**** BEGIN LOGGING AT Wed Aug 28 02:59:58 2013 Aug 28 03:17:43 How to rebuild "vboxdrv"? My virtual machine cannot start. # modprobe vboxdrv --> FATAL: Module vboxdrv not found. Aug 28 03:18:03 The virtualbox-dkms is already installed. Aug 28 03:18:45 Ooops, wrong channel, sorry... Aug 28 03:22:45 hello guys, does anyone know where Android Studio stores it's preferences? Everytime I quit the app and restart I lose preference settings Aug 28 03:24:53 hmm, how shitty is the ui if I startActivity() from a ContentProvider's query() ? Aug 28 03:26:44 hey all. when building modules with "mm", how can i not strip the debugging symbols? Aug 28 03:35:30 pfn: check this http://www.doubleencore.com/2013/06/context/ Aug 28 03:35:45 scroll down to the table, if cant be bothered reading it Aug 28 03:35:53 actually, not a problem for my use-case Aug 28 03:36:01 my activity is the one calling the content provider Aug 28 03:36:09 so it can just do shit if the content provider returns null, no big Aug 28 03:36:52 if you read the table, it states you can start an activity but it is a new task Aug 28 03:37:16 of course Aug 28 03:37:32 starting activity from background always requires a new task Aug 28 03:38:19 well its good you realise that :P Aug 28 03:38:51 I'm asking how shitty the ui is Aug 28 03:38:53 ux Aug 28 03:39:16 but re-thinking how I want to interface with the cp it's not a problem Aug 28 03:40:39 since the initialization from the cp doesn't have to happen internally for me, I just need to send it data if it returns null Aug 28 03:43:16 (to initialize with) Aug 28 03:58:25 is there a device that supports serial port comm access without rooting the device? tia Aug 28 04:00:03 Hey, I was hoping to find an Android developer to help us port our messaging program over to Android. We've already got a working version for PC Aug 28 04:04:14 Kristoff: See topic, no recruiting. Aug 28 04:04:36 hi Aug 28 04:04:37 Kristoff: it's just xml Aug 28 04:04:47 and java Aug 28 04:04:50 Oh? Sorry. Didn't notice that. So, no exceptions? At all? Aug 28 04:04:53 Also, I know its xml Aug 28 04:04:59 No exceptions. Aug 28 04:05:00 but its the outdated libraries that's the problem Aug 28 04:05:07 Specifically the encryption libraries Aug 28 04:05:21 They're using SUN libraries. Not Oracle, which have different standards Aug 28 04:06:00 If I was going to recruit, I'd throw it up on hackernews Aug 28 04:06:07 Hmm. Then, Nilium. Within the rules, how could I find someone to work WITH us? Aug 28 04:06:22 By going somewhere that's for recruiting. Aug 28 04:06:46 seitensei mentioned HN, aka startup fanfiction central, then there's also stuff like the various careers sites out there. Aug 28 04:07:00 You see, I've tried that. And I've found incompitant 12 year olds that think they know how to write Java code. But okay, sorry about that Aug 28 04:07:16 I'm not trying to be mean, just letting you know about the topic. Aug 28 04:07:53 I know you're not. And I know it's a grey area too. Kinda pushy, because technically, we're looking for help Aug 28 04:07:53 At any rate, you'll have to filter out the 12 year olds regardless of where you advertise. Aug 28 04:08:17 Yeah. Well, thanks anyways. Aug 28 04:08:18 just like we have to filter out 12 year olds who can't read the topic and spam this developer channel for their own purposes Aug 28 04:08:29 Or the ones who don't read documentation. Aug 28 04:08:31 I'm 18 >.> Aug 28 04:08:44 Recruiting isn't inherently harmful, but if the channel permitted recruiting, there would be more recruitment going on than productive discussion Aug 28 04:08:47 I just didn't notice the thing up there. It's late, and I'm not used to IRC Aug 28 04:08:49 then act like an adult and follow the rules Aug 28 04:08:52 Oh how I wish to throttle the living hell out of people who don't read docs. Aug 28 04:09:10 Nilium: I like to point and laugh, but I've found that people don't like that. Aug 28 04:09:19 Kevin, act like an adult and be mature. Realize that the FIRST irc channel that I join may not be something I'm familiar with Aug 28 04:09:42 Although, to be honest, the idea of recruiting via IRC seems rather odd to me. Aug 28 04:09:54 Especially if you're attempting to avoid 12 year olds. Aug 28 04:09:55 ...? Aug 28 04:09:57 * Nilium divorces himself of the recruiting conversation because it's already said and done. Aug 28 04:10:04 oh wrong highlight Aug 28 04:10:09 * kevin goes back in the shadows Aug 28 04:10:10 * seitensei gets back to coding Aug 28 04:10:21 Well, it's a group of dev's. I like the idea of finding someone who thinks they know what they're doing. And possibly just branch off into Skype and work together. Aug 28 04:10:27 It's not 4am yet, which means it's not bedtime. Aug 28 04:10:33 Heh. Aug 28 04:10:43 4am? That's an early night for me. Aug 28 04:11:13 Insomnia and obsession are the world's two most potent forces, right after gravity and coffee. Aug 28 04:11:15 I'm usually until 4-5am, unless I decide to wake at 4am. Aug 28 04:11:48 I can't focus during the day. Too many humans being disruptive. Aug 28 04:12:29 I can focus during the day, I'm just incapable of sleeping without being completely exhausted. Aug 28 04:13:38 I'm glad I don't have that problem. It would take me a good 3-4 days to get to sleep if that was the case. Aug 28 04:13:43 Plus now that I'm out of university, I kind of don't have anything to do 'til I can find a job somewhere around here. Aug 28 04:13:50 Same. Aug 28 04:14:05 Likely going to have to find something in retail -- Idaho's not exactly big on tech. Aug 28 04:14:07 The only programming work around here is ERP, sadly. Aug 28 04:14:32 PeopleSoft, SAP, and C#/ASP.NET, none of which are really exciting Aug 28 04:14:37 Ugh, PeopleSoft Aug 28 04:14:53 C#/ASP.NET, fair enough, but I wouldn't wish PeopleSoft/Code on anyone Aug 28 04:14:57 I've worked with PeopleSoft. Aug 28 04:14:58 D: Aug 28 04:15:03 I'm so sorry. Aug 28 04:15:09 I don't anymore. Aug 28 04:15:48 I did get a job offer from a healthcare company, but I did some research and it turns out their software is mostly Visual Basic 6. And they don't plan to change that. Aug 28 04:16:04 VB6 and MUMPS, specifically. Aug 28 04:16:05 An acquaintance of mine has been trying to convince me to develop mobile apps for PeopleSoft. Aug 28 04:16:18 I can see a market there, but do not want Aug 28 04:16:39 Tell this acquaintance to drop a bucket of angry spiders in their pants. Tell them they'll understand after that. Aug 28 04:16:59 MUMPS sounds like some kind of STD Aug 28 04:17:44 oh man, it was great. my last co, they had this huge pile of VB6 crap Aug 28 04:17:46 It's an old as hell sort-of-DB. Nothing wrong with it in and of itself, but VB6 and MUMPS combined basically means they're running old mainframes with layer upon layer of horrible VB6 stacked on top of it and don't know how to remove it Aug 28 04:18:22 hey is the samsung galaxy tab 3 a good development device? Aug 28 04:18:23 and the VB6 stuff was leaking memory, so the servers were always needing attanetion Aug 28 04:18:25 Mainframes are usually a good thing, but the layers of terrible code sitting on top of them now makes them look bad. Aug 28 04:18:40 but the business didn't want to rewrite the sw, but VB6 wasn't really supported Aug 28 04:20:21 DrSheep: That can be very subjective Aug 28 04:20:43 If it represents what you think is important target hardware, it's a good development device. Aug 28 04:20:57 I dislike old software- especially in an enterprise setting. Aug 28 04:21:16 seitensei why? Aug 28 04:21:18 I don't mind old software so much as badly written old software Aug 28 04:21:28 Which a lot of it is. Aug 28 04:21:57 Often it can be a pita to migrate data to newer systems Aug 28 04:22:51 DrSheep: It's very subjective; It has to do with your opinions and approaches as a developer. Aug 28 04:23:40 DrSheep: I personally think the Raspberry Pi is a great device to develop for, from a server/web perspective, in that, if your code runs well there, it'll run well mostly anywhere. Aug 28 04:23:52 lol Aug 28 04:23:57 gee thanks Aug 28 04:25:29 If you're looking at tablet development, might I suggest a device running Android 3.0 or 4.0? Aug 28 04:26:02 That'll do a lot to ensure that you can maximize the amount of users able to use your software. Aug 28 04:27:59 whatever you do, don't get a honeycomb tablet Aug 28 04:29:36 4.x only. Nobody that matters is using 3.x. Aug 28 04:31:07 Heh. Aug 28 04:31:33 if i have an app thats being designed for 1280 x 768 phone resolutions (s3, etc) can i use a tablet with a smaller resolution to develop with? im just looking for something relatively cheap so I dont have to buy a new phone Aug 28 04:32:07 DrSheep: Honestly, I don't think resolution really matters Aug 28 04:32:12 as far as numbers are Aug 28 04:32:27 i didnt think so either, but im being told weird shit Aug 28 04:33:06 I would stick to mdpi as the lowest that you support Aug 28 04:33:24 this feels like the last two days conversations all over again :S Aug 28 04:33:30 There aren't enough ldpi devices in use anymore to matter Aug 28 04:34:07 bankai_: You haven't had enough alcohol yet. Aug 28 04:34:24 it's 2:30pm :S i'll kill the days memories tonight, promise Aug 28 04:34:54 That being said, I've never enjoyed drunken programming. Aug 28 04:35:06 drunk, no, but have a few and it makes coding easier Aug 28 04:35:33 I lived in Tokyo last year, and some of the year before that, during university. Aug 28 04:36:08 drunken programming is a waste of time, and a waste of booze Aug 28 04:36:14 mmm ever had asahi strong off? good shit ... that makes for some good programming Aug 28 04:36:25 I'm not an Asahi fan Aug 28 04:36:29 I stick with Yebisu Aug 28 04:36:34 I will be getting on a plane to Osaka in... oh, 36 hours Aug 28 04:36:35 oh, you poor thing ... Aug 28 04:36:47 Good programming is implementing a recursive function to count the beers on the wall using your mouth. Aug 28 04:36:49 Leeds: have some takoyaki for me! I love osaka Aug 28 04:36:53 At least it isn't hoppy, bankai_ Aug 28 04:37:21 Hoppy is the most foul beverage I'd have the pleasure of drowning myself in. Aug 28 04:37:31 bankai_: not for me - I'm veggie-ish... never been to Osaka before, but did go to Kyoto last year... I'm looking forward to some okonomiyaki Aug 28 04:38:03 there's a great okonomiyaki place in ebisubashi ( really there's good food all around that area ) Aug 28 04:38:23 It's a shame that you'll be in Kansai. Kanto has the best monjayaki, and you usually have it after okonomiyaki. Aug 28 04:38:34 * Leeds makes a note... go to ebisubashi Aug 28 04:39:15 I've got a friend in Osaka right now, actually. Osaka is one of the nicer places to be if you're caucasian. Aug 28 04:39:52 hey- I'm getting a java.lang.VerifyError on an older Android version (that doesn't contain this class), but also does not call this class... How can I get around this? Thanks Aug 28 04:40:24 seitensei: we're sort of working our way around Japan - first trip just Tokyo, then Tokyo/Nagano/Kyoto, now Osaka/Kyoto Aug 28 04:40:39 shad0w1e: stack trace? Aug 28 04:41:22 also, Otsu for a Namie Amuro concert... Aug 28 04:41:26 My bud's teaching English over in Osaka. As a linguist, I should probably be doing the same, but I've pretty much been dashed on the rocks for not being caucasian. Aug 28 04:41:40 http://pastebin.com/sUUfWbtv Aug 28 04:42:35 seitensei: yeah, similar thing here in HK, generally held that caucasians do better as English teachers - at least if you're not a fully-qualified teacher in a regular school Aug 28 04:42:46 the issue is here-- notification = new Notification.Builder(serviceContext) , except this code should never be called on the lower SDK devices. Aug 28 04:43:31 shad0w1e: you don't have your manifest SDK stuff wrong? Aug 28 04:44:37 Ehh. this works fine on Android 2.3 even though this would only work as of Android 3.0 -where this class exists. Aug 28 04:44:43 But it crashes on Android 1.6 Aug 28 04:45:22 I've got to say, that's not something which would keep me up at night... Aug 28 04:45:29 I hear you Aug 28 04:45:38 But I'd prefer to not change the requirements of an existing app Aug 28 04:45:43 for that 0.1% of users on ancient devices Aug 28 04:46:13 more to the point - look at your install stats... does 1.6 even show up? Aug 28 04:46:19 about 1% Aug 28 04:46:52 0.85% Aug 28 04:47:35 Anyway what does this error mean? This code doesnt even execute.. Aug 28 04:47:54 I guess I'm a bit of a hypocrite - I've got 1.07% on *1.5* apparently! Aug 28 04:48:40 heh. yeah so anyway... Aug 28 04:49:22 Theres another way around this error which is to use the Android support library- but that will grow my app by 250% in size, so Id prefer to just not run this code on older Android. Aug 28 04:49:49 do you know whats going on? Aug 28 04:52:13 not really, sorry Aug 28 04:52:31 ok thanks. Maybe I can pick up an old version of the support library Aug 28 04:52:33 thats smaller Aug 28 04:55:29 AIUI, if you run proguard, it can strip out unused code/classes from your app Aug 28 05:01:27 Can anyone point me to an example of PopupMenu working with AdapterView? Aug 28 05:23:39 Leeds, it seems I can just pull .java files out of the support library instead of having to use the whole thing. Aug 28 05:34:30 Hi everyone. I'm trying to switch my site from using HttpClient to HttpURLConnection because I read that HttpClient has been deprecated. I am getting a fatal IllegalStateException from the new code though. It says the HttpURLConnection is "already connected". I have attached the try-catch segment of my connection function here (http://pastebin.com/TAMNMiYa). Any ideas? Aug 28 05:40:28 It's all cool to ask questions in here, right? Aug 28 05:43:17 BretHudson: that's what it's here for Aug 28 05:43:41 Leeds: Perfect, just know I asked something in another dev channel and everyone started freaking out. Aug 28 05:43:53 just don't ask dumb stuff :P Aug 28 05:44:07 I have a png in assets/textures and have no idea how to access the image and turn it into a bitmap. Aug 28 05:44:12 That too dumb? :P Aug 28 05:48:30 is there a reason you have it as an asset, not a drawable? Aug 28 05:49:23 Not really. Aug 28 05:49:34 I have it in both locations, actually. Aug 28 05:50:58 I haven't touched Android in about a year, so my knowledge is pretty rusky. Aug 28 05:55:26 for the most part, put stuff only in assets if you can't access it under res for the use-case you're in Aug 28 06:24:25 hmm, how can I protect my content further than just using permissions? those protections are so weak... Aug 28 06:24:33 s/content/contentprovider/ Aug 28 06:24:55 I could use a signature protectionLevel, but then it makes it so that 3rd party users need to be signed with my same key, and that's sucky Aug 28 06:29:36 I guess I can make calls to my content provider be blocking and require user interaction... Aug 28 06:45:19 hmm, given a uid/pid how do I determine package info? Aug 28 06:46:22 htop Aug 28 06:46:39 sry, laggy terminal Aug 28 06:46:52 pfn: PackageManager.getPackagesForUid Aug 28 06:47:59 kevinb, yeah, that's not quite sufficient, but I guess it's usable in conjunction with activity manager Aug 28 06:48:29 or uid is pretty much irrelevant, can find it out of activity manager based on pid Aug 28 06:49:15 that might require the running_tasks permission Aug 28 06:50:06 yeah, but simply getting packages for a uid doesn't tell you which package called Aug 28 06:50:13 (not for all instances) Aug 28 06:50:26 I suppose it's good enough for now Aug 28 06:50:57 yeah, but if you are checking for your own packages and don't used sharedUid then it basically does tell which called. but i agree it's not ideal Aug 28 06:51:25 not checking for my own packages Aug 28 06:51:41 oh, then indeed that makes it harder Aug 28 06:51:43 but I suppose I can store all the package info and if any of them change, I can force a new authz request Aug 28 06:52:11 * pfn is hacking on keepassdroid for shits and giggles Aug 28 06:52:16 I seriously want it to have a better ui, damnit Aug 28 06:52:26 ux Aug 28 06:53:03 I started android dev, but my ui looks shit. why :< Aug 28 06:53:05 so hax0ring in a contentprovider that has to do some modicum of authz Aug 28 06:53:15 neuro_sys, because ui takes effort to make look good Aug 28 06:53:26 what are some points to take Aug 28 06:54:20 if your ui looks poor, /and you don't know why/ its safe to go with the design guidelines ;) Aug 28 06:54:39 design guidelines are pretty tough for a noob to follow Aug 28 06:55:00 currently I'm still concerned about the framework in general than the ui Aug 28 06:55:09 I'll get to it soon Aug 28 06:55:56 so far the code tend to be awkward and messy Aug 28 06:56:21 like inner classes for every activity are full of asynctasks and custom adapters Aug 28 06:56:32 -inner Aug 28 06:56:38 I'm like dafuq Aug 28 06:56:44 hey there! Aug 28 06:57:00 neuro_sys, learn to structure your code better Aug 28 06:57:36 I just discovered the pencil gui tool, which seems excellent, but seems to neither have a documentation nor a help channel. Does anyone know how to add an "up" button to the action bar? Aug 28 06:57:45 android.content.pm.Signature is unique per-package, right? it's not just the public key, I hope Aug 28 07:01:22 how do you design your GUI? Paper? Special program? Directly in eclipse/android studio? other? Aug 28 07:04:40 http://stackoverflow.com/questions/18479473/tool-to-auto-generate-class-fields-of-view-type-from-layout-xml is any one familiar with a tool of this sort? Aug 28 07:05:10 RedNifre, I just imagine it and pull it out of my ass Aug 28 07:05:22 * pfn go to sleep Aug 28 07:08:41 pfn that works great, but I need something that I can use for user tests before I actually do any real work. Aug 28 07:09:18 But I guess you could just role play with your testes "so you are now using this awesome up. There's a mailbox there in the action bar and an up button to the west"... Aug 28 07:09:26 *testers Aug 28 07:09:50 *app not up. Uh, guess I'm awake too early... Aug 28 07:10:07 ahem Aug 28 07:12:26 afk, seeking coffee (but I'd still like to know how you design your GUIs. I used tiny paper notes, one per screen and I'm now looking at the Pencil GUI design tool) Aug 28 07:14:27 squared notebook and a pen Aug 28 07:14:36 a vit retro, but the easiest way Aug 28 07:14:41 Is it a bad idea to keep some bitmaps cached in memory? (If I'm using them in a listview)? Is it better to keep the byte[] or the Bitmap? Aug 28 07:15:07 keep the bitmap Aug 28 07:15:14 don't keep a drawable though Aug 28 07:16:04 why not a drawable? Aug 28 07:16:21 has a reference to context Aug 28 07:16:24 k Aug 28 07:16:27 another question Aug 28 07:16:43 sometimes Aug 28 07:16:48 I noticed something strange... Aug 28 07:17:01 I have one of those controls to slide left or right... I think it's a ViewPager... Aug 28 07:17:12 and I change the index... but it seems to be asynchornic... Aug 28 07:17:21 Like, it doesn't happen "immediatly" Aug 28 07:17:26 do you know something about that? Aug 28 07:18:09 at a guess, it'll wait for the next layout pass Aug 28 07:18:19 what's a layout pass? Aug 28 07:18:41 or draw, more likely Aug 28 07:18:51 the thing is, I'm doing an animation right after that thing Aug 28 07:18:56 and the animation ignores that change... Aug 28 07:19:05 yet if I stop the animation, the change works correctly... Aug 28 07:19:15 So my impression is that the animation starts before that changes get into effect Aug 28 07:19:28 (I'mchanging the slide before doing the animation ) Aug 28 07:19:47 try post(new Runnable(){do animation stuff}); Aug 28 07:20:02 alex_PP: thanks Aug 28 07:20:17 is there any other way to wait until the next animation cycle or thing? Aug 28 07:20:20 Hi Aug 28 07:20:37 viewtreeobserver's another way Aug 28 07:20:41 but more fuss Aug 28 07:21:02 another question... Aug 28 07:21:04 viewtreeobserver might be more robust Aug 28 07:21:08 i am starting an activity from a library (as startup) activity. during building/syncing with the device i get an ".apk not found" message in the console window, but everything works. should i be worried/change-something? Aug 28 07:21:13 is there any good way to do asynchronic I/O? Aug 28 07:21:36 I want to have one thread do multiple I/Os at the same time Aug 28 07:22:14 select() and poll() Aug 28 07:22:20 i think you want one thread per io task, if they're concurrent Aug 28 07:22:30 have a look at thread pool executor Aug 28 07:22:39 not sure if AIO is supported on Bionic, not to mention that AIO is broken on linux in general Aug 28 07:24:10 alex_PP: I'm downloading multiple images, and using one thread per image seems like a waste... Aug 28 07:24:26 alex_PP: I want async I/O... (at least if it works as it should) Aug 28 07:24:36 gavilan2: if it's socket i/o, use select() and poll() Aug 28 07:24:56 p_l: I don't want to write my own HTTP client.... Aug 28 07:25:15 gavilan2: you'll have to anyway if you want async i/o :P Aug 28 07:25:27 p_l: :/ that sux... Aug 28 07:25:27 i've always done that one at a time Aug 28 07:25:44 i'm not sure threading it would speed things up all that much Aug 28 07:25:45 Can I get async I/O from disk? or that it's also unavailable? Aug 28 07:25:46 also, you might want to instead pipeline the images in one socket Aug 28 07:26:00 (multiple TCP flows will fuck you up) Aug 28 07:27:53 p_l: I'm not sure that's a good idea in my case... The server is not all that deterministic.... Aug 28 07:28:00 gavilan2: async disk i/o theoretically possible, but usually ends up with threads involved, and on mobiles... well... Aug 28 07:28:01 ?!?!??? Aug 28 07:28:22 Gavilan3: you could make a service that returns the data you want as multipart stream Aug 28 07:28:31 multipart stream? Aug 28 07:28:34 yes Aug 28 07:28:51 basically, you are doing one continuous download, which includes several files inside Aug 28 07:29:04 packed as MIME stream Aug 28 07:29:14 shouldn't the keep connection open thing achieve the same effect? Aug 28 07:29:42 that is, file1file2 etc. Aug 28 07:29:50 Gavilan3: not exactly Aug 28 07:29:52 p_l: I don't know why, but we use a CDN, and the CDN from time to time has a really bad connection Aug 28 07:30:02 so you download 1 file in 1 sec, other file in 1 sec... then 1 file takes 20 seconds Aug 28 07:30:03 O?o Aug 28 07:30:05 Gavilan3: Mobile internet is bad connection, period Aug 28 07:30:06 it's strange... Aug 28 07:30:28 p_l: not really... because we played around, and we found that initiating 4 connections, only 1 of those get blocked Aug 28 07:30:36 and then we ask more files with the other 3... is strange Aug 28 07:30:36 Gavilan3: the behaviour regarding speed that you described fits exactly with ACK-dropping Aug 28 07:31:01 p_l: Great! how do I solve it? Aug 28 07:31:07 Gavilan3: can't Aug 28 07:31:15 p_l: That's not helpful :/ Aug 28 07:31:24 it's a problem at TCP-over-3GPP level, outside of your control Aug 28 07:31:41 you can do tricks to mitigate it, which the multiple streams *might* help sometimes Aug 28 07:31:42 p_l: who drops the ACK? the client? the server? Aug 28 07:31:46 Gavilan3: the network Aug 28 07:32:09 this causes window rescaling and backing off on the server side Aug 28 07:32:23 p_l: mmmm in the case we have, I don't think we get any data... Aug 28 07:32:33 p_l: eventally we get a connection time out Aug 28 07:32:38 Gavilan3: yep Aug 28 07:32:38 we retry, and we get it really fast Aug 28 07:32:56 the strange thing is that all the requests go to the same server Aug 28 07:33:05 http://teclo.net/ <--- if you want to get technical details, bug those guys or see if they have some reports public Aug 28 07:33:19 not really Aug 28 07:33:23 they are working professionally on the problem (I've met with them) Aug 28 07:33:28 I appreciate you giving me the name :) but that's enough.... Aug 28 07:34:24 Every time I learn more Java, it makes me think it's more and more a toy language :p Aug 28 07:34:35 Gavilan3: I think that as long as you're stuck with HTTP and CDN, multiple connections might be your only choice... but I'd recommend experimenting with how you manage them Aug 28 07:34:48 p_l: I will :) Aug 28 07:34:49 like "kill the connection early if it exhibits certain behaviour" etc. Aug 28 07:35:05 p_l: Hadn't had time yet... Aug 28 07:35:07 also, make sure to not overdo on amount of connections, that will... blow :) Aug 28 07:36:03 p_l: How many connections seems reasonable? Aug 28 07:36:24 Gavilan3: my guess would be go with 2-3, and experiment from that Aug 28 07:36:29 k Aug 28 07:36:34 thx Aug 28 07:36:39 hard numbers from repeated experiments are best :) Aug 28 07:38:30 What happens when you have an app that has navigation loops which can create an infinite stack of activities? Aug 28 07:38:45 change it Aug 28 07:39:01 My assumption was that this isn't a problem since the activities get stopped, only the intent remains, which is then used to restart that activity when the user goes back. Aug 28 07:39:17 the whole stack will be restored Aug 28 07:39:17 changing it is not an option since the customer is sure he is right. Aug 28 07:39:18 RedNifre: I think it's harder to cause than it seems Aug 28 07:39:29 but if not... Aug 28 07:39:37 well, at some point the device will barf, I guess Aug 28 07:39:56 try adding some points that will "cut" the chain? Aug 28 07:40:02 so the activities take their ram, all the time? Aug 28 07:40:42 I noticed that sometimes when I press back in an app that was runnig for days it seems like the previous activity takes a while to start and doesn't really have exactly the same state as before (e.g. is scrolled to the top instead of where I scrolled it to) Aug 28 07:41:07 RedNifre: activities can be GCed Aug 28 07:41:08 right. the previous ones may be killed Aug 28 07:41:36 So, infinite activity stacks are no problem because only their intent uses up memory, right? Aug 28 07:41:58 it's a terrible user experience Aug 28 07:42:02 you can never back out of the app Aug 28 07:42:58 You can. It's a catalog where an activity shows a product and a "more like this" section which starts activities to show the next product. Back leads to the previous product, up exits that catalog section entirely. Aug 28 07:43:46 well if you have "up" which does the right thing clearing the stack then that's perfect Aug 28 07:43:52 (if by "back out" you mean "exit somehow". It's not fun to use the actual back button for this, but that doesn't seem like a problem if the up button exits out of that part) Aug 28 07:44:28 yes, up goes back to the original pre-loop activity instead of putting a new one on the stack. Aug 28 07:45:13 yeah i think that's the best thing you can do. it's certainly in line with the design guidelines and makes logical sense Aug 28 07:45:15 Anyone here know any architecture guidelines regarding to advertising framework? I'm trying to find guidelines for ads framework with common methods to be able to provide ads from different publishers. As example the pnly thin I'm currently found is Microsoft.Advertising. Any ideas? Aug 28 07:46:53 BTW, is there an "end of support" date for actionbar sherlock? Maybe in the form of "When <4.0 drops to X%" or something like that? Aug 28 07:52:06 Hi, anyone know where can i find a noob tutorial for getting specific data from a url that contain json code ? (must contain a serch bar too) Thank you. Aug 28 07:53:07 google has that Aug 28 07:58:30 genymotion is pretty dang slick, although i'm fiddling with unloading my mac's bluetooth kexts to get that to work Aug 28 07:59:00 take up a bit more memory than qemu too :( Aug 28 08:01:55 does google play allow 3rd party app stores? Aug 28 08:02:16 play doesn't, android does Aug 28 08:03:05 that is, you can't distribute a client for a third-party store through the play store Aug 28 08:05:35 how difficult is it to remount the filesystem on a tablet so I can edit the hosts file? Aug 28 08:06:01 atm the tablet is not rooted so the filesystem is readonly Aug 28 08:06:13 hm, i hope easy. i think everybody should be able to modify that with little hassle Aug 28 08:06:35 doesnt look like it. Aug 28 08:06:44 I think I need to remount the filesystem.. :( Aug 28 08:06:46 Kingsy: still the wrong channel... Aug 28 08:06:58 oh lol Aug 28 08:07:07 sorry must have typed that an outpilot Aug 28 08:07:12 auto* Aug 28 08:07:18 you need root on the tablet - like you need root on *any* Linux machine to change the hostfile Aug 28 08:08:17 Leeds: got ya, I will ask around in -root Aug 28 08:20:34 hey, does anyone know, why my samsung i9003 restore data and apps on every boot? i tried to wipe it, change firmware, root / unroot... but some apps and data will always return after reboot. New installed Apps and Settings get lost after reboot. Aug 28 08:27:21 Hi Guys stupid question from a newbie.. How many broadcasts/ intents can you have on the main UI safely. Aug 28 08:28:16 <_ListerWork> question: I've looked at roboguice and I may be missing something - If I define an interface IMyInterface which has multiple implementations how can I inject the correct one in to each activity? Aug 28 08:32:01 Hello there! I'm trying to link from my app to an app on the facebook event. However, fb://event/id/ isn't working. Aug 28 08:32:09 when I want to programmatically show overlays at different situations of my app, e.g. when a video that is played in my activity reaches a certain time, is a fragment, what I want to use? Aug 28 08:32:12 What is the correct syntax/way to do this? Aug 28 08:54:40 how can I check if a GridView item has a "keyboard focus"? I've tried all sorts of isXYZ methods in my getView() for the convertView, but none of them seem to be what I'm looking for.. Aug 28 09:21:45 would like to ask again for the gurus…. is there a device that supports serial port comm access without rooting the device? tia Aug 28 09:23:16 broody: if you have usb-otg, you could use one of the usb-serial libraries Aug 28 09:24:12 the usb-otg is that dongle i need to buy right? then use their own lib to develop? Aug 28 09:24:19 thanks Ge0rG Aug 28 09:25:43 ah ok i get it, Aug 28 09:25:58 Ge0rG: but what usb-serial to use? Aug 28 09:26:21 these libraries are vendor specific isnt it? Aug 28 09:27:25 Anyone know where can i find a noob tutorial for getting specific data from a url that contain json code ? (must contain a serch bar too) Aug 28 09:28:01 neckro: what does a search bar have to do with loading json from a URL? Aug 28 09:29:20 the json data is big, that`s why i need a search bar Aug 28 09:29:46 one is a network and data-parsing question, the other is UI Aug 28 09:29:52 concentrate on one at a time Aug 28 09:30:34 so obviously you've found lots of example code on Bing for how to load and parse JSON from a URL - if you're feeling brave you could even use Volley! Aug 28 09:31:01 i`m new in coding that`s why i need a tutorial to inspire :) Aug 28 09:31:09 how new? Aug 28 09:33:36 like couple days... but i understand the coding structure... i know you normaly for what i need , i need 2 parts: src java part and layout xml part Aug 28 09:33:37 Resource name can't be the number ? Aug 28 09:33:41 such as "0.ogg" ? Aug 28 09:33:51 neckro: you're just learning java now, for example? Aug 28 09:34:06 bluesm_: I'm pretty sure that's the case, since they get turned into java variable names Aug 28 09:35:16 Leeds: So if I want to play one audio after the other. I should just concatenate string sth0.ogg sth1.ogg sth2.ogg ? Aug 28 09:36:35 um, what? no Aug 28 09:36:59 started now, yes.... but i know takes some time :) from scratch will take half year :)) so a tutorial will help me save that time... anyway after this app will be ready i will keep going to learn :) Aug 28 09:38:42 Leeds: I mean I do "onCompletion" listener. and then play the next one (sth0, sth1, sth2 and so on). Aug 28 09:39:06 which is nothing to do with concatenating strings, so yes, good luck with that Aug 28 09:40:23 Leeds: But I have to get the resource by name ? Aug 28 09:40:38 bluesm_: Wednesday Aug 28 09:40:54 neckro: please don't go off-channel Aug 28 09:41:15 i have found this : http://thinkandroid.wordpress.com/2012/09/10/parsing-json-on-android/ is exacly what i need, but need also a seach bar integrated Aug 28 09:42:08 String nameOfAudio = "sth" + Integer.toString(audioTracker++); Aug 28 09:42:12 Leeds: ^ Aug 28 09:42:22 bluesm_: August, just Aug 28 09:42:42 Leeds: What do you mean ? Aug 28 09:43:09 okay, let's be clearer, "good luck with that" was meant to mean "I'm not going to try to understand your questions anymore, so please don't ask me" Aug 28 09:43:17 ok Aug 28 09:43:34 Leeds: Thanks :) Aug 28 09:46:01 hello, I have this error in logcat "Caused by: java.lang.ClassNotFoundException: Didn't find class "com.example.android.rssfeed.MyListFragment" on path: DexPathList[[zip file "/data/app/com.example.rssfeed-2.apk"],nativeLibraryDirectories=[/data/app-lib/com.example.rssfeed-2, /system/lib]]" Aug 28 09:46:19 Please, help me troubleshooting the problem Aug 28 09:47:36 Is it a convention thing, or is there a difference between initializing instance variables in the declaration as opposed to the constructor or somethign? Aug 28 09:48:16
