收到错误java.lang.NoClassDefFoundError的：com.google.android.gms.common.GooglePlayServicesUtil

我知道it'a已经有很多的问题是这样的，我读了所有的人，反正不能找到解决办法。我做了什么：

I know it'a already many questions was like this, I read all of them, and can't find solution anyway. What i did:

我没有这一切几步 http://developer.android罚款.COM /谷歌/播放服务/ setup.html＃安装安装谷歌玩SDK
在Android的标签我的项目属性我有谷歌发挥服务库好了，用Java构建路径：Android的私家藏书我有谷歌，播放service.jar中，而这个库被选中。我做了导入库项目也。

I did all this steps fine from http://developer.android.com/google/play-services/setup.html#Install to install google play sdk In my project property in Android tab I have "google play service library" ok, in Java Builder Path: "Android Private Libraries" i have google-play-service.jar, and this library are selected. I did Import lib project also.

code测试我从 http://developer.android.com了/google/gcm/client.html 。
我的清单文件：
    
    

Code for testing i took from http://developer.android.com/google/gcm/client.html. My manifest file:

我的Java code：
包lt.vaziouju.vaziuoju;

My java code: package lt.vaziouju.vaziuoju;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;

public class Test_GCM extends Activity {

private static final String TAG = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_test__gcm);

    TextView mDisplay = (TextView) findViewById(R.id.display);

    Context context = getApplicationContext();

    // Check device for Play Services APK.
    if (checkPlayServices()) {
        // If this check succeeds, proceed with normal processing.
        // Otherwise, prompt user to get valid Play Services APK.
    }
}

// You need to do the Play Services APK check here too.
@Override
protected void onResume() {
    super.onResume();
    checkPlayServices();
}

/**
 * Check the device to make sure it has the Google Play Services APK. If
 * it doesn't, display a dialog that allows users to download the APK from
 * the Google Play Store or enable it in the device's system settings.
 */


private boolean checkPlayServices() {
    int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
    if (resultCode != ConnectionResult.SUCCESS) {
        if (GooglePlayServicesUtil.isUserRecoverableError(resultCode)) {
            GooglePlayServicesUtil.getErrorDialog(resultCode, this, PLAY_SERVICES_RESOLUTION_REQUEST).show();
        } else {
            Log.i(TAG, "This device is not supported.");
            finish();
        }
        return false;
    }
    return true;
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.test__gcm, menu);
    return true;
}

}

如果您有任何想法，我怎么能，这将是炉排。我知道我不够好于机器人编程，刚开始学习GCM，但我已经花6小时来阅读一个谷歌，并没有什么。

If you have any idea how I can it, it will be grate. I know I'm not good enough in android programming, and just started learning GCM but I'm already spend 6h to reading a google, and nothing.

感谢您的任何想法。
