title: xamarin.forms know memory usage both for android and ios
body: <p>I am trying to develop android and iOS application using xamarin.forms. And already completed the main part that includes <code>Canvas</code> drawing. For that, I have used <code>Skiasharp</code>, to perform operations on bitmap images.</p>
  
  <p>Now, in android,
  1. If I try to dispose bitmaps that I initialized before I get <code>SIGSEGV</code> fatal error. (I think this issue is not OS specific)
  2. When I continuously run my app for 20-22 minutes, app crashes suddenly.</p>
  
  <p>And in iOS,
  my iphone gets hanged when I run my app for long time. And it doesn't start until I uninstall app from iFunBox in my pc.</p>
  
  <p>I wanted to ask if there are ways in xamarin.forms or in native projects to find out where my memory is leaking.
  How can I know how much memory of RAM is actually being used at the moment ?</p>
  
  <p>Thank you</p>
