**** BEGIN LOGGING AT Sat Sep 06 02:59:59 2014 Sep 06 03:23:38 linearlayout does that Sep 06 03:28:23 hello all Sep 06 03:28:52 pfn: can you elaborate? Sep 06 03:29:11 layout weight and height Sep 06 03:30:04 relative layout would do it too Sep 06 03:41:51 pfn: How do I programmatically add a fragment with a FragmentTransaction and also set its weight? Sep 06 03:42:33 you set it on the container you add it into Sep 06 03:43:36 right now I have this... point me in the right direction? http://pastebin.com/P9gCm5xn Sep 06 03:43:52 R.id.container is a LinearLayout Sep 06 03:48:40 should work Sep 06 03:49:11 It works, I just don't know how to set the gravity of the Fragments I'm adding Sep 06 03:50:02 what do you want to do ? Sep 06 03:50:03 exactly Sep 06 03:50:34 I want the media buttons fragment to take up the bottom 72dp of the screen, and for the channelfragment to take up the rest, above it Sep 06 03:50:58 http://stackoverflow.com/questions/3775705/android-set-the-gravity-for-a-textview-programmatically Sep 06 03:51:33 and what you want Sep 06 03:51:42 Probably relative layout is better anyway Sep 06 03:52:15 aling_toBottom or whatever it was Sep 06 03:52:21 alingParentBottom ? Sep 06 03:52:48 you can't do what that SO answer linked with a fragment Sep 06 03:53:10 MediaControlsFragment mediaFragment = new MediaControlsFragment(); mediaFragment. //dot what? Sep 06 03:53:35 A relativelayout would be wasteful for this Sep 06 03:53:58 relativelayout is faster Sep 06 03:53:59 but Sep 06 03:54:05 mediaFragment.setGravity ? Sep 06 03:54:11 not a method Sep 06 03:54:13 but way... Sep 06 03:54:17 *wait Sep 06 03:54:51 it doesnt make sense Sep 06 03:55:06 what you want is to set weight Sep 06 03:55:15 one to 0.7 and second to 0.3 Sep 06 03:55:17 or whatever Sep 06 03:55:26 true, but that's also not an available method Sep 06 03:55:57 you need to get LayoutParams first Sep 06 03:56:02 and then set weight to them Sep 06 03:56:06 http://stackoverflow.com/questions/3224193/set-the-layout-weight-of-a-textview-programmatically Sep 06 03:56:41 setLayoutParams also isn't a method of Fragment. Sep 06 03:57:17 http://stackoverflow.com/questions/12224433/can-i-set-layoutparams-to-fragment-by-programming Sep 06 03:57:19 maybe fragment.getView().setLayoutParams? Sep 06 03:57:38 okay, yeah Sep 06 03:57:47 let me try that Sep 06 04:01:07 ah damn it, I'll just use a relativelayout. Trying to figure out the dp -> weight conversion is too much work Sep 06 04:10:26 lol Sep 06 04:22:07 Is there a way to use fragmenttransaction to "stack" one fragment on top of another when calling add rather than simply overlapping them? Sep 06 04:25:57 nevermind, I'm dumb. Was using a framelayout that AS generated for me Sep 06 04:27:40 guys, there is any way to run code only if the device api is greater than a desired value Sep 06 04:29:26 you can use Build.VERSION to get the API level Sep 06 04:32:32 How can I change the background of this ListPreference? http://i.imgur.com/xlBcR6h.png Sep 06 05:11:12 Hey guys I was wondering, instead of stement returning true or false, is ther e a way I can make it return yes or no instead? Sep 06 05:11:23 statement* Sep 06 05:16:16 return a Sting? Sep 06 05:17:29 well basically im doing an if statement, and I just want on string to be filled with either yes or no depends on the if stement conditions and return it in a output Sep 06 05:17:56 thats basic java Sep 06 05:18:21 I still cant figure it out since I never had a reason for it. Sep 06 05:18:36 if(boolean) return "yes" else return "no" Sep 06 05:18:41 how can you not figure that out Sep 06 05:19:08 so I can put return "yes" instead of true? Sep 06 05:19:11 its that simple? Sep 06 05:19:22 your method would have to return type string Sep 06 05:19:41 return expression ? "yes" : "no" Sep 06 05:19:45 is a one liner Sep 06 05:19:55 actually I think I just got it. hold on Sep 06 05:20:05 this isnt difficult Sep 06 05:21:10 desming how long have you been programming in java? Sep 06 05:21:16 http://pastie.org/9531080 Sep 06 05:21:26 couple years Sep 06 05:21:38 I'm trying to do google oauth from scratch - it responds with error code 599 every once in a while. Does any one know what that means? Sep 06 05:21:50 ok Sep 06 05:22:18 "This status code is not specified in any RFCs, but is used by some HTTP proxies to signal a network connect timeout behind the proxy to a client in front of the proxy" Sep 06 05:22:25 probably not what youre looking for though Sep 06 05:22:43 desmin88, I found that. But how do I interpret that? What am I doing wrong? Sep 06 05:22:52 Searching didn't show much help Sep 06 05:22:59 why do people cry so much with reflection solutions... even android documentation suggest reflection to handle compatibility Sep 06 05:23:11 desmin88, The exact same code works flawlessly usually - every once in a while it fails. Sep 06 05:23:22 look at other google oauth implementations Sep 06 05:23:31 cliffreich: it depends Sep 06 05:24:33 usually its just that reflection is slower Sep 06 05:25:28 /can/ be slower Sep 06 05:28:47 oh Sep 06 05:29:23 yeah maybe a bit. some people overreact thou Sep 06 05:29:40 it's not flawless if it fails Sep 06 05:29:40 pfn pretty interesting http://www.infoworld.com/t/java-programming/scala-founder-language-due-fundamental-rethink-249845 Sep 06 05:29:49 it's just dumb luck that it works Sep 06 05:31:38 "This class was added in Android 4.0 (Ice Cream Sandwich). Use reflection to enable the response cache without impacting earlier releases:" Sep 06 05:31:45 android doc Sep 06 05:31:52 heh Sep 06 05:32:42 seen the same to handle handset custom stuff Sep 06 05:33:50 i thought Odersky's statements about the trends of fusion between OO + functional were interesting; he seemes to also think Swift borrowed a lot from Scala Sep 06 05:34:26 pretty cool stuff, i love these kinds of interviews when the language designers speak about what they are thinking :) Sep 06 05:35:10 fundamental rethink seems too strong of a term Sep 06 05:35:19 desmin I think what you linked wont help me, like how am I suppose to use that in a if stement, and second when I call my string it expects me to put an expression which I tried putting method(b) since boolean b but that doesnt work neither. This isn't as simple as you claim. Sep 06 05:35:52 string(b)* Sep 06 05:36:04 Odersky himself called it a fundamental rethink; although i'm not following close enough to know what exactly he had in mind beside things superficially mentioned here Sep 06 05:36:24 yo after this latest BNG4 update should I wipe cache or anything? My phones seems to lag now...... Sep 06 05:36:39 wrenny please read the topic :) Sep 06 05:37:03 not rooted Sep 06 05:37:48 sure, you can call modularity fundamental, but it's not so much a rethink Sep 06 05:38:25 g00s, see the screenshots of my updated acra collector? Sep 06 05:38:34 pfn no, link ? Sep 06 05:39:11 https://github.com/pfn/android_crash_reports/blob/master/README.md Sep 06 05:39:20 there are screenshot links there Sep 06 05:40:16 polymer is pretty neat Sep 06 05:40:31 frigging slow if you don't vulcanize, though Sep 06 05:40:58 yeah looks nice, i have to give polumer a try. i'm going through JS + d3 education, have to add that to the list Sep 06 05:41:33 a good analogy to polymer is mozilla xbl Sep 06 05:41:34 holy crap pfn you have a lot of tabs open :| Sep 06 05:41:45 that's not that many Sep 06 05:42:46 I also have 32gb of ram, so tabs aren't ever a concern Sep 06 05:43:07 * pfn zzz & Sep 06 05:47:47 Guys, i'm implementing service for messenger, i need a service that would always work in foreground and keep client online (despite of activity state). Thinking about how to organize start/stop of service more good-loking. Someone advices to organize it with bind/unbind (Bind to service with first and following starts from activity and unbind only when user wants to close messenger) But i think it is not the best solution. What do you think about it? Sep 06 05:48:29 for something like that, you would likely want to use start/stop service, not bind/unbind Sep 06 05:48:57 if you bind to the service from the activity, it will automatically unbind when the activity closes Sep 06 05:49:37 olologin == Ologn ? Sep 06 05:49:58 ah, nm Sep 06 05:54:36 JesusFreke: Ok, when i launch activity again and it tries to start service again (When it already running), i should immediately use something like: Sep 06 05:54:36 if (this.isRunning) return START_NOT_STICKY; Sep 06 05:54:36 ? Sep 06 05:55:16 in onStartCommand ofcourse Sep 06 05:55:44 olologin: only one instance of your service will ever be running. If you try to restart it, it will call onStartCommand on your already running service Sep 06 05:56:26 If you want the service to remain running, you'll want to return START_STICKY Sep 06 05:56:48 yeah, deciding whether to use start/stop, bind/unbind or both overlapping is a big decision Sep 06 05:57:17 gets even more interesting when you consider foreground status, wakelocks ;) Sep 06 05:57:31 bankai_jp rx 0.20.4 Sep 06 05:57:37 oh bankai_jp is in jp now ? Sep 06 05:58:05 So even without this if statement system never creates 2 instances of same service? Sep 06 05:58:20 correct Sep 06 05:58:31 there can never be 2 instances of the same service running simultaneously Sep 06 05:59:36 Hm, but with second startService i see in logcat that system calls onStartCommand again (While previous service instance still runs) Sep 06 06:00:15 maybe it's calling onStartCommand in the same instance Sep 06 06:00:22 Understood Sep 06 06:00:38 you can always Log.d("SERVICE", this) Sep 06 06:00:51 fron onStartCommand Sep 06 06:00:54 from* Sep 06 06:02:08 Problem because i run my tasks in new thread which starts in onStartCommand, so i need to move thread start to onCreate. Sep 06 06:02:51 well there you go then Sep 06 06:03:01 thanks guys Sep 06 06:04:08 no...my other names are like, Onlogn etc. Sep 06 06:04:31 ok... Sep 06 06:04:34 Wherever You Go, There You Are Sep 06 06:04:37 XD Sep 06 06:04:59 yeah, deciding whether to use start/stop, bind/unbind or both overlapping is a big decision <-- not really, I always go for both, seems to provide the most versatility with no visible downsides ;) Sep 06 06:05:30 s/always/the majority of time/ Sep 06 06:05:33 ravilov great, i'll just ask you when i get stuck then :) Sep 06 06:05:42 feel free :p Sep 06 06:06:33 i try not to use bind / unbind ... sometimes you can get away with simply querying a static in the Service Sep 06 06:07:10 i'll usually only use bind / unbind when i need to send commands that don't overlap with service start lifecycle Sep 06 06:07:30 (so long as you'll be asking about services and not getting out of jail after being busted for owning pot or something :p ) Sep 06 06:07:59 nah, i'm handicapped enough - that stuff would be the end of me :) Sep 06 06:08:01 I'm novice in android development, and for me it's not clear why sometimes peoples do all work in onCreate and leave onStart method empty :) Sep 06 06:08:19 usually i only see creation 1 time start stuff in onCreate Sep 06 06:08:32 onStartCommand is when ... you can get multiple commands :) Sep 06 06:08:52 olologin, because the two have a different purpose Sep 06 06:09:07 they are called at different points in the lifecycle Sep 06 06:09:23 I know about lifecycle Sep 06 06:10:23 well then Sep 06 06:12:18 Also about services: In my opinion word "service" means that it always unkillable, but in android, systems kills it every time, even when resources are sufficient, like 300mb ram free. Sep 06 06:12:23 Just saying Sep 06 06:12:49 With foreground feature ofcourse i recieve that behaviour Sep 06 06:13:00 so I have a question now, I have a OnMenuItemClickListener and I want to start an activity when the menu item is clicked, but for that I would need a reference to the activity, can I get that somehow from the MenuItem? Sep 06 06:13:00 but i think it should be that by default Sep 06 06:13:34 olologin, whether the system will kill it or not has not much to do with resources available, rather with the way it's started Sep 06 06:13:54 if it is started and tells the system it is to be permanent, the system will (or should) restart it if it gets killed Sep 06 06:14:55 olologin, there is quite some history behind this, something to do with people abusing services, starting them and leaving them even when unneeded, and thus hogging the entire system/device Sep 06 06:15:12 so I think it might have been the default but people proved to be irresponsible with it so the default got changed Sep 06 06:16:06 ravilov: Yes, maybe it makes sens in that case. Sep 06 06:48:06 yey https://groups.google.com/forum/#!topic/adt-dev/frugpmBwQt0 Sep 06 06:48:16 reported on 12/4/2013 Sep 06 06:48:31 xav says he'll look into it 12/5/2013 Sep 06 06:48:51 people still having problems with it today, in 2014 Sep 06 07:13:34 there is any letter to set double values like long an its ex: 2L Sep 06 07:16:22 what? Sep 06 07:17:37 there's a period Sep 06 07:55:36 I have two switch case stmts. One holds a label1+edittext1 and the other holds label2+edittext2.all those views are written programatically. And my xml file only holds LinearLayout,orientation=vertical. How can I make them to appear as label1 edittext1 and next line label2 edittext2 through code not xml? Sep 06 07:56:46 layout.setOrientation(LinearLayout.HORIZONTAL) makes all the views to come in one line Sep 06 07:57:05 I want them in two different lines Sep 06 07:59:56 I think I should be having two LinearLayouts calling one at a time as required Sep 06 08:02:18 Or a GridLayout Sep 06 08:02:26 if you want them aligned Sep 06 08:23:07 <_flip> what's the best way of handling a global state in an android app? Say for something like a LoggedIn state? Sep 06 08:27:16 A static class with setters and getters? Sep 06 08:28:19 _flip: create a class that extends Application and set it in the tag in the manifest and just like an use the android:name attribute. Sep 06 08:28:56 _flip: then you can put your state in there Sep 06 08:29:25 _flip: at any time you have a context call context.getApplicationContext() and cast it to your custom extended class Sep 06 08:31:02 <_flip> thanks Napalm|vacation Sep 06 08:31:05 np Sep 06 08:36:07 <_flip> also thanks eckesicle, that would be the standard way of doing it. I was just wondering if there was a more "android" way of doing things. Sep 06 08:36:43 <_flip> still trying to wrap my head around how android works with the contexts, activities and intents etc. Sep 06 08:42:54 I would not extend the Application class Sep 06 08:43:41 using the Application class is really only necessary if you want to handle broadcasts in it Sep 06 08:44:18 I would start with a static singleton and only if you need it transition to an Application-derived class. Sep 06 08:58:04 eckesicle: whats the downside in extending application class vs singelton in your opinion? :) Sep 06 09:32:50 why google suggest to create static class for ViewHolder if later suggest to allocate a new object? Or static or a new() call. Sep 06 09:36:17 new static Sep 06 09:38:11 what do u mean with new static? Sep 06 09:38:28 there are no static classes in java Sep 06 09:38:33 well at least in way you think Sep 06 09:38:49 you can have internal static class or external normal class Sep 06 09:39:13 the point is that class doesnt have direct access to outer class method Sep 06 09:39:25 as the normal internal class would Sep 06 09:39:51 so you instantiate "static" classes as normal Sep 06 09:40:52 ok. thanks @Ashiren Sep 06 10:01:20 I would have sworn there was a fuzzy date formatter somewhere in Android / support libs Sep 06 10:01:27 anyone remember any lib for that? Sep 06 10:01:43 e.g. "3 minutes ago" formatter Sep 06 10:04:42 Mavrik if there is can you let me know, I never thought to look and did some rather untidy switch stuff :( Sep 06 10:04:49 Mavrik: android.text.format.DateUtils? Sep 06 10:05:58 that has outputs like "3 mins ago" or "yesterday" Sep 06 10:06:24 with DateUtils.getRelativeDateTimeString() Sep 06 10:07:52 danijoo wicked... Sep 06 10:07:53 :) Sep 06 10:08:51 Hey, I need to make a child View of a ListView not display the being-clicked-on animation when it's clicked. How do I do that? setEnabled makes it be greyed out, which I also want, but it still flashes blue when clicked. Sep 06 10:09:09 ah, DateUtils yes Sep 06 10:09:17 but... of course... no Locale parameter Sep 06 10:09:19 so f00. Sep 06 10:09:38 threenuc: a static background instead of a selector Sep 06 10:09:47 or make it not clickable Sep 06 10:09:50 and we still don't have a reliable way to override app locale it seems Sep 06 10:10:04 Mavrik: yeah thats one thing that bothers me too.. Sep 06 10:10:54 danijoo: How do I change a view to static programatically? I tried setClickable (or something like that). It was still clickable :| Sep 06 10:10:57 It's just annoying as hell, since there's bunch of people here that don't have phones which support local language Sep 06 10:11:00 but the app is in local language Sep 06 10:11:12 so you get half translated crap :/ Sep 06 10:11:44 threenuc : what do you mean by setting a view "static"? Sep 06 10:11:48 also there are users that might want one app in another language.. Sep 06 10:11:53 rgr: he means not clickable. Sep 06 10:11:57 ah Sep 06 10:12:14 and as I said, just remove the selector Sep 06 10:12:22 sound right :) Sep 06 10:12:33 setEnabeled(false) should do the trick too i think Sep 06 10:13:11 if thats what he really meany by "static". Does he want it to "grey out" too? Or he could just replace the listener to do nothing. Sep 06 10:13:42 12:08 threenuc: Hey, I need to make a child View of a ListView not display the being-clicked-on animation when it's clicked. How do I do that? setEnabled makes it be greyed out, which I also want, but it still flashes blue when clicked. Sep 06 10:13:46 or rather set a member on the wrapepr class which tells the listener to do nothing and ignore the click. Sep 06 10:15:42 I need it to become greyed out (which setEnabled does just fine), then I need to make it so it doesn't display the click animation (the view flashing blue) when clicked. When clicked it displays a toast. Sep 06 10:20:11 blah yeah, that DateUtils isn't localizable at all Sep 06 10:20:53 Does ListView have a separate selector style for disabled elements? Sep 06 10:21:25 Mavrik: maybe you can override some method to to not use Locale.getDefault? Sep 06 10:21:39 nah, it doesn't work :/ Sep 06 10:21:43 due to this: http://stackoverflow.com/questions/6539195/force-android-dateutils-getrelativedatetimestring-to-ignore-the-device-locale Sep 06 10:21:46 I guess manually it is. Sep 06 10:23:01 i see Sep 06 10:23:22 would have been to easy to have a setLocale method... Sep 06 10:26:17 yes, that would make Android development boring or somethin :P Sep 06 10:39:19 In android studio, i got this "Exception raised during rendering: java.lang.System.arraycopy([CI[CII)V" when i tried to use the xml gui editor(drag and drop widgets one). How do i fix this? Sep 06 10:54:00 Does will be google fit API only for android L? Sep 06 10:56:41 HI Sep 06 11:46:26 SohamG: you dont. Its a bug. It will be fixed. Report the bug if its not already registered. Sep 06 11:54:40 rgr : A temporary solution is to set the API level there to 19 with verison 4.4.2.... Sep 06 11:56:29 Temporary solution is to not use AS until its out of beta :p Sep 06 11:57:36 Also, don't use drag and drop to build UX Sep 06 11:58:19 AS/Intellij are incredibly stable considering its "beta". Well IJ is. The only niggle is device dependant layouts. I have to tickle it all the time to get the build to pick up the new layouts. Sep 06 12:01:25 hi there guys, is there any way to make an adb server temporally unkillable? Sep 06 12:01:48 and on that subject it wont pick up the new smaller size layout!!!! aargh....its continuing to use an older now gone version. bah. Sep 06 12:03:20 android dev dev Sep 06 12:03:23 bam bam bam Sep 06 12:06:48 A menu in my action bar won't inflate... I have overridden onCreateOptionsMenu() and onOptionsItemSelected() in the activity... I have a debug message that prints in onOptionsItemSelected() so I know it's being called when I click the button... I just don't understand why the menu doesn't pop up. Am I doing something wrong? Here's the activity source: http://pastebin.com/Ma3NisRN Sep 06 12:09:40 HearWa: menu item not visible at all or just dont react to clicks? Sep 06 12:10:50 The menu isn't displaying. When I click the button I see my debug message in logcat. Would it help if I gave you the menu xml as well? Sep 06 12:10:58 you call the super onOptionsSelected first. Sep 06 12:11:05 ignore Sep 06 12:11:25 yes that would hep Sep 06 12:12:15 menu xml: http://pastebin.com/zpw9QMsc Sep 06 12:12:16 HearWa: your problem is your calling super in onOptionsItemSelected. You shouldnt you return false to say "you process" it afaik Sep 06 12:12:51 so "return false" and not return super.onOptionItem...() Sep 06 12:13:02 C-q on the function name. Sep 06 12:13:05 (javadoc) Sep 06 12:13:26 rgr: what are you talking Sep 06 12:13:33 he says the menu doesnt show up at all Sep 06 12:13:44 what as optionsitemselected to do with that Sep 06 12:14:10 thats another issue. Im just pointing out the onOptionsItemSelected is wrong too. Sep 06 12:14:59 HearWa: maybe your menu got pushed into the overflow menu because you dont have enough room? Sep 06 12:15:04 I've tried various combinations where I just return true, return false, nothing works Sep 06 12:15:07 doo you see 3 dots in the menu? Sep 06 12:15:31 also hes calling super.onCreateOptionsMenu(menu) at the end and not at the start before he inflates. MAYBE thats an issue too. Not sure. Sep 06 12:15:37 I see the menu items, when I click on them I don't see the menu, but onOptionsItemSelected() is being called Sep 06 12:15:59 you dont see what menu? Sep 06 12:16:06 rgr: that doesnt matter. the order only determines the order of the menu items from superclass to child (first inflated, shown on the left) Sep 06 12:16:07 Nope, I see the resource images I defined for the xml elements Sep 06 12:16:19 danijoo_: ah ok. Sep 06 12:16:30 so you are actually seeing it when you see the images.. Sep 06 12:16:46 Im not sure what he can and cant see anymore :) Sep 06 12:16:55 same here ^^' Sep 06 12:16:57 I'm developing on a note 3 so I have lots of retail space on the screen. This is just an example I'm trying to get working. Sep 06 12:17:12 HearWa: explain again. You do or you do NOT see your own menu? Sep 06 12:17:22 I see the images in the action bar. When I click on them I am expecting to see a menu. I am not seeing that menu. Sep 06 12:17:23 HearWa: so to clear this up. you are seeing all the icons, but what you want is seeing the text? Sep 06 12:17:33 Drop down menu... Sep 06 12:17:41 you have no drop down menu in the xml Sep 06 12:17:45 why are you edpecting to see a menu. You told us nothing about that. there is no drop down. Sep 06 12:17:50 soo.. how should you see one? Sep 06 12:17:56 +1 :) Sep 06 12:18:32 That's odd, why does my preview window show a menu then? Sep 06 12:18:47 because preview never looks like it should Sep 06 12:18:48 :) Sep 06 12:19:08 what you are doing in your xml is just throwing all the 6 items into the actionbar Sep 06 12:19:09 :( Sep 06 12:19:13 and thats what you are seing Sep 06 12:19:24 Sorry guys new to this Sep 06 12:19:34 Ahh. Sep 06 12:20:07 Well then, I feel silly. So question then... how would I go about displaying a menu if I click on those? Sep 06 12:20:26 HearWa: use the debugger too. Step through. No need to add log messages. Set a breakpoint. No code to change. Less risk of breaking things. Have fun. Sep 06 12:21:38 Will do. Sep 06 12:22:18 HearWa: for a drop down menu, you must wrap two menus together Sep 06 12:22:21 like this: http://pastebin.com/9x1chC2W Sep 06 12:22:48 you ahve an outer menu (which will be the actionbar), and there is an item, which wraps the menu that item should show on click Sep 06 12:23:15 ignore the bad intendation in the file :p Sep 06 12:25:27 danijoo_: Thank you! That worked. Sep 06 12:25:53 yw Sep 06 12:26:15 I guess I was expecting the previous window to behave like the visual studio designer with the presentation. Sep 06 12:26:22 preview* Sep 06 12:27:22 I dnot get why you would think that. There is clearly no sub menu in your code. Sep 06 12:30:40 rgr: thing is that the AS/Intellij preview seems to show aeverything like it is in the overflow menu Sep 06 12:30:50 that might confuse users without experience Sep 06 12:31:48 Yeah that's what it was. I should have paid more attention to the xml layout though... Sep 06 12:32:04 sure. I must admit I rarely use the preview now : only to check what attrs are available. Sep 06 12:32:10 hey everyone Sep 06 12:32:17 android beginner here Sep 06 12:32:42 how do i use restful apis in my app? Sep 06 12:33:05 theres that site Sep 06 12:33:14 where you can enter a question Sep 06 12:33:41 but whats really p*ssed me off is this : I have a layout for a nexus 4 and one for the 7. I have just spent the bones of half an hour wondering why the N4 layout wasnt showing on the N4. I invalidated caches . I restarted, I gradle cleaned. You rewrote the layout file. I rebuilt. I deleted the app from the phone first etc etc. Nothing worked. In the end I copied the Nexus7 layout file over the top of the N4 one and "tada" it FINALLY Sep 06 12:33:42 picks up the device specific layout. Very poor. Sep 06 12:33:43 and get answers. im pretty sure its in the first 10 results :) Sep 06 12:33:56 danijoo_: I tried but Sep 06 12:34:05 everything is very confusing Sep 06 12:34:28 ashemark: yes. You need to read the docs and do some work. There are oodles of tutorials with examples in google. Sep 06 12:34:38 The ask specific Qs here. Sep 06 12:34:54 rgr: sure, i read the api docs Sep 06 12:35:04 but where to get started with android Sep 06 12:35:05 android restful api give me 3 tutorials on first page Sep 06 12:35:08 API docs are for looking things up. Sep 06 12:35:17 read tutorials and StackOverflow examples. Sep 06 12:35:50 if you want it really easy use http://square.github.io/retrofit/ Sep 06 12:36:16 danijoo_: thanks a lot Sep 06 12:36:31 can you explain a couple of theoretical questions I have? Sep 06 12:36:41 maybe Sep 06 12:36:47 Like there are RESTful apis and there are some called SOAP Sep 06 12:36:50 ashemark: seriously, there are oodles of examples and free code. http://lmgtfy.com/?q=android+restful+example Sep 06 12:37:13 rgr: gotcha Sep 06 12:37:25 but just need some meta knowledge here Sep 06 12:37:27 ashemark: thats not on topic. Thats your own research. https://duckduckgo.com/?q=rest+vs+soap&t=debian Sep 06 12:37:57 rgr: sure Sep 06 12:37:59 its all in the google foo ;) Sep 06 12:38:05 :D Sep 06 12:38:37 thanks Sep 06 12:39:51 guys, I have a request. Could someone point me to a tutorial or something where I can learn to make a webservice or whatever to access online databases and stuff from an android device? I coudn't find anything android specific :( Sep 06 12:40:34 lol Sep 06 12:42:00 I need a Service running the background. It will make a notification and broadcast an intent with data. The notification has a pending intent that starts an Activity. If the Activity was already running, it will also receive the broadcast intent. Anyway! I basically want to start the service and forget about it. But for good measure, I'd also like to be able to stop it. Sep 06 12:42:59 luci1093: can you be a little more precise : whats a "web service or whatever"? Sep 06 12:43:35 I have two fragments - a grid view and a list view Sep 06 12:43:44 Certainly android talking to a database is well covered : often just through async rest calls Sep 06 12:43:46 I want to now make a nice widget that lets you switch between the fragments Sep 06 12:43:48 well, to be more precise I don't know how am I supposed to access a database stored on a server on the internet ... Sep 06 12:43:58 should I make another fragment that I put these two fragments in? Sep 06 12:44:01 Should I simply extend IntentService and add my stuff in onHandleIntent(), run startService() and eventually stopService()? If I understand it correctly, onHandleIntent() runs inits own thread, so this is nice. But how does stopping it work? Do I need my own boolean to check if I should break out and return onHandleIntent()? Sep 06 12:44:04 or should I make a view or something? Sep 06 12:44:32 its a big topic. You should probably read up on what a server is and how clients connect to an rdbms. The the android bit will come into Q... Sep 06 12:44:46 but async rest is one such way. Sep 06 12:44:59 What's the difference between a fragment and a view? When should I use one or other? Sep 06 12:45:42 luci1093: It doesn't usually work that way, unless it's your own database. For example you can open up a mysql port to the Internet, but that's ill-advised... most of the time if you need to communicate with a database you will be doing it though an API that has been made available... be it restful, soap, or something they scraped together... barring that you can write a web-scraper Sep 06 12:46:26 well yes... my problem is how exactly do I do that API to access the database :| Sep 06 12:46:55 Well that depends on what you need to connect to, and what they allow you to do, so specifics are needed Sep 06 12:47:09 For instance twitter and facebook both have an API Sep 06 12:48:23 well I pretty much need the general knowledge to making those APIs ... Sep 06 12:48:51 of course where there is an API already I'm going to use it... but what if I need to make one? :S Sep 06 12:48:58 You don't make them, you use them, if you are connecting to someone elses database as it seems Sep 06 12:49:03 JohnFlux: it can be tricky and often device dependent views are enough. A fragment allows you better ability to structure your app - tablet or not. The fragments are then accessed from the activity. Fragments should never inter communicate IMO : always back through the "mother" activity. That way you can plug functionality in and out depending on need, screen dimensions or whatever. I recently converted my first app to fragments and it Sep 06 12:49:03 just makes for a better structure too IMO. The fragments are then in charge of inflating their own views. I really recommend this book - a pdf can be found (no idea how legal) : http://www.amazon.com/Creating-Dynamic-UI-Android-Fragments/dp/1783283092 Sep 06 12:49:23 I'm an android noob but you should look into soap and restful interfaces. Sep 06 12:50:41 rgr: is that different from a view though? Sep 06 12:55:30 hello, anyone developed an app that "uses" stk? Sep 06 12:55:58 you really need to try it. Have a couple of different views then convert to frags and see. Its very hard to explain. Im noob enough not to be able too : but youre not alone. A brief google through stackoverflow shows many people saying "use fragments" with no realy reasn why. That book nails it IMO. Sep 06 12:57:08 Most you can emulate with views I agree. And the fragment gives you direct access to the Activity too which may sound minor but its quite nice ;) Sep 06 12:59:07 The first answer here addresses your Q : http://stackoverflow.com/questions/9827072/why-use-fragments Sep 06 13:29:42 rgr: is it fine to have fragments inside of fragments? Sep 06 13:32:35 Its just a "thing" like anything else. I havent done so but I see no reason why not. A brief google says YES you can in android 4.2.2 onwards. Sep 06 13:32:46 http://stackoverflow.com/questions/6847460/fragments-within-fragments Sep 06 13:32:53 4.2 Sep 06 13:35:26 just make sure to use the support-v4 Fragments Sep 06 13:35:30 or you'll have hell on earth. Sep 06 13:41:54 <_flip> So I have a MainActivity, this gets started when i launch my app. In MainActivity.onCreate() I check isUserLoggedIn = false then StartActivity(LoginActivity) Sep 06 13:42:07 <_flip> this sort of works, but I have problems with the back button functionality Sep 06 13:42:31 <_flip> what would be the recommended way of dealing with this? Sep 06 13:44:21 <_flip> I suppose the problem is that i don't destroy the MainActivity and so when i press the back button MainActivity.onCreate isn't called Sep 06 13:44:53 <_flip> would the best way be to simply override onBackPressed in the LoginActivity and have that terminate the app? Sep 06 13:45:14 <_flip> it still seems a bit crude... Sep 06 13:46:11 _flip, just finish() the main activity Sep 06 13:46:18 right after you call startActivity Sep 06 13:46:26 and it'll be removed from backstack giving you behaviour you want Sep 06 13:47:06 <_flip> is that recommended? right after successful login i go straight back to MainActivity Sep 06 13:48:52 why wouldn't it be recommended? Sep 06 13:49:25 you'll most likely have to refresh at least some state depending on login in the MainActivity, which makes your code significantly simpler Sep 06 13:50:40 <_flip> right, thanks. Sep 06 13:51:19 I have two fragments. Each fragment has an AsyncTask in them and use two different interfaces so the AsyncTask can send results back to the fragment. The AsyncTask is called in the onCreateView...the AsyncTask executes, but it also executes the AsyncTask in my other fragment which has not been created. How is this possible? Sep 06 13:52:24 when one asynctask in one fragment is executed, it executes the other one as well, in the other fragment Sep 06 13:52:38 and the other fragment hasn't even been created yet Sep 06 13:53:19 O.o Sep 06 13:53:31 sounds like you would get alot of complexity fixed if you'd use a message bus library :) Sep 06 13:55:35 Why are the two asynctasks being executed one after another the activity doesn't even create the second fragment which holds the other asynctask? Sep 06 13:55:56 because you execute it Sep 06 13:56:22 it would be wierd if it wouldnt - you said so yourself, you execute the second asynctask when the first completes Sep 06 13:56:32 how? The fragment that executes the second asynctask is NOT created when the first fragment executes its asynctask Sep 06 13:56:40 no i didnt Sep 06 13:56:48 pastebin the code of the first async task. Sep 06 13:56:56 ok hold on Sep 06 13:57:51 http://pastebin.com/RdYyf8YN Sep 06 13:58:25 em, there's something missing Sep 06 13:58:39 Fragment A is drawn on the Activity... ^^ that asynctask executes..then for some reason Fragment B's asynctask executes as well Sep 06 13:59:58 MartialLaw, it doesn't look like you pasted the full asynctask code. Sep 06 14:00:06 where's the onPostExecute_ Sep 06 14:00:07 ? Sep 06 14:00:41
