A2DP related API update and cleanup

* Added new A2DP API and use it as appropriate
  - A2D_GetTrackFrequency()
  - A2D_GetTrackChannelCount()
  - A2D_GetNumberOfSubbands()
  - A2D_GetNumberOfBlocks()
  - A2D_GetAllocationMethodCode()
  - A2D_GetChannelModeCode()
  - A2D_GetSamplingFrequencyCode()
  - A2D_GetSinkTrackChannelType()
  - A2D_GetSinkFramesCountToProcess()

* Added corresponding unit tests for the new API

Also, A2DP related cleanup:
 - Renamed A2D_sbc_dump_codec_info to A2D_DumpCodecInfoSbc()
 - Changed the order of tA2D_SBC_CIE.min_bitpool and
   tA2D_SBC_CIE.max_bitpool to reflect the order of the corresponding
   fields in the Bluetooth spec (A2DP spec v1.3, page 21).
 - Added new API A2D_GetMediaType() and the corresponding unit test
 - Renamed AVDT_MEDIA_AUDIO to AVDT_MEDIA_TYPE_AUDIO
 - Renamed tA2D_SBC_CIE.alloc_mthd to alloc_method
 - Renamed A2D_BAD_ALLOC_MTHD to A2D_BAD_ALLOC_METHOD
 - Renamed A2D_NS_ALLOC_MTHD to A2D_NS_ALLOC_METHOD
 - Eliminated usage of A2D_MEDIA_TYPE_AUDIO and replace it with
   AVDT_MEDIA_TYPE_AUDIO.
    Now the media_type value everywhere is the AVDT_MEDIA_TYPE_* value
    without the reserved 4 bits (LSBs).
 - Fixed macro defines in file "stack/avdt/avdt_defs.h"

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 15.10 with GCC 5.2.1.

Install required libraries

sudo apt-get install libevent-dev

Install build tools

  • Install ninja build system
sudo apt-get install ninja-build

or download binary from https://github.com/ninja-build/ninja/releases

  • Install gn - meta-build system that generates NinjaBuild files.

Get sha1 of current version from here and then download corresponding executable:

wget -O gn http://storage.googleapis.com/chromium-gn/<gn.sha1>

i.e. if sha1 is "3491f6687bd9f19946035700eb84ce3eed18c5fa" (value from 24 Feb 2016) do

wget -O gn http://storage.googleapis.com/chromium-gn/3491f6687bd9f19946035700eb84ce3eed18c5fa

Then make binary executable and put it on your PATH, i.e.:

chmod a+x ./gn
sudo mv ./gn /usr/bin

Download source

mkdir ~/fluoride
cd ~/fluoride
git clone https://android.googlesource.com/platform/system/bt

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

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

Fluoride currently has dependency on some internal Android projects, which also need to be downloaded. This will be removed in future:

cd ~/fluoride
git clone https://android.googlesource.com/platform/system/core
git clone https://android.googlesource.com/platform/hardware/libhardware
git clone https://android.googlesource.com/platform/system/media

Configure your build

We need to configure some paths to make the build successful. Run:

cd ~/fluoride/bt
gn args out/Default

This will prompt you to fill the contents of your "out/Default/args.gn" file. Make it look like below. Replace "/home/job" with path to your home directory, and don't use "~" in build arguments:

# Build arguments go here. Examples:
#   is_component_build = true
#   is_debug = false
# See "gn args <out_dir> --list" for available build arguments.

libhw_include_path = "/home/job/fluoride/libhardware/include"
core_include_path = "/home/job/fluoride/core/include"
audio_include_path = "/home/job/fluoride/media/audio/include"

Then generate your build files by calling

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
