**** BEGIN LOGGING AT Sat Apr 25 02:59:59 2015 Apr 25 03:00:41 Guess I'll ask here. I'm trying to get inter app communication working, but bindService returns false, and onBind never gets called. I'm working in eclipse. Any ideas? Apr 25 03:00:41 you need to be identified to join the dev channel iirc Apr 25 03:00:55 sorry about the copy-paste trash Apr 25 03:09:34 meh, i wish i didn't have to pay another $25 to xfer app from 1 account to the other :( now i have 2 developer accounts Apr 25 03:13:36 soooo this channel is pretty dead. Is there a better one? Apr 25 03:14:24 ravenreborn: #android? Apr 25 03:14:33 V_V k Apr 25 03:14:58 its friday evening, so yeah it gets quiet for the weekend Apr 25 03:15:10 ravenreborn: or maybe ask in #java debugging advice Apr 25 03:15:56 for debugging advice* Apr 25 03:16:33 <_genuser_> g00s: are you implying that nerds party too? Apr 25 03:17:09 everybody needs a break from fighting against android all week :) Apr 25 03:18:08 <_genuser_> heh. I'm also taking a little break and testin gout my new mxl v250 mic that I just bought Apr 25 03:18:39 <_genuser_> so much better than the 910 that I have. Well not better, better suited for recording acoustic Apr 25 03:19:33 not familiar with that one, actually haven't played in a while. i miked my amps with sm57s Apr 25 03:19:43 but those were boogie cabs Apr 25 03:20:55 my 12 string i just put through a bbe482 and that went into the mixer Apr 25 03:21:33 maybe through some TC stuff if i wanted some reverb/chorus Apr 25 03:22:36 _genuser_ are you using a compressor ? Apr 25 03:23:58 i basically sold all my rack gear as i was convinced it was all going to wind up as an iPad app eventually Apr 25 03:31:58 widgets are hard Apr 25 03:32:22 I just want to update it every 15 seconds or so Apr 25 03:33:32 alarmManager.setInexactRepeating(AlarmManager.RTC, System.currentTimeMillis(), context.getResources().getInteger(R.integer.widget_update_period_millis), pendingIntent); Apr 25 03:33:38 that alarm never seems to fire... Apr 25 03:34:46 R.integer.widget_update_period_millis = 5000 Apr 25 03:35:20 make sure your pending intent is unique Apr 25 03:35:45 what exactly makes it unique? Apr 25 03:35:52 google pending intent unique Apr 25 03:36:00 you add like the hash of the uri or something Apr 25 03:38:40 <_genuser_> g00s: oooh bbe? shmancy! I just plug it into an m-audio interface. Apr 25 03:38:57 <_genuser_> g00s: I used to have an ART tube preamp but it burnt out and I haven't bought another. Apr 25 03:39:35 <_genuser_> the rack stuff is hard to collect unless you have a studio with dedicated space and you can keep it up to date. AND you use it. Apr 25 03:39:57 <_genuser_> I've heard guitarists ditching pedals and going with racks, but that sounds overly complicated in being dynamic. Apr 25 03:40:25 Can ok http make a put request? Apr 25 03:42:00 pretty sure the pending intent is unique... Apr 25 03:42:04 Intent intent = new Intent(context, OneHourWidget.class).setAction(OneHourWidget.ACTION_ONE_HOUR_UPDATE); Apr 25 03:42:04 return PendingIntent.getBroadcast(context, alarm.getWidgetId(), intent, PendingIntent.FLAG_UPDATE_CURRENT); Apr 25 03:45:08 _genuser_ long time ago, i worked for ART. Apr 25 03:45:44 <_genuser_> g00s: :) so tell me what you think of the ART tube preamp. I read you can replace the tube and it should give some decent tube affect. Apr 25 03:46:09 it was long looong ago, when they were still making digital effects. i think they just basically gave up Apr 25 03:46:47 at that time their main competitor was alesis Apr 25 03:46:53 <_genuser_> I haven't ever owned a tube amp and I hear all teh guitarists rave about them. problem is you have to let one breathe and crank it up. Apr 25 03:46:59 <_genuser_> you can't do that when you live in a house with others. Apr 25 03:47:42 <_genuser_> plus you need silence, glitch free electric circuit, and tons of patience for mic'ing those. So I've moved DI'ing. Apr 25 03:48:01 <_genuser_> either DI it, or record clean and amplitube or some such it. I have some free marshal plugins. Apr 25 03:48:22 <_genuser_> but mostly, I"ve just moved to doing electronic music. And some pop stuff here and there where guitar tone won't matter. Apr 25 03:51:12 yeah, its all a pita Apr 25 03:51:38 <_genuser_> I mean you question your interest in music when other guitarists do all this and you sit back and say it's a lot of work. Apr 25 03:52:02 <_genuser_> but I think I'm over it. I enjoy both, so I mostly do electronic. But I do enjoy recording the acoustic and playing it. Apr 25 03:52:20 getting that tone you want on guitar is so elusive, yeah Apr 25 03:52:24 <_genuser_> altho, I play it like 6months nonstop and then drop it for 6mo doing hardcore coding, moving watching, etc. etc. Apr 25 03:52:50 <_genuser_> g00s: oh yeah, getting that rectifier sound or something on a solid state amp crank all teh way up to..... 1 doesn't cut it Apr 25 03:53:28 yeah i had a boogie single rectifier Apr 25 03:53:38 <_genuser_> I've really liked most of the signal processors, amp simulators, all in one units. digitech RP series, or the boss ones. Apr 25 03:54:15 <_genuser_> so I might drop 500 on some floor unit and just use that for recordings too. :) that is if I ever try to record more hardrock, etc. Apr 25 03:56:21 So then no for non root Apr 25 03:56:46 _genuser_ i'd probably wind up getting some line6 these days heh Apr 25 03:57:09 <_genuser_> g00s: yeah, I like those. small compact, combo amp, just sit there and jam out. Apr 25 03:57:42 <_genuser_> I did look into getting a 1W (maybe 5W) tube amp head and letting it really warm up and crank it to 10. And then line-out it to mixing console. Apr 25 04:00:01 I've been doing android apps for a few years now but never UI work. Now I need to do UI work :) I know how everything works but I am just ot familiar with what the best practices are Apr 25 04:00:13 I'd imagine it being something like css where you describe the layout in layout xml files Apr 25 04:00:18 then use styles to style them Apr 25 04:00:25 but I haven't seen apps take this approach Apr 25 04:00:55 <_genuser_> most app use this approach. some devs actually generate a view programmatically. Apr 25 04:00:55 anyone know of a really good sample app Apr 25 04:01:07 is it better to generate it programatically? Apr 25 04:01:25 just worried my first attempt at UI is going to look like a novice Apr 25 04:01:27 i'd rather work on content provider than UI stuff :D Apr 25 04:01:34 <_genuser_> keeping your layout in xml has one immediate advantage and that is that you can see the layout in design view before running it. Apr 25 04:01:39 g00s: yeah that's what I've been doing Apr 25 04:01:49 g00s: a lot of component, system type work Apr 25 04:02:21 in the sample apps, I see a lot of people use hardcoded integer values for margins/padding, etc. but I thought this was bad practice Apr 25 04:04:08 sleepster yeah do as much in xml as you can Apr 25 04:04:58 sleepster also read http://blog.danlew.net/2014/11/19/styles-on-android/ Apr 25 04:05:17 one question I had is that I notice in layouts, people use RelativeLayout, LinearLayout, etc. but then occasionally, there is a custom packagename someone puts in there like "com.something.SomeView" Apr 25 04:05:35 if that is the case, then that mean the packagename for LinearLayout, RelativelyLayout, etc. must be implicity Apr 25 04:05:37 implicit Apr 25 04:06:06 ex. https://github.com/emdete/tabulae/blob/master/src/main/res/layout/downloaderactivity.xml Apr 25 04:06:23 there is a project that specifies a custom view Apr 25 04:06:43 org.pyneo.maps.view.MapView is a custom class Apr 25 04:06:58 correct, that probably extends View Apr 25 04:06:59 custom view Apr 25 04:07:04 yeah Apr 25 04:07:25 <_genuser_> so needless to say neither of you have worked with gridview much then... Apr 25 04:07:48 no , sorry I haven't Apr 25 04:11:33 why did I wait so long to start using picasso, this is amazing Apr 25 04:12:03 <_genuser_> lol dingleberry Apr 25 04:12:47 hello Apr 25 04:13:16 is there some way to change the remote URL of a github repo tied to a project in android studio? Apr 25 04:14:42 hephaestus_rg: i would hope .git/config, but that's a guess Apr 25 04:15:26 yeah if it was a normal thing, i'd just do it from the CLI Apr 25 04:15:37 but i'm not sure what kind of magic android studio has Apr 25 04:15:42 that would break if i did that Apr 25 04:25:50 ok i guess doing it in the CLI didn't break anything Apr 25 04:25:52 :D Apr 25 04:31:24 anyone have suggestions for a lightweight parser library (lighter weight than antlr) .. that will work on android, something allong the lines of parboiled Apr 25 04:33:39 :'( Apr 25 04:34:10 g00s: Why not just generate it with antlr and include that source in your app? Apr 25 04:34:29 CedricBeust still requires tha antlr runtime though right ? Apr 25 04:34:34 g00s: intellij has one, but it's geared towards language plugins for IDEA. I'm not sure how general purpose the parser it produces is Apr 25 04:34:59 i think antlr depends on stringtemplate too , so both would be required Apr 25 04:35:03 https://github.com/JetBrains/Grammar-Kit Apr 25 04:35:21 JesusFreke cool thanks Apr 25 04:36:37 i loved terrance par's antlr books, those were great Apr 25 04:36:48 I'm not positive, but I don't think the string template library is required for an antlr generated parser. It's just required to generate the parser to begin with. Apr 25 04:39:13 Or rather, I don't think it's required unless you use specific features (in antlr 3. not familiar with antlr 4) Apr 25 04:40:14 The antlr-runtime jar is ~150kb, and ~100 classes Apr 25 04:40:20 dunno what the additional method count might be though :) Apr 25 04:40:42 yeah, i'm not familiar with 4 either. seems it just depends on org.abego.treelayout Apr 25 04:41:00 i thought that it had a tendancy to blow up dvm's stack in lookahead Apr 25 04:42:50 lol antlr4-runtime uses swing Apr 25 04:43:13 hahah, wth? Apr 25 04:44:12 maybe that can be fixed with some proguard-fu Apr 25 04:50:35 while (! (socket == null || socket.isClosed()) && (line = socketReader.readLine()) != null) <--- SocketException: Socket closed !? Apr 25 04:53:19 JesusFreke https://code.google.com/p/treelayout/ Apr 25 04:55:00 g00s: ah, is that what depends on swing? Apr 25 04:55:06 well i guess i could use this port https://github.com/bkiers/antlr4android Apr 25 04:55:27 it depends on that , but also has some swing stuff internally Apr 25 04:55:46 damn it, that just seems so busted Apr 25 04:56:24 i guess a proper port would s/swing/androidwidgets Apr 25 04:57:26 <_genuser_> all this for a parser? Apr 25 04:57:33 A proper port wouldn't include any dependency on a graphical library for a parser Apr 25 04:58:00 i think the tree view might be there for diagnostics, like to visualize the AST Apr 25 04:58:13 i suppose that could be useful, but ugh! Apr 25 04:58:20 Sure, put it in a separate package Apr 25 04:58:24 I mean maven package Apr 25 04:58:43 <_genuser_> no maven? android is all about gradle now... !! Apr 25 04:58:54 Still using maven packages Apr 25 04:59:26 i have to check again whether the LL(k) algorithm he uses is android friendly; it definitely doesn't have mechanical sympathy :) Apr 25 04:59:44 Is your language LL? Apr 25 05:00:55 i'm using ragel atm which is for regular languages; its good. i was thinking about making a DSL, and in that case i would just want one parser for both duties i think - not sure i haven't made the DSL yet Apr 25 05:01:39 i would do my best to eliminate ambiguities Apr 25 05:01:57 Your app will accept users typing sources in that language Apr 25 05:02:06 its been a long time since i used lex / yacc :) Apr 25 05:02:27 CedricBeust oh, its a DSL that i would include for congiguration Apr 25 05:02:31 lol Apr 25 05:02:40 <_genuser_> man, I'm just getting stuck on this gridview multiselect thing. Apr 25 05:03:08 <_genuser_> I should just code is myself, there's even examples online. but I'm still trying to see if it can be done on it out of the box. Apr 25 05:03:28 _genuser_ good thing you aren't using recyclerview :) Apr 25 05:03:38 CedricBeust have you used any parser generators lately ? Apr 25 05:03:43 i also wonder about xtext Apr 25 05:04:08 <_genuser_> g00s: why is that? Apr 25 05:04:15 see, the eclipse ecosystem has some damn nice things Apr 25 05:04:39 _genuser_ RV is tons more boilerplate, multiselect is not there, you have to do it from scratch Apr 25 05:05:38 <_genuser_> g00s: I see. I saw some sample code for it on vogella, and that guy does pretty complete tuts. Apr 25 05:05:52 <_genuser_> and you still have to do multiselect yourself on gridview, I think. so far that's my research. Apr 25 05:05:59 <_genuser_> wonder why taht wasn't provide out of the box. Apr 25 05:47:59 Is there a Maven for android? (Like for programing in aide) Apr 25 05:51:16 Why AIDE? Apr 25 05:52:19 wtf is a maven for android Apr 25 05:52:31 Someone who knows Android very well? Apr 25 05:54:19 and who use aide seriously Apr 25 06:00:37 Tactical i program with aide on my droid Apr 25 06:01:14 Why? Apr 25 06:03:31 dragorn dang its getting cold :D Apr 25 06:06:46 I am with out a computer at moment Apr 25 06:12:12 CedricBeust http://chadaustin.me/2015/04/the-long-term-problem-with-dynamically-typed-languages/ Apr 25 06:12:37 g00s: yeah I read that, agree with it Apr 25 06:14:03 I am missing something blindingly stupid, and I am not sure what it is. I loaded a new image resource and replaced ic_launcer.png with my logo. When I run the app, it does not use that logo, it uses the default android one. Apr 25 06:14:40 ic_launcer.png, eh ? Apr 25 06:14:53 *launcher Apr 25 06:15:13 android:icon="@mipmap/ic_launcher" and it's spelled right in the folder Apr 25 06:15:22 Android Studio just replaced the one that was already there Apr 25 06:17:14 Do you have an image for each density? hdpi, mdpi, xhdpi? Apr 25 06:17:25 yes Apr 25 06:17:30 Studio took care of that Apr 25 06:21:31 hmm, how did you add the image? Just pasted it in the right folder? file -> new -> image asset? Apr 25 06:21:50 file -> new -> image asset Apr 25 06:22:08 -> launcher icons Apr 25 06:22:39 hi Apr 25 06:22:57 how can I still perform bluetooth scanning and networking operation when phone is asleep ? Apr 25 06:23:05 I noticed it stops everything Apr 25 06:23:17 have you verified the images are correct by opening them in studio? Apr 25 06:23:31 zko: yes Apr 25 06:24:05 as well as viewing them on the file structure for the project, I have had studio clean the project, and checked studio's build folders Apr 25 06:24:12 the images are correct everywhere Apr 25 06:24:25 I have even tried changing to a different image just to verify it isn't the image Apr 25 06:24:41 I'm missing something simple, I know I am Apr 25 06:25:30 yeah it's most likely something simple. The same thing happened to me once, I just don't remember exactly what I did to fix it Apr 25 06:26:10 hmm, I am going to generate the signed apk and see if it does it as well Apr 25 06:26:23 have you tried restarting studio? Apr 25 06:26:47 Initially, not since swapping out the resource several more times Apr 25 06:27:52 wth, the signed apk works Apr 25 06:27:59 interesting Apr 25 06:28:19 well, partially Apr 25 06:28:24 partially? Apr 25 06:29:17 it showed the correct icon on the installer, but not on the home screen or app drawer Apr 25 06:29:32 where as before, it wasn't even showing the right icon on the uninstaller Apr 25 06:30:12 shows wrong icon when I uninstall Apr 25 06:30:19 but right icon when I install Apr 25 06:30:28 hmm, wonder if my phone is doing it Apr 25 06:31:05 try uninstalling the app and restarting your device, then see what happens Apr 25 06:34:35 zko: that did it Apr 25 06:34:37 odd Apr 25 06:38:28 that is odd Apr 25 06:41:55 I blame nova launcher Apr 25 06:45:27 g00s, the dynamic. vs static argument seems pretty obvious to me Apr 25 06:45:42 use dynamic languages for crap that will get thrown away Apr 25 06:45:59 bah even that I don't see the point Apr 25 06:46:26 well, can't beat a couple seconds throwing into a script and running it Apr 25 06:46:53 the article gave me a perspective i never thought of though; if people aren't diligent with test upkeep, and coverage falls it becomes difficult to know whether you can even refactor something safely Apr 25 06:47:21 i guess that is true for any type system, but ... Apr 25 06:47:37 g00s: It's worse than that, I wrote about it almost ten years ago: http://beust.com/weblog/2006/10/01/dynamic-language-refactoring-ide-pick-one/ Apr 25 06:48:31 yeah, i probably read that at some point , looks familiar :) Apr 25 06:48:34 test upkeep is a joke Apr 25 06:48:50 look at any large scripted system, the tests are practically non existent Apr 25 06:49:03 any system, not just scriptes Apr 25 06:53:04 the compiler takes away some of the test burden Apr 25 07:12:53 "Median Age At Google Is 29, Says Age Discrimination Lawsuit" , interesting Apr 25 07:19:11 Sounds about right Apr 25 07:19:23 Still a bit baffled by this kind of lawsuit, though Apr 25 07:20:41 errr.... how are you suing over age discrimination when the younger people really are the more talented for the work google is doing? Apr 25 07:21:34 I'm 30, and I know that there are loads of people more talented than I am that are younger than me. That's because they got started on all this at a younger age Apr 25 07:21:45 danl: That is an open question, I was just pointing out that old/young people are not a protected section so companies should be free to hire in any range that fits their business better Apr 25 07:22:13 My question was a bit rhetorical Apr 25 07:35:18 If I use minSDK = 19 do I still need to use the appcompat library? Apr 25 08:26:54 Hello! How can I run unit tests both on the development machine (which I run with "gradle test") AND on the emulator (which I run with "gradle connectedCheck") ? Apr 25 08:43:57 <_genuser_> great thing about AS? It actually respects the F3 on windows... Apr 25 08:44:04 <_genuser_> good people. Apr 25 08:46:47 developing on windows? meh Apr 25 08:52:34 <_genuser_> yep, using windows for all desktops. Apr 25 08:52:54 <_genuser_> odd, AS is running my app and compiling it but not showing _anything_ in logcat. Apr 25 08:53:42 How does proguard interact with final static strings? Apr 25 08:56:12 <_genuser_> nice using picasso with a custom handler is still going out of memory. I have to re-write custom handler logic. :) Apr 25 08:56:48 Are there any easy ways to get Maven gradles onto android devices? Apr 25 09:13:21 ronkrt: what? Apr 25 09:14:17 I'm trying to get Maven reps locally on my android but Maven Downloader is not work Apr 25 09:14:21 Working* Apr 25 09:15:19 And you want to do this in gradle? Apr 25 09:16:04 Lemme show you my options Apr 25 09:17:23 http://imgur.com/QuTvDLa Apr 25 09:17:41 If you're using gradle, you should be able to add your local repository see the userguide section 8.5 (http://gradle.org/docs/current/userguide/artifact_dependencies_tutorial.html) Apr 25 09:18:33 I'm trying to get org.apache.maven.plugin Apr 25 09:19:04 Well, that app I've never seen before, and I have no idea what it is for :) Apr 25 09:19:09 I'm using a third party app Apr 25 09:19:15 Dismissive Apr 25 09:19:24 Downloading Apr 25 09:20:56 Description Apr 25 09:20:56 The Maven Dependency Downloader creates a local Maven repository on your tablet or smartphone. Apr 25 09:22:34 And I don't quite understand why you would want to do that. But have you tried contacting the people who made the app? Apr 25 09:24:27 I want to make the repos local because aide doesn't use remote repos Apr 25 09:24:46 I cant get a hold of them Apr 25 09:27:14 Hello Apr 25 09:27:37 I've read that android has libc in itself Apr 25 09:27:51 What's the difference b/w libc. glibc and gcc? Apr 25 09:34:43 Got it Apr 25 09:37:41 can someone help me with http://stackoverflow.com/questions/29863368/android-studio-1-1-0-setting-minifyenabled-true-causing-issues-with-app Apr 25 09:53:38 Hello Apr 25 09:53:59 Is there a possible way to stop other apps from my apps? Apr 25 09:54:25 Because I start a other app with startActivity from my app but I need to close it later... Apr 25 09:56:59 think of it in another way Apr 25 09:57:10 would you accept if another app closes your app? Apr 25 10:15:10 Hey not sure why my button click is not registering here http://stackoverflow.com/questions/29863869/cannot-get-onclickbutton-in-custom-adapter-to-respond-correctly Apr 25 10:18:48 Odaym yes, I know. But I need it... "am force-stop package" works but I can't execute it from my app or? Apr 25 10:19:10 you shouldn't be allowed to do this Apr 25 10:19:56 I don't know what you're looking for, I haven't googled, but this shouldn't be allowed to happen regardless whether you need it or don't Apr 25 10:20:15 But how can Task Killer apps kill the app? Apr 25 10:20:31 that's its job, it advertises clearly what it wants to do Apr 25 10:20:37 Lonesoldier728 setOnItemClickListener on the listview instead of onItemClick in the adapter Apr 25 10:21:18 hmm nm i reread Apr 25 10:21:25 Odaym Okay, but then I can add it also to me app or? Apr 25 10:21:41 dont know bro, but its highly dangerous to do something stealthy like that Apr 25 10:21:45 aaearon nevermind you said? Apr 25 10:21:47 you might get booted from the store fo eva! Apr 25 10:22:07 It's a private app.. So that's not the problem Apr 25 10:22:29 then why you asking man Apr 25 10:22:45 seem to know all what you need, go do it Apr 25 10:23:24 how would I select the button from the listview on selectitemlistener then Apr 25 10:23:31 <_genuser_> man, I have too many packges in my app. over organization, perhaps. Apr 25 10:23:53 Odaym But I don't know how TaskKiller apps do it... I will watch into some codes.. Apr 25 10:24:00 some codes Apr 25 10:24:01 :P Apr 25 10:24:22 get some bag of codes and throw it on the ground and start to search Apr 25 10:30:52 Maybe in Lollipop was changed something that they methods in the internet not working anymore... Apr 25 10:34:34 http://stackoverflow.com/questions/29863869/cannot-get-onclickbutton-in-custom-adapter-to-respond-correctly?noredirect=1#29863957 Does anyone understand how I write the code for the answer written here Apr 25 10:36:48 nevermind explained Apr 25 10:48:27 I am trying zxing-android/qr-encoder and I got a bitmap made from X and empty spaces, is there any online tool to convert it to PNG to try it? Apr 25 10:49:30 http://paste.ofcode.org/fQhUxGMrn35PFdEv5xfqLV here is the QR Apr 25 10:59:12 someone here who can bit about zigbee? I will build a zigbee gateway/router for testing someone who is has experience? Apr 25 12:19:11 Is it possible to run mvn clean package via terminal on android? Apr 25 12:58:55 hey guys? Apr 25 12:59:19 do you download a lot of apps of whatever function, just to get an idea of what's going on out there as far as UI trends, performance differences, etc..? Apr 25 13:00:47 Odaym there are a few free ui design programs in play store.. A good one is aide ui dev but it's $2.99 Apr 25 13:01:04 that isn't what I meant Apr 25 13:02:50 most of the times, no Odaym. But looking at competitors products make sense Apr 25 13:03:16 do you expose yourself to a lot of famous apps say from Editor's Choice apps, just to see how the "pro's" are doing things? Apr 25 13:03:20 that's more like what I meant ronkrt Apr 25 13:03:36 I did for my audio dsp synth drum machine whatever app Apr 25 13:03:50 make sense to compare to the "top" apps Apr 25 13:04:24 yes Apr 25 13:04:39 I also did it for some watchface related to android wear development Apr 25 13:06:20 Does the android os 4.4.2 have the JDK on it out of the door? Apr 25 13:06:44 no ronkrt Apr 25 13:07:11 Ok time to install Apr 25 13:07:35 I meant, there is no jdk provided with android os Apr 25 13:07:44 not sure is out of the box != out of the door Apr 25 13:07:55 out of the door :P Apr 25 13:07:56 lol Apr 25 13:08:20 I'm visualizing "out of the door" :D Apr 25 13:08:30 could be in the wall Apr 25 13:08:53 out of the door could mean like "when it ships" Apr 25 13:08:57 but still, not a valid expression Apr 25 13:08:59 downvoted Apr 25 13:11:35 Lol this is going to be epic Apr 25 13:56:46 Is there any way to get this specific of a name from the device using your app? https://i.imgur.com/cWfBIoS.png Apr 25 13:56:55 Like the Google Play Store does. Apr 25 14:11:54 list.contains(object) ... does object have to be exact on every single value Apr 25 14:12:07 or is there a way to say if the userIds match Apr 25 14:14:26 Lonesoldier728: it uses equals Apr 25 14:14:58 is there a way to check if the userids match then without looping through the list? Apr 25 14:15:11 or contains basically does that anyways so I might as well loop it Apr 25 14:15:23 you not saying what your objects arer Apr 25 14:16:08 contains loops through the list and check every element with equals() Apr 25 14:17:08 perhaps override your equals in the user object so it would check just the user id if that makes sense for you Apr 25 14:20:28 or instead you can use a hashmap maybe Apr 25 14:20:32 O(1) to pick Apr 25 14:26:25 adq: that is for get not for contains though IIRC Apr 25 14:26:40 or maybe he should use HashSet Apr 25 14:26:59 IDK, he didn't mention much details :) Apr 25 14:27:16 not sure, testing if it contains can be reduced to getting it Apr 25 14:27:29 but indeed, lack of details Apr 25 14:28:19 Hello, I'm using xamarin, what's the best way to pass variables data between layouts? Apr 25 14:33:24 What's the most modular way of doing a color chooser? I am trying with RadioGroup but there's no way to easily tint radio buttons... (something like this: http://www.clubpenguininsiders.com/wp-content/uploads/2011/06/cp-sign-up-step-1.jpg) Apr 25 14:33:47 how to apply Material design in kitkat ? Apr 25 14:37:10 indeed Apr 25 14:37:30 check https://github.com/gabrielemariotti/colorpickercollection dimitrovskif Apr 25 14:38:09 adq: Cool, I'd like the same but with a View instead of Dialog Apr 25 14:38:25 should be relatively easy Apr 25 14:38:35 maybe? Apr 25 14:40:33 Hello Apr 25 14:40:49 I should adding a widget to an app Apr 25 14:41:54 question: application can be launched by widget either drawer Apr 25 14:42:32 have I to use only app widget class in the main code? Apr 25 14:44:04 for example: http://www.tutorialspoint.com/android/android_widgets.htm Apr 25 14:44:11 appwidgetprovider Apr 25 14:48:01 hey icedp adq sorry had to step out for a moment but yeah basically I am letting a person add friends to a list but if the friend exists I do not want duplicates Apr 25 14:48:34 What changes have I to add launching application by widget and by icon in drawer? Apr 25 14:50:01 so the list contains people from before hand so now I just want to confirm that the person does not exist before inviting them, so I was gong to do a for(User eachUser: userLists) loop unless contains works... but from what the list contains to what the actual user item, there will be different fields but the userId field will be the same so I wanted to base it off that if they are equal on the userId field then not to incl Apr 25 14:50:01 ude the person Apr 25 14:50:10 how to apply Material design in kitkat ? Apr 25 14:50:31 rohit7roy what you trying to do exactly Apr 25 14:50:47 add a drawer? Apr 25 14:51:03 im trying to implement material design in my existing app Apr 25 14:51:54 and i want to runthat in my kitkat device Apr 25 14:54:13 https://developer.android.com/design/material/index.html Apr 25 14:54:20 Well look at that Apr 25 14:55:39 i've gone through tht Apr 25 14:55:58 Lonesoldier728: HashSet with userids or HashMap Apr 25 14:56:53 is that better than just looping through icedp Apr 25 14:57:11 Lonesoldier728: i've gone through tht Apr 25 14:57:33 Yeah sorry, rohit7roy I have yet to really implement it outside of the navigation drawer Apr 25 14:58:09 Lonesoldier728: practically won't matter in this case, but generally faster. Just use what makes sence, HashMap/Set will give you automatically guarantee of no duplicates Apr 25 14:58:52 can you show me an example Apr 25 14:59:00 well if you hashCode() works right, that is Apr 25 14:59:30 Lonesoldier728: ok no problem :) Apr 25 15:00:52 Lonesoldier728: HashMap users = new HashMap; users.put(user.getId(), user); users.containsKey(user.getId); Apr 25 15:00:57 I get :"Error CS0121: The call is ambiguous between the following methods or properties: 'Android.App.AlertDialog.Builder.SetMessage(int)' and 'Android.App.AlertDialog.Builder.SetMessage(string)' (CS0121) (webservicetest1)" when passing a JSON index data to setmessage Apr 25 15:01:21 Lonesoldier728: forgot the () but the gist Apr 25 15:02:12 yeah kk but that is more efficient? then for(User user: usersList) { if(user.getId().equals(other.getId) { return true}} Apr 25 15:02:17 than* Apr 25 15:02:35 could anyone help? Apr 25 15:04:29 Lonesoldier728: yes it's O(1) vs O(n) Apr 25 15:05:31 livtyler: Sounds like you need to tell it whether you're passing it an int or a String Apr 25 15:06:53 SimonVT: thank you, how to do it? I'm sending this: JsonValue json = await getnombreWS (url); AlertDialog.Builder alerta = new AlertDialog.Builder (this); alerta.SetMessage(json["nombre"]); Apr 25 15:08:42 icedp, foreach is O(n) and equals is O(1), right? Apr 25 15:09:06 livtyler: Find out how you get a String from json["nombre"].. I don't know what json library you use Apr 25 15:09:55 do you guys use android studio? or would intellij idea be good for android dev? Apr 25 15:10:02 SimonVT: using System.Json; Apr 25 15:10:41 http://pastebin.com/8qDv4F4L Apr 25 15:10:54 so the top one is more efficient than the bottom one? Apr 25 15:10:56 I have no idea what System.Java is Apr 25 15:11:02 Json Apr 25 15:11:56 adq: Managed to do it without a Dialog, had to edit their code though Apr 25 15:12:12 Hey guys.. How can i start adb in terminal emulator on my android with a unique id and start the server? Apr 25 15:12:13 adq: Thanks man, saved me! (I have a very small deadline.....) Apr 25 15:12:21 :) Apr 25 15:13:38 Lonesoldier728, are you populating the hashmap in the top one? but only checking to see if there is a match in the bottom? Apr 25 15:14:08 actually the top one populates hashmap, and then checks to see if there's a match. but bottom only checks to see if there is a match? Apr 25 15:14:09 Lonesoldier728, http://bigocheatsheet.com/ Apr 25 15:14:13 profile your code anyway Apr 25 15:14:15 yeah basically the top one is a setup once then the only calls made on Apr 25 15:14:29 each getview is the loop vs the containsKey Apr 25 15:15:11 wagonboi: yes, O(n) is the worst case. if you element is in the beginning of the array than it's O(1) =) Apr 25 15:15:46 ah i see. i would use the top one myself. cause yeah, the bottom iterates thru the entire hashmap looking for a match. while the top one just uses hashmaps O(1) lookup to see if there is a match Apr 25 15:17:37 (fyi iterator is slower than a simple for loop with an int as index and also create some allocations) Apr 25 15:17:56 I see often iterator is faster blablabla, it's not lol Apr 25 15:19:42 how does one iterate through hashmap with an index if there may be empty entries? Apr 25 15:20:28 you get the keys? Apr 25 15:20:34 Lonesoldier728: you must break from the loop in second case. in the first case you must store you data in HashMap. If you were to create it each time to look up - it won't be more efficient in any sense Apr 25 15:20:34 you don't iterate hashmap Apr 25 15:20:59 you might iterate the key of the hashmap but then this starts raising the : why hashmap? Apr 25 15:21:16 ah i see Apr 25 15:21:21 confused lol Apr 25 15:21:40 so yeah the hashmap is only created once and then iterate the key i guess Apr 25 15:21:48 as oppose to the loop Apr 25 15:21:51 icedp, i think his second loop implies that the hashmap was alrady created Apr 25 15:21:53 on the second which happens Apr 25 15:22:04 the second loop has no hashmap the list is already there Apr 25 15:22:05 document yourself more on it :) Apr 25 15:22:26 few answers on irc will not document sufficiently all these stuff Apr 25 15:22:31 Lonesoldier728, in either case, the hashmap is already created, right? the question is whether to use equals or containsKey to find a match Apr 25 15:23:04 http://developer.android.com/reference/java/util/HashMap.html check the overview Apr 25 15:23:09 adq: RE: fpr each loop. not always for (int i =0 ; i < 5; i++) { Apr 25 15:23:12 break; Apr 25 15:23:14 } Apr 25 15:23:20 adq: oops sorry. wait a sec Apr 25 15:24:01 adq: http://stackoverflow.com/a/256861/1056386 regarding for vs for each Apr 25 15:24:47 ok let me specify the list is being passed in no matter what, now for each view i can loop through the list and look for if the views id matches the list id before moving on to the next vew or... one time create a hashmap with the userid being the key, then on each view check the hashmap if it contains the key that matches the userid before moving on to the next view and doing the same thing Apr 25 15:24:50 i will, check https://www.youtube.com/watch?v=MZOf3pOAM6A&feature=youtu.be icedp Apr 25 15:24:57 i'm glad "Colt" pointed out it Apr 25 15:25:42 as it computes the limit of the array index only once. << Apr 25 15:26:00 this is why you always compute the length one time above the "for (int i = ...; Apr 25 15:26:06 even in a classic loop Apr 25 15:26:15 to avoid having the length being recomputed at each cycle Apr 25 15:27:00 but i see the point, for ppl using (for int i = ... ; i < array.size() ; ..) but then it can be avoided by what i just said above Apr 25 15:27:17 computing the length above and putting a simple variable in the condition of the loop Apr 25 15:27:27 to avoid computing the size at each cycle Apr 25 15:28:23 Lonesoldier728, if you don't have thousand of view, you should not bother with performance Apr 25 15:28:40 what array sizes are you using adq ? they must be pretty large to warrant your approach? Apr 25 15:28:55 exactly Apr 25 15:29:18 in class i've only worked with arrays <1000 i think. wondering what typical arrays sizes in the field are Apr 25 15:29:33 it'sn ot only dependent on the array sizes itself, but how many times you will do it per second too Apr 25 15:29:41 (think of a game loop, or real-time audio processing) Apr 25 15:30:17 yeah im thinking maximum it will be 100-200 users in a list Apr 25 15:30:21 so imagine your arrays < 1000, but i need to process them many times per second Apr 25 15:30:27 times per second? i thought loops only did it once? or is for concurrent applications? Apr 25 15:30:33 it's the same as if they were longer but i need to process them less time Apr 25 15:30:37 * once per iteration Apr 25 15:31:05 modulo any optimization Apr 25 15:31:06 :p Apr 25 15:31:21 so essentially doing it with the hashmap.containsKey vs for(User user: userList ... there is a difference still ? Apr 25 15:31:59 there is, but it might be insignificant if you only have few users and do that once Apr 25 15:32:22 yes Lonesoldier728 . just think like this: containsKey returns an answer right away. but user:UsersList needs to take each user and compare it Apr 25 15:33:20 adq: wow well, so Effective Java had a mistake then Apr 25 15:33:51
