No, even if the host does have python2, we'll be using our prebuilt instead. (Unless someone is explicitly calling /usr/bin/python[2], which would be a bug) As far as I know, AOSP uses host python to build and uses the prebuilt > version to do some testing The Soong python support (for host tools/tests and device tests) uses the python source in external/python/..., not the prebuilt. (The prebuilt is generated from the same sources) Will you change soong_ui to set AOSP build with prebuilt python2? > That already happened with Android 10 (Q). - Dan On Tue, Jan 21, 2020 at 8:23 AM XING WANG <[email protected]> wrote: > Thanks Dan, > > Please let me clarify further. > > So AOSP will not modify all python2 in the build script to be python3 > compatible(like dict.iteritems), and we should build AOSP with python2, If > the host does not have python2(20.04), we can use AOSP prebuilt python2. > > As far as I know, AOSP uses host python to build and uses the prebuilt > version to do some testing > Will you change soong_ui to set AOSP build with prebuilt python2? > > > On Tuesday, January 21, 2020 at 3:24:12 PM UTC+8, Dan Willemsen wrote: >> >> There are no current plans to switch everything over to python3.
