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

I tried a 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 the menu; this adds items to the action bar if it is 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" /> <!-- The following two permissions are not required to use Google Maps Android API v2, but are 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 I tried to run my Application closes of suddenly. When I debug, It showed me the error, "java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable". I added google-play-services.jar file to my application. The logcat is, ``` 04-09 05:33:53.677: E/Trace(1053): error opening trace file: No such file or directory (2) 04-09 05:33:53.807: W/ActivityThread(1053): Application com.example.gpslocator is waiting for the debugger on port 8100... 04-09 05:33:53.878: I/System.out(1053): Sending WAIT chunk 04-09 05:33:54.207: I/dalvikvm(1053): Debugger is active 04-09 05:33:54.288: I/System.out(1053): Debugger has connected 04-09 05:33:54.288: I/System.out(1053): waiting for debugger to settle... 04-09 05:33:54.487: I/System.out(1053): waiting for debugger to settle... 04-09 05:33:54.697: I/System.out(1053): waiting for debugger to settle... 04-09 05:33:54.897: I/System.out(1053): waiting for debugger to settle... 04-09 05:33:55.097: I/System.out(1053): waiting for debugger to settle... 04-09 05:33:55.297: I/System.out(1053): waiting for debugger to settle... 04-09 05:33:55.498: I/System.out(1053): waiting for debugger to settle... 04-09 05:33:55.708: I/System.out(1053): waiting for debugger to settle... 04-09 05:33:55.907: I/System.out(1053): waiting for debugger to settle... 04-09 05:33:56.167: I/System.out(1053): waiting for debugger to settle... 04-09 05:33:56.367: I/System.out(1053): debugger has settled (1344) 04-09 05:34:06.097: W/dalvikvm(1053): VFY: unable to resolve static field 867 (MapAttrs) in Lcom/google/android/gms/R$styleable; 04-09 05:34:06.097: D/dalvikvm(1053): VFY: replacing opcode 0x62 at 0x000e 04-09 05:40:21.278: D/AndroidRuntime(1053): Shutting down VM 04-09 05:40:21.278: W/dalvikvm(1053): threadid=1: thread exiting with uncaught exception (group=0x40a71930) 04-09 05:40:21.398: E/AndroidRuntime(1053): FATAL EXCEPTION: main 04-09 05:40:21.398: E/AndroidRuntime(1053): java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable 04-09 05:40:21.398: E/AndroidRuntime(1053): at com.google.android.gms.maps.GoogleMapOptions.createFromAttributes(Unknown Source) 04-09 05:40:21.398: E/AndroidRuntime(1053): at com.google.android.gms.maps.MapFragment.onInflate(Unknown Source) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.app.Activity.onCreateView(Activity.java:4716) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:680) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.view.LayoutInflater.rInflate(LayoutInflater.java:746) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.view.LayoutInflater.inflate(LayoutInflater.java:489) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.view.LayoutInflater.inflate(LayoutInflater.java:396) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.view.LayoutInflater.inflate(LayoutInflater.java:352) 04-09 05:40:21.398: E/AndroidRuntime(1053): at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:270) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.app.Activity.setContentView(Activity.java:1881) 04-09 05:40:21.398: E/AndroidRuntime(1053): at com.example.gpslocator.MainActivity.onCreate(MainActivity.java:12) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.app.Activity.performCreate(Activity.java:5104) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1080) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2144) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2230) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.app.ActivityThread.access$600(ActivityThread.java:141) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1234) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.os.Handler.dispatchMessage(Handler.java:99) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.os.Looper.loop(Looper.java:137) 04-09 05:40:21.398: E/AndroidRuntime(1053): at android.app.ActivityThread.main(ActivityThread.java:5041) 04-09 05:40:21.398: E/AndroidRuntime(1053): at java.lang.reflect.Method.invokeNative(Native Method) 04-09 05:40:21.398: E/AndroidRuntime(1053): at java.lang.reflect.Method.invoke(Method.java:511) 04-09 05:40:21.398: E/AndroidRuntime(1053): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:793) 04-09 05:40:21.398: E/AndroidRuntime(1053): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:560) 04-09 05:40:21.398: E/AndroidRuntime(1053): at dalvik.system.NativeStart.main(Native Method) 04-09 05:40:26.487: I/Process(1053): Sending signal.
