title: android programmatically blur imageview drawable
body: <p>I want to programmatically blur and unblur images in Android.</p>
  
  <p>I hear that android flag "blur" is no longer supported after API 14 , but I wanted to use Java methods anyway. My main problem is manipulating the bitmap from an Imageview drawable.</p>
  
  <p>How would I get the bitmap from an imageview and manipulate it (will probably use gaussian blur) and set it back to the imageview? I think the process involves extracting the drawable, converting the drawable to a bitmap, doing my blur method on that bitmap and then doing the reverse till it is set to the imageview again</p>
  
  <p>but I would like that process spelled out, thank you</p>
