Troubleshoot
Android 11
 - sdk_car_ target is missing, fix is above
 - build succeeds, however emulator doesn't work

Android 12
 - ccache, read only:
   rm -rf /mnt/ccache
   mkdir /mnt/ccache
   mount --bind /root/.ccache /mnt/ccache

Reset changed files
  - repo forall -vc "git reset --hard"

could'nt locale source file: ....
  - then run the following code
    make split-select
    make libaapt2_jni
    m aapt dmtracedump etc1tool aapt2 aidl split-select zipalign llvm-rs-cc bcc_compat apksigner dx sdk sdk_repo

Proprietry files for gta4xlwifi
  - Extract script from existing image fails. So need to extract from the device first. Or use already extracted files as following:
    unzip gta4xl-common-proprietary.zip .
    mv proprietary /LINEAGE/device/samsung/gta4xl-common/
    unzip gta4xlwifi-proprietary.zip
    mv proprietary /LINEAGE/device/samsung/gta4xlwifi/
