• Cronet android

编译 android 库(Ubuntu 18.04)：https://chromium.googlesource.com/chromium/src/+/refs/heads/master/docs/android_build_instructions.md

android 开发文档 https://developer.android.com/guide/topics/connectivity/cronet

android 示例代码 https://chromium.googlesource.com/chromium/src/+/refs/heads/master/components/cronet/android

https://github.com/GoogleChromeLabs/cronet-sample/

#Ubuntu 18.04
mkdir chromium_android && cd chromium_android
nohup fetch --nohooks android & 	
cd src
echo "target_os = [ 'android' ]" >> ../.gclient	
gclient sync   #(This is the only difference between fetch android and fetch chromium.)

  2.1 
   $ ./components/cronet/tools/cr_cronet.py gn --release
  2.2 #you can run gn args {out_dir} and modify arguments in the editor that comes up.	
  	$gn args out/Release  #会修改 out/Release/args.gn
