maps - java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable in android -

i tried demo on displaying google maps v2 in android.

the java code is,

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

the xml code is,

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" >  <fragment        android:id="@+id/map"       android:layout_width="match_parent"       android:layout_height="match_parent"       android:name="com.google.android.gms.maps.mapfragment"/> </linearlayout> 

i added api key in manifest.xml,

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.gpslocator" android:versioncode="1" android:versionname="1.0" >  <uses-sdk     android:minsdkversion="3"     android:targetsdkversion="17" />  <uses-permission android:name="android.permission.internet" /> <uses-permission android:name="android.permission.access_network_state" /> <uses-permission android:name="android.permission.write_external_storage" /> <uses-permission android:name="com.google.android.providers.gsf.permission.read_gservices" /> <!--  following 2 permissions not required use  google maps android api v2, recommended. --> <uses-permission android:name="android.permission.access_coarse_location" /> <uses-permission android:name="android.permission.access_fine_location" />  <permission     android:name="com.example.mapdemo.permission.maps_receive"     android:protectionlevel="signature" />  <uses-permission android:name="com.example.mapdemo.permission.maps_receive" />  <uses-feature     android:glesversion="0x00020000"     android:required="true" />  <application     android:icon="@drawable/ic_launcher"     android:label="@string/app_name"     android:theme="@style/apptheme" >     <activity         android:name="com.example.gpslocator.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="my_api_key" /> </application>  </manifest> 

when tried run application closes of suddenly. when debug, showed me error, "java.lang.noclassdeffounderror: com.google.android.gms.r$styleable". added google-play-services.jar file application.

the logcat is,

please 1 me out. missing reference?

see answer here:
google maps android api v2 - sample code crashes
while question lists different exception, answer mentions exact problem.

specifically, it's important import google-play-services_lib project:
select file > import > android > existing android code workspace , click next.
select browse..., enter [android-sdk-folder]/extras/google/google_play_services/libproject/google-play-services_lib, , click finish.
(see https://developers.google.com/maps/documentation/android/intro under "sample code")
follow instructions linked answer:

• import actual source "google-play-services_lib" project , link >android library.
  • do through project -> properties -> android -> library, add -> google-play-services_lib (you can right click on project , choose properties, select android).
  • do not add dependent project through "java build path" project, didn't work me.
