Build not picking up changes in Android.bp

[Donal Morrissey]

Hi There,

This is my setup:

• AOSP branch: android-9.0.0_r46
• Target: generic_x86_64

I'm currently working on an Android example HIDL interface, with accompanying client and server processes. These are all created in a new vendor directory structure at the top level of the repo checkout.:

vendor/

└── horizonemb

    ├── clients

    │   └── example_client

    │       ├── Android.bp

    │       └── exampleClient.cpp

    └── interfaces

        ├── Android.bp

        └── example

            └── 1.0

                ├── Android.bp

                ├── default

                │   ├── Android.bp

                │   ├── Example.cpp

                │   ├── Example.h

                │   ├── service.cpp

                │   └── vendor.horizonemb...@1.0-service.rc

                └── IExample.hal

If I change the VNDK related properties (vendor_available, etc) in any of my Android.bp files, their installation destination (/vendor v's /system) does not change when I build with the 'm' command. I have to first delete the out directory and then carry out a full build.

After modifying an Android.bp file, is there some other command I need to run before I build with the 'm' command?

Thank you,

Donal

No, there's nothing you need to do. vendor_available defines two installations -- one into the vendor partition and one into the system partition. To trigger the installation of the vendor version, you may need to specify `m <modulename>.vendor` instead of `m <modulename>`

If you don't need both copies of the module, use `vendor: true` instead of vendor_available. You may still need the .vendor on the command line, I don't remember.
