推荐答案
此错误通常意味着您已尝试多次将同一类中的链接链接到您的项目，这是不允许的.有问题的类是 com/google/android/gms/actions/ReserveIntents，它位于 Google Play 服务库中.
This error in general means that you've tried to link in the same class to your project more than once, which isn't allowed. The offending class is com/google/android/gms/actions/ReserveIntents, which is in the Google Play Services library.
问题在于您的依赖项:
compile 'com.google.android.gms:play-services:6.5.87'
compile 'com.google.android.gms:play-services-maps:6.5.+'
这些都是多余的.play-services:6.5.87 包含所有内容，如果您拥有它，则不需要 play-services-maps:6.5.+ 依赖项.您可能想要后者的原因是，如果您的项目太大，而您需要缩减为更小、更精细的 Play 服务，其中您只包含您需要的内容.
These are redundant. The play-services:6.5.87 includes everything, and if you have that, you don't need the play-services-maps:6.5.+ dependency. The reason you might want the latter one is if your project gets too big and you need to pare down to a smaller, more granular Play Services where you only include what you need.
为了让生活更轻松，我建议使用第一个，如果您遇到编译问题(例如最经典的问题，无法执行 dex:方法 ID 不在 [0, 0xffff] 中:65536，尽管它采用不同的形式), 那么就可以转为后一种格式了.
To make life easier, I'd recommend going with the first one, and if you run into compile problems (such as the most classic one, Unable to execute dex: method ID not in [0, 0xffff]: 65536, though it takes different forms), then you can go to the latter format.
