9message='The basic Android build process is:
10
11cd '"${TOP}"'
12source build/envsetup.sh # Add "lunch" (and other utilities and variables)
13 # to the shell environment.
14lunch [<product>-<variant>] # Choose the device to target.
15m -j [<goals>] # Execute the configured build.
16
17Usage of "m" imitates usage of the program "make".
18See '"${SCRIPT_DIR}"'/README.txt for more info about build usage and concepts.
19
20Common 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
36
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
43So, for example, you could run:
44
45cd '"${TOP}"'
46source build/envsetup.sh
47lunch aosp_arm-userdebug
48m -j java
49
50to build all of the java code for the userdebug variant of the aosp_arm device.
