**** BEGIN LOGGING AT Sat Jan 03 02:59:59 2015 Jan 03 03:00:23 so in particular, I want to stream video from my VPS. I'll need some program running on the server as well Jan 03 03:08:49 if i have AppWidgetProviderInfo of a widget is it somehow possible to get the ID of that widget? Jan 03 03:09:02 why do I get a NullPointerException from this code? numberValue is a public static int defined globally (at the top of the class). public void updateTextView() { TextView textView = (TextView) findViewById(R.id.textview); textView.setText("" + numberValue); } Jan 03 03:09:55 (not my widget, some widget installed on device) Jan 03 03:10:47 duncannz: textView is null. Also, Integer.toString(numberValue) Jan 03 03:11:17 1. Why? 2. ok Jan 03 03:11:51 duncannz: I don't know what your layout is like. you probably don't have a TextView with the id of textview in your layout. Jan 03 03:12:31 yep that was right lol. it autocompleted from a different layout. Jan 03 03:40:58 so you java people have it all wrong Jan 03 03:41:12 javascript/cordova isn't the problem, java is Jan 03 03:41:59 I just s[ent a few hours rewriting and debugging a cordova contact plugin... and they used the READ_CONTACTS permission for no good reason Jan 03 03:42:41 why? because java/android is just too convoluted and many are just stumbling around Jan 03 03:43:00 ...like ghosts in Sleepy Hollow's Purgatory Jan 03 04:08:53 stupid samsung android drivers. Jan 03 04:09:03 Agamemnus: do java like a real man or get out Jan 03 04:09:30 oooh ouch! that was harsh, shmooz! Jan 03 04:10:19 that's what he gets for dissing java Jan 03 04:10:35 glad that I dissed samsung over their dumb drivers... Jan 03 04:11:08 unless you're a samsung fan too... Jan 03 04:11:35 you only need drivers if you're on windows, anyway... and if you're on windows, it's your own fault :P Jan 03 04:12:03 nah, windows can offer what others can't. Jan 03 04:13:00 So I have a main activity which is a login screen, and then I have my "Home" activity which is the part of the app that actually "does the app stuff". Problem is, when I back out of the Home activity, it goes back to my login screen which isn't supposed to happen. What do I want to look into to stop that? The "backstack"? Jan 03 04:13:01 driver problems? Jan 03 04:13:10 you don't always have to take what's offered... Jan 03 04:13:35 Leeds: driver problems, daily reboot (altho, linux is catching up fast here), IE!, etc. Jan 03 04:14:14 I'm no fan of SameSong Jan 03 04:14:25 B0BBY: try to find the latest USB drivers for your phone Jan 03 04:14:31 Leeds: joking aside, I like manga studio, and flstudio two of my big windows programs. I switched to linux years ago but had to come back for those two. Now, I just think of each platform as offering something useful. Jan 03 04:14:46 shmooz: yeah, just downloaded the latest from samsung for note II Jan 03 04:23:26 now to see if I can get spongycastle working in my proj. Jan 03 04:35:18 So I'm calling finish() after I start an activity that takes the user away from my login screen. Pressing back exits the app, which is good. However when I open the app again it goes to the login screen... what do I need to do to make the app go to the last activity the user was on? Jan 03 04:36:14 if the login screen is the outsider case, then you should launch into your normal activity, and then have it launch the login activity Jan 03 04:37:00 So you're saying the very first activity that should open on a fresh start of the app is the normal activity, and if they're not logged in then intercept that and route them to the login activity? Jan 03 04:37:46 when adding/removing views from the hiearchary, where should i kick of an animation for example, i want the viewgroup i add to expand when its added? Jan 03 04:40:51 do I remember correctly that someone in here had frozen android studio while debugging? I can't remember who it was, but the android backstage podcast mentioned something interesting on that. Jan 03 04:43:02 t0astt: is this when you back out -> resume from recents, or resume by "launching" from home? Jan 03 05:07:57 I'm trying to build and deploy the NDK sample apps, and I'm not sure that it is working correctly. It seems like all of the apps look identical to the Hello, World app. I see the name of the activity at the top, and the text "Hello World, [activity-name]" at the top, where the activity name is different for each app since I specified a different name when I built it. Jan 03 05:08:33 But it doesn't make sense why the native-plasma app would be nothing more than a Hello World app, but I'm not sure what I've done wrong. Jan 03 05:08:58 Is anyone here more familiar with how to build the NDK samples? Jan 03 05:22:51 So, for example, after trying to build the hello-jni project, I don't see the exact output described in http://brian.io/android-ndk-r10c-docs/Getting_Started/html/index.html Jan 03 06:00:59 How does an app know which activity to start first? Does it go by whatever is named MainActivity? Jan 03 06:01:33 t0astt: day 1 tutorial stuff man Jan 03 06:01:42 Look at the android manifest Jan 03 06:01:45 GBGames, i was tryin to build the ndk samples as well.. couldnt get em to work Jan 03 06:02:12 if your trying to compile c/c++ for android i suggest using the arm-linux-gnueabi packages Jan 03 06:02:26 very simple to use Jan 03 06:04:25 bynarie: Are those packages mentioned on the android developer pages? Jan 03 06:05:05 i dont think so Jan 03 06:05:22 but its super easy to compile like a single .c or .cpp file into an executable Jan 03 06:05:45 That's good to know. Thanks! Jan 03 06:05:52 its how i was able to compile a 64 bit busybox (aarch64-linux-gnu Jan 03 06:05:53 I'll look into them. Jan 03 06:06:36 all you have to do is execute "arm-linux-gnueabi-gcc -static helloworld.c -o helloworld.out" Jan 03 06:06:42 I just wish that the NDK page at http://developer.android.com/tools/sdk/ndk/ was more accurate. The docs it mentions are not in the package I downloaded. Jan 03 06:06:55 i cant figure out the NDK... i think its junk Jan 03 06:07:05 And that's just one problem I've encountered. Jan 03 06:07:34 Well, even so, I find it very bizarre that the hello world app that appears on my tablet is not the one that should be building. Jan 03 06:07:39 all i know is that you need your files in jni folder, edit android.mk, and execute ndk-build Jan 03 06:07:42 I have no idea where that one comes from. Jan 03 06:07:58 LoL^ Jan 03 06:10:17 GBGames, what are you specifically trying to build? or are you just experimenting ? Jan 03 06:10:51 Well, my ultimate goal is to build my existing games for Android, but for now, I'm just trying to build the sample apps. Jan 03 06:11:06 I was able to get the SDK and build a hello world app there. Jan 03 06:11:13 And deploy it to my tablet. Jan 03 06:11:43 So I downloaded the SDK, I ran tools/android update sdk --no-ui Jan 03 06:11:45 yea Jan 03 06:11:48 Waited an hour. Jan 03 06:12:09 Then I followed http://developer.android.com/training/basics/firstapp/creating-project.html#CommandLine Jan 03 06:15:41 i dont know if you can build apps with the gnu cross compilers Jan 03 06:15:54 i just use it to build console programs Jan 03 06:16:38 I don't see why you wouldn't be able to do so. Jan 03 06:16:47 I mean, what else would you use? Jan 03 06:20:04 nice, finally have my phone connected to eclipse. Jan 03 06:20:17 omg u still use eclipse? Jan 03 06:20:31 switch to intellij.. much better Jan 03 06:21:01 will the community edition let you use the ADT? Jan 03 06:21:18 yes Jan 03 06:21:24 cool. TIL Jan 03 06:21:28 will it let you do NDK apps? Jan 03 06:21:30 android studio Jan 03 06:21:34 ;) Jan 03 06:21:35 yes Jan 03 06:21:40 oh? since when? Jan 03 06:21:53 android studio = intellij Jan 03 06:21:54 it seemed blissfully unaware of C sources the other day. Jan 03 06:22:02 android studio uses intellij under the hood yes, but i was asking if ideaC itself would Jan 03 06:22:26 maybe im wrong lewellyn but i believe there is a setting you have to check to set it up.. its not automatic Jan 03 06:22:38 i saw nothing related to anything not-java in the settings. Jan 03 06:22:48 ok Jan 03 06:22:57 lewellyn: iirc its a plugin. for C/C++ Jan 03 06:23:12 ddd, yes, intellij works for android apps... Jan 03 06:23:24 the actual intellij ideaq Jan 03 06:23:26 ide Jan 03 06:23:37 ddd: or i can keep using eclipse, which works better for my needs and i've got my plugins set up the same in every instance i use on every platform for every platform. :P Jan 03 06:23:47 oh the payware one or the community edition? (or both?) Jan 03 06:23:55 bynarie: I setup android studio for all new projects. this one's already workign fine in eclipse. Jan 03 06:24:10 my original problem with the phone was lack of drivers, so it wasn't visible in anything. Jan 03 06:24:18 lewellyn: I use the oracle jdk1.8.0_25 on my system. eclipse lina (4.4.1) has been having issues with it Jan 03 06:24:24 i was just kiddin, lots of ppl use eclipse still Jan 03 06:24:36 s/lina/luna/ Jan 03 06:25:08 and lewellyn, you can make c/c++ calls through NDK with gradle Jan 03 06:25:26 I'm on 64bit ubuntu linux. My windows side works fine. trying to dup on my linux side now. pita sometimes hehe Jan 03 06:26:01 screw winblows... i gave up windows completely about 2 months ago... im on linux full time now Jan 03 06:26:15 bynarie: that... isn't quite relevant to opening a .c and .h and getting something *useful* in AS Jan 03 06:26:17 i've reasons to be on windows as well. dual boot works for me Jan 03 06:26:24 bynarie: I used to try it on the emulator. then move it to a server. then copy it over wifi to the device and install. took a while doing it that way. Jan 03 06:26:29 at least both are native installs hehe Jan 03 06:26:31 ddd: i use jdk7 still. Jan 03 06:26:36 ah Jan 03 06:26:50 and my indigo install uses 1.5, iirc. Jan 03 06:27:01 i have dual boot setup too, i just dont boot to windows unless i absolutely have to... photoshop for example Jan 03 06:27:09 i cant get wine to run photoshop Jan 03 06:27:28 and i cant navigate GIMP Jan 03 06:27:30 yeah ps is .. a mess .. under wine Jan 03 06:27:36 yes it is ddd Jan 03 06:27:38 bynarie: problem with linux is lack of a seamless experience. especially with ubuntu and all variants. you're constantly upgrading the entire installation installing from scratch. Jan 03 06:28:08 im trying to get the android source files ... i have some questions about the "repo" tool , what parameters does the --groups switch take , and since im going to be builduing on linux i can pass --platform=linux right ? Jan 03 06:28:13 B0BBY, not for me.. my shit is stable and there are some package upgrades but no full system installs Jan 03 06:28:19 same here Jan 03 06:28:23 im on ubuntu Jan 03 06:28:26 14.10 Jan 03 06:28:37 its extremely seamless IMO Jan 03 06:28:40 the only issue i had was the need to install some i386 repo libs that wasn't expected Jan 03 06:28:41 bynarie: ubuntu doesn't upgrade from major version to major version without problems. the official supported position is that you must re-install. Jan 03 06:28:49 bynarie: same here. kubuntu 14.10 Jan 03 06:28:57 bynarie: and of course, you can't stay on a given version. 'coz the repos go out after a while. Jan 03 06:29:03 <-xubuntu 14.10 Jan 03 06:29:08 I was using xubuntu/ubuntu both. Jan 03 06:29:19 64bit with *very* few issues. (Just some eclipse luna + jdk8 + gtk2 icon building stuff) Jan 03 06:29:21 well im good with my setup for now Jan 03 06:29:26 well still have xubuntu installation. Jan 03 06:29:38 my server is gentoo, tho. Jan 03 06:29:48 lol gentoo Jan 03 06:29:49 ddd, you have to install a few special packages for ADB to run correctly from android studio if your on 64 bit Jan 03 06:30:00 Ok, I found something about running android sdk to download things, and even though I sat for an hour, apparently the latest system image wasn't one of the 15GB of files downloaded. Jan 03 06:30:01 B0BBY: thats utter horse crap. the repos do not go out anytime soon. hell you can still install 10 year old installs Jan 03 06:30:04 i forget which ones they are Jan 03 06:30:06 g00s: heh, every one's got their favorite distro to rag on. :) Jan 03 06:30:12 bynarie: yeah found that tidbit out the hard way hehe Jan 03 06:30:18 dood same here Jan 03 06:30:27 ddd: true but if you start out with LTS versions. Jan 03 06:30:28 it kept telling me ADB cant start or something Jan 03 06:30:32 i used gentoo for a while, maybe 5 years or s Jan 03 06:30:32 -╯□）╯︵-┻━┻ Jan 03 06:30:35 B0BBY: makes zero difference Jan 03 06:31:02 im good with any debian distro... mint, buntu, debian Jan 03 06:31:04 all good Jan 03 06:31:18 ddd: most non-LTS versions I used always ended up forcing me to upgrade due to repos being unsupported. This has been recognized by ubuntu teams and LTS versions are recommended. Jan 03 06:31:32 i've been using linux since 1994, been involved actively with the community since then, and i've worked on just about every major distrib out there as well has have my RHCE. I've yet to run against what youre saying Jan 03 06:31:40 B0BBY, yes that is correct.. LTS = recommended Jan 03 06:32:07 and having been in the community this long I can tell you thats utter horse crap. and even IF the repos DID change for the LTS its a simple sources change Jan 03 06:32:08 g00s: I started gentoo 10yrs ago or so. ended up being realy nice for my server (lightweight). desktop would be too much compiling everyday. Jan 03 06:32:24 ddd: well, then good luck to you. :) Jan 03 06:32:36 B0BBY: its worked for *years*. thank you Jan 03 06:33:00 i started out with freakin linux-mandrake when i was about 12 years old... learned how crappy it is Jan 03 06:33:12 yick, mandrake Jan 03 06:33:17 i know Jan 03 06:33:20 garbage Jan 03 06:33:24 hehehe Jan 03 06:33:44 i dont like redhat distros at all Jan 03 06:34:00 fedora suse mandriva = all crap.. IMO Jan 03 06:34:03 slack, opensuse, or (k)ubuntu for me. i stick with (k)ubuntu generally Jan 03 06:34:15 slack is good for sure Jan 03 06:34:35 i like the lightweightness of xbuntu Jan 03 06:34:56 yeah. i like kde personally. definitely heavy but i like the way its put together Jan 03 06:34:57 ddd, are you using plasma 5 or 4? Jan 03 06:35:03 think this is 4 Jan 03 06:35:19 i like kde too.. love it actually... its not too heavy, i just got used to xfce Jan 03 06:35:40 crap. give me a sec. migrating some gems from jruby 1.7.8 to 1.7.18 and one blew up on me Jan 03 06:35:50 have you used plasma5 yet? its really somethin Jan 03 06:35:57 no not yet Jan 03 06:36:06 omg its so clean looking Jan 03 06:36:16 i'm not going to touch it until its official, and its had a couple minor updates done. Jan 03 06:36:32 yea good call Jan 03 06:36:38 i am too old to go dumpster diving for broken stuff when stuff breaks Jan 03 06:36:44 haha Jan 03 06:36:53 i'd rather cut down on how much i have to ;) Jan 03 06:37:03 oh yea Jan 03 06:37:46 what kind of android devices you got? Jan 03 06:38:05 a single one that i'm doing anything with. Samsung Galaxy S5 Active Jan 03 06:38:35 i just bought the galaxy tab s 8.4 today.. its not too bad Jan 03 06:38:41 i just got nexus 9 for xmas Jan 03 06:38:46 i've a couple huawae devices i could play with too but i love my S5 so i'm focusing on it Jan 03 06:39:02 s5 is pretty new right? Jan 03 06:39:04 yeah my wife just bought me this S5. love it to death. friggin fast Jan 03 06:39:06 yeah Jan 03 06:39:37 2GHz cpu 2GB RAM, 16GB storage, can handle a 128GB microSD, blazing quick. Jan 03 06:39:55 its an arm v7a Jan 03 06:41:23 she got it for me because I'm *devastating* to my phones. I've a crapload of dogs and 2 properties to take care of. I'm forever dropping it, or the dogs grabbing it and running off with it, etc. i'm.. rough to say the least LOL Jan 03 06:41:24 not bad at all Jan 03 06:41:35 HAHA Jan 03 06:41:37 that sucks Jan 03 06:41:46 i have a drawer full of dead phones because they can't take the beating Jan 03 06:41:48 u got ne apps on the playstore? Jan 03 06:42:10 not this one though. man its taken a beating and just a TINY little ding on the right side of the casing. Jan 03 06:42:13 no Jan 03 06:42:18 i'm still learning Jan 03 06:42:29 not pushing anything out until i get a LOT better Jan 03 06:42:41 i made an app, called find root, its basically just a simple root checker, which there are already a million, but i did it just to say "I have an app on the play store" lol Jan 03 06:42:56 hahaha Jan 03 06:43:00 if you search for "bynarie" you will find it Jan 03 06:43:08 its a junk app, but i made it Jan 03 06:43:24 wow i'm tired Jan 03 06:43:37 rail --version except that its rails ;) Jan 03 06:44:07 whats that? ruby on rails? Jan 03 06:44:19 working on getting this linux install configured. covering java, ruby, javascript (node + jQuery), css, etc etc Jan 03 06:44:22 yeah Jan 03 06:44:27 i c Jan 03 06:44:39 i work on a lot of different stuff. android is the new pony in the stable for me Jan 03 06:45:32 dood, me too.. im always finding a new project to do, and never finish.. its c one day, then raspberry pi, then arduino, then android, then html, then css, then java, then linux and so on Jan 03 06:45:51 yeah. its the never finish part i'm trrying to break Jan 03 06:46:00 same here i totally get that Jan 03 06:46:17 i'm working theodinproject.com right now from start to finish Jan 03 06:46:52 that and augmenting with udemy courses on android for android programming. nothing else matters for the next 4 months Jan 03 06:46:54 but i learn something cool and it gets me geeked so i tinker for a couple weeks then lose interest and move on to another obsession.. right now im in android-obsession mode Jan 03 06:47:15 yeah, god can i obsess too Jan 03 06:47:17 sheesh Jan 03 06:47:31 hey, u made that website? theodinproject? Jan 03 06:47:47 but i don't stick long enough to get depth. i've a lot of broadness, just not a lot of depth wrt coding. Jan 03 06:48:03 I'm a deep sys admin type, but code i'm broad not deep Jan 03 06:48:09 no, i'm a user of it Jan 03 06:48:26 that is EXACTLY the same wth me.. i got a ton of broad knowledge of a ton of things but not one of them i got super deep into Jan 03 06:48:30 its the free side of The Viking School Jan 03 06:48:59 it looks like a good site Jan 03 06:49:11 its hard to hold my attention. The only thing that did was the Army. I did demolitions while I was in (Combat Engineer). Jan 03 06:49:36 is ruby and ruby on rails similar? or is it like java to javascript.. same name but totally different Jan 03 06:49:44 I did that for almost 20 years until I got hurt. All the rest of .. this stuff (computers, hardware, software, etc) I learned on the side. Jan 03 06:50:02 wow that sounds pretty exciting Jan 03 06:50:10 i havent been in military Jan 03 06:50:10 ruby is the programming language. (and interpreter). Rails is a web framework. its written in ruby Jan 03 06:50:26 oh ok Jan 03 06:51:07 rails is an MVC (Model Controller View) architecture based framework basically Jan 03 06:51:10 ddd, do you hang out on any other irc chans? Jan 03 06:51:29 im not even really sure what MVC is Jan 03 06:51:57 yeah. #java, #ruby, #ruby-lang, #rubyonrails, #rvm, #pry, #jruby, and a few others Jan 03 06:52:17 with the whole android thing, are you a rooter? Jan 03 06:52:52 when they're not under warranty ;) Jan 03 06:52:56 mine still is. Jan 03 06:53:02 true true Jan 03 06:53:26 she *just* got it for me so it will be awhile before i try to root this S5 Jan 03 06:53:35 i understand Jan 03 06:54:01 my fone is a nexus 5, so first thing i did was root and install TWRP... no warranty for me Jan 03 06:54:05 bbiam i need coffee Jan 03 06:54:15 I had a Galaxy Mega from a friend Jan 03 06:54:21 :::drinking coffee as we speak::: Jan 03 06:54:42 but the damned screen cracked. basically spider webbed Jan 03 06:54:50 ddd: how's the rails learning going? Jan 03 06:55:02 groxx: going real good. Jan 03 06:55:30 it was more active record iving me the shits. Jan 03 06:55:40 Ok, I think I see what's happening. There is this unhelpful line "Build and install the application as you would a normal Android application. " and I had to fill in the blank, and I did it wrong because the only thing I knew to do was "android create" from the hello world example. Jan 03 06:55:40 haha Jan 03 06:55:50 what kind of things can you do with rails? is it for website design, like UI elements, or code like php for connectivity ? Jan 03 06:55:52 ddd: because Active Record, or because database design? Jan 03 06:55:58 little of both Jan 03 06:56:22 cool Jan 03 06:56:30 groxx: that was for you Jan 03 06:56:33 GBGames, u get that shit compiled and working then? Jan 03 06:56:52 ddd: I figured :) database design is a little different, if you haven't done it before. Jan 03 06:56:55 bynarie: its not for design, though it makes design easier to do. its backend stuff Jan 03 06:57:24 ah ok.. i figured it was probably something behind the scenes Jan 03 06:57:36 for creating the 'guts' of a web app. though it does create the views for you (the page(s) you see and thus prettify) Jan 03 06:57:37 bynarie: it's a server + ORM + general web framework for making primarily database-backed websites. but it's pretty open-ended. Jan 03 06:58:06 ok Jan 03 06:58:33 so, kind of like a framework then Jan 03 06:58:48 well actually that was exactly what you said, a web framework Jan 03 06:58:51 groxx: and yeah, playing *in* the databases wasn't much called for in my years at this. setting them *up* was a different story. Jan 03 06:59:05 bynarie: Ok, so http://developer.android.com/tools/sdk/ndk/index.html#Reqs says to generate a build.xml, and I swear a different piece of documentation indicated I would have to do it in a directory that doesn't exist. Jan 03 06:59:08 ddd: aah, ops work? Jan 03 06:59:19 drat. I almost made an entirely three-letter-word sentence there. Jan 03 06:59:33 yeah. i'm an admin type by nature Jan 03 06:59:43 this coding stuff is me trying to break out of that mold. Jan 03 06:59:57 But holy cow, I finally got an ndk sample app to build correctly. Jan 03 07:00:04 * GBGames checks the time. Jan 03 07:00:05 its as hard to learn to be a developer as it is to be an admin Jan 03 07:00:06 * GBGames weeps. Jan 03 07:00:07 GBGames, as in the NDK stuff still? or somethin else??? Jan 03 07:00:21 ddd: well, fwiw databases seem to fit with admin mentalities pretty well, from what I've seen. though it might not be what you're using, the sqlite docs are phenomenal, and the concepts are generally the same (EXCEPT how sqlite does types. ignore that.) Jan 03 07:00:55 bynarie: I finally pieced together enough of the docs to figure out how to build it using ndk-build and the sdk and ant. Jan 03 07:00:56 stupid question but wtf is sqlite.. is it just a lightweight sql database? Jan 03 07:01:06 i see it with android apps all the time Jan 03 07:01:09 bynarie: yep. Android has it built in. Jan 03 07:01:22 groxx: well, my job has been to install and configure the engines themselves. not actually query against them other than basic info. anything *I* need, there's a TON of prebuilt (and easily modified) toolsets out there Jan 03 07:01:29 sqlite is nice because you can have it run in memory without a lot of overhead. Jan 03 07:01:35 bynarie: to be a bit more specific, it's by far the most popular embedded database software. _might_ be one of the most widely used pieces of software in the world, period. Jan 03 07:01:57 yeah in memory DBs are fast though they bludgeon your available ram to death and back Jan 03 07:02:10 really groxx ? can it be used on webservers and whatnot too? Jan 03 07:02:24 shit, youo'd be hard pressed to find where it could NOT be used Jan 03 07:02:28 bynarie: other ones are usually better for higher performance, but you can, yes Jan 03 07:02:37 Ok, I'm off to bed. Jan 03 07:02:38 hell you could use it to store a set of commands to run your toaster if you wanted to Jan 03 07:02:47 ha! Jan 03 07:02:49 your toaster probably already has it installed xD Jan 03 07:02:52 GBGames, good night Jan 03 07:02:53 Good night, and thanks for your help, and thanks for listening to me rant. Jan 03 07:02:55 groxx: lol too true Jan 03 07:03:04 thats funny Jan 03 07:03:44 ┬─┬ノ( º _ ºノ) And I'll put this back. Jan 03 07:03:53 ok, getting that coffee. also going to watch an eps or two of Revolution Jan 03 07:03:59 so if im understanding this, its sort of, in a way, like a file stored on the device used as a database.. not really for remote connections.. but im assuming it uses standard SQL language? Jan 03 07:04:00 I'm slowly moving more and more towards "don't use files for . put it in an sqlite database instead." Jan 03 07:04:16 need to step back and get away from the screen for a bit. 0200 and i've been at it since 0900 Jan 03 07:04:34 wow u need to rest ur eyes! Jan 03 07:04:49 yeah. badly. they're burning and I've definitely burnt through my focus Jan 03 07:05:05 i *might* be back tonight. if not, I'll see everyone tomorrow Jan 03 07:05:14 whatd be the difference between storing my data in, say, a text file? as opposed to using sqlite? Jan 03 07:05:22 ddd, good night... good talkin to ya Jan 03 07:05:26 bynarie: basically. it's a single-file (mostly), single-process (mostly) database. mostly for e.g. inside an application, or in a restricted environment (like your phone) Jan 03 07:05:27 same here Jan 03 07:06:00 bynarie: e.g. every browser (probably. almost certainly.) has a number of databases for storing things like your cookies, bookmarks, history, etc. Jan 03 07:06:10 they're nearly all sqlite Jan 03 07:06:34 ok ok... like titanium backup requires sqlite... is that possibly where settings could be stored? the list of apps installed Jan 03 07:07:01 i think i understand now what its for after a little explanation Jan 03 07:07:37 yeah, probably. basically, anywhere you need something more complex than you can easily store as lines in a text file, you _very likely_ want to use a database. and sqlite is so widely supported and uses so few resources, you might as well use it. Jan 03 07:07:58 ok that sounds right Jan 03 07:08:51 well, thanks for helping me understand it Jan 03 07:08:56 are all views are created after onCreateView return or can be some delay if a custom view is added Jan 03 07:09:03 sqlite also has lots of stuff in it to ensure the file doesn't get corrupted, to let you query it quickly, to make absolutely certain that things are written to disk properly on half-working systems, etc. it's better than you can do yourself. Jan 03 07:09:59 groxx, so you dont have any half-entries in the DB? like all data goes or none Jan 03 07:10:18 bynarie: exactly. it's all-or-nothing. fully transactional. Jan 03 07:10:24 ok sweet Jan 03 07:11:04 slani, what are you trying to accomplish.. more details plz Jan 03 07:11:27 it's "flavor" of sql is a little different than e.g. mysql or postgres or other "bigger" databases, but it's a "full" database. it even has full-text searching, which is how the contacts search works, for example. Jan 03 07:11:37 (that's actually an extension, but it's standard in Android) Jan 03 07:12:22 that makes sense Jan 03 07:12:59 slani, have you tried using handlers? Jan 03 07:14:21 ok Jan 03 07:21:56 bynarie: I created a custom view which is a child view of framelayout. Those framelayout also contain relativelayout where buttons will be added programmatically after onViewCreated is called. I need some position data (x, y) from custom view to set position of buttons. But problem is that buttons are created before onMeasure (here I save some x, y data) of custom view is called. Jan 03 07:22:15 bynarie: how can handlers can help in this problem Jan 03 07:24:21 slani: I'm not _entirely_ sure what you're trying to do, but that sequence is normal - layout isn't done immediately, it's done "later", which saves the system from doing work it might not need to do Jan 03 07:24:56 slani: it's fine that they're created first, you just need to move them to the right position in onLayout(Children). Jan 03 07:26:39 slani, im prolly wrong but i THOUGHT u could create like a timer or a pause with handlers Jan 03 07:26:52 im not really experienced with java Jan 03 07:26:54 groxx: ok. but how can I do that. How can I check if custom view is created? Jan 03 07:27:48 slani: it's created as soon as you inflate the xml it's defined in. that'll be immediately after setContentView(R.layout.etc), or .inflate(R.layout.etc). Jan 03 07:28:09 slani: but it won't know its size until a layout pass (or two) has completed Jan 03 07:32:14 groxx: then only solution is to create new thread and add buttons Jan 03 07:33:14 slani: nope. you just need to work with the layout system, which is what you should be doing if you're building a custom view. here's some basics: https://developer.android.com/training/custom-views/custom-drawing.html Jan 03 07:33:37 a new thread is unlikely to help you. at best it'll probably just work sometimes, but not when the device is too busy Jan 03 07:34:28 hm.. Jan 03 07:40:05 groxx: then my approach is not appropriate Jan 03 07:41:30 slani: it's possible. you can build nearly any arrangement of views with the built-in viewgroups (like RelativeLayout) - I'd suggest doing that first, it's usually easier. making custom views is pretty common though, you just have to learn how. Jan 03 07:49:15 groxx: I thought that all childs view are created after onViewCreated is called. Jan 03 07:52:10 slani: this is in a fragment? Jan 03 07:54:44 yes Jan 03 07:56:10 then all your views in your xml will exist after inflater.inflate(R.layout.your_layout, container, false). you should be able to find them and set them up. Jan 03 08:01:02 groxx: I can find them but when I try to get data from my custom view I get x = 0 and y = 0, Jan 03 08:01:23 what kind of data? Jan 03 08:02:00 becasu onMeasure in custom view is called after I creat buttons Jan 03 08:02:28 groxx: size of some objects I draw in custom view Jan 03 08:03:04 and your custom view doesn't have a width or height, right? that's because it has just been inflated, not laid out. Jan 03 08:07:02 groxx: yes Jan 03 08:07:51 how can I be sure that my custom view is laid out that I can set buttons Jan 03 08:49:41 Is there a way to get child from recyclerView dynamically? I'm trying to convert the listview screenshot method to recyclerview. Jan 03 09:24:21 groxx: ? Jan 03 09:44:08 Hi guys, I start another Activity by http://www.sourcedrop.net/Orm7b9b3009c8 I need to set callback for class ChangeNickActivity how I can do it? Jan 03 10:09:44 hmmmm Jan 03 10:10:32 how do I make a listview row have varying height (depending on whether the row has an image or not) without having that row shrink itself up before the image has loaded and end up becoming scrollable because it shrunk before all of its content loaded? Jan 03 10:11:01 I dont think it's possible Jan 03 10:12:03 varying height rows in a listview is something that exists, sure. But having the image be part of this scenario is different, cause at getView() time there's a separate thread spawning for getting hte image and by the time it returns, getView would have drawn and went back home and took a nao Jan 03 10:12:04 nap* Jan 03 10:32:35 what " p before the image has loaded and end up becoming scrollable because it shrunk Jan 03 10:32:35 "? Jan 03 10:45:05 hi Jan 03 10:45:11 happy Caturday Jan 03 10:45:57 if I have a worker thread and I want to communicate with the UI thread to make updates is a Handler the best way? Jan 03 10:48:36 handler is good Jan 03 10:48:41 lots of control Jan 03 10:48:54 but you can also keep activity reference (in aweak reference, say) and use runOnUiThread Jan 03 10:49:46 so I would call runOnUIThread from within my worker thread Jan 03 10:50:04 and create a thread within that thread to update the UI? Jan 03 10:56:15 how to access debug varaible in code? Jan 03 10:56:25 no Jan 03 10:56:48 runonuithread wraps passing the message to the ui looper via its handler through the activity Jan 03 10:57:02 you can only touch ui thread from main thread Jan 03 10:57:06 *touch ui Jan 03 10:57:39 I think just sending a message is simpler to be honest Jan 03 11:01:17 Hello o/ Jan 03 11:01:32 I have a problem with a progress ring Jan 03 11:01:39 I have two activities: A & B Jan 03 11:01:50 There is a button on activity A to launch activity B Jan 03 11:02:15 Activity B does heavy operations (doInBackground downloading a JSON, and then parses the JSON) Jan 03 11:02:36 So, I set a progress ring on activity A which starts when I do an intent of activity B Jan 03 11:02:46 However, the progress ring kind of "freezes" Jan 03 11:03:03 Do you have any idea of how I could manage to do this? Jan 03 11:03:36 erm... does activity B have a UI? Jan 03 11:03:58 Yes Jan 03 11:04:07 It has its own UI Jan 03 11:06:23 Leeds, Here si activity A: https://dl.dropboxusercontent.com/u/19626172/Activity_A.png Jan 03 11:06:30 And activity B : https://dl.dropboxusercontent.com/u/19626172/Activity_B.png Jan 03 11:07:02 I access activity B thanks to the button "Accéder à la liste" Jan 03 11:09:10 Hum Jan 03 11:09:28 I should try to do my heavy stuff in the onStart() method Jan 03 11:11:55 Hum... not better Jan 03 11:15:10 Encrypt: maybe use a thread to do background operation and update the UI with runOnUIThread (not sur of the exact name) method to update activity B Jan 03 11:15:44 Schoumi, The background operation is an AsyncTask already :/ Jan 03 11:15:48 arf Jan 03 11:16:37 Schoumi, https://github.com/Zencrypter/App_mobile/blob/master/Beerlover/app/src/main/java/com/pereiraprive/beerlover/MainActivity.java Jan 03 11:16:41 My problem is line 67 Jan 03 11:17:09 And here is the BeerList activity: https://github.com/Zencrypter/App_mobile/blob/master/Beerlover/app/src/main/java/com/pereiraprive/beerlover/BeerList.java Jan 03 11:18:55 Hum what's the thread line 92 wants to do? Jan 03 11:21:17 Schoumi, That's the progress ring Jan 03 11:21:44
