title: How to add flags with my intent in the manifest file
body: <p>we know that there  are flags which we can add to our intent  using the addFlags() method in our java code. Is there any way we can add these flags in the manifest file itself instead of writing this in java code.
  I need to add REORDER_TO_FRONT flag for one of my activities in the manifest.</p>
  
  <p>How to achieve this ?</p>
