I have double checked that the package mimick_vendor has been installed, I have tried
ahmadnav commentedon Nov 15, 2021
This error can be resolved by setting the following in cmake, after making mimick_vendor from source
set(mimick_vendor_DIR /home/ros2_android_dep/install/mimick_vendor/share/mimick_vendor/cmake)
set(mimick_DIR /home/ros2_android_dep/install/mimick_vendor/lib/cmake/mimick/)

I presume you are following the build instructions for Android, is this correct?
We worked around the issue with mimick in our CI by not building tests for some packages. This is done by creating a colcon.meta file in the workspace with the following contents:
ros2_java/.github/workflows/build_and_test.yml
Lines 37 to 61 in 5134c54
I think we should update the README to reflect the changes in the CI script.
ahmadnav commentedon Nov 15, 2021
That's true. Thanks Jacob I would also like to add the you have to add -DBOOST_ROOT=/opt/boost/boost_1_77_0/boost
-DBOOST_INCLUDEDIR=/opt/boost/boost_1_77_0/boost
as a Cmake arg other wise asio.hpp is not detected. You have to use ndk 21+ as the <18 cause a compile error, failing basic test.

I have gotten the same issue with spdlog_vendor, will update when I find the solution. After setting -Dspdlog_vendor_DIR=/opt/ros/galactic/share/spdlog_vendor/cmake the error than changes to
CMake Error at CMakeLists.txt:19 (find_package):

I have no solution for this at the moment as there is no such files as spdlogConfig.cmake or spdlog-config.cmake
jacobperron commentedon Nov 16, 2021
We shouldn't need spdlog as I'm pretty sure we're not relying on
rcl_logging.I'll try going through the Android setup myself and see if I can update the instructions for a smoother experience.
ahmadnav commentedon Nov 17, 2021
Thanks Jacob, Now I get the following error;
eProsima/Fast-DDS/src/cpp/rtps/transport/UDPChannelResource.h:18:10: fatal error: 'asio.hpp' file not found
I definitely have boost and libiso installed, and can see asio.hpp in /usr/include.

As for the asio.hpp issue you need to git submodule update --init --recursive within the Fast-DDS directory, to get the asio libraries under thirdparty (which are currently link folders so aren't cloned) than add
within target_include_directories(${PROJECT_NAME} PUBLIC ) in eProsima/Fast-DDS/src/cpp/CMakeLists.txt

@jacobperron I can't seem to find a solution to the spd log issue. Not sure why spdlog_vendor requires spdlog as well
EDIT
set(RCL_LOGGING_IMPLEMENTATION rcl_logging_noop) in rcl CMAKE removes this dependency otherwise the get_default_rcl_logging_implementation() call brings it in. This allows for ignoring spdlog. Its finally compiled now.
