• Cannot run Android "Camera Preview" sample

  - by noisesolo

  The sample I'm referring to is: CameraPreview. The program simply force closes upon start up. I've also tried other camera demos that have the same problem. I'm trying to run the samples on my Nexus One and the emulator with the same problem on both. I'm not even sure if the emulator should be able to run them or not. Based on LogCat, the error is: 06-08 16:39:10.483: ERROR/AndroidRuntime(6726): Uncaught handler: thread main exiting due to uncaught exception 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): java.lang.RuntimeException: Fail to connect to camera service 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.hardware.Camera.native_setup(Native Method) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.hardware.Camera.<init>(Camera.java:110) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.hardware.Camera.open(Camera.java:90) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at com.example.android.apis.graphics.Preview.surfaceCreated(CameraPreview.java:69) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.view.SurfaceView.updateWindow(SurfaceView.java:454) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.view.SurfaceView.dispatchDraw(SurfaceView.java:287) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.view.View.draw(View.java:6557) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.widget.FrameLayout.draw(FrameLayout.java:352) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.view.ViewGroup.drawChild(ViewGroup.java:1531) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.view.View.draw(View.java:6557) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.widget.FrameLayout.draw(FrameLayout.java:352) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at com.android.internal.policy.impl.PhoneWindow$DecorView.draw(PhoneWindow.java:1830) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.view.ViewRoot.draw(ViewRoot.java:1349) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.view.ViewRoot.performTraversals(ViewRoot.java:1114) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.view.ViewRoot.handleMessage(ViewRoot.java:1633) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.os.Handler.dispatchMessage(Handler.java:99) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.os.Looper.loop(Looper.java:123) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at android.app.ActivityThread.main(ActivityThread.java:4363) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at java.lang.reflect.Method.invokeNative(Native Method) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at java.lang.reflect.Method.invoke(Method.java:521) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 06-08 16:39:10.494: ERROR/AndroidRuntime(6726): at dalvik.system.NativeStart.main(Native Method) All I did to try out the sample was create a new Android 2.1update1 Project, named everything according to the supplied Java file, copied the Java file from the URL to the CameraPreview.java file, then run it. Am I supposed to do anything else? Any help would be appreciated. Thanks in advance.

• Get the rendered text from HTML (Delphi)

  - by Daisetsu

  I have some HTML and I need to extract the actual written text from the page. So far I have tried using a web browser and rendering the page, then going to the document property and grabbing the text. This works, but only where the browser is supported (IE com object). The problem is I want this to be able to run under wine also, so I need a solution that doesn't use IE COM. There must be a programatic way to do this that is reasonable.

• Strange Play Framework 2.2 exceptions after trying to add MySQL / slick

  - by Mike Cialowicz

  I'm working on a Play 2.2 application, and things have gone a bit south on me since I've tried adding my DB layer. Below are my build.sbt dependencies. As you can see I use mysql-connector-java and play-slick: libraryDependencies ++= Seq( jdbc, anorm, cache, "joda-time" % "joda-time" % "2.3", "mysql" % "mysql-connector-java" % "5.1.26", "com.typesafe.play" %% "play-slick" % "0.5.0.8", "com.aetrion.flickr" % "flickrapi" % "1.1" ) My application.conf has some similarly simple DB stuff in it: db.default.url="jdbc:mysql://localhost/myDb" db.default.driver="com.mysql.jdbc.Driver" db.default.user="root" db.default.pass="" This is what it looks like when my Play server starts: [info] play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000 (Server started, use Ctrl+D to stop and go back to the console...) [info] Compiling 1 Scala source to C:\bbq\cats\in\space [info] play - database [default] connected at jdbc:mysql://localhost/myDb [info] play - Application started (Dev) So, it appears that Play can connect to the MySQL DB just fine (I think). However, I get this exception when I make any request to my server: [error] p.nettyException - Exception caught in Netty java.lang.NoSuchMethodError: akka.actor.ActorSystem.dispatcher()Lscala/concurren t/ExecutionContext; at play.core.Invoker$.<init>(Invoker.scala:24) ~[play_2.10.jar:2.2.0] at play.core.Invoker$.<clinit>(Invoker.scala) ~[play_2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$Implicits$.defaultContext$lzycompu te(Execution.scala:7) ~[play_2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$Implicits$.defaultContext(Executio n.scala:6) ~[play_2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$.<init>(Execution.scala:10) ~[play _2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$.<clinit>(Execution.scala) ~[play_ 2.10.jar:2.2.0] The odd thing is that the 2nd request (to the exact same URL, same controller, no changes) comes back with a different error: [error] p.nettyException - Exception caught in Netty java.lang.NoClassDefFoundError: Could not initialize class play.api.libs.concurr ent.Execution$ at play.core.server.netty.PlayDefaultUpstreamHandler.handleAction$1(Play DefaultUpstreamHandler.scala:194) ~[play_2.10.jar:2.2.0] at play.core.server.netty.PlayDefaultUpstreamHandler.messageReceived(Pla yDefaultUpstreamHandler.scala:169) ~[play_2.10.jar:2.2.0] at com.typesafe.netty.http.pipelining.HttpPipeliningHandler.messageRecei ved(HttpPipeliningHandler.java:62) ~[netty-http-pipelining.jar:na] at org.jboss.netty.handler.codec.http.HttpContentDecoder.messageReceived (HttpContentDecoder.java:108) ~[netty-3.6.5.Final.jar:na] at org.jboss.netty.channel.Channels.fireMessageReceived(Channels.java:29 6) ~[netty-3.6.5.Final.jar:na] at org.jboss.netty.handler.codec.frame.FrameDecoder.unfoldAndFireMessage Received(FrameDecoder.java:459) ~[netty-3.6.5.Final.jar:na] The URL / controller that I'm requesting just renders a static web page and doesn't do anything of any significance. It was working just fine before I started adding my DB layer. I'm rather stuck. Any help would be greatly appreciated, thanks. I'm using Scala 2.10.2, Play 2.2.0, and MySQL Server 5.6.14.0 (community edition).

• Keep IIS 7 URL Rewrite module from matching /ScriptResource.axd

  - by D.R. Payne

  I have a website and I have installed URL Rewrite using Web Platform Installer. I wish to allow a user friendly URL like www.foo.com/123456 to go to www.foo.com/page.aspx?blah=123456. Using the User-friendly URL template accomplishes this except that the created rule also matches all of the /scriptresource.axd?blahblah created by ASP.NET which of course breaks most functionality. My initial attempts to exclude the script resource files have failed. The regex generated by the tool is ^([^/]+)/?$

• Tetris Piece Rotation Algorithm

  - by coppercoder

  What are the best algorithms (and explanations) for representing and rotating the pieces of a tetris game? I always find the piece rotation and representation schemes confusing. Most tetris games seem to use a naive "remake the array of blocks" at each rotation: http://www.codeplex.com/Project/ProjectDirectory.aspx?ProjectSearchText=tetris However, some use pre-built encoded numbers and bit shifting to represent each piece: http://www.codeplex.com/wintris Is there a method to do this using mathematics (not sure that would work on a cell based board)?

The application have a good internet connection and there is no problem reaching the app server-side api. I see in analytics that lots of startups and click-events the past few days are lost, even I know the traffic is normal since i can see statistics from the the server api. In the analytics reports I see a day by day under-reporting. So the problems seems to be spreading/growing to all the devices using this application. Im wondering why google does not answer this in their mail-groups - several people have complained about this...well, well... I found this thread relevant: http://stackoverflow.com/questions/682560/java-net-socketexception-broken-pipe But, I'm still not sure if there is anything I can do to fix it or not. If there is nothing I can do to fix it, I guess its not my fault that it got broken. But i got a feeling it is, since the problem got dramatically worse on the last deploy to Android market. Anyone else with experience on Google Analytics for android ?

• Path.Combine for Urls?

  Path.Combine is handy, is there a similiar function in the framework for Urls? I'm looking for syntax like this: Url.Combine("Http://MyUrl.com/", "/Images/Image.jpg") ...Which would return: "Http://MyUrl.com/Images/Image.jpg" ...Of course string concatenation would be fine here since the '//' would be handled intelligently by the browser. But it feels a little less elegant.

• Cover flow in iPhone/iPad

  - by hgpc

  I use FlowCoverView (http://chaosinmotion.com/blog/?p=295) for cover flow, which I discovered through this question: http://stackoverflow.com/questions/767048/iphone-coverflow FlowCoverView last update was in mid-2009 and it's performance is not very good when the images are taken from the documents directory. Yet, there are lots of apps with cover flow. I was wondering if we all use FlowCoverView, or if there's is a better, maybe iPad-optimized solution that I haven't heard about yet. What do you use to implement cover flow in iPhone/iPad?

• How can I force a tree itemrenderer to redraw during a drag and drop operation?

  - by swidnikk

  I have a tree control with a custom item renderer. The item renderer has different states that should be set while an item is being dragged over the item renderer. I understand from reading this post http://forums.adobe.com/message/2091088 that the 'right way' to do this is to override the 'getCurrentState' method and append some text. I do that. Now in my tree control I handle the drag over event and get a reference to the itemrenderer that is being dragged over and I set the boolean 'dragOver' property to true. Now I just need to force my itemRenderer to redraw. I can't figure that out. A workaround, is to just set the currentState of the itemRenderer. My question then, how can I force my itemRenderer to refresh? (and I've tried calling validateNow, invalideDisplayList/Properties/Size, to no avail) <?xml version="1.0" encoding="utf-8"?> <s:MXTreeItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx"> <fx:Script> <![CDATA[ import mx.events.DragEvent; import mx.events.FlexEvent; import spark.layouts.supportClasses.DropLocation; public var dragOver:Boolean = false; override protected function getCurrentRendererState():String { var skinState:String = super.getCurrentRendererState(); if( dragOver ) skinState += "AndDragOver"; trace('getCurrentRendererState', skinState); return skinState; } ]]> </fx:Script> <s:states> <s:State name="normal" /> <s:State name="hovered" /> <s:State name="selected" /> <s:State name="normalAndDragOver" stateGroups="dragOverGroup" /> <s:State name="hoveredAndDragOver" stateGroups="dragOverGroup" /> <s:State name="selectedAndDragOver" stateGroups="dragOverGroup" /> </s:states> ...

Are there serious flaws, either in the repository hosting or the bug tracking features that would make it difficult to recommend it? Do you have any other experiences with it or opinions of it that you would like to share? If you have used other non mercurial hosted repository/bug tracking systems, how does it compare? (If I understand correctly, the best format for this type of community-wiki style question is one answer per option, if you have experienced if several) Background I have been looking into options for setting up a bug/issue tracking database and found some valuable advice in this thread and this. But then I got to thinking that a hosted solution might not only solve the problem of tracking bugs, but might also solve the problem we have accessing our mercurial source code repositories while at customer sites around the world. Since we currently have no way to serve mercurial repositories over ssl, when I am at a customer site I have to connect my laptop via VPN to my work network and access the mercurial repositories over a samba share (even if it is just to synce twice a day). This is excruciatingly slow on high latency networks and can be impossible with some customers' firewalls. Even if we could run a TRAC or Redmine server here (thanks turnkey), I'm not sure it would be much quicker as our internet connection is over-stretched as it is. What I would like is for developers to be able to be able to push/pull to/from a remote repository, servicing engineers to be able to pull from a remote repository and for customers (both internal and external) to be able to submit bug/issue reports. Initial options The two options I found were Assembla and Jira. Looking at Assembla I thought the 'group' price looked reasonable, but after enquiring, found that each workspace could only contain a single repository. Since each of our products might have up to a dozen repositories (mostly for libraries) which need to be managed seperately for each product, I could see it getting expensive really quickly. On the plus side, it appears that 'users' are just workspace members, so you can have as many client users (people who can only submit support tickets and track their own tickets) without using up your user allocation. Jira only charges based on the number of users, unfortunately client users also count towards this, if you want them to be able to track their tickets. If you only want clients to be able to submit untracked issues, you can let them submit anonymously, but that doesn't feel very professional to me. More options Looking through MercurialHosting page that @Paidhi suggested, I've added the options which appear to offer private repositories, along with another that I found with a web search. Prices are as per their website today (29th March 2010). Corrections welcome in the future. Anyway, here is my summary, according to the information given on their websites: Assembla, http://www.assembla.com/, looks to be a reasonable price, but suffers only one repository per workspace, so three projects with 6 repos each would use up most of the spaces associated with a $99/month professional account (20 spaces). Bug tracking is based on Trac. Mercurial+Trac support was announced in a blog entry in 2007, but they only list SVN and Git on their Features web page. Cost: $24, $49, $99 & $249/month for 40, 40, unlimited, unlimited users and 1, 10, 20, 100 workspaces. SSL based push/pull? Website https login. BitBucket, http://bitbucket.org/plans/, is primarily a mercurial hosting site for open source projects, with SSL support, but they have an integrated bug tracker and they are cheap for private repositories. It has it’s own issues tracker, but also integrates with Lighthouse & FogBugz. Cost: $0, $5, $12, $50 & $100/month for 1, 5, 15, 25 & 150 private repositories. SSL based push/pull. No https on website login, but supports OpenID, so you can chose an OpenID provider with https login. Codebase HQ, http://www.codebasehq.com/, supports Hg and is almost as cheap as BitBucket. Cost: £5, £13, £21 & £40/month for 3, 15, 30 & 60 active projects, unlimited repositories, unlimited users (except 10 users at £5/month) and 0.5, 2, 4 & 10GB. SSL based push/pull? Website https login? Firefly, http://www.activestate.com/firefly/, by ActiveState looks interesting, but the website is a little light on details, such as whether you can only have one repository per project or not. Cost: $9, $19, & £39/month for 1, 5 & 30 private projects, with a 0.5, 1.5 & 3 GB storage limit. SSL based push/pull? Website https login. Jira, http://www.atlassian.com/software/jira/, isn’t limited by the number of repositories you can have, but by ‘user’. It could work out quite expensive if we want client users to be able to track their issues, since they would need a full user account to be created for them. Also, while there is a Mercurial extension to support jira, there is no ‘Advanced integration’ for Mercurial from Atlassian Fisheye. Cost: $150, $300, $400, $500, $700/month for 10, 25, 50, 100, 100+ users. SSL based push/pull? Website https login. Kiln & FogBugz On Demand, http://fogcreek.com/Kiln/IntrotoOnDemand.html, integrates Kilns mercurial DVCS features with FogBugz, where the combined package is much cheaper than the component parts. Also, the Fogbugz integration is supposedly excellent. *8’) Cost: £30/developer/month ($5/d/m more than either on their own). SSL based push/pull? SourceRepo, http://sourcerepo.com/, also supports HG and is even cheaper than BitBucket & Codebase. Cost: $4, $7 & $13/month for 1, unlimited & unlimited repositories/trac/redmine instances and 500MB, 1GB & 3GB storage. SSL based push/pull. Website https login. Edit: 29th March 2010 & Bounty I split this question into sections, made the questions themselves more explicit, added other options from the research I have done since my first posting and made this community wiki, since I now understand what CW is for. *8') Also, I've added a bounty to encourage people to offer their opinions. At the end of the bounty period, I will award the bounty to whoever writes the best review (good or bad), irrespective of the number of up/down votes it gets. Given that it's probably more important to avoid bad providers than find the absolute best one, 'bad reviews' could be considered more important than good ones.

• How do I change the URL for the wordpress author archive page?

  - by Ben Burleson

  Instead of www.example.com/author/xyz, I want to use www.example.com/artist/xyz. I was hoping it was as easy as copying author.php to artist.php in my theme directory, but no such luck. Where does wordpress handle the special processing for the author archive pages? .htaccess rewriting is another option, but I wasn't able to get anything to work with the existing wordpress rewrite rules. Thanks,

• Android - Key Dispatching Timed Out

  - by Donal Rafferty

  In my Android application I am getting a very strange crash, when I press a button (Image) on my UI the entire application freezes and after a couple of seconds I getthe dreaded force close dialog appearing. Here is what gets printed in the log: WARN/WindowManager(88): Key dispatching timed out sending to package name/Activity WARN/WindowManager(88): Dispatch state: {{KeyEvent{action=1 code=5 repeat=0 meta=0 scancode=231 mFlags=8} to Window{432bafa0 com.android.launcher/com.android.launcher.Launcher paused=false} @ 1281611789339 lw=Window{432bafa0 com.android.launcher/com.android.launcher.Launcher paused=false} lb=android.os.BinderProxy@431ee8e8 fin=false gfw=true ed=true tts=0 wf=false fp=false mcf=Window{4335fc58 package name/Activity paused=false}}} WARN/WindowManager(88): Current state: {{null to Window{4335fc58 package name/Activity paused=false} @ 1281611821193 lw=Window{4335fc58 package name/Activity paused=false} lb=android.os.BinderProxy@434c9bd0 fin=false gfw=true ed=true tts=0 wf=false fp=false mcf=Window{4335fc58 package name/Activity paused=false}}} INFO/ActivityManager(88): ANR in process: package name (last in package name) INFO/ActivityManager(88): Annotation: keyDispatchingTimedOut INFO/ActivityManager(88): CPU usage: INFO/ActivityManager(88): Load: 5.18 / 5.1 / 4.75 INFO/ActivityManager(88): CPU usage from 7373ms to 1195ms ago: INFO/ActivityManager(88): package name: 6% = 1% user + 5% kernel / faults: 7 minor INFO/ActivityManager(88): system_server: 5% = 4% user + 1% kernel / faults: 27 minor INFO/ActivityManager(88): tiwlan_wifi_wq: 3% = 0% user + 3% kernel INFO/ActivityManager(88): mediaserver: 0% = 0% user + 0% kernel INFO/ActivityManager(88): logcat: 0% = 0% user + 0% kernel INFO/ActivityManager(88): TOTAL: 12% = 5% user + 6% kernel + 0% softirq INFO/ActivityManager(88): Removing old ANR trace file from /data/anr/traces.txt INFO/Process(88): Sending signal.

It seems unlikely as several other buttons do the same without issue. How about the native layer? Could some code I've built with the NDK be causing the issue? Any other ideas as to what the cause of the issue might be?

• Android: ViewHolder pattern and different types of rows?

  - by tomash

  ViewHolder pattern improves ListView scrolling framerate, as seen in following example: http://developer.android.com/intl/de/resources/samples/ApiDemos/src/com/example/android/apis/view/List14.html Is it possible to keep this pattern while using different kind of Views for different rows? In other words, is it possible to do something like: public View getView(int position, View view, ViewGroup parent) { // calculate viewID here if (view == null || *view is not null but was created from different XML than viewID* ) { view = mInflater.inflate(viewId, null);
