Step 1 :- Create New Android Project.

Step 2 :- Add Google-play-services_lib to your project.

Step 3 :- Open AndroidManifest.xml file.

<!--?xml version="1.0" encoding="utf-8"?-->
package="com.mapv2.demo"
android:versionCode="1"
android:versionName="1.0" &gt;

&lt;uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="16" /&gt;

&lt;permission
android:name="com.mapv2.demo.permission.MAPS_RECEIVE"
android:protectionLevel="signature"/&gt;

&nbsp;

&nbsp;

&lt;uses-feature
android:glEsVersion="0x00020000"
android:required="true"/&gt;

&lt;application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" &gt;
&lt;activity
android:name="com.mapv2.demo.MainActivity"
android:label="@string/app_name" &gt;
&nbsp;

&lt;meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyCmX7SLVHXxU9pSqb2QbAOvdnjAGUulOrk"/&gt;

&nbsp;

Step 4 :- Open activity_main.xml.

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<Spinner
android:id="@+id/spr_place_type"
android:layout_width="wrap_content"
android:layout_height="60dp"
android:layout_alignParentTop="true" />

<Button
android:id="@+id/btn_find"
android:layout_width="wrap_content"
android:layout_height="60dp"
android:layout_alignParentTop="true"
android:layout_toRightOf="@id/spr_place_type"
android:text="@string/str_btn_find" />

android:id="@+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/spr_place_type"
class="com.google.android.gms.maps.SupportMapFragment" />
