v1.2 build errors with Android NDK #305
Comments

Hi @INRIX-joel-winarske, Thanks for the feedback, we will investigate this issue! |
|
what is the cmake command that you are using? |
|
[ 19%] Building CXX object CapabilityAgents/AudioPlayer/src/CMakeFiles/AudioPlayer.dir/AudioPlayer.cpp.o The entire Alexa device stack (sqlite3, gtest, nghttp2, zlib, mbedtls or openssl, curl, portaudio, gstreamer, avs-device-sdk) builds fine and generates SampleApp if I apply the cast workarounds for the two files I mention. |
|
We have tried cross compiling successfully with NDK 14b. The environment variables are: export ANDROID_HOME=~/Library/Android/sdk And the cmake command is: You might have to add gstreamer and portaudio dependencies as well to this. |
|
That's building with the Android Studio bundled NDK. What's the verbose build output? Perhaps it's as simple as a compiler flag. |
|
yes with Android Studio bundled NDK. We do not have the build output currently as it was compiled few months back. Can you cross check your cmake options with the ones that I have listed? |
|
It's a newer version of NDK than what I'm using. I generally only use the Studio NDK for simple libraries. I'll take a closer look at what you provided and get back to you. Thanks. |
|
there were some problems on other versions of NDK, so if can you try with NDK 14b |
|
For now I'm sticking with 15b and patching the cast in my build script. This makes lots of things easier for me, and I can still single step the C/C++ libraries via Studio. I have portaudio working on target via OpenSLES, I just need to sort out the gstreamer issues I'm seeing. Were the >14b issues related to build or runtime? |
|
issues were build time |
|
Cool thanks |
|
Hi @jwinarske , can you share the cmake command or CMakefile that you used for cross compiling? It will help us improve our build for android. |
|
Hi Mradula you can have your PM contact me. |
|
Hello INRIX-joel-winarske, Did our PM get in contact with you? If not, and you still want to get in touch, please fill out this Contact Form and we will get in touch with you. If this is no longer an issue, please feel free to close this issue. Thank you, |

Hi INRIX-joel-winarske, We have problems when using NDKr14b build AVS SDK 1.4 for Android 6.0 Jack |
|
Hello INRIX-joel-winarske, |
|
Hi,
I am able to build AVS SDK with the current Android NDK on Linux Ubuntu 16.x LTS. I build the same stack from source that I use for Linux, which is:
sqlite3
portaudio GLES
gtest
nghttp2
mbedtls
zlib
curl (http only)
gstreamer
avs-device-sdk
I have a series of patches for gstreamer. I get's complicated, although I can run the AVS Device Sample app in an Android Emulator using a USB Microphone. It's responsive, and works well.
Joel

Hello INRIX-joel-winarske,
Are successfully able to build the AVS SDK with Android NDK ? I am new Android NDK build process, how to build the AVS sdk with Android NDK. can you please provide the instructions how to do it?

Hi Joel, What type of c++ library you use, gnustl or llvm-libc++? Jack |
|
Hi Jack,
...
-DANDROID_STL=c++_shared \
-DAMAZON_KEY_WORD_DETECTOR=OFF \
-DKITTAI_KEY_WORD_DETECTOR=OFF \
-DSENSORY_KEY_WORD_DETECTOR=OFF \
...
c++_shared is stable only >= NDK r16.
I haven't had a need for wake word, as my current market sector is Automotive.

Hi Joel,
What type of c++ library you use, gnustl or llvm-libc++?
Do you build sdk also include WakeWordEngine(Kitt.ai or Sensory)?

Hi Joel, I changed ndk to r16 with libc++_shared library, I also build without WakeWordEngine, WARNING: linker: SampleApp: unused DT entry: type 0x1d arg 0x2707e I use tombstone to check log as below: It seems the problem happened in AVSCommon/Utils/src/Logger/ConsoleLogger.cpp:59 Thanks. |

Hi Jack,
I haven't seen that. Don't forget you need to copy libc++_shared lib to the target, it's not part of the Android image.
For testing I do the following on a test device:
Push all libs to target "lib" folder: /data/data/my.app.location/files/lib
Exes to target: /data/data/my.app.location/files
Copy cert file to target: /data/data/my.app.location/certs
Then do something like this from "adb shell":
export LD_LIBRARY_PATH=/data/data/my.package.name/files/lib
export CA_CERTIFICATES=/data/data/my.package.name/certs/ca-certificates.crt
export TZ=UTC
./SampleApp /data/data/my.package.name/files/AlexaClientSDKConfig.json DEBUG9

Do you have the same problem before?

Hi Joel, Do you build avs sdk also use NDK generate standalone toolchain? Several Steps want confirm with you. We use NDK16 generate standalone toolchain by below command: And below is our build script: CROSS_COMPILE=/home/jackho/arm_ndk_r16_libc/bin/arm-linux-androideabi- #And the cmake command is: Is there anything we miss to do? Thank you. Jack |

Hi Jack,
For Clang with arm I use:
export CC=
export CXX=
export LINK=
export LD=
export AR=
export RANLIB=
export STRIP=
export ARCH_FLAGS=" -march=armv7-a -mfloat-abi=softfp -mfpu=vfpv3-d16 "
export ARCH_LINK=" -Wl,--fix-cortex-a8 "
export CPPFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 -fpermissive "
export CXXFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 -frtti -fexceptions "
export CFLAGS=" ${ARCH_FLAGS} -D__ANDROID_API__=$PLATFORM_VERSION -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 "
export LDFLAGS=" ${ARCH_LINK} "
I create the toolchain (in case of arm) with this command:
/home/joel/Android/Sdk/ndk-bundle/build/tools/make-standalone-toolchain.sh --arch=arm --platform=android-15 --toolchain=arm-linux-androideabi-4.9 --install-dir=/media/joel/0298EBFB98EBEADD/Alexa/AVSD
Also for your CMake, you're not setting up the Android Toolchain correctly. It should look something like this:
cmake
-DANDROID_PLATFORM=android-15
-DANDROID_ABI=armeabi-v7a
-DANDROID_STL=c++_shared
-DCMAKE_INSTALL_PREFIX:PATH=/media/joel/0298EBFB98EBEADD/Alexa/AVSD/out/armv7
-DCMAKE_TOOLCHAIN_FILE=/home/joel/Android/Sdk/ndk-bundle/build/cmake/android.toolchain.cmake
-DCMAKE_BUILD_TYPE=Debug
-DGTEST_LIBRARY=/media/joel/0298EBFB98EBEADD/Alexa/AVSD/out/armv7/lib/libgtest.a
-DGTEST_MAIN_LIBRARY=/media/joel/0298EBFB98EBEADD/Alexa/AVSD/out/armv7/lib/libgtest_main.a
-DGTEST_INCLUDE_DIR=../ThirdParty/googletest-release-1.8.0/googletest/include
-DGSTREAMER_MEDIA_PLAYER=ON
-DAMAZON_KEY_WORD_DETECTOR=OFF
-DKITTAI_KEY_WORD_DETECTOR=OFF
-DSENSORY_KEY_WORD_DETECTOR=OFF
-DACSDK_EMIT_SENSITIVE_LOGS=OFF ../ThirdParty/avs-device-sdk
The path for CMAKE_INSTALL_PREFIX and PKG_CONFIG_PATH should be the same. You build/install your library dependencies, then detect them in CMake as you go via pkg-config.
You can use the standalone NDK or the Android Studio bundled NDK. They're the same thing, just stored in a different path.
I build the GStreamer Android Universal Package from source, installing it into CMAKE_INSTALL_PREFIX. Same with the PortAudio OpenSLES lib. This lib will allow recording of audio in the Android emulator, which is pretty cool.
https://github.com/Gundersanne/portaudio_opensles
The approach I used was to start small, exercise the test cases, then added more complex dependencies, until it finally all worked.
Joel

Hello. I've followed the the Amazon devs' guide on building the SDK for Android and I've built it successfully, so now I'm trying to get the Sample app running on Android. My main problem right now is getting CMake to find GStreamer. I've downloaded the Android Universal Package bins and have tried setting -DCMAKE_INSTALL_PREFIX:PATH=${INSTALL_TARGET}:/path/to/gst_armv7 and -DCMAKE_PREFIX_PATH:PATH=${INSTALL_TARGET}:/path/to/gst_armv7. How do I get CMake to find the gstreamer files? @INRIX-joel-winarske, you mentioned that you installed the GStreamer Android Universal Package from source, but I can't find the source files anywhere. Do you happen to know where they're available? Thanks. |

Hi @INRIX-joel-winarske @mradulan @jwinarske @jie714 @jwinarske NDK Version used:16b As joel mentioned above, I copied the libs,executable and cert files to test device(android emulator). I'm facing run time issues related to libc++_shared.so(this library is copied from the lib64 folder in my standalone toolchain ). Please suggest a solution. Below pasting my tombstone output. Build fingerprint: 'Android/sdk_gphone_x86_64/generic_x86_64:8.0.0/OSR1.180418.003/4741120:userdebug/dev-keys' backtrace: stack: Preth |
|
I am using the gstreamer 1.8.2 files available from https://gstreamer.freedesktop.org/data/pkg/android. unzip and copy all the libs and pkgconfig files to the folder where you installed other libraries(which is specified by CMAKE_INSTALL_PREFIX).If you have already installed dependencies there will be a pkgconfig folder in your CMAKE_INSTALL_PREFIX path. So while copying please merge the pkgconfig files from the gstreamer folder. That's what I did. |

@JLu76 could you please send me the dev guide on building the SDK for Android? |

Hi All, ARNING: linker: libcurl.so: unused DT entry: type 0x6fffffff arg 0x1 (SampleApp:19907): GStreamer-CRITICAL : gst_object_unref: assertion 'object != NULL' failed Thanks |

@rjajra To start you are not building curl correctly. I need to have HTTP2 support... |
|
@preth-2018 When you build GStreamer and AVS client, they both need to use the same NDK, as well as the same API setting. So that the libs are linking to the same libraries that are present on the target. If you don't do this you will have lots of strange problems. |
|
Take a look at the Alexa Auto SDK. They have a working sample there. It's far from commercial ready, but gets you up an running on Android... One key issue with this sample, is that your Android Studio NDK may be newer than that of the bitbake build system. So you may need to regress your Android Studio NDK to match. |

Thanks for replying Joel. I tried the Auto SDK Sample Application and its working. Regards, |

AlexaClientSdkInit:initializeFailed:reason=curlDoesNotSupportHTTP2 But still I was getting the below runtime issue eventhough all gstreamer plugins are cross compiled and installed. == (SampleApp:19907): GStreamer-CRITICAL : gst_object_unref: assertion 'object != NULL' failed Thanks |
|
I was also facing the same issue(arm-v7a) . You can refer this thread also .It might help. regards |

After setting GST_PLUGIN_PATH, I was getting "Bus Error" export GST_PLUGIN_PATH_1_0=/data/gstplugins/usr/lib/gstreamer-1.0 === any help on this error?. Thanks |

Hi, I am try for the same procedure to deploy AVS SDK on android Ore 8.1, running on resepaker. I followed this guide but I am not able to setup AVS SDK on android. https://github.com/alexa/avs-device-sdk/wiki/Android-Quick-Start-Guide. I have ubuntu and installed all the packages as per the procedure, I am not able to run shell and bash to install setup.sh config.txt and It says bash not found. I complied the code bash -x setup.sh config.txt after adb connected devices, script ran but it didnt install on the device but I got an error

I see the following error pattern in cases which are calling AddMember with type of std::chrono::duration_caststd::chrono::milliseconds. If you cast this type to (uint64_t) in all cases, it's happy. If there is a better solution on it's way - great, otherwise I can submit a PR.
