根据许多教程，这是我在运行ndk-gdb后得到的结果。当它链接到(gdb)服务器时，您必须键入continue，但之后如何调试代码。在我的情况下，它显示Continuing并保持原样。无论我要做什么，我都毫无头绪。

Continuing.
如何调试？
根据ndk-Docs
You can set breakpoints with 'b <location>' and resume execution with 'c'
(for 'continue'). See the GDB manual for a list of commands.
如何实现这一点。
命令与gdb中的命令相同。基础引物：
- 通过输入
b <function name>或b <file>:<line number>设置断点 - 键入
s进入函数 - 键入
n转到下一行 - 使用
c继续执行 - 使用
print <exp>打印变量或表达式值 - 只需按enter键，即可重复上次键入的命令
你可以在网上找到更全面的gdb教程。我个人有一张gdb备忘单打印出来并贴在墙上。这应该足以让你开始。
本教程将向您展示如何在eclipse中使用ndk-gdb进行调试。
