**** BEGIN LOGGING AT Sun Aug 11 02:59:58 2013 Aug 11 02:59:59 using raw units would be hard to communicate with users. but as a way of faking tag removal it potentially could work. probably not in the car though and that might be a more common use case than usb debugging Aug 11 03:00:15 yeah Aug 11 03:00:25 also there's no way to scan for tags anyways Aug 11 03:00:36 and I'd like to have it at least check to make sure it's not still there Aug 11 03:00:48 yeah Aug 11 03:01:04 otherwise I could just poll Aug 11 03:07:18 Hello all. Aug 11 03:07:27 hello Aug 11 03:07:43 I am going through the Android dev tutorial and am getting the following error when trying to add an actionbar. This is from my Manufiest file. The code is " android:minSdkVersion="11" Aug 11 03:07:43 android:targetSdkVersion="17" /> Aug 11 03:07:43 ' Aug 11 03:08:00 It says not-well formed Aug 11 03:08:24 Eype Aug 11 03:08:25 error: Error parsing XML: not well-formed (invalid token) AndroidManifest.xml /MyFirstApp/bin line 7 Android AAPT Problem Aug 11 03:09:05 Could you use pastebin please? I can't read that in an IRC window and you're spamming up the chat. Aug 11 03:09:14 Yes, sorry Aug 11 03:09:53 j0b0x: please paste the whole xml file Aug 11 03:10:17 yes, that too Aug 11 03:10:54 Yes - here it is http://pastebin.com/Frs0FrVx Aug 11 03:11:01 Line #8 Aug 11 03:11:30 I am going through the following tutorial - https://developer.android.com/training/basics/actionbar/setting-up.html Aug 11 03:11:38 huh Aug 11 03:11:42 try retyping it Aug 11 03:11:56 like not copying and pasting, but typing it out again Aug 11 03:12:04 perhaps you somehow accidentally put in a control character and it doesn't like that Aug 11 03:12:10 I see. Will do Aug 11 03:12:23 that's the only thing i can think of Aug 11 03:12:36 Also, how can I check what version of Android I am supporting? Aug 11 03:12:54 that i have no clue Aug 11 03:12:59 i'm sure there's a chart somewhere Aug 11 03:13:02 Ok Aug 11 03:13:05 Thanks tpw_rules Aug 11 03:13:32 11 is honeycomb 3.0. if you don't need to support gingerbread, then i'd recommend just going all the way to 15 (4.0.3) Aug 11 03:13:50 there are very few honeycomb devices still out there, and honeycomb was kind of a mess and not really worth testing against Aug 11 03:14:04 i have a pre-honeycomb device :D Aug 11 03:14:05 j0b0x: http://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels Aug 11 03:14:33 also, for seeing what versions are in use: http://developer.android.com/about/dashboards/index.html Aug 11 03:16:24 I've also heard that supporting anything more than 4.0+ is mainly interesting if you're making a free app. Aug 11 03:16:42 that's scary that 1/3 of all devices are running an os two and a half years old Aug 11 03:17:28 only 40% are running an up-to-date version Aug 11 03:17:48 those would be devices that doesn't support the newest versions. Not everyone buy new phones every year ;) Aug 11 03:18:13 Hello everyone. Does anyone have experience working with the networking code? Specifically, if you are up to it, there is an issue with ARP reply packets being sent with 14 bytes, instead of the full 28 bytes. It is causing malformed packets to show up on the network. Aug 11 03:18:48 "Sender IP address", "Target MAC address", and "Target IP address" are missing. Aug 11 03:18:53 Thorbear: my five year old iphone can support the latest version Aug 11 03:19:01 same with my ipad Aug 11 03:19:26 but an android carrier can just be like "lol you suck" and you can't upgrade your device Aug 11 03:19:34 I can't be sure, but it appears as if it is related to code between lines 10-7 and 127, here: https://github.com/swatspyder/android_frameworks_base/blob/cm-10.1/core/java/android/net/arp/ArpPeer.java Aug 11 03:20:19 107* Aug 11 03:24:21 Hmm not sure what I did but I fixed it with the same paste bin code. I think there might have been a hidden character from copying pasting Aug 11 03:24:22 Thanks again all Aug 11 03:27:47 j0b0x: yeah, i think that's what happened Aug 11 03:45:52 _wli, for the love of scrollback, stahp Aug 11 06:46:12 5 year old iPhone can't run current ios... Aug 11 06:46:55 my I pad isn't even 4 years old and it can't run ios6 Aug 11 06:47:07 pfn: :( Aug 11 06:47:17 pfn: you need to pay if you want the latest ios! Aug 11 06:47:38 just responding to tpw_rules Aug 11 06:47:57 I really dislike the ios ecosystem Aug 11 06:48:05 pfn: why so? Aug 11 06:48:21 I early adopted and got out as soon as android 2.0 hit Aug 11 06:48:45 everything about it doesn't appeal to me Aug 11 06:48:54 ammm Aug 11 06:49:33 Theoretically speaking, I like Android better too... Sadly, for whatever reasons, my iOS thing tends to work better/faster/smoother than my Android thing.... Aug 11 06:51:17 BTW: I download data from my server, and I have a cache with that data in memory... Is there any method that gets called before my app is terminated? so I can write and flush all my "cache" to disk? before my app closes? Aug 11 06:59:30 onStop or onDestroy http://developer.android.com/training/basics/activity-lifecycle/stopping.html Aug 11 07:04:34 I'm talking about the Process not a specific Activity Aug 11 08:08:22 How can I display a live wallpaper from my app? Aug 11 08:08:33 I'm stuck with IWallpaperServiceWrapper not being public Aug 11 10:12:44 pfn: I worked out what happens, if you have a piece of code with a missing resource AS automatically imports android.R which messes up the rest of it when you remove the code Aug 11 10:50:26 can someone guide me on how can i reduce the resolution of a photo returned by camera api (ediaStore.ACTION_IMAGE_CAPTURE) to a certain width (kinda by giving the width, the height would adjuct as well)? Aug 11 11:03:48 omid8bimo: once you have the byte stream you could load it using say Bitmap and resize with the functions available there Aug 11 11:04:05 Does renderscript work with powervr GPUs? Aug 11 11:04:06 iirc the camera settings may also allow taking pictures at reduced resolution Aug 11 11:04:23 alankila: do you have any sample code for that? Aug 11 11:04:25 though I suggest always using size larger than the one you want and then slightly downscaling and never downscaling by factor larger than 2 Aug 11 11:04:32 omid8bimo: no Aug 11 11:05:07 if downscale factor exceeds 2, bitmap filtering must be enabled Aug 11 11:05:07 alankila: downscale by factory you mean isSampleSize? Aug 11 11:05:50 inSampleSize? that is a possibility. Aug 11 11:06:27 but it can only perform integer factor downscalings, so at some point you're forced to interpolate unless you can tolerate that sort of thing Aug 11 11:08:04 no, what I had in mind was more like BitmapFactory.decodeByteArray(bytes, 0, bytes.length).createScaledBitmap(...) Aug 11 11:08:36 * alankila doesn't understand why android API doesn't use overloading. BitmapFactory.decode() could exist and always just do the right thing Aug 11 11:08:53 alankila: can this BitmapFactory... happen on the fly and not resulting in ourofmemeory? Aug 11 11:09:14 omid8bimo: that is a function of how much memory you have available and how large images you get Aug 11 11:10:03 if we assume you can spend 20 MB to load an image, and decode it to 4 bytes per pixel, then you afford 5M pixels, so work with this sort of constraint, e.g. no more than 2000x2000 image in memory at once Aug 11 11:10:18 alankila: well how much memory android core assigns to any application? (can we tweak that, and more importantly, is it ok?) Aug 11 11:10:27 and use inSampleSize to downscale it early if you know the additional precision in the image doesn't avail you anything Aug 11 11:11:13 there is a largeheap option to enable in manifest that works on androids since 3.0. In general terms android assigns a constraint based on screen resolution assuming that the graphics assets are larger because screen has more pixels Aug 11 11:11:48 the heap size is device specific property and used to be 16, 24 or 32 MB not long ago. Not all memory counts against this though. Aug 11 11:12:26 iirc you can just malloc memory natively and it doesn't get counted, or you can upload graphics to GPU where it consumes GPU RAM and not yours Aug 11 11:13:12 liquidmetal: afaik powervr is the only kind of gpu right now that can deal with renderscript Aug 11 11:13:56 you need a very recent device to enjoy acceleration with renderscript, and supposedly less so with filterscript Aug 11 11:13:56 alankila, I thought tegra3 was the only one that could use it Aug 11 11:14:06 liquidmetal: hmm, maybe some powervr press release confused me Aug 11 11:15:50 in any case right now if you want to be sure to get hardware acceleration, then writing the code as GLSL shader and requiring opengl es 2.0 is more likely to work Aug 11 11:16:19 the downside is, I tried some of this and discovered the mobile graphics processors are not necessarily accurate Aug 11 11:16:52 a properly specified computing api that promises that e.g. floating point values have 32 bit precision & operations like sqrt and pow aren't approximated in some crude way may be required Aug 11 11:18:01 so render/filterscript looks like it might be better specified though there are some downsides like lack of denormal numbers -- bummer if you need them -- and likely some shortcuts will be taken with IEEE special values Aug 11 11:19:34 alankila, my goal is to do some calculations on the gpu Aug 11 11:19:40 in any case I do like renderscript/filterscript as a concept and suggest using it rather than NDK if you can for instance. Aug 11 11:20:08 I'm watching this video (http://www.youtube.com/watch?v=5jz0kSuR2j4#at=99) and it says all the computations happen on the CPU and rendering on the GPU Aug 11 11:22:13 yes, because GPU support is only planned and in any case they screwed up renderscript enough that they aren't sure it can be really accelerated, they have this thing called filterscript that is more likely to get accelerated Aug 11 11:23:14 the key differences are that filterscript operates on 32 bit types only, has no pointers, and forces a relaxed floating point precision mode, generally no denormal support. Aug 11 11:23:24 Hello Aug 11 11:23:32 I'm having a little problem with threads Aug 11 11:23:51 "Only the original thread that created a view hierarchy can touch its views." what exactly does this mean Aug 11 11:24:21 Phineas5: exactly what it says. In general treat it to mean you can't use threads other than the designated UI thread to manipulate any views. Aug 11 11:24:52 is there any way to get a website's content without using a thread? Aug 11 11:24:56 android has UI thread which is the application's default thread which calls things like onCreate and so on. It builds the views as well, therefore it is the only one that is allowed to update the views. Aug 11 11:25:30 Phineas5: threads aren't the problem. See AsyncTask, it's great for detached processing. Aug 11 11:25:30 I'm not updating any views in my thread, I'm calling a function in the main thread which updates the view Aug 11 11:26:43 okay I'm gonna try AsyncTask Aug 11 11:26:46 Phineas5: so what's the problem anyway Aug 11 11:28:13 basicly Aug 11 11:28:32 I'm trying to make a app where it sets a textView's text to a website's content Aug 11 11:28:37 and I want to have a refresh button Aug 11 11:28:52 which gets the website's content again and sets the text of the textView Aug 11 11:29:13 okay. the refresh button creates and fires asynctask, the asynctask's doInBackground gets the data from the website, onPostExecute updates the textview. Done. Aug 11 11:29:46 yep Aug 11 11:29:48 doing that Aug 11 11:36:09 other useful things to note: disable the button right after firing the task, enable it when the asynctask terminates, either in exception or whatever Aug 11 11:36:36 good idea Aug 11 11:36:39 it's working now Aug 11 11:36:41 thanks man :D Aug 11 12:00:36 I am working on an App where i want to open a mail client and allow user to enter mail ids to send mail.Once User clicks on send button mail should be sent and return back to the my app with all the mail ids i have sent mail to. I have done everything but i don't know how i can get the callback with all the mail ids user has sent mail to.Please if anyone knows anything i can do to get the mail ids would be a great help. Aug 11 12:31:17 hi hello Aug 11 12:31:44 how do i define styles for ui stuff, like buttons etc? (without having to apply a style on each element) ?? Aug 11 12:32:13 Has anybody worked with the Facebook sdk? I am trying to make an apklib out of it but I am obviously failing. Aug 11 12:37:48 I have a .apk on my phone, from which i would like to see the output (debug) text from when i run it. I have downloaded ADK and put my phone in developer mode, but i dont know where to go from here. Aug 11 12:39:52 nds_, read online tutorials for getting an adb setup, from there you can type 'adb lolcat' Aug 11 12:39:57 and it will show you debug output Aug 11 12:40:15 well Log.i/d/wtf/etcc() calls Aug 11 12:52:03 adb lolcat lol Aug 11 12:52:31 always makes me happy Aug 11 13:15:43 pfn: ping! Aug 11 13:17:55 pfn: i have some scala-related questions to ask you about, not anything about the merits of iOS vs Anroid Aug 11 13:17:57 android* Aug 11 13:18:36 i can talk about that too if you wish though Aug 11 13:19:00 if only there was some IRC mechanism to facilitate communications meant only for one person tpw_rules... Aug 11 13:19:19 poutine: where i'm from it's impolite to PM without asking... Aug 11 13:19:36 should a capital offence Aug 11 13:21:08 sorry if i'm bothering people, but he hasn't told me I can pm him Aug 11 13:21:30 tpw_rules: are you planning on scala? Aug 11 13:21:33 yup Aug 11 13:21:48 never done anything with android though, so i need help getting a dev environment and such set up Aug 11 13:22:47 java is not my thing Aug 11 13:23:04 tpw_rules: oh that's simple. just get android studio and create a new project Aug 11 13:23:15 you can link existing libs pretty easily Aug 11 13:23:53 i've also heard of things like scaloid and want somebody's opinion on them Aug 11 13:24:19 also i was reading docs yesterday, is it true that android destroys and recreates the activity when you rotate the screen? Aug 11 13:24:27 yes Aug 11 13:24:42 there are ways to manage it so that it's not really that big of a deal Aug 11 13:24:56 okay Aug 11 13:24:57 IIRC scala has a non-trivial startup cost Aug 11 13:25:24 i've heard proguard can solve a lot of that Aug 11 13:26:40 but java is really ugly to me so i don't plan on using it Aug 11 13:27:01 it's not bad once you get used to it Aug 11 13:27:11 http://clintshank.blogspot.com/2010/11/java-vs-scala-ceremony.html Aug 11 13:27:11 which is kind of like saying getting punched in the face is not so bad once you get used to it Aug 11 13:27:17 scala is overly complex Aug 11 13:27:28 how do you think so? Aug 11 13:28:02 it does too much and it's very hard to know exactly what's going on without being a scala demigod Aug 11 13:28:07 at least in my expiernce Aug 11 13:28:18 what sort of stuff were you trying to do? Aug 11 13:29:00 financial math calculation stuff. did it in F# instead. much better Aug 11 13:29:38 ahh Aug 11 13:30:00 problem with that is it isn't a JVM language Aug 11 13:30:06 python is still my go-to language Aug 11 13:33:08 i like c# the best Aug 11 13:33:20 good tooling, async/await, and can make me a sandwich Aug 11 13:33:42 I think scala to java is a bit like c++ to c Aug 11 13:33:54 there's obvious stuff that's clear improvement over java, but go too far and you end up in living hell Aug 11 13:34:23 only thing i can say is that IMO scala > java Aug 11 13:34:47 alankila: yep. Aug 11 13:34:59 i once fixed a bug in boost. :( Aug 11 13:37:08 tpw_rules: if you do end up using scala and it works out i would love to hear about your experiences Aug 11 13:37:29 right now i have most of the actual app in a java library Aug 11 13:37:31 i've used scala well with regards to other java-requiring ecosystems, specficially minecraft Aug 11 14:22:59 Sorry, my PC crashed so i didnt see if anyone answered my question about seeing an applications output in a console on my PC with ADK. Aug 11 14:24:59 nds_: adb logcat? Aug 11 14:41:14 hello guys. does the user agent switch feature works on chrome for android? Aug 11 14:43:18 Question: I followed google GCM introduction I wanted to implement the example that they provide… they declare a service that they don't explain further … any explanations? Aug 11 14:44:55 The Intro can be found here: http://developer.android.com/google/gcm/gs.html Aug 11 14:45:41 EditTexts in ListViews. Aug 11 14:45:54 anyone done battle with the focus finding after the ListView changes size? Aug 11 14:54:25 any idea why my beta test link downloads th elive old version Aug 11 14:58:10 jan1337z: intentservice is just a service that is fired up when an intent occurs and hangs around to process further intents that it has a filter for Aug 11 14:59:15 alankila, sorry still don't get it... Aug 11 15:00:06 Ash__: has to be the same google account, need to wait for propagation Aug 11 15:00:33 uploaded beta version yesterday and linked it to my community Aug 11 15:01:07 when i click link and accept beta testing then click the link at the bottom of the page which says download app its the live app and not the beta version Aug 11 15:01:20 Ash__: same exact google acocunt ? Aug 11 15:01:30 as in poublisher account? yeah Aug 11 15:04:04 alankila, can you give me a scenario? I don't understand why there is a BroadcastReceiver and an IntentService? Aug 11 15:13:51 jan1337z: broadcastreceiver is a general thing that listens for intents being broadcasted and gets called when the intent is fired, or if there is a sticky intent that the filter receiver. Aug 11 15:14:02 filter receives that is Aug 11 15:14:32 intentservice is a separate thread which is invoked to process an intent. It's typically fired with startService with intent argument that names the intentservice to be run, and any parameters that it needs are added to the intent. Aug 11 15:14:56 Yeah ok I got that Aug 11 15:15:28 thanks so far Aug 11 15:15:29 so anyway typically 2-way communication requires 2 broadcast receivers, or one broadcast receiver and something that fundamentally already receives intents such as intentservice Aug 11 15:15:40 so typically you'd use the broadcastservice to hear the response from the intentservice Aug 11 15:16:23 all this is pretty optional by the way. Nothing prevents you from running normal Threads or using other mechanisms if you are more familiar with them Aug 11 15:16:48 though android is its own beast and there are reasons why these verbose and clumy intents and broadcastreceivers are used, and it's about decoupling Aug 11 15:19:00 alankila, okay thnaks Aug 11 15:33:36 alankila, could you see any reason why a GCMBaseIntentService could not be started by the manifest declaration? Aug 11 15:33:44 or anybody else? Aug 11 15:34:16 I get the GCM Message but only by the BroadcastReceiver Aug 11 15:34:50 does the google play edition firmware check whatever it is checking for for wireless hotspot? Aug 11 15:35:21 any Otto wizards present? Aug 11 15:44:37 alankila: When renderscript first got HW acceleration, it was only on Tegra, Exynos, and Snapdragon, wasn't it? Aug 11 15:45:19 * alankila doesn't know Aug 11 16:20:00 funkbox, use my sbt plugin and scala on Android is easy Aug 11 16:20:52 pfn: hi Aug 11 16:21:11 have you run away yet? Aug 11 16:21:27 from? Aug 11 16:21:53 irc. nvm. anyway, i have no android background whatsoever and want to get started with scala on android and i've heard you know what you're talking aboiut Aug 11 16:21:55 about* Aug 11 16:22:25 no scala, either, I presume Aug 11 16:22:35 no, i'm okay with scala Aug 11 16:22:40 it'll be a learning curve Aug 11 16:22:43 not a wizard, but i've used it before Aug 11 16:22:56 get sbt, get the plugin and get started Aug 11 16:23:14 ever set it up with intellij? Aug 11 16:23:19 use intellij if you like Aug 11 16:23:27 sbt-idea Aug 11 16:23:28 are you jberkel? Aug 11 16:23:35 no Aug 11 16:23:48 what sbt plugin is yours then? Aug 11 16:23:54 I have my own, better plugin Aug 11 16:23:58 android-sdk-plugin Aug 11 16:24:25 ahh Aug 11 16:24:51 what about the acutal programming of an application with the android API? Aug 11 16:25:01 need to do a little more testing and I'll release 0.9.0 Aug 11 16:25:05 i've seen scaloid, have you heard of that before? Aug 11 16:25:31 yes,and I haven't used it, I have my own collection of implicits and helpers Aug 11 16:25:40 Hi guys, I'ld like to ask a small question. In my app, I'm storing data in the cache in the directory this.getCacheDir(), where 'this' is an Activity. When I want to get data from the cache in a widget, how can I get that data, without starting an Activity? Aug 11 16:26:10 anyway, I'm off and on here til Tuesday Aug 11 16:26:11 pfn: ahh. do you still use xml for GUI building? Aug 11 16:26:16 yes Aug 11 16:26:22 it's the best way Aug 11 16:26:28 any recommendations for actually making code? Aug 11 16:26:42 is there PreferenceDialog analagous in operation to PreferenceActivity ? Aug 11 16:27:11 but if you're not really available til tuesday, i can hang around til then Aug 11 16:27:23 by writing g it :p Aug 11 16:27:36 pfn: is there a perf penalty associated w/scala ? Aug 11 16:27:58 i've never written anything android before, are there specific scala tutorials or am i going to have to translate java? (which i can do) Aug 11 16:28:01 funkbox, depends on how side-effectless you go Aug 11 16:28:14 tpw_rules, translate Aug 11 16:28:20 fair enough Aug 11 16:28:29 i'll see what i can do to get this set up and playing with it Aug 11 16:28:37 funkbox, marginal overhead to massive if you destroy the heap Aug 11 16:29:07 if you're using a lot of anonymous objects as anonymous functions Aug 11 16:29:09 right? Aug 11 16:30:41 no Aug 11 16:31:26 lots of immutable stuff that gets recreated Aug 11 16:31:37 pfn: so if i write scala as i would C# minimal ? Aug 11 16:31:43 what about the initial load/startup cost ? Aug 11 16:31:48 funkbox, right Aug 11 16:31:54 none Aug 11 16:32:18 pfn: what about linking scala libraries into android Aug 11 16:33:26 depends on library, I probably wouldn't use scalaz Aug 11 16:33:37 anyway, g2g,later Aug 11 17:54:52 hey can anyone read this , or is my mirc defect? Aug 11 17:55:34 why are my menu items not showing on the actionbar when i use isRoom Aug 11 17:55:47 BulleTTime: yes we can, but using mirc is still a defect ;) Aug 11 17:55:54 haha :D Aug 11 17:55:58 ok thanks :) Aug 11 17:58:54 p_l: Agreed. XD Aug 11 18:01:21 hmm Aug 11 18:01:34 anyone know why a bitmap would be showing transparent for white? Aug 11 18:01:39 is it perhaps the way I created the bitmap? Aug 11 18:06:21 ahh I see..I was creating it from a layout that didn't have a bg color defined Aug 11 18:08:15 anyone familar with the android calendar app? Aug 11 18:08:47 i would like to change some settings within that app, from my app (maybe using intent? ) Aug 11 18:09:10 can i openup the settings from the calendar app and set some things? Aug 11 18:09:16 BulleTTime dunno, i would think you would use CalendarProvider though Aug 11 18:10:00 g00s, i would like to set the default reminder/alarm to off. is that possible with CalendarProvider? Aug 11 18:10:08 not sure Aug 11 18:10:14 me to :) Aug 11 18:11:04 i tried to set SharedPreferences , but that aint work. (well setting do work but it creates a new pref file) Aug 11 18:17:21 does loading a file from the cache dir automatically remove it form the cache dir? Aug 11 18:35:18 sounds like its best not to use a bitcoin wallet on android Aug 11 18:36:04 seems like you have too many words there Aug 11 18:36:14 best not use bitcoin Aug 11 18:36:46 i'm interested in this part "We recently learned that a component of Android responsible for generating secure random numbers contains critical weaknesses" Aug 11 18:37:27 yeah, broken SecureRandom is rather important Aug 11 18:37:48 http://d24w6bsrhbeh9d.cloudfront.net/photo/ajrAv6w_460s_v1.jpg Aug 11 18:37:51 er. Aug 11 18:37:57 sorry, wrong channel, ignore this please Aug 11 18:38:13 haha Aug 11 18:38:26 ;) Aug 11 18:39:15 what is the weakness? I hear a lot of paranoia about secure random numbers but if they simply read some crap from /dev/urandom or /dev/random they should be good to go Aug 11 18:41:54 I think people are always shooting themselves at the foot with the crazy paranoia they have about randomness, unwilling to use readily available almost random sources because they aren't quite random enough, when all you have to do is collect randomness by source into different pools and then blend that crap into prng periodically Aug 11 18:41:59 g00s, it seems people don't know the limitations of Java SecureRandom Aug 11 18:42:04 and they shot themselves in the foot Aug 11 18:42:14 Mavrik i'm just reading about it here http://armoredbarista.blogspot.com.au/2013/03/randomly-failed-weaknesses-in-java.html Aug 11 18:42:25 and then you get situations where random output is entirely predictable, or random numbers aren't available at sufficiently high rate, because they want the random shit to be so good :-/ Aug 11 18:42:58 g00s, yeah I've seen that one but afaik Android 4.x is using a BouncyCastle implementation anyway Aug 11 18:43:11 alankila, yeah, the catch is Aug 11 18:43:26 it seems people seed SecureRandom from source that doesn't have enough entropy Aug 11 18:43:31 thus f-ing everyhing up Aug 11 18:44:08 Hmm pathetic showing. I'm pretty sure all android devices have either random or urandom, why not, it's a fundamental linux service Aug 11 18:44:12 turning that stuff off would be stupid Aug 11 18:44:56 and if it does read 20 bytes and discards the top bit, that's *still* 20 * 7/8 bits, not quite 160 bits but 140 bits. Seems good enough to me ... unless this gets worse Aug 11 18:46:15 alankila, you're thinking way too low level Aug 11 18:46:17 https://www.cigital.com/justice-league-blog/2009/08/14/proper-use-of-javas-securerandom/ Aug 11 18:46:19 this is the catch Aug 11 18:46:33 alankila, you don't use /dev/urandom directly on android Aug 11 18:47:25 and you can mess up initialization of a Java class in such a way it won't be using /dev/urandom either >P Aug 11 18:47:29 tl;dr Aug 11 18:47:48 I find it astounding that 'new SecureRandom()' wouldn't be enough. And if it isn't, it's just a bug and will be fixed Aug 11 18:48:16 it sounds like the 140 bit issue is not all there is to it because they have apparently lost some part of the seed value due to incompetence Aug 11 18:48:25 that ;) Aug 11 18:48:26 so ... pathetic Aug 11 18:50:52 both /dev/random and /dev/urandom exist on my android device as expected. Had to check... :-p Aug 11 18:51:15 Hi guys Aug 11 18:51:27 I guess this proves that the sort of code that has no obvious way to test it is generally difficult to get right Aug 11 18:51:59 after all, debian ran for years with random seeds from one of 32768 values iirc Aug 11 18:52:05 in their ssh implementation Aug 11 18:52:07 :)) Aug 11 18:52:14 that was a very fun bug Aug 11 18:53:40 and these days if you get a virtual machine from a provider it might come with the preloaded fixed ssh host key Aug 11 18:53:50 because the system image already has ssh host key generated Aug 11 18:54:41 security is hard, and will always be hard, and mistakes will always happen. Which suggests we are insane to use C because of those reasons, or ever attempt anything more complicated than what approximately single human mind can easily comprehend. Aug 11 18:54:59 so... I'm going to sit in the corner and try to see which kind of peg goes into what kind of hole now Aug 11 18:55:24 might be best go into the basics Aug 11 19:05:01 can I force portrait mode for whole application in some way? Instead of setting this property for each activity on manifest file.. Aug 11 19:17:42 hey gusy ....i have to open a mail client from my app and want to know the email ids which user has entered and sent the mails to.Is there any trick i can do to get the mail ids ? Aug 11 19:25:46 Manny questions no answer Aug 11 19:26:08 lets make a android-dev app ! Aug 11 19:26:11 :P Aug 11 19:26:20 i also have a question Aug 11 19:29:21 Hey all! Any wisdom and best practices for bundling raw files? I'm working on a FOSS app for Burning Man, and I want to bundle some MapBoxTiles and a pre-populated database in res/raw Aug 11 19:29:57 but all the literature seems to suggest copying these files to external storage before use, and that just seems waseful. Is there no way to grab a File reference for a file in res/raw? Aug 11 19:31:23 dbro, I think you can only get an InputStream Aug 11 19:31:31 dbro, large resources are usually packed into expansion files though Aug 11 19:33:55 okay so with some research i came op with the idea of disable / cancel the alarms that the standard clock and agenda/calendar apps create. Can i cancel the Alarms these apps create by code? Aug 11 19:34:08 or Aug 11 19:34:24 can i call the settings and disable them? Aug 11 19:34:26 Mavrik: Thanks man. That's what I've found so far too. It's a bummer Aug 11 19:34:41 can i disable stuff from the android apps?\ Aug 11 19:36:04 BulleTTime, that depends on what exactly you can achieve Aug 11 19:36:11 calendar alarms are not the same as clock alarms Aug 11 19:36:28 and the way to "disable" them is dependant on what do you mean by "disabling" Aug 11 19:39:48 hi Mavrik, well let me explain. I am trying to sync a calendar app that syncs with the google calendar app. The only thing i would need is disable the calendar app alerts Aug 11 19:40:39 in the calendar app there's a setting that would do that, but i cant do that within java that aint work Aug 11 19:40:52 i tried prefs also Aug 11 19:41:12 hey guys ....i have to open a mail client from my app and want to know the email ids which user has entered and sent the mails to.Is there any trick i can do to get the mail ids ? Aug 11 19:41:55 BulleTTime, hmm, that's a good question actually Aug 11 19:42:03 Is there a way to destroy/disable calendar alarms? Aug 11 19:42:21 the problem is that the alarms are probably triggered by the app Aug 11 19:42:26 so you need to tell the APP to be silent Aug 11 19:42:33 i thought it was possible actualy Aug 11 19:42:35 and the app might not have an API for that Aug 11 19:42:42 yeah with a intent? Aug 11 19:43:29 can i perhaps open the calendar settings activity and set the alarmtype to 2 (off) Aug 11 19:43:53 or open app first and then tell that to do? Aug 11 19:45:01 i havent found any working thing, i tought that SharedPreferences might do it but that aint work Aug 11 19:51:28 its like, tell me why would there be a CalendarContract/Provider and many things to use without disabkle the agenda app within the code Aug 11 19:54:44 Would you like other apps to disable yours? Aug 11 20:04:53 ok, this is rather odd Aug 11 20:05:39 why can I add a String as a resource, but not a single integer, only an integer array? (according to eclipse) Aug 11 20:06:07 nvm, "Item" seems to be the answer Aug 11 20:06:07 Because eclipse Aug 11 20:06:23 because ADT Aug 11 20:06:36 is the answer Aug 11 20:07:00 really Aug 11 20:15:42 The documentation on repo is horrible. How can I update my current branch using repo? repo update isn't a thing? Aug 11 20:17:27 'repo sync' maybe Aug 11 20:18:06 alankila: I tried that it just syncs the "master" branch but not my fork Aug 11 20:18:17 oh. Aug 11 20:18:23 err... I don't know the answer in that case Aug 11 20:21:07 alankila: Turns out I overthought the problem. git pull from the root directory seems to have done it. -.- Aug 11 20:22:29 did JBQ work on repo ? Aug 11 20:23:07 is it possible to isolate a triangular area of a bitmap using 3 points? Aug 11 20:23:22 tnzr: you can make a clipping path from it I guess Aug 11 20:23:25 like if I know 3 points on the bitmap, is there a straightforward way to say, fill it, or mask it to be transparent, etc? Aug 11 20:23:33 alankila: hmm, ok I will google that Aug 11 20:25:13 thanks Aug 11 20:46:50 hm, do you guys think its a bad idea to check in a build.gradle with a nonspecific version dependency like 0.5.+ Aug 11 20:47:04 may not be able to reproduce the build Aug 11 20:51:04 is there any alternative to using addPreferencesFromResource for low API levels? Aug 11 20:51:18 no Aug 11 20:55:12 damn Aug 11 20:55:49 just suppress the deprecation warning Aug 11 20:56:01 or don't support low api Aug 11 20:56:06 i guess so Aug 11 20:56:22 havent really decided if I should support it or not Aug 11 21:26:22 omg, I only just discovered the API Demos sample app... life will be so much easier Aug 11 22:24:20 apple is getting lots of crash reports from my intellij install :) Aug 11 22:25:57 i'm sure they file them appropriately in /dev/null Aug 11 22:26:17 yeah, i wonder what they use them for Aug 11 22:30:00 prism Aug 11 22:32:28 bankai_ are you using intellij or AS ? Aug 11 22:32:47 IJ, i had bad experiences with AS and couldn't be arsed trying it again Aug 11 22:33:24 ok, would you have any recommendation for module / project structure using plain intellij but with the new gradle dir layouts ? Aug 11 22:33:52 basically, i'm using gradle to build Aug 11 22:33:54 never used gradle, sorry Aug 11 22:33:59 or, thx Aug 11 22:34:01
