can tell me i'm doing wrong? 'cus read in documentation, should available on sdk 10 too...

i had double fragment block inside activity: layout file.

when remove it, null google map:

this results in null:

map = ((supportmapfragment) getsupportfragmentmanager().findfragmentbyid(r.id.google_map)).getmap(); 

while layout file now

<android.support.v4.widget.drawerlayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent"> <!-- main content view --> <framelayout     android:id="@+id/content_frame"     android:layout_width="match_parent"     android:layout_height="match_parent">      <linearlayout         android:layout_width="fill_parent"         android:layout_height="match_parent"         android:orientation="vertical">          <fragment             android:id="@+id/google_map"             class="com.google.android.gms.maps.supportmapfragment"             android:layout_width="fill_parent"             android:layout_height="match_parent"             android:layout_weight="1" />     </linearlayout> </framelayout> <!-- navigation drawer --> <linearlayout     android:layout_width="240dp"     android:layout_height="match_parent"     android:layout_gravity="start"     android:gravity="bottom|center"     android:orientation="vertical">      <android.support.v4.widget.swiperefreshlayout xmlns:android="http://schemas.android.com/apk/res/android"         android:id="@+id/swipe_container"         android:layout_width="match_parent"         android:layout_height="match_parent">          <listview             android:id="@+id/left_drawer"             android:layout_width="240dp"             android:layout_height="match_parent"             android:layout_gravity="start"             android:background="#ffffff"             android:choicemode="singlechoice"             android:divider="@android:color/darker_gray"             android:dividerheight="0dp" />     </android.support.v4.widget.swiperefreshlayout> </linearlayout>
