我正在尝试调试 SipDemo SDK 示例。但是，DDMS 无法连接到模拟器上运行的应用程序（Android 4.0 API 级别 14）。模拟器等待调试，eclipse调试器无法打开端口。此外，ddms 报告 VM 调试端口无法打开。
确认以下，
- 端口未被使用
- ADB Server/Eclipse/Machine 已重新启动
- 主机文件检查 127.0.0.1
- 检查首选项以选择 127.0.0.1 作为 ADBHOST
- 为 Android 4.0 选择了合适的 VM
- 使用 Comodo 防火墙，所以在禁用防火墙后尝试调试。
应用程序期望的端口与调试器正在使用的端口存在差异。一个用于 Android 操作系统，一个用于运行 IDE 的实际主机？
