**** BEGIN LOGGING AT Sun Feb 15 02:59:59 2015 Feb 15 03:00:09 lasserix_: depends on what you mean by later Feb 15 03:00:30 TacticalJoke: i dont know how i can do that. with debugger? Feb 15 03:00:39 with the display list system it's not going to help you much unless you actually destroy the views and unload their data Feb 15 03:01:05 john67: Are you using Android Studio? Feb 15 03:01:15 TacticalJoke: yeah Feb 15 03:01:15 romainguy: ah ok thanks Feb 15 03:01:53 john67: Just remove all filters. Then you can perhaps type "exception" in the search bar to make it easier to find the exception stack trace. Feb 15 03:11:19 Hmm, I wonder whether we'll be ever able to use JUnit 4 for instrumentation testing. Feb 15 03:11:32 (Or TestNG!) Feb 15 03:14:29 romainguy: if i have to persist the data of a bunch of views (mostly just text) what's the best way to persist the data? is there something closer than dumping into an sqlite table I can do (closerto the view hierarchy mechanics like what on save instance state does) Feb 15 03:15:10 eg, i have weather updates. the views should always show the most recent weather update (even if it days old) Feb 15 03:16:16 right now i have a ds that is just java that allows the views to bind to the raw data, which i can stow in a table or whatever, but was wondering if there is something in the sdk that is closer to the view hierarchy mechanics that i can use to persist that would be faster or more efficient Feb 15 03:16:49 (since parcels and bundles for save/restore instance is just for within an app cycle, not between) Feb 15 03:19:36 lasserix_: Did you see this (although it's 21 only)? http://developer.android.com/reference/android/app/Activity.html#onRestoreInstanceState(android.os.Bundle, android.os.PersistableBundle) Feb 15 03:20:01 ahh that's awesome but need 16+ Feb 15 03:22:36 wow, an N6 will be mine xD Feb 15 03:30:08 hey tacticaljoke you told me that one fragment calling on each other directly is bad design, you mean nested fragments not transitioning from fragment to fragment via activity manager, correct? Feb 15 03:34:12 err TacticalJoke: Feb 15 03:40:06 well... one fragment calling another could have surprises, given async fragment transactions (you could be calling an old one, for instance). but if the fragments don't change / that's just not possible due to other parts of your app, it seems like it should be fine? worth testing pretty thoroughly at least. Feb 15 03:43:32 TacticalJoke: I’m so very sad about the state of testing Feb 15 03:43:55 oh hi romainguy :) Feb 15 03:54:30 how would I apply the kexec-hardboot patch to franco kernel? Feb 15 03:54:49 for the nexus 7 2012 Feb 15 03:57:53 #android-root Feb 15 03:58:23 p_l: thats not a root question though... Feb 15 03:59:03 it's not in an .apk and it won't work on a normal non-rooted / non-modified device -> #android-root Feb 15 03:59:07 codebam: well, it's the closest generic channel to the topic involved. Here is mostly about application developement Feb 15 03:59:36 p_l: okay thanks Feb 15 03:59:42 groxx: okay Feb 15 03:59:45 thanks Feb 15 04:14:33 TacticalJoke still there ? Feb 15 04:24:22 can i hide left and right elevation on card view? Feb 15 04:34:43 cbeust: hey :) Feb 15 04:48:46 g00s: Yeah. Feb 15 04:49:08 TacticalJoke figured it out, no worries Feb 15 04:49:10 thx Feb 15 04:49:20 cbeust: Yeah, it's not great. I'm glad the Gradle plugin now supports JVM unit testing, though. Waited so long for that. :) Feb 15 04:52:19 wow ho i think i finally got the answer to that damn interview question Feb 15 04:52:35 Which one? Feb 15 04:52:53 how would you answer "what is object oriented programming? Feb 15 04:53:13 my answer did not satisfy me so i've spent the last couple of weeks trying to come up with a single statement that would satisfy me Feb 15 04:53:44 Yeah, I'm not satisfied with my answer, either. Not sure how much weight to give polymorphism, for example. Feb 15 04:53:57 that's being too specific i think Feb 15 04:54:05 so there is a great answer by steve jobs on quora Feb 15 04:54:14 steve ? Feb 15 04:54:20 and then the creater of c++ in a paper entitled what is object oriented programming Feb 15 04:54:24 I guess talking about state and behaviour is important? Feb 15 04:54:50 points to the fact what really defines oo is the fact an object can know its local behavior in refrence to its general behavior Feb 15 04:54:58 yeah Feb 15 04:55:11 so dont laugh but here's my answer: "Object oriented programming is a technique of writing code that encapsulates complexity by enumerating Feb 15 04:55:11 data structures with an intrinsic implementation so that they can generally interface." Feb 15 04:55:21 hehe Feb 15 04:55:29 O.o Feb 15 04:56:12 Using 'interface' as a verb... hmm. Feb 15 04:57:19 OO is a method of coding ontology Feb 15 04:58:45 Sometimes, the most natural things are the hardest to define. Feb 15 05:03:24 lasserix_ you could also go with kay http://userpage.fu-berlin.de/~ram/pub/pub_jf47ht81Ht/doc_kay_oop_en Feb 15 05:03:36 "OOP to me means only messaging, local retention and protection and hiding of state-process, and extreme late-binding of all things." Feb 15 05:03:36 I was just reading that page. haha Feb 15 05:03:41 Just about to paste that. Feb 15 05:03:48 state-prcoess is probably actor model Feb 15 05:04:23 I kinda like Mozilla's summary: "Object-oriented programming is a programming paradigm that uses abstraction to create models based on the real world." Feb 15 05:04:26 Though it doesn't say much. Feb 15 05:04:35 lasserix_ fwiw, back in the 90's when OO was a big thing, there was a gathering ... haha ... where they tried to pin down a definition. nobody really agreed on anything. but a few things did come out as common ground Feb 15 05:05:01 they like booch, rambaugh, paje-jones, etc Feb 15 05:05:33 This is an key point: "Object-oriented programming may be seen as the design of software using a collection of cooperating objects, as opposed to a traditional view in which a program may be seen as a collection of functions, or simply as a list of instructions to the computer. " Feb 15 05:05:41 not that OO failed, but seems like the trend now is mixing OO + functional Feb 15 05:05:58 s/an/a/ Feb 15 05:07:20 Hey, drose379. I was AFK earlier. Feb 15 05:07:40 What did I say? I forget Feb 15 05:08:03 Something like "Hey, TacticalJoke". Feb 15 05:09:10 Ah, ok Feb 15 05:09:12 No prob, whats up? Feb 15 05:09:36 Not much. Just deferring sleep for some reason. Feb 15 05:10:02 Im really tired too Feb 15 05:10:12 Sl Feb 15 05:10:15 Oops Feb 15 05:10:26 Any progress with the app? Feb 15 05:10:42 is there any way for changing the white menu background in android 5.0.2?? Feb 15 05:10:44 I only did a little refactoring today. Was so tired. Feb 15 05:11:08 XxOblivionxX: Which menu? Feb 15 05:11:31 main menu. Feb 15 05:11:57 The overflow menu of a Toolbar? Feb 15 05:12:20 I meant the main menu that shows apps Feb 15 05:12:51 I think it's the "app drawer", but I'm not sure. Feb 15 05:13:24 yeah. that's it.I didn't know how it was called Feb 15 05:13:31 g00s yeah espicailly with what rx java is all about Feb 15 05:13:42 is there any way for that brother?? Feb 15 05:14:09 XxOblivionxX: you mean you want to customize your rom? Feb 15 05:14:18 thats probably an android-root question Feb 15 05:14:46 Another option would be to use a custom launcher, I guess. But, yeah, it's not really this channel's topic. Feb 15 05:15:08 ok.thank you for the information. Feb 15 05:15:18 There is #android and #android-root, I think. Feb 15 05:15:25 oh yeah custom launcher is easier choice Feb 15 05:15:37 drose379: How 'bout you? How's the app coming along? Feb 15 05:15:39 oh nice link g00s thanks Feb 15 05:16:08 Oh, there's a tiny bit of Fragment-versus-View drama on /r/androiddev. Feb 15 05:16:17 TacticalJoke not bad, changed around a few of the icons today and ive been trying to get the tag feature implatmented Feb 15 05:16:44 http://www.reddit.com/r/androiddev/comments/2vvv6q/how_do_you_reuse_components_without_using/ Feb 15 05:16:49 Nice. I love the tag idea. Feb 15 05:17:08 You do? Feb 15 05:17:53 Yeah, tags are a powerful grouping mechanism. Feb 15 05:18:15 Cool, thank you Feb 15 05:18:19 Hi Feb 15 05:18:34 hi Feb 15 05:19:25 drose you going to use a denormalized db to handle your tags? Feb 15 05:19:37 Is there any good docs on how to do simple tabs? Feb 15 05:19:43 denormalized? Feb 15 05:19:47 s/Is/Are Feb 15 05:19:54 Trying to access my string resources from a non-activity class. There's a million people on stackoverflow telling me to "just pass the context" and one guy who says, it shouldn't be done by passing the context because that's bad style. What's recommended? Feb 15 05:20:27 static application context Feb 15 05:20:32 teegee: I think the best approach depends on the nature of your class. For example, you could pass the Resources object. Feb 15 05:20:34 each table is self contained, you don't shove all your data into a central table. that way you have a table of tags, whose primary keys you can use as foreign keys in another table, and create a mapping.. so like lessons table will have column, tags, which you can look up and vica versa Feb 15 05:20:49 Or you could pass the string(s) itself/themselves. Feb 15 05:20:55 TacticalJoke: it's a FragmenPagerAdapter Feb 15 05:21:04 Yeah lasserix_ thats how I have it set up so far Feb 15 05:21:14 Lessons in one table, Subjects in another, tags will be its own table Feb 15 05:21:27 teegee you could use a static class you just initialize on application class oncreate, just pop all your strings into it and then you can access them anywhere Feb 15 05:21:44 drose379: yeah thats the idea Feb 15 05:22:16 Cool, thanks lasserix_ Feb 15 05:22:37 lasserix_: It's sad that you received this question in an interview, not sure what the interviewer was looking for Feb 15 05:22:41 TacticalJoke: i just wish there was a view backstack library Feb 15 05:22:55 deuteros__: tbh he was kind of a dick/ condescending the whole interview Feb 15 05:23:02 AS doesn't show you empty folders in Android view. If I have to create a folder then I have to switch back to other view like Project. Is that how it works? Feb 15 05:23:27 i don't have a degree i think the entire team there did so... Feb 15 05:23:29 g00s: I would not go with Kay for the definition of OO, he's been trying to redefine the meaning ever since he came out of his cave and decided he cared about OO after not caring for several decades :) Feb 15 05:24:05 lasserix_: :\ that's sad. interviews should be fun, IMO Feb 15 05:24:15 i actually like paje-jones definition the most, i just can't find it Feb 15 05:24:16 nah it was a serious interrogation Feb 15 05:24:52 lasserix_: doesn't surprise me Feb 15 05:24:55 lasserix_: is there an easy way to clone my strings into a static class by deriving it from something or do I have to populate everything manually? Feb 15 05:25:21 teegee: there might be a way to iterate over all your string resources, not sure Feb 15 05:25:36 that counts as manual :) Feb 15 05:25:49 ok, I'll go with the static class. thanks Feb 15 05:26:09 teegee: Do you have a link to the SO questions? Just curious Feb 15 05:26:25 Is it correct though, that the context shouldn't be passed around unless there's a better reason? Feb 15 05:27:03 lasserix_ you could also look at bertrand meyer's definition Feb 15 05:27:27 teegee, no Feb 15 05:27:34 g00s link? Feb 15 05:27:40 TacticalJoke: http://stackoverflow.com/questions/7666589/using-getresources-in-non-activity-class Feb 15 05:27:49 it's in the comments Feb 15 05:29:18 lasserix_ well, its probably burried in http://en.wikipedia.org/wiki/Object-Oriented_Software_Construction ... which nobody would buy in 2015 :D Feb 15 05:29:43 It's sad to hear Alan Kay say that he finds type systems "painful" Feb 15 05:29:53 you can tella lot by the programming <-> software construction ;p Feb 15 05:30:05 TacticalJoke: what he suggests sounds very much like the "copy stuff in static class" approach to me Feb 15 05:31:33 "You will have to pass a context object to it" is just wrong. The OP could alternatively pass a Resources or an XmlPullParser (lol) or the end product of whatever operation is going on. Feb 15 05:33:57 Although since we're talking about an adapter, is passing a Context to it such a bad idea? Adapters are very UI-related. Feb 15 05:34:54 I pass Contexts all the time to my list adapters, and they do stuff such as extract LayoutInflaters from them. Feb 15 05:34:56 TacticalJoke: The risk is that a Context might be an Activity or an Application (odd inheritance choices) and if you end up holding one to it somehow (e.g. storing it in a static field), memory leak Feb 15 05:35:29 also passing in the wrong context if you are using it to pull a theme/style can screw you up Feb 15 05:35:44 This kind of leak shows up pretty quickly in a memory profile dump, though Feb 15 05:36:15 TacticalJoke, certain adapters already have built in getContext() functions Feb 15 05:36:26 like http://developer.android.com/reference/android/widget/ArrayAdapter.html#getContext() Feb 15 05:37:16 yiati: wouldn't that require you had already initialized it with a context? Feb 15 05:37:23 Yeah, in the constructor. Feb 15 05:38:03 lasserix_ certain adapters such as ArrayAdapter will not allow you to instantiate one without a context Feb 15 05:41:27 Im out for now TacticalJoke Feb 15 05:41:30 Talk to you later Feb 15 05:41:50 Later. Feb 15 05:54:43 how long should it take to compile the android ndk? (yes ndk, not sdk) Feb 15 05:55:24 a while. it's got to compile gcc at least twice. Feb 15 05:56:04 does this code look like an efficient alternative to sharedpreferences for Lists? or is there a better way to store lists via sharedpreferences? https://github.com/kcochibili/TinyDB--Android-Shared-Preferences-Turbo/blob/master/TinyDB.java Feb 15 05:56:54 oh nvm I can use a friggin set Feb 15 05:57:20 TheKarlBrown: What are you trying to achieve? Feb 15 05:57:30 storing favorites locally Feb 15 05:57:40 do not use that Feb 15 05:57:41 and set is actually BETTER than a list for that purpose Feb 15 05:57:42 wow karl thats pretty cool Feb 15 05:57:54 You're using SharedPrefernces internally, how can this be more efficience than SharedPReferences? Feb 15 05:58:13 deutros what? Feb 15 05:58:18 lasserix is that sarcasm Feb 15 05:58:26 (and returning 0 if you can't parse a string into a number? Terrible idea) Feb 15 05:58:51 + Feb 15 05:59:05 oh its sp not sqlite Feb 15 05:59:17 okie, so set it is then Feb 15 05:59:21 Also line 45 Feb 15 05:59:24 mContext = appContext; Feb 15 05:59:33 mContext = appContext.getApplicationContext() Feb 15 05:59:34 lewellyn: like more than half an hour on a sandybridge i5? Feb 15 05:59:56 lasserix I'll be using sqlite later I thinks Feb 15 06:00:30 codebam: probably. Feb 15 06:00:38 If you're using sqlite, you can be certain it won't be "more efficient" than SharedPreferences Feb 15 06:00:56 cause my pc has stopped responding altogether for the past half hour Feb 15 06:01:02 will not be for preferences Feb 15 06:01:12 TheKarlBrown, make sure that whatever Context you store in there is application context, and not an activity context by calling .getApplicationContext, or you are asking for crazy memory leak Feb 15 06:01:26 will be for processing filters for data pulled from a mysql database Feb 15 06:01:52 yiati are you talking about the code I linked or when I'm using shared preferences Feb 15 06:02:04 The code you linked Feb 15 06:02:26 because currently I grab it in mainactivity then reference it in fragments by getActivity().sharedPref Feb 15 06:02:49 code I linked was instaveto'd Feb 15 06:02:57 ? Feb 15 06:03:05 after rejection by hivemind + discovery of ability to save sets which does it better than planned Feb 15 06:05:34 i am trying to understand this data / presentation / domain pattern, what is in domain in android context? Feb 15 06:06:20 what? Feb 15 06:06:38 What's the data/presentation/domain pattern? Feb 15 06:06:46 Model View Controller? Feb 15 06:06:49 for instance http://fernandocejas.com/2014/09/03/architecting-android-the-clean-way/ Feb 15 06:06:52 no Feb 15 06:07:01 ~ not exactly Feb 15 06:08:04 lewellyn: I'll leave it on overnight then and it should be done by morning... right? Feb 15 06:08:34 hey TacticalJoke you here? Feb 15 06:09:42 codebam: likely. Feb 15 06:10:14 lasserix_: looks like according to that article that "domain: A java module without android dependencies." Feb 15 06:10:47 so it doesn't seem likey domain has anything to do with Android context Feb 15 06:11:20 i dont mean context Feb 15 06:11:24 i mean in android programming Feb 15 06:11:37 i dont mean "android context" i mean in the context of android Feb 15 06:11:42 sorry Feb 15 06:11:43 ah lol Feb 15 06:12:06 Given the context of this irc channel it's hard to tell with context Feb 15 06:12:17 which* Feb 15 06:13:22 thank you Feb 15 06:14:20 Well you can make plenty of code that processes data, whether it's models or even controllers that don't necessarily know anything about Android so in the context of Android anything that fits those criteria would be in the "domain" in this architecture Feb 15 06:15:40 but the point is to bridge the data and presentation with the domain? Feb 15 06:16:25 so like if i am building a weather app, the data from the web servers goes into the data, presenting it goes into presentation with its views, and verifying whether a report is still valid is the domain? Feb 15 06:17:48 looking at the code it looks like he just uses it to to do hypothetical test cases Feb 15 06:17:52 lasserix_ sounds right to me Feb 15 06:18:43 getting a nice clean presentation layer always seems to be the tricky part to me Feb 15 06:19:18 thats what i mean, it looks like you can bridge data - presentation by just using a presenter buffer between data and view Feb 15 06:20:19 Ah are you saying you don't understand why domain is necessary? Feb 15 06:20:27 no more like what it is Feb 15 06:20:37 that's why i was asking about the weather example Feb 15 06:20:44 Well in that article they are saying it's the business logic Feb 15 06:21:14 yeah your weather example sounded right to me Feb 15 06:22:18 Hey everyone, I'm trying to add tabs to my app. I've converted it based on this howto ( http://www.androidhive.info/2013/10/android-tab-layout-with-swipeable-views-1/ ) but I can't see the actual tabs. I can see the fragments in the tab, and I can swipe between them, but the actual tabs are missing Feb 15 06:23:42 lasserix_ thanks for that link I will have to read into more later Feb 15 06:28:02 later Feb 15 06:28:18 night Feb 15 06:28:19 thanks Feb 15 06:28:32 anyone seen a library for making animation drawable sequence controllable like a media player? Feb 15 06:36:57 Hey guys how do you communicate from an app to a database securely? I've never done anything like this. My friend told me something about using jwt? Any commments? Feb 15 06:38:50 Database on the client or server? Feb 15 06:39:28 deuteros__, communicate to a server Feb 15 06:39:44 if you make avd via command line, how do you make the avd manager in androidStudio find it? Feb 15 06:39:52 deuteros__, not locally.. is that what you meant? or did I misunderstand? Feb 15 06:40:12 gopar: Then you need a server and you communicate with it with something like json (or protobufs Feb 15 06:55:44 would /storage/emulated/0/Download/lol be the location of lol in downloads in my sd card? Feb 15 06:59:59 nvm crazy question for some reason files didn't appear until I rebooted zee phone Feb 15 07:05:55 not flushed? Feb 15 07:09:49 gopar: ! Feb 15 07:09:52 g00s: ! Feb 15 07:11:30 thepoosh, im guessed you called the wrong person? Feb 15 07:11:38 yeah, sorry mate Feb 15 07:11:43 but HI!!! Feb 15 07:12:08 thepoosh, ha HI :D Feb 15 07:12:23 * thepoosh is sorry for the hastle Feb 15 07:13:17 napster: hi dude Feb 15 07:13:31 oh hey thepoosh :) whazzup? Feb 15 07:13:36 mmmkay Feb 15 07:13:45 ordered a OnePlus One last week Feb 15 07:13:55 I'm setting up a mail server here! Feb 15 07:13:59 OnePlus cool Feb 15 07:14:17 mail server?! Feb 15 07:14:18 Sleek phone isn't it? Feb 15 07:14:42 yep, had one domain, so working out a postfix-dovecot-webmail setup Feb 15 07:14:57 hey thepoosh Feb 15 07:15:05 09:13 thepoosh: ordered a OnePlus One last week Feb 15 07:15:12 here comes the legend g00s :) Feb 15 07:15:23 lol Feb 15 07:16:30 I will need to develop an IMAP client on android Feb 15 07:16:49 thepoosh hows the device? Feb 15 07:17:00 shipping Feb 15 07:17:09 API-21 right? Feb 15 07:17:16 shipped yesterday from CA to Chicago Feb 15 07:17:27 and then will start shipping to Israel Feb 15 07:17:32 will be Feb 15 07:17:37 it runs CM Feb 15 07:17:46 I see Feb 15 07:17:48 Are the onePlusOne officially on sale now? Feb 15 07:18:14 I thought it run stock android Feb 15 07:18:23 nah Feb 15 07:18:33 deuteros__: on Teusdays Feb 15 07:18:39 but i got an invite on FB Feb 15 07:20:54 will be interesting to see what fruit comes of MS investing in CM Feb 15 07:20:58 someone needs to introduce collapsing/expanding text blocks in html rendering Feb 15 07:25:18 MS invested in CM?! Feb 15 07:25:29 70M Feb 15 07:25:34 defaq! Feb 15 07:25:44 well, to put their apps on there probably :D Feb 15 07:25:48 they know they cant do hw so they are angling for software integration Feb 15 07:26:07 you Feb 15 07:26:23 you'll probably get a subscription to cm with ms with your cell phone contract ;p Feb 15 07:51:04 CM? Feb 15 08:04:16 phix: http://www.cyanogenmod.org/ Feb 15 08:04:51 hi, I want to start an intent that requires permissions from adb, for example "adb shell am start -a android.intent.action.SET_ALARM". How can I tell him that he has the permissions to do this from adb?

Feb 15 08:25:41 O.o Feb 15 08:26:09 if there isn't enough commitment to dl through play, it should be a webapp that isn't installed :) Feb 15 08:26:33 "iOS is where the revenue and early-adopters are" Feb 15 08:26:48 wait i'm on android using java 6-7, aren't i an early adopter :D Feb 15 08:27:35 lasserix_ the idea of swift on android is interesting though Feb 15 08:27:44 yeah Feb 15 08:27:50 tho ive heard some parts of swift are a pos Feb 15 08:28:09 like you have to cast elements out of a collection and such or something like that Feb 15 08:28:55 Did you see this? http://arxiv.org/abs/1502.01410 Feb 15 08:29:05 95% of java code on bickbucket sampled is redudent Feb 15 08:30:21 yeah, getters and setters, etc Feb 15 08:30:24 "Shah: Greater and more flexible UI controls on Android would be very helpful." Feb 15 08:30:30 man i've been saying this for years Feb 15 08:30:51 have you seen view flow or flowvie? Feb 15 08:30:59 but what do you mean UI controls? Feb 15 08:31:55 still reading, once sec. " That’s why almost all of the top 100 Android apps use the Android NDK to optimize their app. " wonder if that is true Feb 15 08:32:24 yeah Feb 15 08:33:48 all those guys said build for apple watch Feb 15 08:34:11 not sure Feb 15 08:34:13 lasserix_ when i did ios dev a while back , the catalog of UIKit widgets was >> Android's Feb 15 08:34:19 ahh Feb 15 08:34:43 google proabbly suspected android devs would publish more libraries since open source Feb 15 08:34:56 but they should encoruage it and make a whole subsection Feb 15 08:35:06 devoted to dependencies for devs by devs for ui ;p Feb 15 08:35:23 probably also helped along by e.g. cocoapods. we've been stuck with Eclipse until recently :| Feb 15 08:35:26 not great for code-reuse. Feb 15 08:35:33 oh yeah Feb 15 08:35:35 definatly Feb 15 08:36:02 hi everyone Feb 15 08:36:35 g00s --> apple phone because you could probably make a killing on some car related widget Feb 15 08:36:46 whena pple releases their car or whatever auto it is theyare doing Feb 15 08:37:47 `gradle build` fails with error: package R does not exist. but mvn package does his work well. R has links to all variables and templates. How to force gradle understand this ? Feb 15 09:03:43 this https://appetize.io infact is pretty good I think Feb 15 09:04:40 if they release a home launcher (with all the apps available in their... so called store...) one can start using apps right away. Feb 15 09:05:01 without downloading none. Feb 15 09:16:34 I've got 2 tabs (fragments) in a ViewPager in my main activity. When I change from one tab to the other, is the currently shown fragment object destroyed and the new one created? Feb 15 09:16:49 Or do they survive once they're created Feb 15 09:17:56 one left, the current and the right are 'cached' Feb 15 09:18:10 so in your case they shouldnt be destroyed Feb 15 09:18:42 good Feb 15 09:19:33 depends Feb 15 09:19:37 on which adapter Feb 15 09:19:51 if it contains the word state in the adapter name then it is alwasy destroyed Feb 15 09:19:55 now, when I change a setting in my SettingsActivity, I'd like to pass the new value to both objects. What's the best way to do that? Feb 15 09:19:56 and recreated Feb 15 09:20:17 abstract the view state and present it Feb 15 09:34:17 hi there Feb 15 09:34:38 I have an issue with a menu on a viewpager Feb 15 09:35:31 when I go to another fragment, and click on back button to return to pager fragment Feb 15 09:35:43 the menu disappear although the toolbar seems to be populated Feb 15 09:35:43 lasserix_: I'm not sure I know what you mean. I can get the Fragment from the FragmentManager but I can't cast it to my specific class so I can call methods on it Feb 15 09:36:03 fragment has a call present Feb 15 09:36:07 which takes whatever data Feb 15 09:36:08 and presents it Feb 15 09:36:22 oh, ic Feb 15 09:36:56 you implicetly generally do this onCreateView or whatever, but if you make a dedicated method (or interface) to state invalidation for your views Feb 15 09:37:18 then you can always have a solution to things like user changes display preferences without respect to which detail Feb 15 09:39:42 what am I doing onCreateView? Load stuff from the settings? Feb 15 09:39:55 umm Feb 15 09:39:56 i dont know Feb 15 09:40:07 but usually people set up their view references, and load whatever initial data they want to display Feb 15 09:40:19 yes Feb 15 09:40:39 i am just saying if you give your fragment a present() command, then it should take whatever it is responsibility for showing, and update its state accordingly Feb 15 09:40:55 my fragment doesn't offer a present() Feb 15 09:43:50 this is the android.app.Fragment you're talking about or the android.support.v4.app.Fragment? Feb 15 09:44:08 no Feb 15 09:44:10 you add it Feb 15 09:44:14 but oyu asked how to transfer data Feb 15 09:44:20 so im asnwering the wrong question Feb 15 09:44:30 but you can just pass it as a buncles arguement Feb 15 09:44:35 but how can I call it if I don't have the specific class object? Feb 15 09:45:14 if a setting is changed then it means the fragment will have to be redisplayed Feb 15 09:45:42 oh Feb 15 09:45:42 http://developer.android.com/reference/android/content/SharedPreferences.OnSharedPreferenceChangeListener.html Feb 15 09:45:45 you could use that Feb 15 09:46:54 i dont know how you start your settings activity Feb 15 09:46:59 but you could use activityForResult Feb 15 09:47:25 yes, I've got the onActivityResult overwritten Feb 15 09:47:39 this is where I'm trying to call my Fragments' methods Feb 15 09:48:03 so you go activityA with tabs to activityB with settings, then you return from B to A? Feb 15 09:48:12 and thats when you are trying to call your fragments? Feb 15 09:48:28 that's why i am saying add a method present which makes the fragment updates its view state Feb 15 09:49:10 can an activity have both settings and tabs? Feb 15 09:49:16 sure Feb 15 09:49:24 good, that's what I'm trying to do :) Feb 15 09:49:49 so I'm not changing activities, just changing tabs Feb 15 09:50:05 one tab is settings? Feb 15 09:50:12 oh Feb 15 09:50:14 i see Feb 15 09:50:20 the settings are a new activity Feb 15 09:50:31 so yes, you were right :) Feb 15 09:52:12 so I've added a method to my fragment. Let's call it update() Feb 15 09:52:56 and in main main activity, which has the tabs, I've gotten hold of the fragment from the fragment manager Feb 15 09:54:07 but because the fragment manager returns a Fragment class, and not a MyFragment class which extends the Fragment class, I can't call .update() Feb 15 09:54:23 and it won't let me cast it Feb 15 09:54:43 am I thinking the wrong way? Feb 15 09:55:53 yes you can cast it Feb 15 09:56:06 just make sure you have it referenced correctly ie Feb 15 09:56:19 Fragment mFragment = fragMang.et(TAG) Feb 15 09:56:40 you need to MyAwesomeFragement f = (MyAwesomeFragement) fragManager.get(TAG) Feb 15 09:57:00 \\\\\\\\ Feb 15 09:57:07 hm, I used findFragmentById Feb 15 09:57:43 nj\wahatever it doesnt matter does it\\ Feb 15 09:58:04 that was just an example Feb 15 10:00:08
