and activity_main.xml

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingbottom="@dimen/activity_vertical_margin" android:paddingleft="@dimen/activity_horizontal_margin" android:paddingright="@dimen/activity_horizontal_margin" android:paddingtop="@dimen/activity_vertical_margin" tools:context=".mainactivity" >  <textview     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="@string/hello_world" />  <fragment     android:name="com.google.android.gms.maps.supportmapfragment"     android:id="@+id/map"     android:layout_width="match_parent"     android:layout_height="match_parent"     />    </relativelayout> 

and androidmanifest.xml :

  <?xml version="1.0" encoding="utf-8"?>   <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.googlev2.android"     android:versioncode="1"      android:versionname="1.0" >     <uses-sdk     android:minsdkversion="8"     android:targetsdkversion="17" />    <uses-permission android:name="android.permission.internet" />   <uses-permission android:name="com.google.android.providers.gsf.permission.read_gservices"/>  <uses-permission android:name="android.permission.write_external_storage"/>  <uses-permission android:name="android.permission.access_coarse_location" />  <uses-permission android:name="android.permission.access_fine_location"/>       <permission      android:name="com.googlev2.android.permission.maps_receive"      android:protectionlevel="signature">     </permission>      <uses-permission      android:name="com.googlev2.android.permission.maps_receive"/>   <uses-feature     android:glesversion="0x00020000"     android:required="true"/> <uses-permission android:name="android.permission.access_network_state"/>  <application     android:allowbackup="true"     android:icon="@drawable/ic_launcher"     android:label="@string/app_name"     android:theme="@style/apptheme" >       <!-- <meta-data         android:name="com.google.android.maps.v2.api_key"         android:value="aizasydcil7-t3bphxgv2q-a77vnrcyjq_strgi"/> -->      <activity         android:name="com.googlev2.android.mainactivity"         android:label="@string/app_name" >         <intent-filter>             <action android:name="android.intent.action.main" />              <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity>       <!--   <meta-data         android:name="com.google.android.maps.v2.api_key"         android:value="aizasybdub-4costeeh3xqvqhwzxl2bt0aam2h8"/>          -->           <meta-data         android:name="com.google.android.maps.v2.api_key"         android:value="aizasydilovjfmlkezki5ijtl0fka-qapscd_pk"/>     </application>  </manifest> 

if manifest file correct try man

activity_main.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" >  <fragment     android:name="com.google.android.gms.maps.supportmapfragment"     xmlns:map="http://schemas.android.com/apk/res-auto"     android:id="@+id/map"     android:layout_width="match_parent"     android:layout_height="match_parent"     map:cameratargetlat="33.41662287712097"     map:cameratargetlng="35.21843892856462"     map:camerazoom="4"/>  </linearlayout> 

in mainactivity.java oncreate()

public class mainactivity extends fragmentactivity  {  private googlemap mmap;  @override protected void oncreate(bundle savedinstancestate) {      super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      supportmapfragment mapfragment = (supportmapfragment) getsupportfragmentmanager().findfragmentbyid(r.id.map);     googlemap mmap = mapfragment.getmap();      mmap.addmarker(new markeroptions()     .position(new latlng(35.21843892856462, 33.41662287712097))     .title("my office"));  } 

here result on phone
