title: C# XAMARIN Android apk installation problems
body: <p>I created small app in xamarin and I have a problem with install .apk file from my mobile application for Adroid.</p>
  
  <p>When i installed .apk on my android device fist time i don't have any problems. Application ilstalled correctly and also works correctly. But when i make changes in project then archive it again and repeat steps to make .apk file it won't install on android device. Message on android is: "instalator was stopped".</p>
  
  <p>Maybe i should change something in .android properties? I have no idea why it won't work</p>
