Use shared lib of libtinyxml2 instead of static one.

libtinyxml2 is used commonly by vendors. So using its shared lib will reduce
total image size even though Android framework size increases as following for
now.

bluetooth.default.so: 1470356 -> 1440664 (-29692)
libtinyxml2.so      :       0 ->   46144 (+46144)
total               :                    (+16452)

Test: building succeeded, and the image was tested on angler.

Fluoride Bluetooth stack

Building and running on AOSP

Just build AOSP - Fluoride is there by default.

Building and running on Linux

Instructions for Ubuntu, tested on 14.04 with Clang 3.5.0 and 16.10 with Clang 3.8.0

Download source

mkdir ~/fluoride
cd ~/fluoride
git clone https://android.googlesource.com/platform/packages/modules/Bluetooth/system

Install dependencies (require sudo access):

cd ~/fluoride/bt
build/install_deps.sh

Then fetch third party dependencies:

cd ~/fluoride/bt
mkdir third_party
cd third_party
git clone https://github.com/google/googletest.git
git clone https://android.googlesource.com/platform/external/libchrome
git clone https://android.googlesource.com/platform/external/modp_b64
git clone https://android.googlesource.com/platform/external/tinyxml2
git clone https://android.googlesource.com/platform/hardware/libhardware

And third party dependencies of third party dependencies:

cd fluoride/bt/third_party/libchrome/base/third_party
mkdir valgrind
cd valgrind
curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/valgrind.h?format=TEXT | base64 -d > valgrind.h
curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/memcheck.h?format=TEXT | base64 -d > memcheck.h

NOTE: If packages/modules/Bluetooth/system is checked out under AOSP, then create symbolic links instead of downloading sources

cd packages/modules/Bluetooth/system
mkdir third_party
cd third_party
ln -s ../../../external/libchrome libchrome
ln -s ../../../external/modp_b64 modp_b64
ln -s ../../../external/tinyxml2 tinyxml2
ln -s ../../../hardware/libhardware libhardware
ln -s ../../../external/googletest googletest

Generate your build files

cd ~/fluoride/bt
gn gen out/Default

Build

cd ~/fluoride/bt
ninja -C out/Default all

This will build all targets (the shared library, executables, tests, etc) and put them in out/Default. To build an individual target, replace “all” with the target of your choice, e.g. ninja -C out/Default net_test_osi.

Run

cd ~/fluoride/bt/out/Default
LD_LIBRARY_PATH=./ ./bluetoothtbd -create-ipc-socket=fluoride

Eclipse IDE Support

  1. Follows the Chromium project Eclipse Setup Instructions until “Optional: Building inside Eclipse” section (don't do that section, we will set it up differently)

  2. Generate Eclipse settings:

cd packages/modules/Bluetooth/system
gn gen --ide=eclipse out/Default

  1. In Eclipse, do File->Import->C/C++->C/C++ Project Settings, choose the XML location under packages/modules/Bluetooth/system/out/Default

  2. Right click on the project. Go to Preferences->C/C++ Build->Builder Settings. Uncheck “Use default build command”, but instead using “ninja -C out/Default”

  3. Goto Behaviour tab, change clean command to “-t clean”
