Replaced the files in the vendor/XXXX folder with the latest version and initiated a build(m -j8). It took less than 5 mins to complete the built.
New system images are created. However, changes are not updated in the emulator.
However things work when I delete the out folder and try the build again. That will take 3-4 hours to complete the build.
Anyone know the reason why it didn't work the first time.
