Android 带有搜索按钮的谷歌地图Api

嗨，我正在尝试在android中实现GoogleAPI。我显示了地图。现在我想用2个用户给定地址的路由实现同样的功能。首先，我尝试用一个文本框和一个按钮来显示。我在logcat中发现以下错误：

谁能给我一个解决办法？我对Android很陌生，觉得有点难。

你在Emulator中试过这个吗？是的，我只在Emulator中试过。我也在安卓设备上试过，但它说，“不幸的是你的应用程序已经停止了”，你需要更新你的play services库，tryI应该在我的安卓设备上更新吗？在logcat中，它还显示了nullpointerexception？我尝试了最新的google play服务。我收到与“不幸的是，你的应用程序已停止”相同的错误消息
