Currently it extracts from the provided jar file compat/compat_config.xml (generated by compat-changeid-annotation-processor) and installs on /system/etc/sysconfig. Future improvements: - Merge all the configs going for the system image into one, so that duplicate change ids across modules are failing the build instead of runtime. - Support uploading the config onto APEX for APEX modules. Test: flashed device locally, config files found and read by com.android.server.compat.CompatConfig. Bug: 138222363 Change-Id: I64b11fdc466f746702e7e73f612794e024de2288
