I build current AOSP project as the follows:
cd $android_aosp_dir
source build/envsetup.sh
lunch aosp_arm64-eng
After about an hour, it finished and said: build success..
But, I got an waring:
Created filesystem with 2639/163840 inodes and 268495/655360 blocks
WARNING: out/target/product/generic_arm64/system.img approaching size limit (2684354560 now; limit 2684354560)
Is that mains the system.img is not complete? and why the image is 2G large?
