Building WebRTC for Android

[Manjesh (GoCast)]

Hi everyone,

I am working on a project that involves building WebRTC for Android. While going through the posts on this group, I've come across some members who have been able to build WebRTC for Android successfully. Since I didn't find any descriptive post as to how to build for Android, I have started this thread in the hopes of making it a one stop information shop for people interested in building WebRTC for Android. Let me start of the discussion by putting up the following questions to members who have successfully built WebRTC for Android:

1. What revision of the WebRTC source did you use?

2. What version of Android source/ndk did you use?

3. Is the ndk alone sufficient to build WebRTC or do you need the complete Android source code?

It would also be of great help if you could describe the steps you took to get WebRTC to build on Android.

Thanks,

Manjesh

The port has been started with the version of the 18th of November. Then
evolution of the source code has been tracked.

Android ndk r7 on an Ubuntu machine.

Android ndk is sufficient.

Nearly all the work has been done by the Google team, Android.mk are
present in the src tree, only few are missing in the third_party three
but they are easy to add, adaptation to Android is present when needed.

It has only been necessary to develop a minimal Java/C++ application
based on the peerconnection sample and to fix minor compilation issues.

Still in debug phase... with a Nexus One and a Linux box.
The Nexus One - even with Neon support - does not seem to have enough
horse power to decode VP8 frames. VP8 encoding is better.
Debug is going to be continued with a tablet based on Tegra 2.

Best regards,

Hello Manjesh , 

To help, you should consider using the Linphone open source SIP software , which runs on different platforms :

• Linux/x86 and Linux/x86-64
• Windows XP and Vista
• Linux/ARM: without graphical interface. Linphonec or liblinphone are good candidates to provide the software stack of an hardware phone or hardware communication system.
• Linux/Blackfin: The uclinux.org project maintains a port of linphone for blackfin processors, without gui. Performance are impressive. See here for details.
• MacOS X x86 : audio and video. You can download a standalone bundle from this website or, use macports.
• Google Android: audio and video, download with the Android Market from your phone.
• Iphone OS: audio and video, download from the AppStore on your iphone/ipad or ipod touch.
• Blackberry OS: Audio only, pure j2me version of Linphone. 
• WebOS : unofficial port, see information here: http://www.webos-internals.org/wiki/Application:Linphone

and last , but not least , Ipad 2 .  

Look at http://www.linphone.org/ and  http://www.belledonne-communications.com/ 

Linphone uses open source and royalty free codecs such as VP8 and iLBC , speex-HD.

Hey Christian,

As you had specified, I downloaded Android NDK r7 on Ubuntu 11.04, and checked out WebRTC r1095. Then I tried to build 'trunk/src/voice_engine/main/test/android/android_test' voice engine test app by executing:

ndk-build -e

Everything is going along fine, but then I receive this error:
                      -----------------------------
SharedLibrary  : libwebrtc_audio_preprocessing.so
./obj/local/armeabi/libwebrtc_apm.a(audio_buffer.o):(.data.rel.ro+0x10): undefined reference to `vtable for __cxxabiv1::__class_type_info'
                      -----------------------------

Did you ever come across this error? Please let me know?

[Paul D.]

After trudging my way through a few errors, I have also run into this
one.
Please advise.

[Manjesh (GoCast)]

Hi Paul,

I think that error occurs when you try to run the test app on the simulator. I ran the app on my nexus and it worked.

So try running the app on the device.

Hi Manjesh,
Wondering how you was able to build it...

Could any someone please help me to build it for Android?

I have Ubuntu 11.10 32bit. Downloaded latest version of WebRTC (r1525), installed latest ndk (r7) but was not able to compile it for Android.
I successfully did it for ubuntu, but not for Android.

The first problem that I faced with was this:
include $(LOCAL_PATH)/../../external/webrtc/android-webrtc.mk

First of all for some reason LOCAL_PATH points to NDK folder, not to project one (jni/Android.mk:57: /home/artem/Development/android-sdks/android-ndk-r7/build/core/../../external/webrtc/android-webrtc.mk: No such file or directory)

The second problem is that there is no "external" folder in NDK and I replaced it with path to my project's folder

And after that I got a lot of compilation errors:
artem@artem-nb:~/Development/eclipse_workspaces/webrtc/webrtctest$ ndk-build
Compile++ thumb  : webrtc_apm_process_test <= process_test.cc
jni/src/modules/audio_processing/test/process_test.cc:17:25: error: gtest/gtest.h: No such file or directory
jni/src/modules/audio_processing/test/process_test.cc:25:67: error: external/webrtc/src/modules/audio_processing/debug.pb.h: No such file or directory
jni/src/modules/audio_processing/test/process_test.cc:39: error: 'webrtc::audioproc' has not been declared
jni/src/modules/audio_processing/test/process_test.cc:40: error: 'webrtc::audioproc' has not been declared

.......





Also I tried to build "trunk/src/voice_engine/main/test/android/android_test" but without success either - NDK was not able to include other Android.mk files because LOCAL_PATH was initialized as "jni".

Could someone please help me to sort out these issues

Thanks
Artem

[Gustavo]

I've also built it recently, I'll try to post all the details latter,
but asking to your concrete questions:

Regarding the first problem, change it to:
"include $(MY_WEBRTC_ROOT_PATH)/android-webrtc.mk"

Regarding the second problem:
Simplest solution is to avoid compiling webrtc_apm_process_test.
Modify /src/modules/audio_processing/Android.mk to comment the lines
related to that component.

[Artem]

Thanks Gustavo,
Will be wait your post. Meanwhile I've tried to modify /src/modules/audio_processing/

Android.mk and build process has been started, but then new errors occurred:

Seems to me now I have problems with stl library - maybe I should set some variable to compile without stl? Because in system_wrappers I see some files like these: list_stl and list_no_stl

[Artem]

Faced with the same issue as described above:

and so on ...

[Gustavo]

You have to disable rtti to get rid of that error.

I've built webrtc for android recently (although I'm just interested
in the voice part and disabled most of the video components). Find
below the most important files I added or modified:

Android.mk https://gist.github.com/1672311
Application.mk https://gist.github.com/1672321

I'm using ndk-r7 and launching the build with this command:
ndk-build NDK_PROJECT_PATH=. NDK_APPLICATION_MK=Application.mk

In addition I had to:
- Disable some tests projects.
- Add missing files in src/modules/rtp_rtcp/source/Android.mk
- Remove -DWEBRTC_MODULE_UTILITY_VIDEO in src/modules/utility/source/
Android.mk
- Remove calls to missing function "copy" in src/modules/rtp_rtcp/
source/rtp_packet_history.cc (Don't know if it has any impact)
- Remove ThreadPosix::SetAffinity in src/system_wrappers/source/
thread_posix.cc

Probably I'm forgetting something. Don't hesitate to ask for more
details or anything else.

[Manjesh (GoCast)]

Hi Artem,

Regarding the "debug.pb.h" not being available, you have to run the executable 'protoc' to generate the file along with its .cpp counterpart, which is part of the protobuf-lite source.

I am actually using webrtc r1095, with Ubuntu 11.04 32 bit. I have managed to get the voice engine test to run on my nexus. I am still in the process of getting the entire

webrtc source to build. Please let me know if you have any specific questions.

Thanks, Gustavo and Manjesh.
I applied almost all of your changes and got the following error:

Thanks Manjesh,
Could you please give me some kind of example how to run 'protoc' - I can't find it in my project and don't even know who 'protoc' is and how to deal with it. And I guess I should specify desired target (PC or Android) somewhere.

I stuck currently with the following and on other forum people say that 'protoc' helped.

Just found the issue: I needed to add LOCAL_LDLIBS +=-lOpenSLES

Has anyone compiled the Video modules already?

[Manjesh (GoCast)]

Hi Everyone,

I have successfully built and audio-only version of PeerConnectionClient example fo Android. When I start a call, libjingle goes through its usual routine of creating stun ports and finding out the best path. Since both my devices are on the same LAN, it chooses the LAN path, and the peers send STUN pings to one another. Ideally at least one of them should receive an ACK packet back. But it looks like that's not happening. As a result, the connection is deleted after a timeout.

Has anybody else grappled with this issue while building for Android? Any insight in this regard is tremendously helpful.

- Manjesh

[Zhihong GUO]

Hi Manjesh,

Could you please tell how to get the PeerConnectClient source code for
Android? I download webrtc source code but no source codes in
peerconnection folder.

I build webrtc for Android by ndk and its Android.mk files. Now I can
run the apk built from src/voice_engine/main/test/android_test/, but
the apk seems not rely on peerconnection, so that I what to build a
new webrtc package support peerconnection.

You can get example client and server code from

http://code.google.com/p/libjingle/source/browse/trunk/talk/examples/peerconnection

but it is oriented towards Windows or Linux, no Android AFAIK. You could still see the difference between those two implementations and guess what you need to implement in order to have an Android client.

Hi Gustavo,

How to disable rtti. I am facing the same issue.

[Luke Weber]

Hey, 

I posted a message with my diff and the libs, but it got deleted immediately, would be nice if they just stripped attachments or didn't allow it to begin with as I had a bit of instruction in it, which is now lost. Moderator?

Anyhow, the diff from what I did, as well as compiled libs that could be used directly, are located here:

https://github.com/lukeweber/webrtc-demo-files

I finally got around using static for libstlport, but I think it might have been related to actually using libstlport_shared explicitly in my android.mk, as it was previously just libstlport.

Best of luck,

Luke

[Brijesh Thakur]

Thansk a ton Manjesh , Artem , Gustavo , Luke.

I have successfully compiled and tested on Android Device. I am able to run Android Test as well to Communicate between two devices over Wifi.

[Luke Weber]

As a semi-natural extension for me, that maybe not everyone has figured out yet.

This is an audio test, meaning the two clients don't support any fancy peer to peer stuff, just opening up RTP streams between each other on the same network.

So where to from here, two options for me:

1) Change the peerconnection client examples to compile some functionality into this test and try that out. The downside here is that webrtc uses roap and jsep, and hasn't fully implemented ICE, ie it's missing TURN(relay server) support(http://code.google.com/p/webrtc/issues/detail?id=278), which is 8% of your clients if you believe libjingle's stats.

2) Try to figure out how to use the libjingle client for signalling and ICE, and webrtc's voice engine. The obvious first problem here, is that webrtc is into managing it's RTP streams inside the voice engine, and libjingle also seems to have it's RTP streams as part of it's ICE client/session logic. In this sense, I'm not yet really sure where to start.

Anyone have any thoughts on point 2, specifically the best way to merge these two projects to use libjingle as a client and webrtc as the audio engine. 

Luke

[Mamadou]

For the signaling protocol: http://tools.ietf.org/html/draft-uberti-rtcweb-jsep-02
No you cannot call SIP clients
For info, the Android chrome version don't support webrtc yet (at
least the part you're insterested in: Peerconnection).
If you want to know what it's possible to do with WebRTC/SIP combo:

gyp doesn't do the cross compile for mac correctly without a bit of patching, and Android.mk files seem to never fully be up to date. 

You can check out my project to see one option where you could build it by maintaining Android.mk files for example. I also did have the gyp system working, but haven't tested it in a while, and gave up on it as a primary option because it was too much hassle to maintain two.

Hi All,

anyone please give help.

I have tried to build on Mac.

tried ndk-build inside android_test directory but it shows Error:

make: *** No rule to make target `jni/../../../../../../../src/modules/rtp_rtcp/source/bandwidth_management.cc', needed by `obj/local/armeabi/objs-debug/webrtc_rtp_rtcp/bandwidth_management.o'.  Stop.

tried to build video_engine as well but shows more errors..

Please help

Thanks

Hi,

Thanks for your reply. It helped me.

Now I am getting this Error

Using SDK build

readlink: illegal option -- f

usage: readlink [-n] [file ...]

Warning: Current directory is out of CHROME_SRC, it may not be the one you want.

-bash: /build/android/adb_device_functions.sh: No such file or directory

Does it need chrome source while building for android. is there anything else that I am missing out.

Please help.

Thanks

Check out build/andoid/envsetup.sh in my project.

Hi,

In github looks like your build directory is empty. Please check.

Thanks

Hi,

Looks like my SDK and NDK are in path but I get this when I tried to give $ ./build/android/envsetup.sh

ANDROID_NDK_ROOT must be set to the path of Android NDK, Revision 6b.

which could be installed by

<chromium_tree>/src/build/install-build-deps-android-sdk.sh

./build/android/envsetup.sh: line 23: return: can only `return' from a function or sourced script

ANDROID_SDK_ROOT must be set to the path of Android SDK, Android 3.2.

which could be installed by

<chromium_tree>/src/build/install-build-deps-android-sdk.sh

./build/android/envsetup.sh: line 31: return: can only `return' from a function or sourced script

TARGET_PRODUCT: trygon is not supported.

./build/android/envsetup.sh: line 64: return: can only `return' from a function or sourced script

Can not find Android toolchain in /third_party/android_tools/ndk//toolchains//prebuilt//darwin-x86/bin/.

The NDK version might be wrong.

./build/android/envsetup.sh: line 81: return: can only `return' from a function or sourced script

Thanks

Probably the environment setup is partially applicable from the readme on my project. Beyond that, it's always a bit of a hack.

Hi,

Thank you for your help, but still no luck.

I have checked all sdk and ndk tools work from terminal, so environment is set.

No I cant understand what else hack that I have to do to get this stuff to work.

I am using a mac machine with Mountain Lion

Thanks

[Leo Wang]

We only support LINUX as the host right now. I don't recommend that
you spend too much time on hacking Mac.

Also, please let me make clear, if you want to build full webrtc
stack, please follow the instructions at www.webrtc.org, check android
section.

https://sites.google.com/site/webrtc/reference/getting-started

You should use gyp which is also used by chromium. Please post
question if it doesn't work. We don't support anything other than it
right now.

Thanks

Would be cool if there was some mac support. Some stuff is just broken in chromium, where it's obviously trying to support mac, but the case just doesn't work. 

I've attached a patch. I've removed video haphazardly. I assume video code isn't compiling because the gas*.pl scripts aren't working on mac for libvpx, but didn't have time to look further, but you can reenable video, compiling vpx etc if you want to give it a shot.

As far as the audio demo, I made some changes, but realized it's just bogus.

Basically, adapt webrtc/voice_engine/test/android/android_test/jni/Android.mk to the format of video engine if you want webrtc/video_engine/test/android/android_test/jni/Android.mk, which just pulls the statics our of the out/build directory from gyp.

Other option is figure out where the build breaks, build the whole thing, then use the video demo, which seems to be maintained.

same problem 

[Maulik Prabhudesai]

1. The one mentioned on WebRTC-getting started web page

2. the latest ndk

3. what do you mean by Android source code ? if you mean SDK also the latest.

Whilst there are instructions for building WebRTC on Android, and they do work, it is a non-trivial job getting the build environment up and running in the first place if you aren't already an Android developer.

If all you need is a working WebRTC testbed on Android, the current Chrome Beta includes WebRTC behind a flag. If that is a recent enough implementation for your purposes then it will save you a *lot* of work.
