title: Android application crashes by manipulating with canvas. Cordova 2.0.0/2.1.0
body: <p>My application uses cordova (v 2.1.0) to shoot pictures using tablet's cam and render them to a canvas. I use my own functions to move and zoom in/out this image in javascript.
  My application reboots after several zoom or move operations. Crash report from LogCat is below.</p>

  <p>When I move or zoom canvas no Cordova API functions is being invoking. Than why my app crashes?</p>
