我正在尝试按照本教程http://www.androidhive.info/2015/04/android-getting-started-with-material-design/进行操作。当我到达第13步时我测试了应用程序并且它工作正常但是当我到达第23步导航抽屉时我遇到了一个问题
android.support.v7.widget.RecyclerView cannot be instantiated
在阅读其他网站关于此问题的评论后，我得出结论，我必须在预览面板上设置API级别22，但由于我的ADT与我不兼容，我尝试更新它（我的ADT），一切顺利，直到我已经达到了第23步，我现在尝试测试我的应用程序，如果它是基于本教程运行的话。让我感到沮丧的是ADT
unable to bind xxxx to DDMS
我尝试通过遵循各个站点（包括此站点）的其他说明再次修复错误。我从Windows主机文件中添加了127.0.0.1 localhost，因为除了它只是评论之外没有。我甚至尝试过使用cmd中的代码adb kill-server和adb start-server。我也去了window -> preference -> Android -> DDMS，在那里我尝试将值8601 on Base local debugger port和check the use ADBHOST添加到values 127.0.0.1。我一个接一个地做了每个人，但不幸的是错误仍然存在。
我面临的问题是应用程序无法启动或在bluestack上运行。我尝试运行我的其他应用程序项目，看看它们是否碰巧运行不好但似乎它们运行顺畅，没有错误或蓝图上崩溃所以我认为它与我正在关注的项目有关上面提到的教程，但我不知道如何弄明白，因为我的所有代码都很好，没有红色标记或错误，但他们只是有警告，这对我来说似乎没问题。
这是我的Manifest.xml（您可以在上面的教程中看到其余代码，直到第23步）
