title: Most efficient way to detect Google Voice Search installation on Android device
body: <p>I wanted to ask,... What would be the most efficient way to detect the <a href="https://play.google.com/store/apps/details?id=com.google.android.voicesearch&amp;feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5nb29nbGUuYW5kcm9pZC52b2ljZXNlYXJjaCJd" rel="nofollow">Google Voice Search</a> (app id: com.google.android.voicesearch) installation on Android device?
  And is there any way of subsequently installing it without taking user to Play Market and back to application?</p>
