我想调试一个SipDemo SDK示例。但是，DDMS无法挂接到仿真器上运行的应用程序（Android 4.0 API Level 14）。模拟器等待调试，并且eclipse调试器无法打开端口。另外，ddms报告VM调试端口无法打开。Android 4.0调试问题 - DDMS错误？
确认下列，
- 没有被使用的端口
- ADB服务器/ Eclipse中/机重新启动
- 主机文件检查127.0.0.1
- 首签选择127.0。 0.1作为ADBHOST
- 选择适合Android 4.0的VM
- 使用Comodo防火墙，因此在disab之后尝试调试关闭防火墙。
应用程序期望的端口和调试器正在使用的端口存在差异。是一个用于Android操作系统，一个用于运行IDE的实际主机？
