| 9 | message='The basic Android build process is: |
| 10 | |
| 11 | cd '"${TOP}"' |
| 12 | source build/envsetup.sh # Add "lunch" (and other utilities and variables) |
| 13 | # to the shell environment. |
| 14 | lunch [<product>-<variant>] # Choose the device to target. |
| 15 | m -j [<goals>] # Execute the configured build. |
| 16 | |
| 17 | Usage of "m" imitates usage of the program "make". |
| 18 | See '"${SCRIPT_DIR}"'/README.txt for more info about build usage and concepts. |

| 20 | Common goals are: |
| 21 | |
| 22 | clean (aka clobber) equivalent to rm -rf out/ |
| 23 | checkbuild Build every module defined in the source tree |
| 24 | droid Default target |
| 25 | nothing Do not build anything, just parse and validate the build structure |
| 26 | |
| 27 | java Build all the java code in the source tree |
| 28 | native Build all the native code in the source tree |
| 29 | |
| 30 | host Build all the host code (not to be run on a device) in the source tree |
| 31 | target Build all the target code (to be run on the device) in the source tree |
| 32 | |
| 33 | (java|native)-(host|target) |
| 34 | (host|target)-(java|native) |
| 35 | Build the intersection of the two given arguments |

| 37 | snod Quickly rebuild the system image from built packages |
| 38 | Stands for "System, NO Dependencies" |
| 39 | vnod Quickly rebuild the vendor image from built packages |
| 40 | Stands for "Vendor, NO Dependencies" |
| 41 | |
| 42 | |
| 43 | So, for example, you could run: |
| 44 | |
| 45 | cd '"${TOP}"' |
| 46 | source build/envsetup.sh |
| 47 | lunch aosp_arm-userdebug |
| 48 | m -j java |
| 49 | |
| 50 | to build all of the java code for the userdebug variant of the aosp_arm device. |
