sha256sum ~/bin/repo
chmod a+x ~/bin/repo
repo init -u https://android.googlesource.com/platform/manifest -b android-8.1.0_r72
repo sync
Updated build/envsetup.sh. Added this to end:
export LC_ALL=C
export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4g"
./prebuilts/sdk/tools/jack-admin kill-server
./prebuilts/sdk/tools/jack-admin start-server
(Fixes from https://stackoverflow.com/questions/51324238/aosp-build-stopped-subcommand-failed and https://stackoverflow.com/questions/35579646/android-source-code-compile-error-try-increasing-heap-size-with-java-option)
Sometimes Jack needs to be re-installed:
cd ./prebuilts/sdk/tools/
./jack-diagnose
./jack-admin install-server jack-launcher.jar jack-server-4.11.ALPHA.jar
source ./build/envsetup.sh
lunch aosp_arm64-eng
m droid
Cleaning up:
m clean
