Setup Android Environment

[Philipp Neumann]

Hello there,

I'm trying to setup build environment for building cobalt for android.

I've followed the steps here: https://developers.google.com/youtube/cobalt/docs/development/setup-android

In the lasts steps building crashpad handler the compiler fails with these and more:

I've used a ubuntu:20.04 docker container and took all the requirements steps mentioned in the tutorial. Any idea what I missed?

Kind regards

Hi Philipp,

Thanks for pointing that out, there may be missing a requirement in the instructions.
If you do `apt install g++-multilib` ( as in the CI container ) does that resolve the missing header problem ?
