| cd '"${TOP}"' |
| source build/envsetup.sh # Add "lunch" (and other utilities and variables) |
| # to the shell environment. |
| lunch [<product>-<variant>] # Choose the device to target. |
| m -j [<goals>] # Execute the configured build. |
| |
| Usage of "m" imitates usage of the program "make". |
| See '"${SCRIPT_DIR}"'/Usage.txt for more info about build usage and concepts. |
| |
| Common goals are: |
| |
| clean (aka clobber) equivalent to rm -rf out/ |
| checkbuild Build every module defined in the source tree |
| droid Default target |
| 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" |

| 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. |
