Dec 19 03:26:00 well java.io apparently has no complaint Dec 19 03:26:27 well i mean can you compile a program that uses only java.io Dec 19 03:26:37 hello world , whatever Dec 19 03:26:47 have not tried Dec 19 03:27:03 try that Dec 19 03:27:14 if you miss awt, i think other things are broken aswell Dec 19 03:27:27 create a file on disk, whatever Dec 19 03:27:30 really now Dec 19 03:27:39 can I include java.io onto my other android project tictactoe Dec 19 03:27:46 that is working Dec 19 03:27:50 ok Dec 19 03:28:24 aaah Dec 19 03:28:26 look here Dec 19 03:28:27 http://stackoverflow.com/questions/6344654/how-to-add-java-awt-image-package-in-android Dec 19 03:28:45 Android has its own graphics libraries (android.graphics). Dec 19 03:28:49 lol Dec 19 03:28:57 miss awt? oh dear Dec 19 03:29:02 oh ok Dec 19 03:29:05 so then... Dec 19 03:29:07 what do I do Dec 19 03:29:08 android doesn't use awt, obviously Dec 19 03:29:14 how do I get awt to work Dec 19 03:29:17 you don't Dec 19 03:29:20 android does not use awt Dec 19 03:29:21 rewrite it to use andriod.graphics Dec 19 03:29:32 uh Dec 19 03:29:35 man it's a lot of a code Dec 19 03:29:45 android does not use awt, you will not use awt on android Dec 19 03:29:47 not even my code Dec 19 03:29:48 rewrite it to work correctly Dec 19 03:29:56 Tal Vu, yeah.. maybe you can find third party awt emulator on web Dec 19 03:30:05 what? Dec 19 03:30:13 but its not part of the standard Dec 19 03:30:23 this is the source code for the app I'm supposed to port to iOS Dec 19 03:31:12 well, porting is sometimes more then just pressing compile button Dec 19 03:31:16 http://stackoverflow.com/questions/16140431/android-the-type-java-awt-image-cannot-be-resolved-it-is-indirectly-referenced Dec 19 03:31:52 hey cool Dec 19 03:31:57 try it Tam_Vu Dec 19 03:32:08 where is project properties Dec 19 03:32:16 donno man Dec 19 03:32:36 i am not andriod programmer, i am asking questions about C and andriod myself)) Dec 19 03:34:40 oh that is probably for eclipse Dec 19 03:39:12 port to ios? how's that related to android then Dec 19 03:40:20 well I need to build it on the android simulator Dec 19 03:40:24 in android studio Dec 19 03:40:27 so I can figure out what's going on Dec 19 03:40:36 I guess the issue is that Dec 19 03:40:46 java.awt is used by commonsimagingv1 library Dec 19 03:41:47 What are some attractive options for storing persistent application data (config. info.) which has the form of arrays of strings and primitives? Dec 19 03:42:10 shared preferences Dec 19 03:43:06 i think he ment andriod, not ios Dec 19 03:43:14 because there is no java on ios iphone Dec 19 03:43:29 robovm works on ios Dec 19 03:43:39 and there's intel multi-os engine Dec 19 03:43:41 which also runs on ios Dec 19 03:43:41 pfn, it only seemed to support storing individual numeric types and string sets Dec 19 03:43:50 HGBG, a string array is a set of strings Dec 19 03:44:14 pfn how can I get this to work Dec 19 03:44:16 -.- Dec 19 03:44:17 you don't Dec 19 03:44:21 it's not an android project Dec 19 03:44:32 pfn, it doesn't provide ordering guarantees which I need Dec 19 03:44:33 well he showed me the app yesterday Dec 19 03:44:38 running on android phone Dec 19 03:44:50 HGBG, and there's tons of ways to fake ordering guarantees Dec 19 03:44:51 is it possibly outdated Dec 19 03:44:59 no Dec 19 03:45:03 it never built for android Dec 19 03:45:07 I mean he's using eclipse ADT Dec 19 03:45:17 java.awt does not exist for android, period Dec 19 03:45:18 pfn, yes, but it was worth asking if there was a better option Dec 19 03:45:25 HGBG, there isn't Dec 19 03:45:28 I read a bit about that -.- Dec 19 03:45:51 well are you sure pfn Dec 19 03:45:56 you sure it didn't exist for Eclipse ADT Dec 19 03:46:09 I'm not answering anymore Dec 19 03:46:11 wasting my time Dec 19 03:48:27 well even when I search for it Dec 19 03:48:33 it seems like people are talking about java.awt and ADT Dec 19 03:50:46 So I just straight up removed commonsimaging Dec 19 03:54:48 http://postimg.org/image/tlceb8y61/ Dec 19 03:54:49 pfn Dec 19 03:54:53 what do you suggest there Dec 19 03:56:10 do what it says Dec 19 03:56:22 pfn: know anything about graphics? Dec 19 03:56:28 Suggestion: use tools:overrideLibrary="com.google.zxing.client.android" to force usage Dec 19 03:56:29 that thing? Dec 19 03:58:24

Dec 19 03:58:30 put that above android:minSdkVersion="11" Dec 19 03:58:30 android:targetSdkVersion="18" /> Dec 19 03:59:03 Error:The prefix "tools" for attribute "tools:overrideLibrary" associated with an element type "uses-sdk" is not bound. Dec 19 04:04:26 why does google make so many useful methods package private Dec 19 04:04:29 why do they hate me Dec 19 04:04:54 One of the reasons why I hate the principle of making things private by default Dec 19 04:05:16 Actually private is fine, it's final I have a beef with for libraries Dec 19 04:05:31 i prefer the "we're all adults here" philosophy Dec 19 04:05:36 yup Dec 19 04:10:46 yeah, so many final and package-private functions that are perfectly ok being used from 3rd parties Dec 19 04:11:26 it's very annoying Dec 19 04:11:47 package private isn't the end of the world, though Dec 19 04:11:57 workaround: create code in package Dec 19 04:12:10 private and final is a problem (private is final for all intents and purposes of course) Dec 19 04:13:58 what does that mean? create code in package Dec 19 04:14:03 does reflection work Dec 19 04:14:21 what do you mean what does that mean, exactly what that says Dec 19 04:14:37 create code in that package that you want to use the method in Dec 19 04:14:59 * pfn has hacked so many google libraries because of that Dec 19 04:15:01 even if it's some decompiled google library Dec 19 04:15:14 either copy-paste, or throw an extension class into the library's package Dec 19 04:15:28 Error:(17, 0) Gradle DSL method not found: 'android()' Dec 19 04:15:46 copy-paste usually ends up involving pasting in half the classes from the lib Dec 19 04:15:57 or throw an extension class into the library's package Dec 19 04:16:17 how would you modify do that Dec 19 04:16:27 java.lang.IllegalArgumentException: You need to use a Theme.AppCompat theme (or descendant) with the design library. Dec 19 04:16:29 what do? Dec 19 04:16:40 by typing "package THE.PACKAGE.YOU.WANT.IT.TO.GO.INTO;" Dec 19 04:16:47 hmmmm Dec 19 04:16:51 interesting Dec 19 04:16:55 seems rather obvious Dec 19 04:17:00 I just made a starter project and got that error after trying to change the text field Dec 19 04:17:12 morenoh149, the answer is dead obvious Dec 19 04:17:19 just....never thought of that Dec 19 04:17:24 i blame javascript and php Dec 19 04:17:42 javascript and php have terrible namespace issues Dec 19 04:19:06 is there such a thing as the new marshmellow app auto-backup but to a custom server rather than Google Services? Dec 19 04:19:11 does javescript have namespaces? Dec 19 04:19:21 and it was a late addition in php, i never used it Dec 19 04:19:29 it's not obvious to me. pretty much the generated project has an error. Dec 19 04:21:34 of course it doesnt....i should know that....android is rotting my mind Dec 19 04:22:39 morenoh149, that's happened to me a few times Dec 19 04:23:54 the generated code kinda sucks anyway imo, it's just a reference, you're gonna have to change it massivly anyway Dec 19 04:25:17 even so I'm just getting started with android. So i dunno. Dec 19 04:25:58 i'm hoping AS 2 brings real time feedback of errors without having to do build :| Dec 19 04:30:22 ugh Dec 19 04:30:25 I'm just NOT going to be able to build this project Dec 19 04:30:38 now I see the source files that actually DO use the commons imaging library Dec 19 04:30:46 which in turn uses java.awt Dec 19 04:30:47 which I've been told does not work on Android? Dec 19 04:30:54 can anyone recommend a good intro to android development? a free one? Dec 19 04:31:16 and I've been told this is not even an android project Dec 19 04:31:16 which makes no sense to me Dec 19 04:31:22 unrelated I know, but xda has really gone to shit Dec 19 04:31:54 lol Dec 19 04:31:57 g00s they are going to have to do that kinda shit to make dev tolerable Dec 19 04:32:00 they were cool back in their winmo days Dec 19 04:32:22 MooGoo - even in the last like 4mo its a total pain in the ass to just navigate subthreads or login Dec 19 04:32:32 i miss windows mobile Dec 19 04:32:39 lets hire someone who is on bathsalts to design our website Dec 19 04:32:48 MooGoo - you really shouldnt Dec 19 04:32:58 it was so like....permissive tho Dec 19 04:32:59 ms has some interesting stuff in the latest win10 for mobile devices Dec 19 04:33:00 but Dec 19 04:33:03 you could whatever the fuck u wanted Dec 19 04:33:13 we'll see if they ever do anythign with it Dec 19 04:33:58 their tech stack is far superior in just about every way than android Dec 19 04:34:09 i believe it Dec 19 04:34:15 ron_frown some food for thought http://blog.ezyang.com/2015/12/the-convergence-of-compilers-build-systems-and-package-managers/ Dec 19 04:34:30 but they manage to fuck up the ui and extendability and app store etc Dec 19 04:34:32 okay. so I have clean build, rebuild, etc.. I have compile files('libs/org.apache.http.legacy.jar'), put the jar in the directory, etc.. Still reports it as Warning:Unable to find optional library: org.apache.http.legacy. Any ideas? Dec 19 04:34:37 so badly nobody wants any part of it =) Dec 19 04:35:53 I think the fact that maven and gradle actually made things way worse than what was there before it Dec 19 04:36:09 and java community puts them up on a pedestal Dec 19 04:36:21 tells you exactly what kinda people the community is made up of Dec 19 04:37:29 i think how omnisharp + rosylyn work are the way forward Dec 19 04:37:36 ehhhhh Dec 19 04:37:41 it works Dec 19 04:37:43 VS code is pretty dumb by itself, but with omnisharp gets superpowers Dec 19 04:37:57 omnisharp is really just mostly roslyn tho Dec 19 04:38:22 I went to go suck in as2 stuff the other day Dec 19 04:38:36 and remembered that last time I did that I had 15g of system images and sdks Dec 19 04:38:46 eff it =) Dec 19 04:40:02 g00s they managed to get in their initial pass at performance tuning, kestrel handling 1.024mil requests per second Dec 19 04:40:12 this looks good https://www.udacity.com/course/developing-android-apps--ud853 Dec 19 04:40:14 for somethign thats beta beta Dec 19 04:40:17 thats pretty respectable Dec 19 04:40:41 morenoh149 - honestly def dont get a book Dec 19 04:40:57 I'd just read tuts... try to make sure they are as late as possible Dec 19 04:41:18 google has blogs with their stuff on it, though I dont know if they've been keeping it relevant Dec 19 04:46:21 has anyone else here messed with the flutter.io shit? Dec 19 04:49:46 Does anyone know why if I have a widget that launches a configuration activity when added, and call setResult(RESULT_OK, resultValue) and then hit the home button, the widget doesnt get added? Dec 19 04:50:06 * impliednude sighs Dec 19 04:50:07 BUT if I do the same as above and call setResult() and then finish() right after, it DOES get added? Dec 19 04:52:04 okay. so I have clean build, rebuild, etc.. I have compile files('libs/org.apache.http.legacy.jar'), put the jar in the libs/ directory, etc.. Still reports it as Warning:Unable to find optional library: org.apache.http.legacy. Any ideas? Dec 19 04:54:28 maven made things worse? Dec 19 04:54:31 what crack are you smoking Dec 19 04:55:45 Ah to answer my own question...I guess its because finish() closes the activity right then and returns the result specified in the setResult() back to the callers onActivityResult Dec 19 04:56:22 Where as it doesnt get added without finish() as the activity is still running in the background. Someone correct me on that if im wrong. Dec 19 04:57:46 because that's how setResult works Dec 19 04:57:54 when you press home, you didn't complete the activity Dec 19 04:57:56 you just skipped out of it Dec 19 04:58:28 pfn: yep thats what I thought. ty Dec 19 04:58:29 pressing back can return a result, however, if you set a result before hand Dec 19 04:59:10 pfn: because isnt hitting the back button the same as calling finish()/onDestroy()? Dec 19 04:59:26 it calls finish indirectly Dec 19 04:59:36 and finish will indirectly call onDestroy Dec 19 05:10:34 Hmm is it possible to return the result before calling finish()? I need the widget to be added regardless, and I dont want to make an "Ok" button to call finish() with. Dec 19 05:11:27 hehe this is great http://thomasbyttebier.be/content/03-blog/14-the-best-icon-is-a-text-label/washing-icons.png Dec 19 05:14:03 tennis balls :D Dec 19 05:17:05 Hey friends, I have a problem. Dec 19 05:17:27 I'm trying to get a google-services.json config file from https://developers.google.com/identity/sign-in/android/start-integrating#get-config Dec 19 05:17:50 I click GET A CONFIGURATION FILE, but the link it takes me too just loads. Dec 19 05:17:57 Is it just me? Dec 19 05:18:27 to* Dec 19 05:21:08 Hi, I want to develop for android Dec 19 05:21:14 i know java/C++/C Dec 19 05:21:42 can i develop for android on CentOS, maybe in a virtual machine Dec 19 05:22:58 jacob___ why in a VM ? don't know how well running an emulator will work that way Dec 19 05:23:21 CentOS should work though Dec 19 05:23:54 Is it bad to call a fragments methods from the parent activity? Dec 19 05:24:06 its fine Dec 19 05:24:11 Sweet Dec 19 05:24:15 i mean, not lifecycle methods of course Dec 19 05:24:24 Yeah, just a public method I wrote Dec 19 05:24:54 ok Dec 19 05:27:31 so i cant see anything that tells me but if i have a return inside a try block is the finally executed? Dec 19 05:27:32 is it ok to call setSupportActionBar multiple times? like if a fragment need a special AB, provide it to the hosting activity (which may already have done that) Dec 19 05:28:04 mark4 sure Dec 19 05:28:17 ty, thought it would be but needed to make sure :) Dec 19 05:37:43 hahahahaha https://code.google.com/p/android/issues/detail?id=186273 Dec 19 05:37:52 i was so confused Dec 19 05:38:16 orbyt_, then call finish onPause Dec 19 05:38:28 orbyt_, but that's bad Dec 19 05:38:54 pfn: Thats exactly what I thought. How else would it be done? Dec 19 05:39:08 how do you allow the user to cancel then? Dec 19 05:39:25 home is an implicit cancel action Dec 19 05:39:27 so should back be Dec 19 05:39:39 The widgets already been dragged and dropped onto the screen Dec 19 05:39:42 so? Dec 19 05:39:51 a user can't change their mind? Dec 19 05:40:02 of course they can, drag it up and drop to remove Dec 19 05:40:19 that's annoying Dec 19 05:40:23 but if you insist, finish onPause Dec 19 05:40:42 but dragging it onto the screen, having the config show up and than hitting the home button only to have to go back to the widget list and add it again is far more annoying Dec 19 05:40:59 if you think so, do that Dec 19 05:41:01 I don't agree Dec 19 05:41:33 back and home typically mean cancel Dec 19 05:41:43 and placing it anyway even though a user presses back is frustrating Dec 19 05:41:50 So If you already picked your widget and dropped it onto the screen, youd expect the back button to not add the widget? Dec 19 05:42:03 if there's a configuration step, absolutely Dec 19 05:42:22 Yea, its more of a settings/help activity more than a configuration Dec 19 05:42:33 what would you recommend in that case Dec 19 05:42:40 why would a widget need help... Dec 19 05:43:21 this uses some acronyms and other values that not everyone interested in the widget may know Dec 19 05:44:23 I could have the user just hit the app icon to launch the activity but i had thought that having it pop up automatically when adding would be nicer Dec 19 05:45:02 you could just add a help button to the widget itself Dec 19 05:45:37 Well AFAIK you can only set a click listener on the entire widget itself, not specific views Dec 19 05:45:46 false Dec 19 05:45:46 That might work though... Dec 19 05:45:50 oh really? Dec 19 05:49:23 Ah your right. Regardless, is the finish() in onPause the only way to get the result returned? Is there really no way to forcefully return a result without destroying the activity? Dec 19 05:50:07 that's what returning a result means Dec 19 05:53:40 okay. so I have clean build, rebuild, etc.. I have compile files('libs/org.apache.http.legacy.jar'), put the jar in the libs/ directory, etc.. Still reports it as Warning:Unable to find optional library: org.apache.http.legacy. Any ideas? Please... ^_^ Dec 19 05:56:17 pfn: I mean theres probably a method in the onDestroy() process that returns the result to the calling activity, why shouldnt it be possible to do the same without actual destroying the activity Dec 19 05:56:29 actually* Dec 19 06:07:12 Hi Guys, Is there a way to programmatically check what archtype a .so file was compiled for? Dec 19 06:07:27 What ABI Dec 19 06:16:50 no Dec 19 06:16:57 well, yes Dec 19 06:17:01 read it and check for magic headers Dec 19 06:19:37 this place I work is so odd. They hired probably 12 fresh college grads Dec 19 06:19:48 2 of them are developers, the rest are BA's Dec 19 06:19:55 i honestly have no clue what they do Dec 19 06:20:14 pfn: Sorry I didnt get that Dec 19 06:20:22 but I think they could possibly be replaced with Outlood Dec 19 06:20:24 .so files are binary files right/ Dec 19 06:20:24 orbyt_, why are you so fixated on destroying activities Dec 19 06:20:25 *Outlook Dec 19 06:22:41 pfn: I want the Widget to be set after the dragndrop regardless if the activity is destroyed or whatever Dec 19 06:23:58 But from what you've said and the lack of SO answers calling finish() or having the activity destroyed any other way seems to be the only option to have the result returned. Dec 19 06:28:31 then finish regardless Dec 19 06:30:04 ? what do you mean Dec 19 06:31:23 what's unclear, finish onpause Dec 19 06:32:22 wasnt sure what your meant by regardless. anyway thanks. Dec 19 06:32:48 you* Dec 19 06:33:49 hey people. Is there any message broker for android ? Dec 19 06:34:27 lxsameer need to be more specific Dec 19 06:37:12 g00s, something like Apache Kafka or RabbitMQ Dec 19 06:37:36 hm, there is java RabbitMQ client ... Dec 19 06:38:04 or you can use websocket to talk to RabbitMQ Dec 19 06:38:16 but as far as running broker on the phone, i haven't heard of anything Dec 19 06:39:57 no I need a client Dec 19 06:41:23 i think okhttp has a websocket client. not sure how robust / conformant it is to the spec tho Dec 19 06:41:41 you can also use mqtt paho client if thats your thing Dec 19 06:44:06 okay. so I have clean build, rebuild, etc.. I have compile files('libs/org.apache.http.legacy.jar'), put the jar in the libs/ directory, etc.. Still reports it as Warning:Unable to find optional library: org.apache.http.legacy. Any ideas? Please... ^_^ Dec 19 06:47:38 useLibrary org.apache.http.legacy is only for compileSdkVersion 23 and up Dec 19 06:49:25 which I did Dec 19 06:49:48 It just isn't working at all and I am pulling my hair out Dec 19 06:50:16 then you don't have sdk 23 properly installed Dec 19 06:51:10 putting the jar in libs is orthogonal to useLibrary Dec 19 07:53:34 is it possible to read the sensors more than 60 times a second? Dec 19 07:53:53 i need to read it about 130 times a second Dec 19 09:43:33 One3yed: yes Dec 19 09:43:54 depends on the device though. Dec 19 10:17:52 How everyone today?:) Dec 19 10:28:09 do you know any mobile sqlite <-> sql server sync framework? Dec 19 11:01:38 gdrc, I've yet to find a good sync library for DBs for mobile :/ Dec 19 11:03:00 For very simple use-cases, here's a "meta library" ;-) http://stackoverflow.com/questions/12340083/consolidating-changes-when-syncing-with-a-server-from-offline-localstorage/12346606#12346606 Dec 19 11:03:25 Coding it is left as an excercise. Dec 19 11:09:16 Hello Dec 19 11:10:22 Needed some insight in android programming Dec 19 11:12:58 mhm Dec 19 12:07:55 anyone know how i might animate an image to rotate on top of another image? in html/css i'd do this by rendering one image on top of the other and applying a css rotate anim, can I do similar in android? e.g. a FrameLayout with one image behind and one in the foreground Dec 19 12:07:59 Hi friends! Is there any chance to use Android Studio on NixOS? Dec 19 12:08:33 storkme: I'm not certain, but maybe you need to use RenderScript? Dec 19 12:10:42 had a little look, renderscript seems a bit overkill maybe? Dec 19 12:14:14 storkme: yep, also it works only on SDK 3+ Dec 19 12:15:50 storkme, do you need to do it in realtime? Fast? or render ahead? Dec 19 12:17:01 sure, real time. Just looking into ObjectAnimator now Dec 19 12:17:38 Make a FrameLayout and add two imageviews to it Dec 19 12:17:40 rotate one. Dec 19 12:17:43 apply alpha Dec 19 12:32:57 neat, it was as easy as that. Thanks. Dec 19 12:58:38 tricky part I suppose will be positioning the items correctly Dec 19 13:41:26 is this an okay way to connect to a PHP file on a server and return data to my app? http://pastebin.com/GGUGXAWw Dec 19 13:51:58 so I need to use support-v4 to use a ViewPager? seems bizarre Dec 19 13:53:25 you should be using StringBuilder to concatenate the strings, and you should be able to get the character set from the HttpUrlConnection (isn't that done automatically?) Dec 19 13:53:29 @ thornekey Dec 19 14:00:28 Ah Dec 19 14:00:36 could you give me an example storkme? Dec 19 14:00:42 and other than that does it look fine? Dec 19 14:02:56 thornekey: http://stackoverflow.com/questions/4666748/java-how-to-read-bufferedreader-faster for the stringbuilder, as for the charset thing i think you can just remove the "iso-1234" argument you're passing (might be wrong on that) Dec 19 14:06:01 thanks, ill take a look :) Dec 19 14:08:19 oh, storkme thats simple enough ahaha Dec 19 14:15:49 storkme, is this the correct way ? http://pastebin.com/5mVhiBDd Dec 19 14:17:32 move text = builder.toString() to outside of the while loop Dec 19 14:20:06 So do we have any RxJava focused ORM yet? Dec 19 14:21:04 didn't Realm announce first class rx support recently? Dec 19 14:25:35 thanks storkme Dec 19 14:26:53 storkme, they still have the limitation of where you can't carry an object over thread boundaries which makes Rx usage extremely problematic Dec 19 14:27:22 Are there any more libraries like json-path to query json objects for android? Dec 19 14:33:04 hm storkme when i add a println for the text nothing is displayed, but there are no errors saying it didnt connect or anything Dec 19 14:39:03 Wait, does System.out.println go to logcat? Dec 19 14:43:48 yes Dec 19 14:44:01 okk Dec 19 14:51:17 how does one query json objects? Dec 19 14:57:33 im getting this error: "A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks. Dec 19 14:57:34 java.lang.Throwable: Explicit termination method 'close' not called" Dec 19 14:57:42 think it has to do with InputStream Dec 19 15:16:09 why do i get the "ERROR" msg in post? http://pastebin.com/YUhpSxtB Dec 19 15:18:59 because you didn't close Dec 19 15:19:12 i used in.close() Dec 19 15:19:57 pfn, where do i need to close? :) Dec 19 15:20:06 finally Dec 19 15:20:53 after the catch? and is that all ill need to put in it Dec 19 15:21:03 do i need to move it btw or duplicate it Dec 19 15:22:29 your for loops should contain only a single try Dec 19 15:23:31 so merge all into one Dec 19 15:34:05 when i put it in a finally it gives me a nullpointer Dec 19 15:38:33 then fix it so it isn't null Dec 19 15:38:46 null pointer exceptions are easiest to fix Dec 19 15:41:36 so I'm calling Intent intentApp = new Intent(MainActivity.this, CapturingActivity.class); MainActivity.this.startActivity(intentApp); to start a new activity Dec 19 15:41:51 how might I call a public function within CapturingActivity associated with this new activity? Dec 19 15:42:18 huh Dec 19 15:43:59 when i go to close my InputStream (in finally) it says that the input stream may not have initialized Dec 19 15:44:26 so fix it so that it is Dec 19 15:44:42 these are java basics you need to learn Dec 19 15:44:44 i put a null on it. cos i need to do it properly ina try. Dec 19 15:44:57 however when i do it that way Dec 19 15:45:13 i get the null error so im thinking the try isnt working..? correct? Dec 19 15:45:46 the check for null Dec 19 15:45:49 then Dec 19 15:46:43 ok :) Dec 19 15:46:45 so pfn.. Dec 19 15:47:16 how exactly do you write a class within a libraries package? I tried it and got the same method not public cant be accesed out of package Dec 19 15:47:39 somehow I doubt it considers this the same package just cause it has the same words Dec 19 15:47:40 told you already Dec 19 15:47:50 package library.package; Dec 19 15:48:02 that's what I did Dec 19 15:48:15 i had to make a new directory and everything Dec 19 15:48:23 then it works fine Dec 19 15:48:35 is it lieing to me? Dec 19 15:48:52 you're not doing what you think you're doing Dec 19 15:49:23 and i guess that got rid of the null error but im still getting it retuned false Dec 19 15:50:09 I made a new directory structure, android.support.design.widget, and put my class in that folder....with the same package name Dec 19 15:50:40 I mean....it's just a static method that takes an AppBarLayout object and tries to access it Dec 19 15:50:57 and then? Dec 19 15:51:10 I get a big red wavy line under the method call saying you cant do this Dec 19 15:51:30 what is the method call, how are you sure that this is the right package Dec 19 15:52:19 it works fine Dec 19 15:52:44 final int getMinimumHeightForVisibleOverlappingContent() in AppBarLayout Dec 19 15:53:11 android.support.design.widget package Dec 19 15:53:11 it's final Dec 19 15:53:21 and it's not static Dec 19 15:53:32 right well, im passing in an appbarlayout object Dec 19 15:53:45
