I have gone through this NDK example link.And i did all.But ndk-build not working(command not found).I tried ./ndk-build also but no success.I set the path variable too.I am using Ubuntu OS.Any help.Ndk path in bash.bashrc file is like this:
export NDK_HOME=/home/android/android-ndk-r8e-linux-x86/android-ndk-r8e/
The big problem is i am doing cd to this folder in command prompt and doing ndk-build and it's not working.The file inside this filder is ndk-build.cmd
If you want to run ndk-build this way, you need the path of the executable file to be in the PATH env variable. Otherwise you have to specify the entire path to ndk-build. For instace /home/username/ndkpath/ndk-build
Seems that you have get wrong the path, instead use
export NDK_HOME=/home/android/android-ndk-r8e-linux-x86/

How to solve artoolkit nftBook issues in android studio
When I run the command ndk-build in android studio terminal for nft book it shows the error like:
clang++.exe: error: linker command failed with exit code 1 (use -v to
see invocation) make: *** [obj/local/armeabi/libnftBookNative.so]
Error 1
How can I solve this?
You should not run it in the android studio terminal but in the Git-Bash.
Read the documentation more closely :).
You look like you are working from Windows so you need to use Git-Bash for compilation.
See: http://artoolkit.org/community/forums/viewtopic.php?f=26&t=17092
===========
EDIT:
Make sure you have these environment variables set:
- Set ANDROID_HOME to indicate the path to root folder of the downloaded Android SDK.
Set ANDROID_NDK_ROOT to indicate the path to root folder (most likely, “ndk-bundle”) of the downloaded NDK. The ANDROID_HOME environment variable can be used to help define NDK.
ANDROID_NDK_ROOT=$ANDROID_HOME/ndk-bundle
Set NDK to the same path as ANDROID_NDK_ROOT. NDK=$ANDROID_NDK_ROOT
Set PATH to include a path to the ndk-build[.cmd] script file, that is, the path to the root folder of the NDK. The NDK environment variable can be used to help define the added path.
Now start gitBash and navigate to your ARToolKit5_ROOT directory.
cd android
./build.sh
if successful
./build_native_examples.sh
I'm facing the problem, that i cannot set the ANDROID_HOME path variable.
I added the following lines to my bashrc file:
# Android Path
export ANDROID_HOME=~/android-sdk/Sdk/tools
But when i try to access android via the terminal i get this error:
android: command not found
How can i solve this problem?
You need to add the variable in your PATH as well. The aim is for your PATH variable to contain the complete folder path, in which the file 'android' is present.
export ANDROID_HOME=~/android-sdk/Sdk/tools
export PATH=$ANDROID_HOME:$PATH
Don't forget to source your bashrc after adding these lines
source ~/.bashrc
Again, the file 'android' should be present in the tools folder.
Follow the following steps:
1)Open the bashrc file from command line
nano ~/.bashrc
2) Add following lines at the top.
export PATH=${PATH}:~/android-sdk-linux/tools
export PATH=${PATH}:~/android-sdk-linux/platform-tools
3)Now, quit terminal and re-launch, and try typing:
adb -h
android -h
If both commands are giving you output, it means everything works fine.
I have obstacle when run sudo ionc build android.
Error log terminal:
Set enviroment varibale in .profile:
Please give me solutions. How to setting PATH that true.
The system is not able to find the environment variable ANDROID_HOME in your .bashrc file. To resolve this error, you need to add the following to line to your ~/.bashrc file:
export ANDROID_HOME="<path/to/your/sdk/without/quotes>"
For me, I added the following
export ANDROID_HOME="/Users/chi6rag/Library/Android/sdk"
And ran source ~/.bashrc so that the configuration is loaded.
I use android studio with ndk and opencv. By default ndk-build command builds files under src/main/libs folder . I want to change it to src/main/jniLibs.
Add the option NDK_LIBS_OUT=<library output path> for ndk-build.
I wanna use tesseract library with my application so i need to implement ndk.i download it add its path to my bash_profile.
export ANDROID_ADB=/Users/gokhanaliccii/Library/Android/sdk/platform-tools
export ANDROID_NDK=/android_ndk/android-ndk-r10d
export PATH=$PATH:$ANDROID_ADB:$ANDROID_NDK
My problem is appeared when i run -javah command at studio terminal. My command is
javah -d jni -classpath /Users/gokhanaliccii/Library/Android/sdk/platforms/android-19/android.jar:/Users/gokhanaliccii/Documents/gokhan_private/android_ocr/NDK_TEST/app/build/intermediates/classes/debug gokhanaliccii.kou.ndk_test.MainActivity
after i got this error i tried to add support libraries
I tried to solved it but i coulndt find solution i'm really exhausted i hope someone know how to solve it
My project is at /Users/gokhanaliccii/Documents/gokhan_private/android_ocr/NDK_TEST
Dont need cp for javah
Run javac on source that includes file with native headers.
Cd to path that is parent of the root of where the ".class" files are.
On cli or in terminal run the javah ( no cp needed )
If stuvk do the ndk samples and it will make sense . They walk u thru javah sample
After lot of researches and training i solved my problem.
javah -classpath /Users/gokhanaliccii/Library/Android/sdk/platforms/android-19/android.jar:/Users/gokhanaliccii/Library/Android/sdk/extras/android/support/v7/appcompat/libs/android-support-v4.jar:/Users/gokhanaliccii/Library/Android/sdk/extras/android/support/v7/appcompat/libs/android-support-v7-appcompat.jar:../../build/intermediates/classes/debug -d jni gokhanaliccii.kou.ndk_test.MainActivit
My result command is above.I tried it at android studio,classes files are at build/intermediadtes/classes/debug if you want try it at eclipse it is under bin folder.
