• How to show a live Presentation from an Android phone?

  - by Pentium10

  This is not closely related to programming stuff, so I marked as community wiki. I am wondering how can I show a live Presentation from an Android phone? I want to put on a big screen my app, while I am presenting at a conference. I will directly interact with the phone during the presentation and I want the mobile screen visible on the big screen. Are there any apps that does this, or this is possible by the USB cable?

• Xcode: iPhone screenshots no longer work

  - by Chris Newman

  I can't be sure when this stopped working because I haven't used it for a while, but it was possibly since I upgraded to the 3.2 SDK. In Organizer, when I select the "Screenshots" tab and press "Capture", nothing happens. I've tried this with three different devices and I've restarted my Mac. What's happened, and how can I fix it?

• Is there anyway an app can use more than 16mb in memory?

  - by Sarevok

  I understand most Android devices have a 16mb limit (24mb on Nexus One) on the Java heap size. Is there any way a single app can use more memory than that? I know the native SDK doesn't have this limitation but I'd like to stick with Java.

• On Android, app jumps back to default Page on orientation change

  - by SteAp

  I tested my Xamarin.Forms app on iOS and Android and found this difference when I change the orientation of the mobile device: On iOS, the app keeps the current page On Android, the app seems to restart using the default page (or probably pop all pages except the first one). Since I've never seen this behavior in another Android app, I'd like to disable it. Moreover, I don't think that this behavior is Android default. Which property do I need to set the make the Android target behave as the iOS target?

• What is the best way to implement a Server-Client connection between an iPad and multiple iPhones?

  - by Infinite

  Based on a college-project I'm trying to realize a relatively simple game (Poker) where an iPad acts as Server and multiple iPod-Touchs connect to it as Clients. Gamekit seems to drop out, since those old ipod-touch-devices don't have bluetooth-support. Are there already some Frameworks out there simplifying the process, or do I have to fall back on TCP-Streaming-Sockets and implement it myself?

  - by Vaccano

  Is this: Box boxToFind = AllBoxes.Where(box => box.BoxNumber == boxToMatchTo.BagNumber); Faster or slower than this: Box boxToFind ; foreach (Box box in AllBoxes) { if (box.BoxNumber == boxToMatchTo.BoxNumber) { boxToFind = box; } } Both give me the result I am looking for (boxToFind). This is going to run on a mobile device that I need to be performance conscientious of.

• Why develop for people who disable/impair Javascript?

  - by Nissan Fan

  Can someone please enlighten me as to why it makes sense to develop websites that work without Javascript enabled? This is 2010 and besides some mobile browsers on antique phones and a few paranoids who limit Javascript I cannot think of a good reason to spend energy on this.

• Does Android 2.1's Browser Support HTML 5 and What Video Format Does It Play?

  - by John Giotta

  The company I work for produces allot of video and we want to target as many devices as possible, but the question came up of what does the Android do? I personally own an Android based phone running 2.1, but I can't seem to get the HTML 5 tag to work. Even when I can trigger the browser to playback the video it just throws a notification error that it can't. Are there guidelines to producing Android/HTML 5 compatible videos? Is it truly supported?

• Android "hello world" - versions

  - by Ianb

  Starter question: My "Hello World" attempt won't run, ("No compatible targets were found"), I think this is bacause I selected the latest version for my project (2.2), and the highest AVD version is 2.0.1. Does this make sense? Can I change my project version (haven't been able to find a way to do this), or do I have to start again? If the versions are not backwards compatible, what is the best version to use for the majority of Android devices out there? Thanks

• How do you get the pageYOffset of from the bottom of the window and not the top ( Javascript )?

  - by user782860

  I need to get the pageYOffset of the bottom of the viewable area, whether the user is zoomed in on the webpage or not, on Mobile Safari ( iPhone ). However pageYOffset returns the offset from the upper left corner of the window. Spec: "pageYOffset properties returns the pixels the current document has been scrolled from the upper left corner of the window" How do you get the page y offset from the bottom of the viewable area, (zoomed in or not) on the iPhone via Javascript?
