Generate framework compatibility matrix from fqnames

README.md

Generate framework compatibility matrix from fqnames

• Download these 2 files
• Compile AOSP without fcm from stock and wait for check_vintf to error out
• Delete Python prefix from all lines (e.g. checkvintf E 06-24 00:30:22 49120 49120 check_vintf.cpp:554])
• Paste the result in fqnames.txt
• Launch the script

fqnames.txt

# Add here a list of fqname
# You can get it if you try to build AOSP without a fcm
# check_vintf will print a list of needed entries
# This currently works with AIDL and HIDL
# Here an example from Xiaomi SM8150 common tree

Hey, it doesn't work when there is aidl type entry example: android.hardware.power.IPower/default (@2)

I try to adapt the code to support versioning aidl here
Feel free to test and suggest better code
