Difficulties we faced

  • Building some components needs multiple upstream repos

○ “android.jar” needs 4 repos

Difficulties we faced

  • Building some components needs multiple upstream repos

○ “android.jar” needs 4 repos

  • No usable build system

○ Handwritten Makefile according to “Android.mk” ○ Perhaps “Android.mk” can be interpreted
