地图Android版V2：java.lang.NoClassDefFoundError的：com.google.android.gms.R $设置样式

由于很多，我得到了以下错误： java.lang.NoClassDefFoundError的：试图执行为Android V2地图时com.google.android.gms.R $设置样式。

As many I get the following error: java.lang.noclassdeffounderror: com.google.android.gms.R$styleable when trying to implement Maps for Android V2.

不知怎的，我必须失去了什么，我究竟做错了，因为它不工作。我第一次尝试是对谷歌播放-services.lib复制到lib文件夹，但我看到的地方我不应该这样做。

Somehow I must be missing what I exactly am doing wrong, since it's not working. What I tried first is to copy the google-play-services.lib into the lib folder, but I saw somewhere I shouldn't do this.

然后我试图导入插件 - google_apis - 谷歌-8作为一个项目，但该项目给出了错误进口com.google不能得到解决。

Then I tried to import addon-google_apis-google-8 as a project, but the project gives the error The import com.google cannot be resolved.

我继 Vogella教程：

活动：

SupportMapFragment fm = (SupportMapFragment)   getSupportFragmentManager().findFragmentById(R.id.map);
        map = fm.getMap();

         //map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
                Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
                    .title("Hamburg"));
                Marker kiel = map.addMarker(new MarkerOptions()
                    .position(KIEL)
                    .title("Kiel")
                    .snippet("Kiel is cool")
                    .icon(BitmapDescriptorFactory
                        .fromResource(R.drawable.btn_logo)));

                // Move the camera instantly to hamburg with a zoom of 15.
                map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

                // Zoom in, animating the camera.
                map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);

清单：

    </application>

我通过输入通过安装密钥工具插件..的 http://keytool.sourceforge.net/update 指纹; com.testmap.test在谷歌控制台

I retrieved a_real_api_key by entering the SHA1 retrieved by installing the keytool plugin.. http://keytool.sourceforge.net/update fingerprint;com.testmap.test in the google console.

和XML：

 <fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment" />

我有我需要导入谷歌播放服务库的感觉，能有人告诉我一步一步如何在Eclipse中做到这一点，我已经跟着很多答案，但我似乎做的每一次有些不妥。

I have the feeling I need to import the google-play-services library, can somebody tell me step by step how to do this in Eclipse, I've followed many answers, but I seem to do something wrong every time.
