A2DP: Clear the collision mask while disconnecting While remote is opening AVDTP channel, the stack setup a coll_mask flags with a signalling timer, and takes over the control after timer expired. This prevents the connection collision. However, if there were two incoming connections at the same time, the timer was overridden by the second connection, and this flags of the first connection kept activated, but the following outgoing connection was blocked. In order to prevent the worng flags, this change reset flags while disconnecting. Bug: 146849922 Test: Connect with multiple A2DP sinks Change-Id: I4baff647d22f1148bf6fa2b61e778652c9c90091
Just build AOSP - Fluoride is there by default.
Instructions for Ubuntu, tested on 14.04 with Clang 3.5.0 and 16.10 with Clang 3.8.0
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/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 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/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
cd ~/fluoride/bt gn gen out/Default
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.
cd ~/fluoride/bt/out/Default LD_LIBRARY_PATH=./ ./bluetoothtbd -create-ipc-socket=fluoride
Follows the Chromium project Eclipse Setup Instructions until "Optional: Building inside Eclipse" section (don't do that section, we will set it up differently)
Generate Eclipse settings:
cd packages/modules/Bluetooth/system gn gen --ide=eclipse out/Default
In Eclipse, do File->Import->C/C++->C/C++ Project Settings, choose the XML location under packages/modules/Bluetooth/system/out/Default
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"
Goto Behaviour tab, change clean command to "-t clean"
