本文介绍如何通过Remote-GDB工具进行Android代码调试。在两个不同的终端分别运行模拟器及调试器，设置监听端口为1234，并连接到指定的内核映像。使用Sourcery CodeBench Lite 2011.09版本的GDB工具读取vmlinux文件。

使用remote-gdb调试android代码：

在一个终端上：

./emulator -show-kernel -kernel zImage -qemu -cpu cortex-a8 -d in_asm -gdb tcp::1234 -S

另一个终端：

alloc@linux-q1tz:~/skyeye/armv7/armv7_goldfish_testcase> ~/CodeSourcery/Sourcery_CodeBench_Lite_for_ARM_GNU_Linux/bin/arm-none-linux-gnueabi-gdb vmlinux
