ndk-build and command not found using Eclipse mac

I am developing and android application in mac using Eclipse for android-ndk. I have already given NDK path in Eclipse. At the end when I am giving this command to build my application using android-ndk but getting the following errors:
command: ndk-build
ndk-build-bash: ndk-build: command not found

At the end i am getting ndk-build error.

Instead of ndk-build command, simply type ~/Desktop/AndroidNDK/android-ndk-r10d/ndk-build in your terminal.

I didn't give any explicit values for ANDROID_NDK_ROOT and ANDROID_SDK_ROOT, i just give the location of my NDK in my eclipse preferences. Can you please guide me in this thing
According to the Android folks on the Android NDK group (see Recommended NDK Directory?), uou should always provide values for ANDROID_NDK_ROOT, ANDROID_SDK_ROOT and ANDROID_SDK_HOME. Here is what they are used for:
ANDROID_NDK_ROOT → installation dirctory of NDK
ANDROID_SDK_ROOT → installation dirctory of SDK
ANDROID_SDK_HOME → location of SDK-related user files, defaults to ~/.android/ on Unix.
Put the tools on-path and export the env vars. Here's my .bash_profile for OS X.
$ cat ~/.bash_profile
export PS1="\h::\W$ "
# Android
export ANDROID_NDK_ROOT=/opt/android-ndk-r10d
export ANDROID_SDK_ROOT=/opt/android-sdk-macosx
export ANDROID_SDK_HOME=~/.android
export JAVA_HOME=`/usr/libexec/java_home`
export PATH="$ANDROID_SDK_ROOT/tools/":"$ANDROID_SDK_ROOT/platform-tools/":"$PATH"
Then, source your profile changes (or log-off and then log-in).

Jenkins - Warnings Plugin & IntelliJ IDEA Parser

I am having issues opening the files that contains IntelliJ IDEA Inspection warnings using Jenkins and Warnings Plugin.
The path to my files looks weird - file://$PROJECT_DIR$/app/src/main..../Foo.java in the .xml generated files by ./inspect.sh
When I click on the file I get the following error:
`java.io.IOException: Failed to copy file:/$PROJECT_DIR$/app/src/main/java`/
These are some screenshots of my files:
I am using the ./inspect.sh from Android Studio, not from actual IntelliJ. Could that be the problem?
Thanks in advance.

In the end I have added an extra build step where I clean the .xml files that are output by ./inspect.sh.
I have also added a line of code that removes all the inspects related to the build (generated) directory. Hope this helps anyone who was stuck with this issue.
Below you have the tweaked inspect.sh file and the two separate build steps:
inspect.sh
#!/bin/sh
#
# ------------------------------------------------------
# Android Studio offline inspection script.
# ------------------------------------------------------
#
export DEFAULT_PROJECT_PATH="$(pwd)"
cd ..
exec "MacOS/studio" inspect "$#"
Build Step 1
cd ${WORKSPACE}/inspectionsresults
rm *.xml
cd "${ANDROID_STUDIO_HOME_BIN}"
./inspect.sh ${WORKSPACE} ${WORKSPACE}/inspections_profile.xml ${WORKSPACE}/inspectionsresults -v2 -d ${WORKSPACE}/app
Build Step 2
cd ${WORKSPACE}/inspectionsresults
sed -i .bak "s,file://\\\$PROJECT_DIR\\\$,${WORKSPACE},g" *.xml
sed -i .bak "s,file:///,,g" *.xml
/usr/local/bin/xml ed -L -d "/problems/problem[contains(file,'generated')]" *.xml
rm *.bak
I have used xmlstarlet to remove the "generated" problems.
brew install xmlstarlet

Building webrtc library

I am trying to build webrtc android demo application. I was following README applied by the project. First thing was mentioned about gclient but when i tried to run it "no external or internal command". Then i got this link according to the this link i cloned the depot_tool repository but when at the step when i try to run gclient i got this
So after hours of trying i am not able to run it. if any one has experience with this WebRTC library please provide some help. Any guidance? Any Hlep will be appreciated

I heard few things were changed from svn to GIT. We tried building webRTC to windows7 using visual studio. See if you can use any parts on this.
Get depot_tools software and extract to a location (set this path in environment variable).
cd to depot_tools directory and hit 'gclient' (this should take sometime)
Install python 2.7 and put it path.
create a folder of your choice for webRTC and open command prompt there.
Now hit, gclient config http://webrtc.googlecode.com/svn/trunk
then, gclient sync.
Then set GYP_GENERATORS=msvs environment variable (use ninja if you want that).
Also set msvs_version=2012 (depending on your visual studio version)
now run, gclient runhooks --force
This should generate solutions files for your folder. fireup the libjingle/webrtc.sln files and start building it. I'm not sure if it builds as is. But we had hicupps with that.
See this link on WebRTC native development if you haven't already. From my personal experience building this tricky job initially.
Also note that links might be deprecated as they moved to git, don't know if they are still maintaining it.

i got this codes from a site. (http://www.apriorit.com/our-company/dev-blog/233-how-to-build-apk-file-from-command-line)
i downloaded the source code sample and opened the batch file in there but it didn't generate it's apk file. usually the apk file is located at its bin\ right? but when i opened the folder, the file is not in there. please help me how to use this one. i'd appreciate you help.

You’ll have to have Apache ant for this one:
ant debug
This will build and sign the necessary .apk files.
For more info, please see this: http://codeseekah.com/2012/02/09/command-line-android-development-basics/
EDIT:
ant is not a part of standard Android SDK setup. You'll have to install it.
Download the latest ant zip file from The Apache Ant Project.
Extract the zip file to a folder, say c:\ant\
Add c:\ant to your path environment variable
Once these are done, you'll be able to run ant from the command line

The apk by default is located under bin and this is correct, but when you distribute source code it's better to not add any apk because a "fresh" compiled apk is always a better solution.
if you have a file called build.xml in the root of your project just do
ant debug
otherwise you need to update your project with the minimum informations required for the building phase with
android update project -t android-10 -p .
in this case android-10 is a target for your apk/app/api and you can customize this option for your targeted device.
After this you get your build.xml and everything is in place for generating an apk.

ant debug install
is actually viable if you create project with (note that you should specify the virtual device with "adb -s" command while installing if you're running multiple devices)
android create project -n <project_name>
-t <target_version> -p <path> -k <package> -a <activity>
and use this command to run on the avd (if you've started one)
adb -e shell "am start -a android.intent.action.MAIN -n com.your.package/.YourActivity"
(change -e option to -d if you're running on devices)
reference
better use "AVD Manager.exe" to start a virtual device if you don't know those command or parameters, as there're quite a lot.

One of the best example I found on Internet for creating Android APK is https://geosoft.no/development/android.html.Also you can use assembleDebug command in root directory (make sure setting gradle as environment variable), if you are using Gradle.

android monkey runner scripts

i am tryig to execute a sample python program through monkey runner command prompt and it is throwing an error
Can't open specified script file
Usage: monkeyrunner [options] SCRIPT_FILE
-s MonkeyServer IP Address.
-p MonkeyServer TCP Port.
-v MonkeyServer Logging level (ALL, FINEST, FINER, FINE, CONFIG, INFO,
WARNING, SEVERE, OFF)
Exception in thread "main" java.lang.NullPointerException
so any one can guide me how to resolve this one

scriptfile should be a full path file name
try below
monkeyrunner c:\test_script\first.py

try using something like
...\tools>monkeyrunner -v ALL first.py
where first.py was my sample python script which I copied into tools folder of android SDK (the place where monkeyrunner.bat is located)

Under all unix/linux families OS the sha bang syntax can be used.
Edit the first line of your script with the results of the following command:
which monkeyrunner
for example, if monkeyrunner (usually provided with android sdk) has been installed under /usr/local/bin/sdk write:
#!/usr/local/bin/sdk/tools/monkeyrunner
or even use "env"
#!/usr/bin/env monkeyrunner
then set you script file as executable
chmod +x <script>
You can now launch your script from the shell.

It looks not make sense to switch working directory to Android SDK folder but just for obtain some relative references path for itself. It means you have to specify the full path for your script file and the PNG image files you want to save or compare to.
A better way is modify few lines in the "monkeyrunner.bat" under your SDK folder as below. This will use your current path as working directory, so, no necessary to use full path file name.
rem don't modify the caller's environment
setlocal
rem Set up prog to be the path of this script, including following symlinks,
rem and set up progdir to be the fully-qualified pathname of its directory.
set prog=%~f0
rem Change current directory and drive to where the script is, to avoid
rem issues with directories containing whitespaces.
rem cd /d %~dp0
rem Check we have a valid Java.exe in the path.
set java_exe=
call %~sdp0\lib\find_java.bat
if not defined java_exe goto :EOF
set jarfile=monkeyrunner.jar
set frameworkdir=
set libdir=
if exist %frameworkdir%%jarfile% goto JarFileOk
set frameworkdir=%~sdp0\lib\
if exist %frameworkdir%%jarfile% goto JarFileOk
set frameworkdir=%~sdp0\..\framework\
:JarFileOk
set jarpath=%frameworkdir%%jarfile%
if not defined ANDROID_SWT goto QueryArch
set swt_path=%ANDROID_SWT%
goto SwtDone
:QueryArch
for /f %%a in ('%java_exe% -jar %frameworkdir%archquery.jar') do set swt_path=%frameworkdir%%%a
:SwtDone
if exist %swt_path% goto SetPath
echo SWT folder '%swt_path%' does not exist.
echo Please set ANDROID_SWT to point to the folder containing swt.jar for your platform.
exit /B
:SetPath
call %java_exe% -Xmx512m -Djava.ext.dirs=%frameworkdir%;%swt_path% -Dcom.android.monkeyrunner.bindir=%frameworkdir%\..\..\platform-tools\ -jar %jarpath% %*

I met the same things as you did, I resolved by using "monkeyrunner" command under tools, and your script file should be a full path name. It looks like the directory “tools” is the main directory of MonnkeyRunner. I am depressed that I can't run my script files by pydev IDE directly.

monkeyrunner.bat cygpath -w $(pwd)/monkey.py
