title: Android app error - Duplicate id 0x7f04000f, tag null, or parent id 0x0 with another fragment for com.google.android.gms.maps.SupportMapFragment
body: <p>I'm trying to make a simple android app and am having trouble fixing this bug.</p>
  
  <p>The app has a 4 tab fixed button navigation and the error occurs when on the 4th tab and switching to another tab. Being on any other page works fine but the 4th tab is causing a fatal error every time. There is nothing on that page except a TextView element. Can anyone help me figure out what's wrong or point me in the right direction? </p>
