**** BEGIN LOGGING AT Thu Jul 09 10:11:52 2009 Jul 09 10:16:27 i'm trying to add a imagebutton to my widget. if added the imagebutton, set a source, made the layout settings... do i have to do some more for it to show up? Jul 09 11:04:02 hi all, wondered if anyone can help me with this: holder.statusbutton.setImageDrawable(getResources().getDrawable(R.drawable.unpaid_button)); Jul 09 11:04:45 getResources is saying cannot make a static ref to a non-static method Jul 09 11:13:46 i thinnk I need to add a new context, still trying to understand context Jul 09 11:24:25 johnnyzen: what type of object is holder? Jul 09 11:25:08 static class ViewHolder Jul 09 11:25:37 what's a viewholder? Jul 09 11:25:50 you can't have a static class Jul 09 11:26:21 you can have static methods but not a static class :) Jul 09 11:26:23 just a class to hold ref e.g: ImageButton infobutton; as per Romain Guys's tricks to optimise layouts Jul 09 11:27:04 Amorgos: taken from: http://code.google.com/events/io/sessions/TurboChargeUiAndroidFast.html Jul 09 11:27:35 in java, when ou get the error "cannot make a static ref to a non-static method".. it meeans that you are calling a method which is not static Jul 09 11:28:28 intersting, I still dont understand when to use static and non-static. when I start using static methods, I always end up making other methods static to stop that error message. Jul 09 11:28:49 so i end up with a whole class full of static methods. Jul 09 11:29:55 I'd recommend you take time to read a book on basic java. It'll make your android life much easier. This is key java stuff and you'll struggle with android if you're not familiar :( Jul 09 11:30:31 for example, within a static method, I need to call another method, but that method I am calling is non-static, so hence the error. Jul 09 11:31:20 yes, I should get my head around static and non static, - i did try to read about this, I will read again Jul 09 11:31:22 well yes, that's because a non-static method is called on an object, not a class. Jul 09 11:32:13 an object is an instance of a class Jul 09 11:32:28 AClass object = new AClass(); Jul 09 11:32:37 object.nonStaticMethod(); Jul 09 11:32:44 AClass.aStaticMethod(); Jul 09 11:33:25 a ha. Jul 09 11:34:07 so static uses the class directly and non-static uses the instance ? Jul 09 11:34:55 yes Jul 09 11:35:12 you create a static method for general things Jul 09 11:35:26 you create a non-static method for things only for that object Jul 09 11:35:31 i think Android is wrong way when AspectJ/AspectWerkz/GluonJ is used Jul 09 11:36:35 ok, thanks, I will try to understand this in my code :) Jul 09 11:41:58 But i'd DEFINETLY recommdend picking up a basic java book. It's impossible to code android without knowing it. It is java after all. Jul 09 11:45:47 Why is this channel full of so many people and so very very quiet!? Jul 09 11:53:21 .... no answer :) Jul 09 11:55:54 everyone is busy coding :) i'm trying to learn :) Jul 09 11:57:44 Out of interest johnny, what are you trying to code? :) Jul 09 12:01:18 why dont we have opensource 3g or LTE stack for telephony :p Jul 09 12:11:27 Amorgos: just a custom list with buttons :) Jul 09 12:12:39 vinzy: write one for gnu radio ;) Jul 09 12:16:34 anyone here asked by netdragoncompany.cp for app distribution to chinese market? Jul 09 12:17:07 mharkus: no, but what are they? Jul 09 12:18:50 http://ir.netdragon.us/ Jul 09 12:18:57 primarily working on online game development Jul 09 12:19:21 * Ge0rG was already called by chinese gold farmers... but nobody wanted my appz Jul 09 12:19:57 but they asked me to translate my apps to chinese and sell it via http://android.sj.91.com/ Jul 09 12:20:24 i got an email from some chinese too Jul 09 12:23:10 This is Whynonna writing from NetDragon Websoft Inc. (China). Jul 09 12:23:12 our company website: www.nd.com.cn, and the English website: http://ir.netdragon.us welcome you review it freely. Jul 09 12:23:26 Currently, we can only provide free service to translate and distribute free or trial versions. If you have other apps Jul 09 12:24:30 "This is Eva Zhao from Android Business Department of NetDragon Company" - this is what I got Jul 09 12:25:15 maybe diferent people because you have a paid app? Jul 09 12:25:38 I only have free apps Jul 09 12:25:47 dont china have android market? Jul 09 12:26:15 the certain carriers may not Jul 09 12:26:15 i think they are being blocked from accessing google sites? Jul 09 12:27:15 my big concern is that im going to get a flood of chinese emails Jul 09 12:27:20 and not be able to respond Jul 09 12:27:27 ive already gotten a few and my app is only in english Jul 09 12:27:31 blau: google-translate :D Jul 09 12:27:35 lol Jul 09 12:28:04 hi. System.getProperty("user.dir") returns null, is this expected behaviour or did i miss something? Jul 09 12:28:13 what kind of emails are you getting? or i suppose, you don't know seeing as ou can't understand them :) Jul 09 12:28:30 they look short Jul 09 12:28:37 lol Jul 09 12:28:58 ????LED???,??????!???! Jul 09 12:29:05 what app have you developed to make the chinese interested? Jul 09 12:30:18 the 2 i was contacted about were dg alert and dgaway Jul 09 12:30:29 a couple of widgets..fml widget and moon phase..both free Jul 09 12:30:52 what do the widgets do? Jul 09 12:30:57 i made a fml proof of concept Jul 09 12:32:28 i got this off the web.. "FML Widget is a widget that displays latest FMLs from FML website. Updates every hour. " Jul 09 12:32:32 the fml widget simply pulls fml items and displays it..the moon phase just displays the phase of the moon.. :) Jul 09 12:32:36 ok.. so what's an FML? :) lol Jul 09 12:32:37 yeah Jul 09 12:32:53 http://fmylife.com/ Jul 09 12:33:21 collection of people's F*** my life experiences.. Jul 09 12:33:25 ah ok Jul 09 12:33:54 lol, that's not a straightforward translation to chinese is it ? :D Jul 09 12:35:13 maybe they will just need to translate the app's strings.xml, not the data being pulled from FML site Jul 09 12:35:56 yeah, but the data from the FML site is kinda the important bit though! No point in translating the app if the content is in english Jul 09 12:36:22 yeah Jul 09 12:37:05 Thats what i like about android dev though, it almost forces your app to become very easily translatable Jul 09 12:40:04 so mharkis, out of interest, how much interest have you had up to now? Jul 09 12:40:11 mharkus Jul 09 12:40:41 in the application i mean, how many people are using it? Jul 09 12:51:41 is it allowed to add subfolders to res/ ? Jul 09 12:53:30 tarzan: no i dont think you are Jul 09 12:53:38 it's pretty strict with that stuff Jul 09 12:53:59 it's annoying not being able to add subfolders to the drawable folder Jul 09 12:54:44 if i want to deliever multiple jars with my application (dexed osgi bundles), where should i put these to be deployed? Jul 09 12:55:24 what's a "dexed osgi bundle" jar? Jul 09 12:57:50 its basically normal jar containing classes which are loaded at runtime by the osgi environment i am using. currently im manually pushing them with adb to the sdcard Jul 09 12:58:21 dexed = using dx / aapt to add classes.dex to the jar Jul 09 12:59:03 but it would be nicer if i had a folder in my eclipse project which is pushed to the emulator when the application is deployed Jul 09 12:59:11 well, if you're android project is referencing them in eclipse, it will bundle them with the rest of your code it will convert the java bytecode to dalvik Jul 09 12:59:32 that's the point, there are no references Jul 09 12:59:46 at least not to all of the jars Jul 09 12:59:57 well, can't you make them references? Jul 09 13:01:10 i don't want to, is there no other way to do this? Jul 09 13:02:02 have you tried putting them in the assets folder of your project? Jul 09 13:02:25 so maybe you could manually do what you need from code and access them from there Jul 09 13:05:04 will the files in the assests folder be deployed somewhere to the file system where i can read them or is AssetManager the only way to get the files? Jul 09 13:09:52 i dont know if the AssetManager is the only way to access the files Jul 09 13:10:11 ok thanks, i will continue reading the docs and googling :) Jul 09 13:11:11 np Jul 09 13:16:29 How to place two radio's next to each other ... I tried relative layout but radios need radiogroup :( Jul 09 13:18:09 radio buttons are sorely neglected on mobile platforms Jul 09 13:19:18 ic ... tnx Jul 09 13:20:10 how can I make a list like the songs list on the music player, or the prefs list, or any list that has icons at the right of the items Jul 09 13:20:48 Skail, download the Apidemos example project from google, and go from there Jul 09 13:20:52 if the text is "wrap_content" the icon doesn't go at the right, but if the label is fill_parent, it pushes the icon off the edge Jul 09 13:21:39 the docs say this is because the text doesn't know how much space the icon is going to need ahead of time, but that gives no hint as to the solution Jul 09 13:22:50 I can't realy visualise what you're trying to do Jul 09 13:23:09 have you considered another Layout type? Jul 09 13:23:32 Amorgos: think of the preferences lists. there is some text, with often an icon or checkbox at the right Jul 09 13:23:47 I've been trying all the layouts, I just don't see how to get the right result Jul 09 13:24:13 Table layout? Jul 09 13:24:29 i've done kinda the same thing. text on one side and icons on the right Jul 09 13:24:47 you should be able to set the android:layout_width of the image. i think that might be the right direction for you. Jul 09 13:25:27 setting the width of the image is no help, because the system parses the text label first, and uses up all the space if it's fill_parent Jul 09 13:26:00 dont use fill_parent. the very definition of that option is "use all space" Jul 09 13:26:23 for each item i your list, you could have a tablelayout inside them. that'll work Jul 09 13:26:23 kaay: yeah, obviously, but then how else does one get the text to fill the space? Jul 09 13:27:00 you can use wrap_content and android:layout_weight Jul 09 13:28:40 oh lovely.... wrap_content is only wrap_content with no weight.... Jul 09 13:28:52 kaay: that seems to do exactly what I need Jul 09 13:28:55 thanks! Jul 09 13:30:03 * Skail mumbles something about the docs not having mentioned this special little behaviour :) Jul 09 13:30:30 there's a lot lacking in the docs :/ Jul 09 13:31:34 hi. Jul 09 13:31:59 most docs do "leave em wanting more" :) Jul 09 13:32:32 I'd like to use some non-sdk functions, (for personal use, not for sale, so i dont care that its not API stuff). how do I do that ? Jul 09 13:32:41 android docs are fantastic compared to iphone :) Jul 09 13:32:48 to be more specific, I want to use bluetooth related functions. Jul 09 13:33:50 unwesen: fantastic compared to the docs for a LOT of other things, really. We don't really have TOO much cause for complaint. Jul 09 13:34:15 nope, that's what I'm saying. iPhone just sticks out like a sore thumb Jul 09 13:34:27 and when the docs don't tell you what you need to know, you can read the source Jul 09 13:34:47 is the iphone easy to develop with (apart from shitty docs that is) ? Jul 09 13:34:56 kind of Jul 09 13:35:21 it's fairly easy if you stick to what the examples do, or if you start everything from scratch and bypass the SDK as much as possible. Jul 09 13:35:24 uh Jul 09 13:35:26 objective c Jul 09 13:35:30 * AakashPatel barfs Jul 09 13:35:39 twisting the SDK into something it's not designed for isn't a source of joy, though Jul 09 13:35:48 android's APIs are a lot more flexible in comparison Jul 09 13:36:01 syntactically and aesthetically, I'd prefer objective C over C++ any day Jul 09 13:36:05 and yes, objective-c ain't pretty, but it's not the worst part by far. Jul 09 13:36:12 objective c != c++ Jul 09 13:36:20 very different things Jul 09 13:36:54 both programming languages... :) Jul 09 13:37:06 :D Jul 09 13:37:07 i tried objective c Jul 09 13:37:11 it made no sense hha Jul 09 13:37:11 I'll grant you that Jul 09 13:38:45 eh, I can't say I like objective-c, but I don't like perl either, and can use it. Jul 09 13:39:31 you get things done Jul 09 13:40:25 someone can help with this -> http://www.anddev.org/viewtopic.php?p=24125#24125 ? Jul 09 13:41:46 patrick: have you looked in logcat for a stacktrace? Jul 09 13:42:04 no Jul 09 13:42:12 I'll do it Jul 09 13:42:37 look in Logcat first. then irc/forums ;-) Jul 09 13:43:04 patrick91: move setContentView before findViewById ? The stack trace would help Jul 09 13:43:24 ok Jul 09 13:43:34 setContentView(R.layout.view_odl); .. where is view_old? Jul 09 13:43:38 odl even Jul 09 13:44:03 good point :) Jul 09 13:44:03 it's not in that layout Jul 09 13:44:23 R.layout.view_odl is the layout Jul 09 13:44:51 but the top level LinearLayout has no id called view_odl Jul 09 13:45:57 unwesen: patrick91: move setContentView before findViewById ? The stack trace would help <- It works thanks :D Jul 09 13:46:08 yw :) Jul 09 13:46:37 Amorgos: but the top level LinearLayout has no id called view_odl <- I don't need the id Jul 09 13:47:05 ah yes of course Jul 09 13:47:55 and setContentView inflates the view, so you wouldn't have found the textview before it was inflated. probably causing the error Jul 09 13:50:04 do applications need special permissions to access files stored on the sd card? Jul 09 13:50:53 do you get a permission exception in logcat when you try? Jul 09 13:52:50 tarzan: not generally, no Jul 09 13:53:56 Amorgos: no Jul 09 13:54:03 unwesen: thanks, i thought so Jul 09 14:02:08 <_Roman> I have a string stored in the strings.xml file. How can I go about getting the text out of this string within my code? Jul 09 14:02:34 getSTring(R.strings.my_sting_name); Jul 09 14:03:59 <_Roman> Amorgos: eclipse wont let me call getString(). It is undefined. What is it a method of? Jul 09 14:04:25 Context Jul 09 14:05:30 <_Roman> How do I go about calling it? my method does not have a context object passed to it (nor can it). Can I just create a new Context object? will that work? Jul 09 14:06:13 no. you'll have to pass a context object to it. why can't you pass a parameter to your method? Jul 09 14:06:17 <_Roman> no apparently not, you can not instantiate Context directly. Jul 09 14:07:13 <_Roman> I am implenting a SQLiteOpenHelper subclass, I need to get the string in onCreate(). Jul 09 14:07:44 <_Roman> Actuially I have just realised that the Context is passed in on the constructor, so I can just store a private reference to it in my object Jul 09 14:08:13 yeah, so you can just make the context a parameter and get it from there Jul 09 14:08:44 <_Roman> just make the context a parameter?? what do you mean by that? Jul 09 14:08:55 <_Roman> instance variable? Jul 09 14:09:03 i mean the Context an instance variable yes :) Jul 09 14:09:23 _Roman: What class are you trying to do this in? what does it inherit? if it's any sort of activity then "this" is a context instance Jul 09 14:09:36 <_Roman> ok, cool. Just a little bit new to java, so just want to make sure that I do not misunderstand things. Jul 09 14:11:10 <_Roman> I am inheriting from the SQLiteOpenHelper class. I want to store my database creation statements outside of the class to keep things neat and tidy, so I thought I would use strings.xml to store the statements for use in the onCreate() method. Jul 09 14:12:20 well then you'll need to pass a context parameter to your SQLiteOpenHelper subclass from the activity that is using it Jul 09 14:12:24 Roman: there's a good example of that in Professional Android Development by Wrox. I was doing the same thing about an hour ago :) Jul 09 14:14:21 <_Roman> Amorgos: I will buy that now. btw. is it just me or are the official docs on developer.android.com not that great? Jul 09 14:15:43 i think the docs are alright. theres always a few things missing. if you do the tutorial and exercises i think you'll have a decent understanding of the fundamentals. Jul 09 14:16:05 <_Roman> thanks for all your help. Jul 09 14:16:12 they're 80% ok atm. better than 95% of frameworks :) Jul 09 14:16:23 doc_savage, great idea last night :) Jul 09 14:16:37 titefuzz: it worked? :) Jul 09 14:16:44 yes but now i have another problem... Jul 09 14:17:04 now if i do setcontentview... or create an activity and use startactivity() all i get is a blank screen Jul 09 14:18:14 but yeh, main program should always extend activity Jul 09 14:18:21 hmm, do you get a normal view on the first call to it? what's in the XML? Jul 09 14:18:42 theres two different layouts i have tried Jul 09 14:18:53 one is a linearlayout with a listview and a button Jul 09 14:19:22 titefuzz: I think you're ok to use a ListActivity as the main, but ListActivity *requires* that you have a listview within, so when you changed to another layout, it got upset Jul 09 14:19:39 yeah Jul 09 14:19:44 are these the same XML files you were using before when it was ListActivity (and they worked)? Jul 09 14:19:50 yes Jul 09 14:19:57 hmmm Jul 09 14:20:00 * doc_savage scratches head Jul 09 14:20:02 well, one is the same, and one is a new one Jul 09 14:20:32 i dont really see anything in the log that throws off a red flag Jul 09 14:21:47 so in onCreate your calling setContentView, and nothing is displaying... can you post the XML pastebin? Jul 09 14:22:14 no, the main menu displays fine Jul 09 14:22:24 but when i try to call setcontentview to change the layout Jul 09 14:22:37 in a button click event Jul 09 14:22:46 it changes to a blank screen Jul 09 14:23:28 http://pastebin.com/m21f6494f Jul 09 14:24:17 and that worked before (displayed ok)? Jul 09 14:24:42 yep Jul 09 14:24:45 im wondering Jul 09 14:26:12 I'm not 100% on the changing views mid-way through, would it not be better to have 2 activities? So when they press "add task" on the main menu, it spawns a new activity to add the task, then returns to the original? Jul 09 14:27:04 well thats what i tried for add task but i still got a blank screen, but i think i may have fixed it, testing it now Jul 09 14:27:14 nope :( Jul 09 14:27:15 ah ok :) Jul 09 14:27:47 let me whack that XML into one of my projects so we can see if it's the XML or something else going screwy Jul 09 14:28:12 well Jul 09 14:28:15 i have one other idea Jul 09 14:29:54 btw, has anyone had there emulator freeze before loading Jul 09 14:30:08 and the log has a few lines with type qemud Jul 09 14:31:07 so, i ave added both a constructor and the oncreate method to my addtask activity and used setcontentview but still blank Jul 09 14:31:44 so... user clicks menu to add task, and you call setContentView again to change the layout to that one, and that's where it goes blank? Jul 09 14:31:51 the first view your using works fine? Jul 09 14:32:27 yeah Jul 09 14:33:16 lol omg Jul 09 14:33:35 sry saw something funny on the highway Jul 09 14:34:29 ooooo Jul 09 14:34:33 lol I got visions of you then, driving along with a laptop balanced on the dash Jul 09 14:34:54 lol nah, im looking out the window of my office theres a highway right out here hehe Jul 09 14:35:14 some dude in a motorized wheel chair holding up traffic in the right lane Jul 09 14:35:15 classic Jul 09 14:35:21 haha quality Jul 09 14:35:33 ok Jul 09 14:36:12 now i get an unable to instantiate activity error... Jul 09 14:36:29 I'm not sure on the workings of setContentView, and whether it should be called twice, it says "This view is placed directly into the activity's view hierarchy." so I don't know whether it properly replaces the current view Jul 09 14:36:29 i guess my activity should be a seperate class Jul 09 14:37:02 that's the route I'd take, create a new activity class, get it to setContentView the new view, and just start that activity from the first Jul 09 14:44:32 *crosses fingers* Jul 09 14:45:43 :( Jul 09 14:45:48 uh oh Jul 09 14:46:16 still blank? Jul 09 14:47:12 unable to instantiate class error, wondering if i missing a method thats required to be overridden Jul 09 14:48:14 you're starting the new activity with an intent? and have added the new class to androidmanifest.xml? Jul 09 14:48:23 yeah Jul 09 14:49:05 super.onCreate(savedInstanceState); Jul 09 14:49:05 setContentView(R.layout.addtask); Jul 09 14:49:13 thats my oncreate method of my addtask class Jul 09 14:49:37 it's public, returns void, the class extends activity, you have activity imported for that class? Jul 09 14:49:40 Why is the market not installed on emulator? Jul 09 14:49:52 Intent i = new Intent(TaskManager.this,AddTask.class); Jul 09 14:49:52 startActivity(i); Jul 09 14:50:27 do i have to call finish() on the main activity? Jul 09 14:50:50 you shouldn't, unless you dont want to return to it Jul 09 14:51:01 ok Jul 09 14:51:30 when I do it, I would use Intent i = new Intent(this, AddTask.class); Jul 09 14:51:37 but i'm pretty sure that's the same as what you're doing anyway Jul 09 14:52:38 are there any other clues in logcat? double check the androidmanifest entry is right, that the new activity is a child of the application etc. Jul 09 14:52:59 nm : just read http://www.anddev.org/viewtopic.php?p=15311 ... this sucks :( Jul 09 14:53:54 logcat just says null pointer exception Jul 09 14:54:08 on what line, what's that line doing? Jul 09 14:54:33 trying to load the activity Jul 09 14:54:35 ngnp: what do you need it in the emulator for? Jul 09 14:55:07 titefuzz: specifically look at the "objects" on that line, one of them won't have been instantiated properly Jul 09 14:56:33 doc_savage: first thought was for testing my app stack (stupid thought :), other was playing games for my daughter and last was reverse enginering some apps :) Jul 09 14:56:34 working :))) Jul 09 14:56:50 had to remove the constructor Jul 09 14:56:59 titefuzz: nice :) and not blank? Jul 09 14:57:05 not blank :) Jul 09 14:57:17 sweet - get there in the end Jul 09 14:57:30 Hi guys, just a little question is there an easy way to correct this ugly thing while using a high screen resolution : http://img102.imageshack.us/i/screenr.png/ ? Jul 09 14:58:16 ngnp: ah, well if you have a phone, you should be able to swipe the APKs off that to install into the emulator (for games/apps, not the market) Jul 09 14:58:33 whats ugly abotu that Jul 09 14:58:57 doc_savage: you're right :(|) Jul 09 14:59:03 * ngnp bangs head ;) Jul 09 14:59:03 its not full screen blau-mikeDG Jul 09 14:59:04 the space betweens icons Jul 09 14:59:24 oh.. Jul 09 14:59:28 how do you have a high resolution? Jul 09 14:59:38 louis: you could modify Launcher Jul 09 15:00:22 Launcher ? Jul 09 15:00:30 I was thinking launcher was the "slider" Jul 09 15:00:45 louis: Launcher is the name of the Home app in the source Jul 09 15:00:51 okay Jul 09 15:01:05 thx i'll check this Jul 09 15:05:37 this should have been user configurable... Jul 09 15:06:16 feel free to contribute a patch Jul 09 15:11:15 lol Jul 09 15:11:26 how do you have a high resolution? Jul 09 15:11:49 the end user should really never be seeing high res launcher Jul 09 15:12:25 its not the question Jul 09 15:12:50 was thinking about Archos Android tablet Jul 09 15:13:20 well they can modify the os themselves Jul 09 15:13:25 and contribute the changes to the main Jul 09 15:13:59 hi Jul 09 15:14:05 well... Jul 09 15:14:13 i'll try to make it myself. Jul 09 15:14:22 but not today XD Jul 09 15:14:25 see you later :) Jul 09 15:18:36 i'd like to install libspeech.so in my htc magic (htc mytouch) to use VoiceSearch. anyone knows how to install?? Jul 09 15:19:12 mount your /system partition as read only, toss the so in there if you have room Jul 09 15:19:32 alternately, you can use System.load("libspeech") if you include it in your app and have it extracted to the libs dir Jul 09 15:24:24 I don't have root. Can I load libspeech with System.load(libspeech.so) ? Jul 09 15:25:40 yes Jul 09 15:25:55 System.load will load it for you for your app's instance Jul 09 15:26:25 on donut (iirc) when you put your app in /lib it becomes accessable for other apps as well, as long as they have appropriate permissions Jul 09 15:26:34 but I'm not really clear on that, do your own investigation there. Jul 09 15:27:02 I try it, thank u Jul 09 15:28:36 but yeah, you can absolutely do System.load. Jul 09 15:28:41 it's how copilot works : ) Jul 09 15:28:48 or is it loadLibrary? Jul 09 15:28:51 heck I forget now ._. Jul 09 15:29:05 LoadLibrary Jul 09 15:29:49 * doc_savage has just found out that android doesn't like managing null cursors Jul 09 15:35:23 vol_: the problems is, how to install libspeech.so in /system/lib in a handset without root ?? Jul 09 15:36:40 oh. You can't. Jul 09 15:37:41 :( Jul 09 16:06:07 2009-07-09 11:06:05 - HelloActivity] Unknown error: SDK is not loaded yet Jul 09 16:06:33 i am stucked with the error Jul 09 16:07:04 anybody know the solutions Jul 09 16:07:05 then you shouldn't call yourself a guru ^_^ Jul 09 16:07:18 that error happens when the sdk isn't totally loaded when your project is Jul 09 16:07:24 if you wait a few seconds it should resolve itself Jul 09 16:07:36 check the path in your settings to make sure that you have the right path Jul 09 16:07:41 try closing/reopening the project Jul 09 16:07:53 i wait about 1 hour Jul 09 16:08:54 if you're looking at the text log it won't clear itself Jul 09 16:09:03 do you get errors trying to compile because of this? Jul 09 16:09:33 the progress is 60% always Jul 09 16:09:41 yes when I compile Jul 09 16:09:59 try setting up the sdk from beginning again ... Jul 09 16:10:40 ok Jul 09 16:38:22 anybody around? Jul 09 16:50:41 What's the proper way to remove an overlay item from the map? Say I have 4 overlay items (map markers) on a map and I go to delete one, it shrinks the size of the ArrayList but all the other markers keep their index which causes an OutOfBoundsException when I try to click on the latest one added or when I remove another one. Are overlay items not meant to be removed? Jul 09 16:52:48 when you do remove from an arraylist, i thought it dynamically resize it no? Jul 09 16:53:27 i am pretty sure that's how it's suppose to be Jul 09 16:53:59 nm u meant the items Jul 09 16:54:09 phreak: ummm remove and do populate again Jul 09 16:56:15 chouman82, that worked great, however when there is only one left it throws an out of bounds exception, should I just do a check if there's one left and instead delete the entire overlay to combat this issue? Jul 09 17:04:32 like when there is one left and u r trying to remove the last one? Jul 09 17:04:51 yea haven't tried to remove opverlayItems Jul 09 17:05:02 i guess taht could be one work around Jul 09 17:05:17 it seems sometimes removing a point works sometimes it doesn't. when it crashes it gives me this: IndexOutOfBoundsException: Invalid location 3, size is 3 Jul 09 17:07:12 is it the index that you are trying to remove is wrong? Jul 09 17:07:31 maybe u want location -1 ? Jul 09 17:07:35 just a thought Jul 09 17:11:49 I'm not sure, it removes the right one when I click on the marker I want removed so that's not an issue, it's the ArrayList that keeps screwing up. If I remove them in order 0, 1,2,3 I only get the OutOfBoundsException when I try to remove 3, if I remove 2 first and then try to remove 1 I get an OutOfBoundsException on that one Jul 09 17:11:49 I have a TabHost, with each tab linked to an activity. I want an activity to be able to start a new activity, but have the new activity also contained in the TabHost. right now, the new activity goes fullscreen. Jul 09 17:14:17 phreak: well yes, that's normal Jul 09 17:14:36 phreak: if you have an ArrayList with 4 elements, and remove any element, then the array list has only 3 left Jul 09 17:14:42 therefore the index 3 does not exist anymore Jul 09 17:15:02 so I guess I need to prevent the list from shrinking when an index is removed? Jul 09 17:15:12 no you cannot Jul 09 17:15:21 either don't use an ArrayList Jul 09 17:15:28 or don't store the index of each marker Jul 09 17:15:44 you can call remove(Object) on an ArrayList btw Jul 09 17:16:09 well I think the ItemizedOverlay class stores the index, so you can use the onTap method, which is what I'm using to display a toast, which is why I liked the index scheme Jul 09 17:16:41 is there another type of list I could use that wouldn't shrink? Jul 09 17:16:58 it's called an array Jul 09 17:17:44 okay, I'll look into using an array then Jul 09 17:17:49 thanks for the help Jul 09 17:25:27 Does anyone know about swapping out what activities are associated with a tab in a TabHost? Jul 09 17:26:55 romainguy, how exactly would I go about implementing it as an array? Jul 09 17:27:26 as of right now, the arraylist stores an object, can you do with with arrays? Jul 09 17:30:08 yes, you can store objects in an array Jul 09 17:31:12 okay I've defined the new array like so: OverlayItem[] mOverlays; and I know I can add them like so: mOverlays[0] = overlay Jul 09 17:31:36 so now I would have to rewrite the addOverlay method to add a new overlay to the end of the array, correct? Jul 09 17:33:40 and I could do that using mOverlays.length as the index right, because that will return the size of the index and the index starts at 0 so it should always be the end index Jul 09 17:36:14 when building layouts, what do you guys usually use? (linear?,relative?,table?,absolute?) Jul 09 17:38:06 relative or linear Jul 09 17:38:11 absolute should really be your last choice Jul 09 17:38:26 only if it really, absolutely, has to be 10px off from the top left. Jul 09 17:38:37 otherwise, when devices come out with different resolutions your app looks stupid Jul 09 17:38:49 (or for a sizable minority of poorly made ones, when the user rotates the screen) Jul 09 17:39:26 ic Jul 09 17:40:38 I have had some trouble using relative so am using a table layout for my current application. I am worried about different hardware/screen resolutions causing my app to look funny or distorted on some devices. Jul 09 17:44:37 use whatever you think is necessary, just remember that things might be more brittle than you think. Jul 09 17:45:28 If I want to have an xml file to populate a view, is the best place for the xml file in assets? Jul 09 17:45:51 probably Jul 09 17:46:00 or res/raw Jul 09 17:46:11 res/raw lets you have variations based on resolution, locale, etc. Jul 09 17:48:10 argh, I mixed up res with assets Jul 09 17:48:17 what romainguy said Jul 09 17:48:26 Does SimpleExpandableListAdapter allow you to map to non-Strings? Jul 09 17:48:54 it looks like it does since it's generic, but i keep getting a class cast exception in bindView whenever I try to use a custom type Jul 09 17:49:30 thanks Jul 09 17:49:32 SimpleListExpander.java:249 -- v.setText((String)data.get(from[i])) Jul 09 17:50:15 should that be v.setText(data.get(from[i]).toString()) instead? Jul 09 17:51:39 oops, that's SimpleExpandableListAdapter.java: 249 Jul 09 18:16:27 hi all I am slowing getting my head around basic static/non-static and context, still having a little difficulty working out how to do certain things, for example: infoDialog = new AlertDialog.Builder(this).create(); - "this" needs changing, as getting a error. Jul 09 18:16:50 what's the best way to trace cursors that have umm been left open by shoddy coding and are causing exceptions when the app closes? Jul 09 18:17:17 johnnyzen: this code is in an inner class? Jul 09 18:18:20 hi romainguy: i am using your tricks for reusing layouts from the google video, so its within a onclick handler, within your getView trick (EfficientAdapter) Jul 09 18:19:26 but when you used static classes, etc, it has got me a bit confused, Jul 09 18:19:31 romainguy: filed the above SimpleExpandableListAdapter issue as http://code.google.com/p/android/issues/detail?id=3218 Jul 09 18:20:54 I have got my layout working, reclycing views - which is EXCELLENT btw :) Jul 09 18:21:25 johnnyzen_: from an inner class instance you can refer to the outer class instance by using TheOuterClass.this instead of this Jul 09 18:21:32 it doesn't work with static inner classes Jul 09 18:22:23 a ha. yes i read about this :) but didnt quite understand how to fix. :) thanks Jul 09 18:23:10 romainguy_: I've successfully switched from an ArrayList to an Array and it works when I add one item setting a fixed size for the array, but how can I make the array dynamic so I can add more than one item? Jul 09 18:24:24 romainguy: so in your example, the outer class would be - public class Testing extends ListActivity, but Testing.this is stating out of scope., I did think I tried this earlier (been trying to work out for hours) Jul 09 18:27:05 romainguy: sorry the exact message is: No enclosing instance of the type Testing is accessible in scope Jul 09 18:27:45 is your inner class static? Jul 09 18:29:03 "private static class EfficientAdapter extends BaseAdapter" - yes Jul 09 18:29:39 "romainguy_: it doesn't work with static inner classes" Jul 09 18:29:43
