Android's Log.wtf Method

• eLobato 15y ago
  Lol, funny fact is that I have been collaborating with dpkg team in Debian and they created an identical function in C to report ANY error condition. I've read a lot of //D'OH and //ROFLMAO comments in rhythmbox source code so I guess this is pretty common over open source devs within the Linux community!

  See also: public static boolean isUserAMonkey() Returns "true" if the user interface is currently being messed with by a monkey. http://developer.android.com/reference/android/app/ActivityManager.html#isUserAMonkey() http://developer.android.com/reference/android/app/ActivityM...

    This is related to http://developer.android.com/guide/developing/tools/monkey.html http://developer.android.com/guide/developing/tools/monkey.h..., where you can actually test your user interface with a pseudo-monkey.

      Also related to that: http://www.folklore.org/StoryView.py?story=Monkey_Lives.txt http://www.folklore.org/StoryView.py?story=Monkey_Lives.txt (how a similar tool was used on the original Macintosh)
      • JulianMorrison 15y ago
        And this explains isUserAMonkey() Bill Atkinson came up with the idea of defining a system flag called "MonkeyLives" (pronounced with a short "i" but often mispronounced with a long one), that indicated when the Monkey was running. The flag allowed MacPaint and other applications to test for the presence of the Monkey and disable the quit command while it was running, as well as other areas they wanted the Monkey to avoid. This allowed the Monkey to run all night, or even longer, driving the application through every possible situation.

      Amazing how android docs fail to link to anything...
      • inoop 15y ago
        Android docs are pretty terrible anyway. Have fun finding out what a 'Looper' is for or how it even works without using stack overflow. Then be amazed and horrified. And then there are gems like WiFiManager.getScanResults(), which according to the docs returns a List<ScanResult>. Except that it's actually implemented as try { return [do native call]; } catch (RemoteException ex) { return null; }. So actually it returns a list except sometimes it returns null, which I have seen happen and it caused my app to force-close. There's shit like this all over the place. No wonder so many apps crash on random devices. So now any time I want to call a piece of the Android API I haven't worked with before I have to go find the source to make sure it's not doing something unexpected because I can't trust these Google monkeys to properly document their stuff. Sigh.
        • lsb 15y ago
          Yeah, this is why I love Haskell's type system. You'd be able to implement that as a Maybe [WifiResult], maybe Just a list of wifiresults or maybe Nothing, copying directly, but you'd probably want to have your datatype be Either String [WifiResult], either you get on the Left an error string or on the Right the list of wifiresults.
          • Deestan 15y ago
            And more importantly, if a function has [WifiResult] as the defined return type, you can be absolutely definitely sure that you get a list back. This is not something inherently unique to Haskell. Any strictly typed language could easily have chosen to not let null be a member of all classes. Or at the very least add some "non-nullable" qualifier to types.

  Another gem: http://developer.android.com/reference/android/hardware/SensorManager.html#GRAVITY_DEATH_STAR_I http://developer.android.com/reference/android/hardware/Sens... gives a gravity constant, on the death star, in imperial units...
  • scotth 15y ago
    Except that they're not...those are metric units.
  • varunsrin 15y ago
    It says Empire units (m/s^2), not Imperial Units. So its just SI Units.
  • ben1040 15y ago
    I was too busy cracking up at GRAVITY_THE_ISLAND, defined as 4.815162, to notice the Death Star reference.
• daleharvey 15y ago
  I like the description What a Terrible Failure adb lolcat was another andoid easter egg that made me laugh

  instead of cutesy shit like that, how about documenting stuff like customizing input methods. the SoftKeyboard sample doesn't have a single usage datum online. I, ahem, googled it. How do I enable a custom keyboard for just one text entry widget? oops, didnt mean to interrupt the cute fest with actual question. fucking morons.
