假设你正在使用AS和摇篮为构建脚本/依赖管理

要导入谷歌Play服务，您正在使用的依赖全是这样的：

compile 'com.google.android.gms:play-services:7.8.0' 

，其中包括所有的服务资源，类，这是巨大的名单：

+--- com.google.android.gms:play-services:7.8.0 
| +--- com.google.android.gms:play-services-ads:7.8.0 
| | +--- com.google.android.gms:play-services-base:7.8.0

| \--- com.google.android.gms:play-services-wearable:7.8.0 
|   \--- com.google.android.gms:play-services-base:7.8.0 (*) 

要缩小，你有三种选择：

• 仅添加它的一部分，你需要，例如。 com.google.android.gms:play-services-maps:7.8.0
• 排除部分你不想

这样的：

compile('com.google.android.gms:play-services:7.8.0') { 
    exclude module: 'play-services-fitness' 
    exclude module: 'play-services-games' 
    exclude module: 'play-services-wallet' 
    exclude module: 'play-services-safetynet' 
    exclude module: 'play-services-appinvite' 
    exclude module: 'play-services-wearable' 
    exclude module: 'play-services-cast' 
} 

• 或者使用Proguard的（minifyEnabled），这应该从产生的APK资源和类，不属于修剪使用或者改为
