lsusb is available on android kernel Sep 21 03:58:25 but I think so Sep 21 03:59:02 When I run it from android terminal emulator I get nothing Sep 21 03:59:24 The comma d is there just no data Sep 21 04:00:17 I cannot currently reach my device from my chair Sep 21 04:00:35 might need su to actually get any data Sep 21 04:07:04 I'm rooted running cyano9 Sep 21 04:09:23 Is there a way to compount layouts. For instance, lets say first.xml has the layout I desire for multiple views, however for one situation, I need to add a textbox and label to the end. Sep 21 04:09:57 uh, in the developer console - when you see stack traces for crashes, is there any way to determine which version of android these are for ? Sep 21 04:10:07 Instead of creating second.xml with all of the same items plus the added aspects, can I somehow just have an xml with the added components and then add them to first.xml when desired Sep 21 04:15:11 hmm. my app works fine on 2.2 but crashes on 4.1. let the fun begin Sep 21 04:15:40 epsilonorion, import Sep 21 04:16:14 g00s: do you need it to be tested on a 4.1 device? Sep 21 04:16:21 gutano: I actually got it working, thanks Sep 21 04:16:53 epsilonorion, cool, was trying to find an old writeup by romain... I'll let it go Sep 21 04:17:48 sampullman: thx; special hw is required for it to work though Sep 21 04:17:59 ok, well, good luck Sep 21 04:18:05 what kind of hw? Sep 21 04:18:09 g00s: oh, you got your fleshdroid app working? Sep 21 04:18:34 Leeds: lol, wut Sep 21 04:19:15 huh, seems like content provider permissions have changed semantics between 2.2 and 4.1 Sep 21 04:26:25 what other method is there to stop a EditText from having the keyboard open up, beyond setting a layout to android:focusable="true" Sep 21 04:26:25 android:focusableInTouchMode="true" Sep 21 04:45:34 gotta try and port netbios resolution into android tomorrow Sep 21 04:52:32 might be time to use a sick day, lol Sep 21 04:53:06 hmm, is there a way to communicate to a user … for example - you see a crash in the dev console, and want to let people you are working on it, but the fix will be a few days out Sep 21 04:55:14 seems like there would be too much likelihood of abuse... ie, grumpy devs sending heated defense msgs Sep 21 04:55:51 (I have no idea, just theorizing) Sep 21 04:55:54 g00s: you could check for notifications from a server on app startup, and show a dialog with the retrieved data. Sep 21 04:56:09 I think I've used apps that do that Sep 21 04:56:19 I thought he meant through the dev console Sep 21 04:56:51 oh..well supposedly you'll be able to respond to comments soon Sep 21 04:56:51 well, yeah … basically my app is having problems on 4.1 so i would like to email everyone that had 4.1 and say i'm working on a fix Sep 21 04:57:14 sampullman: oh yeah - heh, where the hell is that ? Sep 21 04:57:31 it will show up before the next i/o i guess Sep 21 04:57:34 dunno, I think some devs can already do it Sep 21 04:59:00 respond, like email? or in the play app reviews? Sep 21 04:59:43 email. the user having the crash hasn't reviewed the app yet Sep 21 05:00:00 I know what you want, and I think google would be silly to allow it Sep 21 05:00:19 not that your usage isn't a valid case... but too much possibility of abuse.. Sep 21 05:01:09 I was hoping to get clarification from sampullman about if this (or the other case) is what he's heard of Sep 21 05:01:57 respond as in, it would be like a 2 comment thread in the comments section of your app Sep 21 05:02:01 publicly viewable Sep 21 05:02:07 that seems more viable Sep 21 05:02:17 they would never give out user emails Sep 21 05:03:02 I imagined that case to be proxied, keeping users anon... but yeah, I would be irritated to get an email from a dev of an app I d/l'd Sep 21 05:25:06 How do I get super.loadURL() available? I'm trying to do cordova android development ... "loadUrl cannot be resolved or is not a field" Sep 21 05:27:55 with cordova it seems you replace setContentView(R.layout.activity_main); with the recommended "super.loadUrl("file:///android_asset/www/index.html");" Sep 21 05:29:54 one tutorial says: 'Create folder xml into the project res folder. Add there plugins.xml and cordova.xml from the package you download before.' Sep 21 05:30:26 apache's says to copy the droidgap xml folder into the package.. I don't have plugins or cordova.xml, only a config.xml there Sep 21 05:30:50 loadURL sounds like a something you would call on a WebView, not familiar with cordova (other than a quick google) Sep 21 05:30:56 Which library do bitmap methods come from? (like nativeHeight, bitmapHasAlpha) Sep 21 05:31:03 libskia.so? Sep 21 05:31:31 I imagine you setContentView a layout with a WebView, find it, cast to WebView and loadURL Sep 21 05:31:34 but I'm just guessing Sep 21 05:31:51 Necrosan: yes Sep 21 05:32:09 thanks Sep 21 05:32:21 gutano, cordova uses html5 for the webview.. so it loads a .html for the layout Sep 21 05:32:44 an .html Sep 21 05:32:54 ok Sep 21 05:33:31 (in the phonegap package there's an example and it has the xml dir.. with res/xml/config.xml) Sep 21 05:33:54 http://marguspala.com/basic-phonegap-android-app-from-scratch-step-by-step/ Sep 21 05:34:29 I was somewhat interested after googling cordova, I'm less interested that you mention phonegap in a similar context Sep 21 05:35:21 cordova is phonegap Sep 21 05:35:44 you mean they are similar in approach? or they are the same project? Sep 21 05:35:46 phonegap gave their entire codebase to apache Sep 21 05:35:46 what about it don't you like? (honestly) Sep 21 05:35:53 so essentially the same Sep 21 05:36:17 the idea that you can fit the capabilities of every native sdk into a common pattern Sep 21 05:36:29 like magic Sep 21 05:36:43 I'm not knowledgable about it, I gathered phonegap was a translater Sep 21 05:37:43 as I'm reading the cordova description, sounds like html5 using browser bindings for some of the HW access Sep 21 05:37:51 perhaps I'm not reading closely enough? Sep 21 05:38:52 I guess some ppl might find it useful to bundle a web page as a locally runnable app... I think i would just make a web page Sep 21 05:43:29 are fine in AndroidManifest.xml right? Sep 21 05:43:35 yes Sep 21 05:45:22 first time I've looked into phonegap... it is to Android/iOS/other as jQuery is to Chrome/Firefox/Safari? (handles the nuances of runtime differences?) Sep 21 05:45:55 my cutting and pasting put bad chars in.. like left and right double-quotes.. Sep 21 05:46:24 ie, nothing that couldn't be done (albeit with more hastle) from each of the browsers by any web app in a browser? Sep 21 05:47:01 it does handle differences between different platforms, so you can get a lot done, supposedly, without platform custom development. I am not sure yet how many features it actually provides. Sep 21 05:47:24 you develop in html5 and javascript... and I believe I've seen someone who uses jquery-mobile + cordova Sep 21 05:47:38 interesting Sep 21 05:47:51 I believe jquery mostly expands the toolset and convenience of coding in javascript, while at the same time handling the browser variations for you as well.. Sep 21 05:48:49 *nod*, but cordova/phonegap don't actually "enable" these things, just make them more convenient, portable.. Sep 21 05:48:50 so if you can trust the jquery project, and don't mind the additional chunk downloaded every hit with regards to web stuff... :) In the case of an app it's not the same type of overhead, but there might be a trust/security issue. Sep 21 05:48:59 still, there are a lot of eyes on it no doubt. Sep 21 05:49:08 Can someone point me a good read on InputStreams? TIA Sep 21 05:49:10 <- fan of jQuery Sep 21 05:49:16 when I import org.apache.cordova.DroidGap -- where does that package come from? Sep 21 05:49:19 and html5 Sep 21 05:49:29 just not sure the mobile browsers are good enough yet Sep 21 05:49:35 esp the embeddable ones Sep 21 05:49:56 is it really using the browser, or is browser stuff now built into the os so it uses os web/html5 calls? Sep 21 05:50:19 I don't really want my package to demand the overhead of loading the android "internet" app Sep 21 05:50:45 it's the embedded browser as I understand it (not Chrome or other app store backend) Sep 21 05:51:21 You should also remember that it is really hard to get same look and feel to your application, as you get with native-code Sep 21 05:52:56 it's not using the browser Sep 21 05:52:57 romainguy: you happen to know libskia's dependencies? Sep 21 05:53:00 it's using a widget called WebView Sep 21 05:53:12 the Browser is built around this widget Sep 21 05:53:16 but it's part of the platform Sep 21 05:53:19 and can be used in any app Sep 21 05:53:23 Necrosan: yes why? Sep 21 05:53:37 Curious Sep 21 05:55:57 when I first read that cordova description, I thought they provided some intermediary runtime that binds to html front end (like Win8/Metro apps) Sep 21 05:57:00 all things considered, I'll stick with my native dev.. Sep 21 05:57:58 * jaggz waits for his 5554 in the emulator which appears frozen at boot Sep 21 05:58:10 odd.. just made it Sep 21 06:00:43 app crashes Sep 21 06:00:48 * jaggz shakes his head Sep 21 06:02:36 jaggz, sorry I forgot about your original problem (was reading up on the tech) Sep 21 06:03:08 I got that resolved .. it was copy/paste errors from a website which replaced double quotes with left-right quotes Sep 21 06:04:14 romainguy you still around? I've been getting sigsegv's in libhwui in jellybean Sep 21 06:04:19 well master 4.0.999999.9999999 Sep 21 06:04:29 browsing around in the Settings app Sep 21 06:04:37 eyah Sep 21 06:05:16 I saw comments you made in a mailing list a while ago saying there was a bug that caused same symptoms fixed in jb Sep 21 06:05:40 seems ui/3d acceleration/drawing related Sep 21 06:05:47 based on the cases I managed to get it to happen Sep 21 06:05:50 that's what libhwui is about Sep 21 06:06:32 aware of any such bugs? Sep 21 06:06:46 there were several in HC, ICS and JB Sep 21 06:06:48 we fixed them all Sep 21 06:06:52 at least all the known ones Sep 21 06:06:58 and fixed a couple more beyond JB Sep 21 06:07:16 if I repo sync master, I should get those, no? I am confused because syncing latest and android version shows 4.0.999999.9999 Sep 21 06:07:32 so close to 4.1 Sep 21 06:07:34 apparently panda support is only in master Sep 21 06:07:36 so close. Sep 21 06:07:45 master is versioned at 4.0.9999 =) Sep 21 06:08:14 ron_frow_: well you wouldn't get the fixes we made after the source drop :) Sep 21 06:08:33 you mean if I picked a specific branch Sep 21 06:08:49 or you are saying you dont have those changes in the master Sep 21 06:09:02 which busybox binary could i download? http://www.busybox.net/downloads/binaries/latest/ Sep 21 06:09:15 how can i see? Sep 21 06:09:22 ron_frow_, I think he's saying the master we see is 5 yrs old Sep 21 06:09:39 makes sense Sep 21 06:09:56 it'd be exceptional to get some of these newfangled bug fixes, even if I have to patch them in myself =) Sep 21 06:10:07 doesnt have to happen immediately or anything Sep 21 06:10:45 I'd love to help but I just don't have the time to wade through our thousands of commits to find which one(s) might fix this issue :) Sep 21 06:11:35 understood, will the recent commits eventually make it into the master? Sep 21 06:11:38 public master rather Sep 21 06:11:52 when the next version of Android reaches the AOSP tree yes Sep 21 06:12:22 shit Sep 21 06:12:25 I hope thats soon Sep 21 06:12:35 you can try to fix the bug yourself :) Sep 21 06:13:02 oh snap, gauntlet thrown Sep 21 06:13:15 anyone could give me a help? Sep 21 06:13:44 your better off just asking, we have no way of pairing you with the person who has the knowledge you need, until you tell us Sep 21 06:14:09 I dont mind digging in, I just dont know NEARLY enough about the libhwui/surfaceflinger/any of that Sep 21 06:14:19 what's the stack trace? Sep 21 06:14:19 I've learned alot about a lot of the android infrastructure Sep 21 06:14:32 dont have that in front of me, but I can get it first thing tomorrow Sep 21 06:14:45 even if I had a you might look here Sep 21 06:14:47 I could dig in Sep 21 06:16:05 romain thats good to know hwo the internal releases work etc... for some dumb reason I just assumed your checkins went into public branch =) Sep 21 06:16:20 not until we publicly announce a new version Sep 21 06:16:26 first time doing android dev - im doing some stuff on the lock screen and i have a couple questions about the service/broadcast reciever layer Sep 21 06:16:26 except for some kernel stuff Sep 21 06:16:28 tools Sep 21 06:16:28 etc. Sep 21 06:16:33 never work in production ;p Sep 21 06:17:16 I LOVE working in production Sep 21 06:17:31 picked up some code online that is supposed to catch screen on/screen off on a reciever and run code in either case, but i'm not sure what's the right way to set up an app meant to run as a service. Can i define something in the manifest to initiate a broadcast reciever at launch time? Sep 21 06:18:22 I am going to have to take a stab at that.. I dont really want ot revert to ICS... I never noticed it there on this hardware, but I got dev/prototypes going to customers Sep 21 06:18:28 in about 1mo time Sep 21 06:18:45 rather i think i need to init the service not the reciever. Looks like service inits the reciever onCreate Sep 21 06:21:14 patched in ethernet support, and looking into some more functionality atm, but I really hope I've got something soon for the sigsegv Sep 21 06:22:38 how do I make a clock which shows the current time? then I need to make a time input area too Sep 21 06:23:37 the clock application source is in source control Sep 21 06:23:54 thank you Sep 21 06:24:03 hey guys can someone tell me why my function with postDelayed only runs once even though its called twice??? Sep 21 06:24:07 http://pastebin.com/4kL4Vg1Z Sep 21 06:26:21 are you sure? Sep 21 06:26:44 250ms increments is... kinda small Sep 21 06:26:59 you realize each of those gets scheduled at the eexact same time, right? Sep 21 06:27:13 so every 250ms you'd get images changing Sep 21 06:27:47 well it runs right the first time tho Sep 21 06:27:57 oh Sep 21 06:28:47 but why wont the function work the second time i call it? Sep 21 06:29:03 the scheduling is delayed? Sep 21 06:29:56 kingargon they are scheduled at exactly the same time for all intents and purposes =) Sep 21 06:30:11 theres no blocking to prevent the second call from scheduling them in almost identical order Sep 21 06:30:12 king, the 250 and second run of 250 run at basically the same time Sep 21 06:30:12 there used to be a web page suggesting how to set up avds for different resolutions / dpis … where the f is that Sep 21 06:30:29 oooh Sep 21 06:30:40 add a button and put the runLights() in it Sep 21 06:30:43 click the button Sep 21 06:30:49 let it run 3 seconds so your lights flickered Sep 21 06:30:54 then hit the button again Sep 21 06:31:02 it should twinkle the lights for another 3 sec Sep 21 06:31:07 king, think about it this way. runlights() returns right away Sep 21 06:31:34 if I had to guess, the runlights() executes for mere ms, and likewise when its done, it sarts scheduling duplicate jobs for nearly the same time Sep 21 06:33:13 so your saying that both funcions are executing but its just that they are on top of each other so it looks like its not working? Sep 21 06:33:19 both runlights run and then at 250ms led1 is set on image 1 and 2, then at maybe 251ms the same images are set Sep 21 06:34:04 okay, thanks guys! Sep 21 06:35:53 it is like telling someone "smile in an hour from now. frown in 2 hours. smile in an hour from now. frown in two hours." Sep 21 06:36:25 s/in an/an Sep 21 06:41:45 a good example for loader while making an async http request ? Sep 21 06:42:05 use an intentservice instead Sep 21 06:42:54 i was hoping by now, i could just create one damn avd, and then change the skin on-the-fly instead of creating a new avd for every dang skin Sep 21 06:43:47 how would this work g00s Sep 21 06:44:16 i dunno. maybe in the avd manager i could just click on the avd and then select a property like 'skin' :) Sep 21 06:44:26 ? Sep 21 06:44:35 ! Sep 21 06:45:03 well, skin and dpi Sep 21 06:45:21 you can change themes on the fly and if its your theme engine you could figure out a way to bundle 10 themes yourself and then turn around and use apk's as well Sep 21 06:45:40 not themes, avd skins Sep 21 06:46:40 oh wait, i guess you can edit that in the avd manager Sep 21 06:47:15 is there a website with the android source examples browsable? Sep 21 06:49:27 jaggz2 its mirrored on github Sep 21 06:49:37 OH OH OH Sep 21 06:49:42 you are saing for emulatoR Sep 21 06:49:58 I thought you were saying skins for apps in separate apks Sep 21 06:50:24 hmm. I mean the sample apps so I can learn from them conveniently while on my phone instead of my desktop Sep 21 06:50:32 ron_frow_: yeah Sep 21 06:51:34 I built a pretty cool theme engine where you just install skin and pick it in the chooser and the app would have same functionality, competely diff ui Sep 21 07:05:04 hi, what is the recommended way to put text in an app Sep 21 07:05:18 text like, some licence/ disclaimer Sep 21 07:05:28 oh god. Sep 21 07:06:16 I hope its not too awful question to ask ron_frow_ Sep 21 07:06:29 just use a damn textview Sep 21 07:06:36 I mean thats a very very open ended question Sep 21 07:07:43 OK, I was asking it from the code maintenance perspective, i.e., would a separate text file in res/raw be better than the text in the xml file Sep 21 07:08:21 I do agree that I made it too open ended and I am sorry Sep 21 07:10:27 it's irc, we are looking for an excuse to be cynical... and it's been a slow day Sep 21 07:10:48 yes Sep 21 07:10:52 heheh gutano Sep 21 07:11:06 You could add it as a string resource. I'm not sure what the recommended maximum size is, though Sep 21 07:11:12 wow, the emu is constantly consuming 20% of my cpu Sep 21 07:11:16 poop Sep 21 07:11:34 poop indeed Sep 21 07:11:36 g00s using intel haxm? Sep 21 07:11:46 no, regular one on mac Sep 21 07:11:50 but again in another xml file I guess sampullman Sep 21 07:11:58 haha Sep 21 07:12:04 haxm doesnt work afaik on mac Sep 21 07:12:09 I've never seen it work on eithe rof my mbps Sep 21 07:12:24 gah all these tools are so fucking ghetto Sep 21 07:12:44 Looney: better than in your layout code. It's either that or in res/raw, like you said... Sep 21 07:13:17 I agree its frustrating that you cant just fire up an emu and have it perform like ios emulator Sep 21 07:13:19 so res/raw is not a bad practice as I thought Sep 21 07:13:20 ron_frow_: i learned the hard way to never leave the emu unattended. i woke up one morning to see it consuming 100% of the cpu; i thought the machine was going to catch on fire Sep 21 07:15:24 Looney: I don't think it's necessarily bad, but it would take more effort to retrieve than just calling getString() Sep 21 07:16:02 so strings.xml it is then ;-) Sep 21 07:16:28 plus strings is easy to localize Sep 21 07:17:58 G'day all, a lot of android code uses the this.* kind of notation eg: this.pm = (PowerManager) getSystemService(Context.POWER_SERVICE); can anyone point me towards a good explanation of the use of this in Android? Sep 21 07:18:23 Mechdave: it is sometimes needed to disambiguate a local variable vs. member. It is not recommended at other times. Sep 21 07:18:30 I personally find 'this' to be just noise. Sep 21 07:18:59 its so you can immediately recognize it as a local var Sep 21 07:19:07 scoped at class level Sep 21 07:19:16 alankila, so basically it is a limiter by making android look for a local variable instead of a global one? Sep 21 07:20:02 eh. There are no globals in java, not in full sense of the word to begin with. It just means "I'm talking about the instance variable (or object member) called pm here" Sep 21 07:20:21 its common in object oriented code... it just syntactic sugar... it just helps you visualize whats going on better Sep 21 07:20:37 and also if you do bad thing slike have a setter with parameter name same as class var Sep 21 07:20:41 this.user = user; Sep 21 07:21:08 that's prob the most justifiable usage I am aware of Sep 21 07:21:10 ron has the specific use case where it must appear. Sep 21 07:21:58 except that you probably shouldnt name your local members the same as your parameter names Sep 21 07:22:12 I use it a lot because I like to have readable code Sep 21 07:22:13 nah, it's pretty common, and eclipse generates it that way. Sep 21 07:22:23 so does intellij Sep 21 07:22:29 if I see this, I dont have to read up and figure out what the scoping is on it Sep 21 07:23:07 I've seen ParentClass.this used in an inner class, I don't fully understand that usage Sep 21 07:23:20 Just 'this' would refer to the inner class Sep 21 07:23:28 right Sep 21 07:23:30 thats so you can access the scope of parentclass from an internal or anonymous method etc Sep 21 07:23:53 rather not the scope but the instance Sep 21 07:24:00 without haveing to explicitly passing the reference Sep 21 07:24:03 gutano: nested classes are not real, they are compiler-generated fiction. Sep 21 07:24:28 gutano: so when you reference to an outer class object, you can write 'Outer.this', and this variable is actually passed to the constructor of the inner class, so it is there Sep 21 07:24:40 interesting Sep 21 07:25:12 listeing for the public service announcement "And now you know" ;) Sep 21 07:25:17 Oh, I have come from procedural C/C++ and it never appears there :) Sep 21 07:25:17 there's other pieces that the java compiler does to pull it off. For instance, it generates accessors for private members for the outer class and uses these transparently. I recommend declaring everything the inner class needs as protected, because it better matches what really happens. Sep 21 07:26:26 there's an eclipse warning you can turn on that talks about each time the compiler must generate accessors to make your code work. Sep 21 07:26:35 Oh dear, I am feeling confused about members and variables :( Will have to do some googling... brb with more questions I am sure :) Sep 21 07:26:53 it's not really relevant, and I doubt there is a performance impact. Sep 21 07:27:12 but if you just out of principle like to know that the code you write isn't going to quite run the way you expected, you might care about that warning Sep 21 07:27:20 alankila, this is a very rare crown to appreciate the insight Sep 21 07:27:23 c++ will fuck your mind Sep 21 07:27:25 s/crown/crowd Sep 21 07:27:41 you learn c++ first, and try to learn java, and you are constantly trying to do things as hard as you possibly could Sep 21 07:28:04 ron_frow_, I am finding that out right now :( Sep 21 07:28:07 learn it after other langs and its a diff world of problems =) Sep 21 07:28:15 I learnt java first, and I find C++ quite pleasant actually afterwards. But I write C++ almost exactly as I would write java. Sep 21 07:28:16 c++ is masochism Sep 21 07:28:16 that probably explains why Java looks so terrible to use Sep 21 07:28:35 alankila - I learned c++ later Sep 21 07:28:44 I understand why its so powerful, because you can do some seriously hacky shit Sep 21 07:28:51 but thats kinda whats so beautiful about it at the same time Sep 21 07:29:08 you can effectively re-engineer the language in a TON of diff ways to do what you want Sep 21 07:29:21 overriding delete operator (wtf?!?) Sep 21 07:30:11 Yes, I found a library called GLM that can provide opengl shading language types and primitives to C++. It's just some headers, and by god, GLSL code compiles afterwards almost without modification Sep 21 07:30:13 I am trying to write java like I would C, if(!understand){printf("pull hair out/n",%c); return;} Sep 21 07:30:24 alankila, yeah, GLM is great Sep 21 07:31:08 Java just feels like an exercise in pain right now Sep 21 07:31:10 not a fan of it Sep 21 07:31:23 there is a lot of hoops java forces you to jump through Sep 21 07:31:32 I am big fan of c# =) Sep 21 07:33:36 I guess I'd really like to see the ultimate flexible compiler and runtime that can just do everything :-p but I guess it's a bit too much to hope for. Sep 21 07:35:19 that being said, java is awfully close to being universal runtime, and there's a ton of languages targeting it already. I haven't really used them because I find java 'good enough', so the motivation isn't there. Sep 21 07:35:55 I wonder if that C# port of Android went any further Sep 21 07:36:20 it might be that llvm would over time become even better runtime target than jvm. It is sort of taking over elsewhere, and might provide better value proposition. Similarly, android did not go with that stuff but sort of replaced it all, for relatively small engineering effort, it seems. Sep 21 07:37:16 you are talking about monodroid? Sep 21 07:37:31 no Sep 21 07:37:33 there's a business doing it, but I've no idea how well it is going for them. Sep 21 07:37:36 they ported android to c# Sep 21 07:37:38 xamarin Sep 21 07:37:46 xamarin does make monodroid Sep 21 07:37:52 https://github.com/xamarin/XobotOS Sep 21 07:37:57 but they actually started something else to prove they could Sep 21 07:38:24 I asked manual de icaza if they needed any help with that project, and mentioned I'd donate my time Sep 21 07:38:27 but never got any resposne Sep 21 07:38:59 pretty nuts they basically ran theire sharpen java->c# converter against android aosp and it build an os that runs Sep 21 07:39:02 miguel Sep 21 07:39:09
