搭建Android(安卓)+ Eclipse环境时遇到的问题

近来要参与到一个Android项目中，因为之前没接触过Android，所以在搭建环境的过程中遇到了几个问题，在这里写写，供大家参考：

1、搭建环境时出现的问题参考：http://blog.csdn.net/sheshou2/article/details/6152988

错误信息提示

解决办法

错误信息提示

解决办法

查看任务管理器，关闭所有adb.exe，然后重启eclipse即可

2、模拟器问题

搭建好环境后，模拟器上的按键不能使，提示“DPAD not enabled AVD”，如图1所示

图1

解决办法是：Window——>AndroidVirtual Device Manager——>选项卡的Device Definitions页面——>选中一个Device，点击【Clone】按钮，自己设置数据，关键是要如图2那样设置Device。选中clone出来的Device——>点击按钮“Create AVD”，设置相应的参数即可！如图3所示。

3、出现的问题：

Failed to fectch URl https://dl-ssl.google.com/android/repository/addons_list.xml, reason: Connection to https://dl-ssl.google.com refused

解决办法：

用notepad打开C:\Windows\System32\drivers\etc中的hosts文件，在最后一行添加
