我们完全从命令行构建项目。已导入 Google Play Services 库项目：
android.library.reference.1=path/to/google-play-services_lib
所有不需要来自 GMS 的资源文件的 GMS 功能都可以正常工作（例如 LocationClient）。当我尝试提示用户更新 GMS 时，会出现以下错误：
E/AndroidRuntime( 3599): java.lang.NoClassDefFoundError: com.google.android.gms.R$string
E/AndroidRuntime( 3599): at com.google.android.gms.common.GooglePlayServicesUtil.b(Unknown Source)
E/AndroidRuntime( 3599): at com.google.android.gms.common.GooglePlayServicesUtil.a(Unknown Source)
E/AndroidRuntime( 3599): at com.google.android.gms.common.GooglePlayServicesUtil.getErrorDialog(Unknown Source)
取消索引 final classes.dex 表明所有字符串都在那里：
