libnative_camera compilation

I am trying to build libnative_camera*.so locally on my own machine because the info-level logs in modules/androidcamera/camera_wrapper/camera_wrapper.cpp pollutes logcat.

I guess some of us might be interested in seeing the FPS during initial tests, but in a production build this turns out to be a problem. I have tried using cmake_android_all_camera.py to compile these but I am unable to build these libraries on my own computer.

I am using Ubuntu 12.04 (in a virtual machine), and have done: export ANDROID_STUB_ROOT=~/android_sources/

which is where I have the source code for Android downloaded from https://android.googlesource.com/

Does anyone know how I can go about building these libraries from scratch, or perhaps where I could get libnative_camera_*.so without the "LOGI("### Camera FPS ### [%d] Frames, %.2f FPS", mFrameCount, mFps);"?

Thanks, Arvind

Small tip, look at platforms/scripts/camera_build.conf. This is list scv table with path to Android sources, architecture and so on. To build native camera libs for all Android versions you need to have sources for all Androids. I believe, you need native camera lib for one Android version only. In this case open cmake_android_all_camera.py file with text editor, find command line for cmake and make and use them directly without python. This script with csv table were implemented for build automation of all native_camera_xxx libs. It is not usefull in your case.

Hey,

I'm also trying to build a libnative_camera library. What exactly is this bin_arm (or bin_x86 or bin_mips) directory that the build script needs? It is expected to be at the root directory of Android source. A fresh checkout of Android seems to be missing the bin_* directory.

Thanks.

It is folder with libraries libbinder.so, libutils.so, etc for each platform.
