How to build AOSP app?

Question

I am trying to build the Camera App from AOSP.

I am on UBUNTU 14.04.

I followed the guide in the official documentation. At the end I execute

mak         


        

Answer 1

I believe you first need to set up your build environment by calling:

##> source build/envsetup.sh
##> launche <your-device-config>

Only then, call the make command to build the Camera:

make Camera -j8

your device should be one of the device configurations, for example "hammerhead" is for Nexus5

Answer 2

'make camera2' will build all the dependencies and then the actual camera2 app, which will be placed somewhere in out/, depending on your selected lunch target.

Once you've built it once to get the dependencies, mmm packages/apps/Camera2 will be a fast incremental compile, but it doesn't on its own build the dependencies.

Answer 3

You have 2 camera apps. The old version is called LegacyCamera and the newer version Camera2. You don't need to run make in order to compile them. You can just run

'mmm packages/apps/Camera2'

OR

'mmm packages/apps/LegacyCamera'
