I've been trying on many solution, finally I've come to my own fix. The solution goes as below.
我一直在尝试许多解决方案，最后我找到了自己的解决方案。解决方法如下。
Change your VM values in "\eclipse\eclipse.ini" as below:
openFile
--launcher.XXMaxPermSize
512M
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms512m
-Xmx1024mFollow https://developer.android.com/google/play-services/setup.htmlto set up and reference the "google-play-services_lib" into your project. Final output should be something like the image below:

-Dosgi.requiredJavaVersion=1.5
-Xms512m
-Xmx1024m按照https://developer.android.com/google/play-services/setup.html设置并将“google-play-services_lib”引用到您的项目中。最终输出应类似于下图：
- Add "google-play-services.jar" from "google-play-services_lib/libs" (according to step 2, after you imported the project into your workspace) into your build path as picture below:
- 将“google-play-services_lib/libs”中的“google-play-services.jar”（根据第2步，将项目导入工作区后）添加到构建路径中，如下图：
- Finally, check "google-play-services.jar" in "Order and Export" tab of Java Build Path:
- 最后，在 Java Build Path 的“Order and Export”选项卡中检查“google-play-services.jar”：
I hope this solution could help fellow android dev, as it got me frustrated since I followed the guide from google, but the app keep crashing :D
我希望这个解决方案可以帮助 android 开发人员，因为它让我很沮丧，因为我遵循了谷歌的指南，但应用程序不断崩溃：D

Check to see if your device has the Google Play Services app installed and also it has the same version as installed in your project.
检查您的设备是否安装了 Google Play 服务应用程序，并且它是否与您的项目中安装的版本相同。
Also check the minSDK and TargetSDK in the manifest file does not exceed or precede API levels.
还要检查清单文件中的 minSDK 和 TargetSDK 没有超过或先于 API 级别。
Do not miss this tag in Manifest:
不要错过 Manifest 中的这个标签：
<application
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
</application>

To test Google Play Services you'll need to be running on a physical device with Google Play Services installed.
要测试 Google Play 服务，您需要在安装了 Google Play 服务的物理设备上运行。
