[android-building] Clean Android 9 AOSP builds not finding Phone Sim on Pixel

2018-10-10 Thread Doug Swalen
I'm assuming this isn't actually a bug but something I need to address with 
the build process...

I've been doing some tests with clean unmodified AOSP builds on the Pixel. 
I had been working with Android 8 and 8.1 and my build process was as 
follows:

1. Clone the AOSP branch I want to build.
2. Download the corresponding Vendor and drivers files for that branch and 
copy them to the folder containing that branch.
3. source build/envsetup.sh
4. lunch  (select the Sailfish option)
5. make

I would then flash the binaries to the Pixel. The Pixel, which was not an 
OEM locked Pixel, had a phone sim in it and it worked.

But when I switched to Android 9, the sim was no longer being detected. I 
first noticed this with the 9.0.0_r2 branch. Yesterday I checked out and 
build the r10 branch and it's still an issue. AOSP isn't finding the Sim on 
the Pixel with Android 9.

Nothing changed in the build process. I'm following the same steps I did 
with 8.0 and 8.1 but now with 9.0 instead of a working Sim I get no Sim.

Can anyone offer any guidance on what I can do from the build side to 
address this. I hope this isn't actually a bug but something I'm failing to 
address...(though I can't see why things would need to change between 
8.0/8.1 and 9.0).

Thanks in advance...

Re: [android-building] can different Android branch code use the same ccache dir?

Yes, you should be able to share them across branches. We used to do this
on our builders, but we removed ccache from our builders (and master),
since it was causing more problems than it was saving in time. Incremental
builds are a bigger win (they've been increasingly safe with newer
versions, at least when paired with `m installclean`).

[android-building] can different Android branch code use the same ccache dir?

2018-10-10 Thread Minghui Ma
can different Android branch code  use the same ccache dir?
such as android n,o,p use the  same ccache dir path。
