 1 | A Script for Building WebRTC Android Static Library. (Linux Only)
 2 | ========================
 3 | 
 4 | ### Getting the Code
 5 | 
 6 | [Refer to This Page](https://webrtc.googlesource.com/src/+/refs/heads/master/docs/native-code/index.md)
 7 | 
 8 | ### Build the Static Library
 9 | 
10 | Go to the source code root directory, and run this script. For example, build the APM:
11 | ```
12 | sh build_webrtc_android_static_lib.sh audio_processing
13 | ```
14 | 
15 | ### Use the libs
16 | It will generate the libs and the header files under the 'out' directory.
