我在eclipse中为API 15-21创建了一个Android应用程序项目.

我导入了appCompat v7,cardView和recyclerView的库,但是在我的XML中添加了recyclelerView,它给android.support.v7.widget.RecyclerView无法实例化.

我有最新的SDK和更新的库.

我刚刚设置了一个onClick方法,该方法写在activity类中,只要单击该按钮就会被调用.即使在它进入方法之前,应用程序崩溃了.

单击浮动操作按钮时出现的错误消息;

我刚刚开始开发一个由移动应用程序使用的REST Web服务.Web服务使用Java开发,并在Apache服务器上运行.

我现在正转向测试部分.为此,我需要在真实服务器中托管我的Web服务.这是第一次体验,我只知道使用共享(共享)托管不允许我以任何语言托管任何应用程序.

我使用的是OVH,它不支持java Web服务托管.

有没有人提供任何其他选择.这会有很大帮助!!
