本文介绍了解决GDBServer端口被占用的问题，包括调整端口号设置、检查后台进程并终止冲突进程的方法。

可能的原因1:VisualGDB Project Setting->Debug settings 改了端口号,保存

寻找原因:

对比project-Debug.vgdbsettings,红色为新增处

.....

  <GenerateCtrlBreakInsteadOfCtrlC>false</GenerateCtrlBreakInsteadOfCtrlC>
    <PreferredDevice />
    <UseDefaultInstallDir>false</UseDefaultInstallDir>
    <RemotePort>5038</RemotePort>
    <LocalPort>5038</LocalPort>

.....

<EnableThreadNameWatcher>true</EnableThreadNameWatcher>
    <LaunchAMStartParameters />
    <StartupActivity />
    <GDBServer />
    <StandaloneExeSettings>
      <DeploymentDirectory>/data/local/tmp</DeploymentDirectory>
      <WorkingDirectory />
      <CommandLineArguments />
      <Environment>
        <Records />
      </Environment>
    </StandaloneExeSettings>
</Debug>

.......

结果与解决方案:

结果测试发现问题在 <WorkingDirectory />.

修改为<WorkingDirectory>/data/local/tmp</WorkingDirectory>即可,也可通过VisualGDB Project Setting->Debug settings修改.

可能的原因2:工程中创建su后台进程 su --daemon&.

root 1971 1 1140 332 c0262d18 b6ec0110 S su

寻找原因:
