public class mainactivity extends activity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);     } } 

your min sdk in 8. should use supportmapfragment

<fragment class="com.google.android.gms.maps.supportmapfragment" android:id="@+id/map"   android:layout_width="match_parent" android:layout_height="match_parent"/> 

your activity must extend fragmentactivity.

make sure have added support library

also make sure imported below

import android.support.v4.app.fragmentactivity;   import com.google.android.gms.maps.supportmapfragment; 

make sure have referenced google play services library project.

you can download sdk manager , follow suggestion in below link.

importing google-play-service library showing red x next reference android

as side note if have updated adt rev 22 make sure check android private libraries in oerder export tab of java build path.clean , build. ignore if not required.

also make sure have enabled google maps android in services tab of gogle api console.
