   Your environment is set up to build an AOSP image.  You'll need to specify a
   build target using the 'lunch' command.  The following targets are expected
   to work in this container and should be a good starting point for your
   project:

|------------------------|----------------------|-----------------------------|
| Machine                | Lunch Target         | Emulator                    |
|------------------------|----------------------|-----------------------------|
| AOSP Phonse on x86_64  | sdk_phone_x86_64     | Goldfish (QEMU backend)     |
| basic emulator         |                      |                             |
|------------------------|----------------------|-----------------------------|
| AOSP Phone on x86_64   | aosp_cf_x86_64_phone | Cuttlefish (QEMU or CrosVM) |
| advanced emulator      |                      |                             |
|------------------------|----------------------|-----------------------------|
| AOSP Automotive (AAOS) | aosp_cf_x86_auto     | Cuttlefish (QEMU or CrosVM) |
| x86 advanced emulator  |                      |                             |
|------------------------|----------------------|-----------------------------|
| AOSP on aarch64 QEMU   | fvp                  | Stock QEMU / ARM FVP        |
| with graphics          |                      |                             |
|------------------------|----------------------|-----------------------------|
| AOSP on aarch64 QEMU   | fvp_mini             | Stock QEMU / ARM FVP        |
| without graphics       |                      |                             |

   For example, to build a Goldfish Emulator image:

      $ lunch sdk_phone_x86_64

   Unable to locate an AOSP source tree in the expected location:

      BUILD_VOLUME/aosp13

   You may have started the container without a volume mapping for your Android
   source tree.  If so, you should restart the container including the following
   options on your 'docker run' command line or add an appropriate volume mapping
   entry to your Docker compose file:

      --mount type=bind,src=<path_to_aosp>,target=BUILD_VOLUME/aosp13

   If you have placed your source tree at a different location, you may access
   it from there and set up your build environment by sourcing the
   build/envsetup.sh script located in your aosp13 source tree.
