791    <p class="fontColor">符号表导入适用于所有支持调用栈的 Tab 页,创建文件夹,然后将需要导入的so文件放进文件夹内,在导入时,选择该文件夹即可,这样,系统将会获取到该文件夹内所有的so文件,更新数据库中符号数据。文件夹内 so 的格式需要与在设备上的路径一致,例如下图中,选择的文件夹为 import,选择导入的 libnative_hook.z.so,在设备上的路径是/system/lib64/,那么在本地选择的文件夹内也需要保证路径是 import/system/lib64/libnative_hook.z.so。<br>
792      <img src="../figures/OperationSkills/Operation_soimport_dir.jpg" alt="GitHub Logo"><br>
793      以 NativeMemory 举例,导入 NativeMemory 文件,点击 Call info 的 Tab 页,在搜索框中输入 libnative_hook.z.so,会发现该 so 下的调用栈没有符号化完全。<br>
794      <img src="../figures/OperationSkills/Operation_soimport_nativehook.jpg" alt="GitHub Logo"><br>
795      将本地编译的 so 通过导入按钮导入,本地导入路径是 import/system/lib64/libnative_hook.z.so,红框处是导入按钮。<br>
796      <img src="../figures/OperationSkills/Operation_soimport_local.jpg" alt="GitHub Logo"><br>
797      导入 so 以后,在搜索框中输入 libnative_hook.z.so,会发现符号化数据已经更新。<br>

892    <p class="fontColor">在界面的如下入口可以导入分布式文件,将两个文件放到文件夹下,以文件夹的形式导入。<br>

896      分布式Trace导入完成后,在泳道界面通过点击节点slice数据(分布式),会构建同进程(线程)或跨进程(线程)、单trace或多trace间的折线。折线绘制规则是:同一调用链,相邻数据的spanId相同或者当前spanId和另一个数据的parentSpanId相同时绘制关联关系的折线。<br>
