android - MapView displays blank, but MapFragments work normally -

-

hello i'm using fragment based layout in application - goes fine - using 1 special mapfragment , other pagefragments display data. mapfragment works fine - map display no problems , able draw on etc.

now wanted add small map view 1 of pagefragments.

i tried like:

<com.google.android.gms.maps.mapview         xmlns:android="http://schemas.android.com/apk/res/android"         xmlns:map="http://schemas.android.com/apk/res-auto"         android:id="@+id/mapview"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:background="#00000000"         android:clickable="true"         map:uicompass="true"         map:uizoomcontrols="true"         map:zorderontop="true" >     </com.google.android.gms.maps.mapview>

no xml errors, etc. app working - pagefragment correctly displayed, map view remains blank. ideas?

you must forward lifecycle methods activity or fragment mapview working. in particular:

  • oncreate(bundle)
  • onresume()
  • onpause()
  • ondestroy()
  • onsaveinstancestate()
  • onlowmemory()

http://developer.android.com/reference/com/google/android/gms/maps/mapview.html

just in case missed, valid google maps api v2. if not override these methods may still see map grid, map controls etc, map imaginary not visible.
