i saw lot of posts same issue, none of fizes helped me. stuck in on week, explaining scenario, maybe can help. followed steps in google tutorials. running on real device android version 2.3.6

my activity_mapa.xml file:

<?xml version="1.0" encoding="utf-8"?> <fragment xmlns:android="http://schemas.android.com/apk/res/android"       android:id="@+id/map"       android:layout_width="match_parent"       android:layout_height="match_parent"       android:name="com.google.android.gms.maps.mapfragment"/> 

my mapa.java file:

package com.gerdau.produtos;  import android.os.bundle; import android.app.activity; import android.view.menu;  public class mapa extends activity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_mapa);     }      @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.mapa, menu);         return true;     }  }
