'The basic Android build process is:
cd
'"${TOP}"'
source build/envsetup.sh
# Add "lunch" (and other utilities and variables)
# to the shell environment.
lunch [<product>-<variant>]
# Choose the device to target.
m [<goals>]
# Execute the configured build.
Usage of
"m" imitates usage of the program
"make".
See
'"${SCRIPT_DIR}"'/Usage.txt
for more info about build usage and concepts.
The parallelism of the build can be set with a -jN argument to
"m".
If you
don
'\''t provide a -j argument, the build system automatically selects a parallel
task count that it thinks is optimal
for your system.
Common goals are:
clean (aka clobber) equivalent to
rm -rf out/
checkbuild Build every module defined in the source tree
droid Default target
sync Build everything in the default target except the images,
for use with adb sync.
nothing
Do not build anything, just parse and validate the build structure
java Build
all the java code in the source tree
native Build
all the native code in the source tree
host Build
all the host code (not to be run on a device) in the source tree
target Build
all the target code (to be run on the device) in the source tree
(java|native)-(host|target)
(host|target)-(java|native)
Build the intersection of the two given arguments
snod Quickly rebuild the system image from built packages
Stands
for "System, NO Dependencies"
vnod Quickly rebuild the vendor image from built packages
Stands
for "Vendor, NO Dependencies"
pnod Quickly rebuild the product image from built packages
Stands
for "Product, NO Dependencies"
senod Quickly rebuild the system_ext image from built packages
Stands
for "SystemExt, NO Dependencies"
onod Quickly rebuild the odm image from built packages
Stands
for "Odm, NO Dependencies"
vdnod Quickly rebuild the vendor_dlkm image from built packages
Stands
for "VendorDlkm, NO Dependencies"
odnod Quickly rebuild the odm_dlkm image from built packages
Stands
for "OdmDlkm, NO Dependencies"
sdnod Quickly rebuild the system_dlkm image from built packages
Stands
for "SystemDlkm, NO Dependencies"
So,
for example, you could run:
cd
'"${TOP}"'
source build/envsetup.sh
lunch aosp_arm-userdebug
m -j java
to build
all of the java code
for the userdebug variant of the aosp_arm device.
