Can't launch Android Emulator: "Type Error"



I've created a fresh mobile project and tried to launch it on the Android emulator.

  • I've selected the Android SDK as asked
  • Titanium shows the Android SDK green/ok/installed
  • I've installed the 1.5, 1.6 SDK and Google API v4 ( as mentioned here: http://developer.appcelerator.com/question/651/running-in-emulator-for-android-fails )
  • Installed Java version: java version "1.6.0-oem"

Here's the trace output:

Please help, can't even start with Titanium right now..

  • my issue was even simpler to solve:

    Titanium asked for the Android SDK 1.5 (api level 3), so I selected the sdk's platform subfolder: android-sdk-windowsplatformsandroid-3 Interestingly, Titanium returned a success message.

    However, correctly one must point to the sdk root folder.

    Sorry for bugging you folks (but really, Titanium shouldn't say "success" if only the folder exists, it should at least check if the needed stuff's really there :)

  • If you run aapt v from command line, you see Android 1.6 in the results?

    Generally, these old instructions apply, except they don't mention 1.6 (which is now required).

    Also, you're showing the same error as this support incident, so having a look there might help.

    If still no luck, Marshall or Don will probably pipe in here.

    I hope it helps! I've voted your question up to give it a little attention, in case Marshall or Don are lurking.
