title: android TextToSpeech.LANG_AVAILABLE
body: <p>I'm still struggling with my tts. Everything works nicely in my emulator, but since my phone is swedish I need to check for the Locale.US (my texts are in english) and install it.
  And.. that's what I thought I did, but the Locale is unavailable and returns -1? Am I doing something wrong, I thought the english languages were always available?</p>

          // Note that a language may not be available, and the result will indicate this.
