这个错误在你已经尝试在同一类链接到你的项目超过一次，这是不允许的通用方法。违规课程是com/google/android/gms/actions/ReserveIntents，位于Google Play服务库中。

的问题是在你的依赖：

compile 'com.google.android.gms:play-services:6.5.87' 
compile 'com.google.android.gms:play-services-maps:6.5.+'

这些是多余的。 play-services:6.5.87包含了所有内容，如果有的话，则不需要play-services-maps:6.5.+依赖关系。你可能想要后者的原因是，如果你的项目变得太大，你需要削减到一个更小，更细化的播放服务，你只需要包括你所需要的。

为了让生活更轻松，我建议你先用第一种方法，如果遇到编译问题（比如最经典的，Unable to execute dex: method ID not in [0, 0xffff]: 65536，尽管它采用不同的形式），那么你可以去后者格式。

看来你有一个jar文件或出现多次LIB更多的文档。因此，从lib文件夹中删除.jar文件生成>重建必须工作。
