Question

我在kitkat和jellybean上找不到类错误。我在软糖，kitkat模拟器，棒棒糖和marshmellow物理设备上测试了我的应用程序。

我搜索了很多帖子，但所有帖子都显示卸载和清除，或使用play-service-maps代替play-service。但是我需要使用play-services因为标记和所有东西。 请帮我解决这个问题。

这是我的 app＆gt; gradle

Answer 1

在build.gradle

上更改此设置

compile 'com.google.android.gms:play-services:10.0.1'

为此：

compile 'com.google.android.gms:play-services-maps:10.0.1'
compile 'com.google.android.gms:play-services-location:10.0.1'
compile 'com.google.android.gms:play-services-places:10.0.1'

请注意，the documentation建议仅使用必要的Play服务模块，而不是依赖于整个Play服务库：

如果您的应用中方法引用的数量超过65K限制，您的应用可能无法编译。通过仅指定应用使用的特定Google Play服务API而非全部API，您可以在编译应用时缓解此问题。有关如何执行此操作的信息，请参阅将API选择性地编译到可执行文件中。
