  Remember that '==' in javascript will automatically typecast variables to be of the same type. My guess is you have "0" as a string rather than a number.

  You can run the following code in rhino to see this for yourself:

  var a = "0";
  
  if (a == 0) {
    // is true
  }
  
  if (a === 0) {
    // is false
  }
  
  switch (a) {
    case 0:
      // won't match
      break;
    default:
      // will
  }
  

• Try using Ti.API.info instead of alert and see if you get output. If so, then it's possible that your alert is coming up behind your window.

• This is just something REALLY stupid and silly to try…. but I'd just take a shot at adding the "default" case… maybe Androids compiler is being way more strict than it needs to be

  if that doesn't work, sorry for wasting your time :-/

• Thanks Don. Actually, in my code, I was using Ti.API.info and it doesn't work. I only switched it to alert in my sample above to make it a little clearer.

• oh yeah… totally overlooked the fact you were using "alert" like Don saw… definitely not the debugging method of choice in this environment

• @Kenn,

  @dasher did a quick test and it worked for him on Android. That's why we're postulating that it might actually be a different issue. Could you share more of the code and/or a put a Trace level log in a pastie and share it with us?

• Don, here's my actual code:

  search.addEventListener('return', function(e)
  {
      Ti.API.info('search.addEventListener called');
      search.blur();
      currentWord = e.value;
      Ti.API.info('currentWord = ' + currentWord);
      if (currentWord != ''){
          Ti.API.info('sortOrder = ' + sortOrder);
          switch (sortOrder){
              case 0:
                  Ti.API.info('Calling searchRhymes');
                  message = searchRhymes(currentWord);
                  break;
              case 1: message = searchRhymes(currentWord); break;
              case 2: message = searchSoundsLike(currentWord); break;
              case 3: message = searchContains(currentWord, 1); break;
              case 4: message = searchContains(currentWord, 2); break;
              case 5: message = searchContains(currentWord, 3); break;
          }
      }
      webview.html = htmlstart + message + htmlend;  
  });
  

  When the app runs, here's the log:

  [INFO] Launching Android emulator...one moment
  [INFO] Building RhymeNow for Android ... one moment
  [INFO] Waiting for the Android Emulator to become available
  [INFO] Copying project resources..
  [INFO] Tiapp.xml unchanged, skipping class generation
  [INFO] Manifest unchanged, skipping Java build
  [INFO] Re-launching application ... RhymeNow
  [INFO] Launching application ... RhymeNow
  [INFO] [7,7899] search.addEventListener called
  [INFO] [42,7941] currentWord = test
  [INFO] [1,7942] sortOrder = 0
  

  Here's a Trace level log

  As you can see, even though sortOrder == 0, the case 0: never executes. However, if I replace the switch/case statement with the following, it works just fine:

  
  if (sortOrder == 0){
      message = searchRhymes(currentWord);
  } else if (sortOrder == 1){
      message = searchRhymes(currentWord);
  } else if (sortOrder == 2){
      message = searchContains(currentWord, 1);
  } else if (sortOrder == 3){
      message = searchContains(currentWord, 1);
  } else if (sortOrder == 4){
      message = searchContains(currentWord, 2);
  } else if (sortOrder == 5){
      message = searchContains(currentWord, 3);
  }
  

  There are other switch/case statements in the app as well, and none of them execute.

• Damien, that was it! I changed my switch statement to

  switch (parseInt(sortOrder)){
  

  and that solved the problem.

  What's troubling about this is that the switch statement worked well on iPhone, but broke on Android.

  Thanks for your help!
