A2DP: Don't wait for role switch on a blacklisted device

When there are 2 or more ACL links, we will try to be the master for
better link quality, and setup flags to wait for the following role
switch results. Because this is an asynchronous task, we would check
flags for any further actions. However, there would not be other results
for role switch IOP, and could be just ignored.

Bug: 141177108
Test: Add headset to IOP and do A2DP playback manually

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/system/bt

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/aac
git clone https://android.googlesource.com/platform/external/libchrome
git clone https://android.googlesource.com/platform/external/libldac
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

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

cd system/bt
mkdir third_party
cd third_party
ln -s ../../../external/aac aac
ln -s ../../../external/libchrome libchrome
ln -s ../../../external/libldac libldac
ln -s ../../../external/modp_b64 modp_b64
ln -s ../../../external/tinyxml2 tinyxml2
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 system/bt
gn gen --ide=eclipse out/Default

  1. In Eclipse, do File->Import->C/C++->C/C++ Project Settings, choose the XML location under system/bt/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”
