It seems I shall change libc++ to gnustl_static
Try to figure out how to change this

Gosh this has been on the list for quite a while, really should find some time to get android working. From a glance, the .a libs appear correct, might need to test compilation on my end with the https://github.com/raksa/SocketIO-cpp-lib prebuilds and let you know if I can debug the errors.

@HeadClot There was some investigation a few weeks ago, added possible boost libs for android here: 638dd92, but the compatible clang compilation of the sioclient is still outstanding. Unfortunately other priorities has left that work unfinished at this time. Don't have a solid eta right now, but will likely revisit this in a month or so.

Contributions are always welcome :)

getnamo commented on May 20, 2024

The plugin doesn't currently have a static library for android. This is required before the plugin can be used on the android platform.

The steps to do this is to take socket.io c++ and build it for the android platform as a static lib and merge it into the plugin + some Android Packackaging Language script (APL) xml to copy the static libs to your android package (e.g. see GoogleVR APL).

Pull requests welcome!

See: #19 for more guidance, another dev is trying to set everything up for IOS.

tlightsky commented on May 20, 2024

trying to do this,
so I shall compile the source to a static lib by ndk first?

from socketioclient-unreal.

getnamo commented on May 20, 2024

I believe that's right. You need to compile 2 libraries: Socket.io and boost (only 3 submodules needed), the specific sources used in this plugin are found here: https://github.com/getnamo/socketio-client-prebuild/tree/master/src

at the end you should get 4 .a static libs for each platform, something like this (names taken from linux build):

Boost

libboost_date_time-mt-1_60.a
libboost_random-mt-1_60.a
libboost_system-mt-1_60.a

Socketio

libsioclient.a

Once you do this use the changes in in this branch: https://github.com/getnamo/socketio-client-ue4/tree/platforms to try and compile/link everything for Android. I've added what I think should be the correct APL file, whitelist, and build.cs changes. rename your static libs to fit and it should all link in theory :)

Edit: changed .so to .a, here it looks like we link statically vs an example I was referring to. I wonder if the APL is still needed if we link statically?

from socketioclient-unreal.

tlightsky commented on May 20, 2024

I have the same question,
not quite sure what role the APL file played in all the plugin system.
Still working on compiling boost and sioclient.

from socketioclient-unreal.

tlightsky commented on May 20, 2024

find some prebuild boost (https://github.com/emileb/Boost-for-Android-Prebuilt/tree/master/boost_1_53_0)
can I just use there prebuild .a for a test?

from socketioclient-unreal.

getnamo commented on May 20, 2024

We use boost 1.6, if you find a prebuild for that version, it should be compatible. Note that the full boost static lib can be quite large, which is why we only need the three modules.

from socketioclient-unreal.

tlightsky commented on May 20, 2024

I compile boost by this answer:http://stackoverflow.com/a/40022669/707606
get these files:

libboost_date_time-clang-darwin-mt-1_62.a
libboost_random-clang-darwin-mt-1_62.a
libboost_system-clang-darwin-mt-d-1_62.a

how do I know is it right or not

from socketioclient-unreal.

getnamo commented on May 20, 2024

Those may work, but they're a bit newer than what is used here. You can try them, and if they don't work just swap the source for boost 1.6 (linked here: https://github.com/getnamo/socketio-client-prebuild/tree/master/src).

With that step done, follow the same format to compile socket.io again from the source linked above and it should be the correct ones.

Also note the platform built using the above method (looks like that compiled for arm-linux-androideabi) and compare it to your android hardware (http://android.wonderhowto.com/how-to/android-basics-see-what-kind-processor-you-have-arm-arm64-x86-0168051/) so that those match as well. For example my phone is an S6 so I would need arm64-v8a library version.

from socketioclient-unreal.

tlightsky commented on May 20, 2024

I see,mine is ARMv7.
I'll use 1.6.0
trying to get it run on armv7.
the name clang-darwin really confused me, should it be something like arm-linux-androideabi

from socketioclient-unreal.

tlightsky commented on May 20, 2024

I compile boost successfully by these config:

using gcc
: arm_linux_android_4.8
: ${ANDROID_NDK_STANDALONE}/bin/arm-linux-androideabi-g++
;

./b2 \
   -d+2 \
   -j 4 \
   --reconfigure \
   target-os=linux \
   toolset=gcc-arm_linux_android_4.8 \

   link=static \
   variant=release \
   threading=multi \
   --layout=versioned \
   --prefix=~/app/boost \
   install

now trying to compile socketio,
trying to change CMakeLists.txt:

set(CMAKE_CXX_COMPILER ${NDK_STANDALONE_TOOLCHAIN}/arm-linux-androideabi/bin/g++)

no luck

from socketioclient-unreal.

tlightsky commented on May 20, 2024

keep get this:

Could not find the following static Boost libraries:

          boost_system
          boost_date_time

Edit:

change b2 to bjam solved problem before,
now it's

getnamo commented on May 20, 2024

Clang is the compiler (like gcc) I believe ue4 uses clang to compile android and NDK is moving to clang completely. It's a good idea to match the compilers. So clang seems correct, darwin I don't think is correct.

Looking through the web I found: http://comments.gmane.org/gmane.comp.lib.boost.devel/264764 which is a script to build boost through ndk using clang, in the mailing list they also give the command to use the script to build boost

Here is example how we build it with clang-3.7:

$ ./build/tools/build-boost.sh --abis=armeabi-v7a,x86 --version=1.60.0
--stdlibs=llvm-3.7 $BOOST_DIR

Here BOOST_DIR is directory containing folders named '1.59.0', '1.60.0',
etc.

You also need to match the headers with the same libraries (1.6 with 1.6, not 1.62), unless there has been no api change. These should be available for socket.io static lib to build but otherwise not needed in this plugin.

To build the socket.io static lib it will be a mix of these instructions:
https://github.com/socketio/socket.io-client-cpp/blob/master/INSTALL.md

but translated to use ndk clang to build a static lib:
http://web.guohuiwang.com/technical-notes/androidndk1

tlightsky commented on May 20, 2024

I compile it all through with ${NDK_STANDALONE_TOOLCHAIN}/arm-linux-androideabi/bin/g++ and get all the 4 .a files.
I'll give it a shot tomorrow, and see clang later.

It's stange that afte Plugins compiled on Mac, I still can't add Socket.io component.

tlightsky commented on May 20, 2024

I notice that:
in SocketIOClient.Build.cs

                PublicAdditionalLibraries.Add(Path.Combine(BoostLibPath, PlatformString, "libboost_date_time.a"));
                PublicAdditionalLibraries.Add(Path.Combine(BoostLibPath, PlatformString, "libboost_random.a"));
                PublicAdditionalLibraries.Add(Path.Combine(BoostLibPath, PlatformString, "libboost_system.a"));

in SocketIOClient_APL.xml

		<copyFile 	src="$S(PluginDir)/../../ThirdParty/Boost/Lib/Android/armeabi-v7a/libboost_date_time-mt-1_60.a"
			    	dst="$S(BuildDir)/libs/armeabi-v7a/libboost_date_time-mt-1_60.a" />

It seems didn't use the .a file when compiling,
I think I should find out the compile command it use to check if it use the .a or not.

I'm sadly not familiar with the android build system to that extent. I will need to find some time to give it a good look which may be a week or more. The general setup is you need the 4 static libs compiled using clang, for your android platform. I don't think we should need APL because we're using static libs (.a) instead of shared objects (.so akin to dynamic libraries), but that may be wrong.

Beyond that, reach out on the unreal answerhub/forums, there are other people compiling for android and may have a better guide on how to compile the libs properly for UE4.

Any updates on this? I'm also interested in using this plugin on mobile (android). I might have some bandwidth to start messing with the compiling soon, but I don't have any low-level android dev experience so results may vary.

@Dr-Jerm If you can get boost and https://github.com/socketio/socket.io-client-cpp to compile for armv7/armv8 using clang, then the rest should work as is. See this thread for more details of the things that have been tried.

Any news about this?

I'm trying to compile socket.io for android, but..

Can someone helps?
My steps is:

~~get socket.io prebuild source https://github.com/getnamo/socketio-client-prebuild~~
~~install Boost http://www.boost.org/users/history/version_1_65_1.html~~
~~install CMake https://cmake.org/download/~~
~~compile prebuild on windows and get sioclient.lib file~~
get libsioclient.a from https://github.com/raksa/SocketIO-cpp-lib/tree/master/sio-client/android/arm
copy libsioclient.a file to {my_ue4_project}\Plugins\socketio-client-ue4\ThirdParty\SocketIO\Lib\Adnroid
get libboost_date_time.a, libboost_random.a, libboost_system.a from https://github.com/raksa/SocketIO-cpp-lib/tree/master/boost/android/lib
copy .a files to {my_ue4_project}\Plugins\socketio-client-ue4\ThirdParty\Boost\Lib\Adnroid
compile with errors, but i can't see it (maybe wrong version of libs)

also..
I have only UE4-SIOJson-armv7-es2.a in {my_ue4_project}\Plugins\socketio-client-ue4\Binaries\Android
Do I need something like a UE4Editor-SocketIOClient.dll in this folder?

@getnamo - Any news on android support for this plugin?

from socketioclient-unreal.

@getnamo Hi :D first of all let me say. Awesome work you did there with this plugin! Android and Linux support would be extremly usefull though. anything new on that?

from socketioclient-unreal.

getnamo commented on May 20, 2024

Note to self: Android does compile in https://github.com/getnamo/socketio-client-ue4/tree/android-work, but crashes on connect. Will need different and matching libs.

Not a permissions issue since udp works as expected on device.

Hi @getnamo , thanks for this excellent plugin. Works perfectly on Windows, when trying to build for Android or Launch to Android device (Oculus Go in this case) using the android-work branch you mentioned above, we encounter different issues. Ie. it does not compile but the build fails on

'pthread_condattr_setclock':
[...]/Plugins/SocketIOClient/Source/ThirdParty/asio\asio/detail/impl/posix_event.ipp(39,17) : error: no member named 'pthread_condattr_setclock' in the global namespace; did you mean 'pthread_condattr_setpshared'?

and later:

Plugins\SocketIOClient\Source\SocketIOClient\Private\SocketIOClient.cpp(132,5) : error: unknown type name 'FScopeLock'
PackagingResults: Error: unknown type name 'FScopeLock'

I am not familiar with Android development so I'm also stuck here but thought this info could be useful for you?
Please let me know whether/how I can support in resolving this issue and expanding the horizon for the plugin.

getnamo commented on May 20, 2024

android-work has been merged into master with additional fixes added there, re-pull latest master branch and try again.

Looking at ~ 4.22 for a new binary release.

RogueSheep-nl commented on May 20, 2024

Wow great work!
The app builds and the SocketIO seems to work according to my first tests.
Don't have access to our dev server for proper testing, will properly test next week when I have access again.
Thanks!

RogueSheep-nl commented on May 20, 2024

Sorry for the silence, had to switch to a different project for a moment.
With the latest master I was able to build and run out application on the Go (Android) and have it communicatie with/through the server. Did not get around to do extensive testing but that will come as the project progresses.
Thanks again for this quick update.

getnamo commented on May 20, 2024

new binary release: https://github.com/getnamo/socketio-client-ue4/releases/tag/1.0.0 now includes android support.

Working, closing issue. Open new issue if you find problems with android build.
