Does ccache still works with newer AOSP?

[Eliane Fonseca]

I trying to use ccache with newer AOSP (9, 10) to attempt to speed up compiling time,but it looks like ccache is not being used even with the environment variables set. It is still possible to use ccache with AOSP 9 or 10? If not there are any alternatives and how I can use them ? Since my hardware is very underpowered (1 GHz CPU with auto-overclocking) I need to speed up the build time with the newer AOSP.

You have to provide your own ccache binary, then it should work (but I haven't tested it).

That being said, using ccache will actually slow down your builds, as it needs to do extra IO maintaining the cache. It really only helps if you're repeatedly doing clean rebuilds, in which case why aren't you using incremental builds? (It also only affects 1/3-1/2 of the build, as the rest of the actions are Java/etc)
