Android O module build toooo slow

[oliver wang]

I generally use "mm" command to issue a module make for a native Android module in Android Pre N release, it generally takes around seconds.

Android N also takes around seconds if use "mm USE_NINJA=false". However, O release takes several minutes for a module remake after I issue a "mm" or  "mm USE_NINJA=false" command.

Are there anyone facing the same problem?

Thanks,

Oliver

I have the same problem. On Nougat where a build of a previously built module (so there's no work to do) takes 2 seconds, on Nougat it 22 (twenty-two).
