title: Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files are defined
body: <p>I'm getting an error at runtime stating: "DraggableGridViewSample] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/animoto/android/views/DraggableGridView$1;" </p>
  
  <p>How might this be avoided? I've tried removing the android-support-v4 jar from my libs folder and clicking Android Tools > Add Android Support Library but I cannot seem to resolve this issue. </p>
  
  <p>Any suggestions are greatly appreciated. </p>
