  • Singelton on iPhone Simulator vs Singelton on real Device

    - by Helge Becker
    I am using a Singelton for some shared stuff. In the simulator, the app crashes ocasionally. Tracking the crash down shows that the the properties of my Singelton became dealocated. Those crashes never happend on a real device. Does the iPHone simulator handle memory managemend different? GC maybe? Changed the singelton to match this pattern. The iPhone Simulator dont crash now, but I am not sure about the memory handling on the real device. I assume that this solution will cause problems. What do you think?

  • Turn Bluetooth On and Off in Andriod 1.5 (SDK level 3)?

    - by pcm2a
    There are tons of pay and free bluetooth toggles on the market that work with Android 1.5 (SDK level 3). The problem is there is no visible API for this! Does anyone have any working code snippits on how to enable and disable bluetooth that works on Android 1.5? I assume you must have to use some kind of reflection for it. There are some examples over on anddev.org, but they only work with Android 1.1 or lower. This is for Android 1.5 (SDK level 3) and not Android 2.0 or greater. In Android 2.0 or later Google added easy to use APIs.

  • How to receive a datastream from a device on your computer, in C#

    - by WebDevHobo
    I plan to build a small audio-recorder app in C#. My laptop has a built in Microphone that's always active, so I want to use that as an early-stage test. I would simply start recording, save the file as a .wav or even use the LAME dll to make it into an MP3. The problem is, I don't know how to contact that microphone. Do I use a library that can detect a device, or do I just catch a stream of bytes from the port that the device is on? I don't have any experience with receiving data from connected devices. I suppose that I'll need to enter all the data into a byte array and then Serialize that into a WAV file, but I'm not sure. Can I get some pointers on this subject?

  • How do I update the system wallpaper in an Android 1.6 service after changing it with setWallpaper()

    - by Majakk
    So basically the code "almost" works - the problem is that the system does not appear to know that the system wallpaper have been changed or does not do anything about it. Starting and closing another app manually appears to enforce an update. In an event call the following is done: getApplicationContext().setWallpaper(pWallOne); Is there some way of telling the android system to update the graphics or to do some cheap trick that forces it to? Any help or tip would be very much appreciated!!

  • mobile device - different background - media query not working

    - by AMC
    Live site. This is my first attempt at utilizing a different CSS for mobile devices vs. regular screens. To do this, I'm using- @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { background: url('img/background.jpg') no-repeat center center fixed; background-size: cover; height: 100%; } However, it doesn't seem to be working (I can only test on iPhones). Any ideas as to why that may be? I've also tried @media all to no avail.
