### Obtain SDK Source Code

* **Network Disk Directory**:

  ```
  ├── 1-SDK_Source_Code
  │   ├── android10.0
  │   └── ubuntu1604
  ```
* **Copy Source Code Archive to Compilation Host** (Linux environment):

  > **Notes**:
  >
  > 1. Do not place source code in shared directories for compilation.
  > 2. Do not use the **root account** to log into the compilation host.
* **Extract Source Code and Restore Git Directory**:

  > Replace `a133-*.tar.gz` with your actual source code archive.

  ```bash
  mkdir sdk
  tar -zxf a133-*.tar.gz -C sdk/
  cd sdk
  git reset --hard
  ```
