1# Debugging in DevEco Studio 2 3 4DevEco Studio provides a wide range of debugging features, which can be used to detect and rectify program errors during NDK development. These debugging features include: 5 6 7- Debugging using a real device: Run your application or service on a real device to see how it behaves on the device. 8 During debugging, if the source code path of the .so file of the local compilation device is different from the configured C++ source code path, fix the issue using either of the following methods: 9 10 - Create the mapping between files.<br>After you debug code with the Step Into feature, you will be prompted to associate the source code. Click **Select file** and select the local C++ source code for association. 11  12 - Create the mapping between paths.<br>Choose **Run** > **Edit Configurations**, select a module, switch to the **Debugger** tab, select **Native**, and add the **settings set target.source-map "/buildbot/path" "/my/path"** command on the **LLDB Startup Commands** tab page to establish the mapping. Parameter 1 indicates the source code path in the compilation environment, and parameter 2 indicates the local source code path. 13  14 15- Visualized variable debugging: Observe the continuous change of variable values on the GUI. By viewing, comparing, and analyzing the change process and logical relationship of a variable, you can determine whether the current value (variable) meets the expected result and locate the fault (if any) quickly and effectively. 16 17- C/C++ reverse debugging: During debugging, you can roll back to historical lines and breakpoints to view related variable information. 18
