ics-openvpn : how to compile on windows machine

I get the latest source code on here :ics-openvpn and I want to compile it under windows environment. As in README.txt said :
Do cd main;./misc/build-native.(sh|bat) in the root directory of the
project. After that build the project using "gradle build" (Or use
Android Studio). The project is converted to gradle and building with
Eclipse is no longer supported.
But the content of file build-native.bat is:
#echo on
echo Currently broken, feel free to fix and send me a patch, see .sh file
exit 1
call ndk-build APP_API=all -j 8
cd libs
mkdir ..\assets
mkdir ..\build\
for /D %%f in (*) do (
copy %%f\minivpn ..\assets\minivpn.%%f
del %%f\libcrypto.so
del %%f\libssl.so
mkdir ..\build\native-libs\%%f\
copy %%f\*.so ..\build\native-libs\%%f\
)
cd ..
it means that author notices that this bat file contains error, that cannot be build by this. I try to remove first three lines and run again, i meet these errors:
main//jni/Android.mk:11: lzo/Android.mk: no such file or directory
main/jni/android.mk : 12: snappy/Android.mk : no such file or
directory ...
so, my question is : can we build this library on windows (because author has notified that this build file is error), and if can, how ?
Thanks :)

It is just like the text says. It is broken because I don't develop on Windows. You can look at the build-native.sh fix the paths etc for Windows. The build problems are nothing difficult but someone has to take the 10 minutes and fix it.

I got all sorts of errors using Cygwin to build this.
You may have more luck using an actual Linux box or something like VirtualBox with an Ubuntu image.
This worked for me. You will need the Linux NDK (installation instructions here) and you'll need to install make with sudo apt-get install make.
Then run cd main;./misc/build-native.sh from the project root.

How to build a JAR file using ant for uiautomator test project

I have been trying to get my head around using uiautomator and I understand creating the test cases. I tried the first two steps of building the JAR according the the Android developer guide for UI Testing (http://developer.android.com/tools/testing/testing_ui.html) and that worked fine, but I am unsure on how to follow the next steps and building the JAR file with ant. Please can anyone help me with this issue.
Here are the steps that I have done so far:
<android-sdk>/tools/android create uitest-project -n <name> -t 1 -p <path>
set ANDROID_HOME=<path_to_your_sdk>
This is the step that I am stuck on:
ant build
The error I get when I use the command prompt is:
'ant' is not recognized as an internal or external command, operable program or batch file.

In the terminal run
which ant
It seems you do not have ant installed. If no location like /usr/bin/ant shows up after you run the command above, use this to install it:
sudo apt-get install ant
Try again after. It should work.

If you're using ADT, I recommend downloading Apache ant and placing it within the sdk/tools/ant folder. Then change your PATH variable to direct to the ant bin folder.

you have this error because you wrote "ant build" from incorrect path.
I did (this command generate build.xml, local.properties, project.properties files):
<android-sdk>/tools/android create uitest-project -n <name> -t 1 -p <path>
I changed in build.xml first line like:
<project name="name" default="build">
after that I run ant from eclipse. Build was success.

Have you installed ant? If not then do it from this site: http://ant.apache.org/manual/install.html
If yes then follow these steps:
Navigate to your project directory and means (go to bin of your project)
Using command window execute the function: ant build
Ensure that your default JAVA_HOME points to JDK installation, not the JRE, and check if your compiler is in the PATH. Try to type “javac” in the command prompt. If javac is not found, then you should put your bin directory in the PATH.
For example, in Windows:
SET PATH=c:/jdk1.5.0_07/bin;%PATH%

If you have ADT with Eclipse then you can find ant in the plugins directory of Eclipse.

jenkins android can't find sdkmanager.jar

I'm running Jenkins on Mac OS. I have an ant build file that tries to execute <exec executable="android"> in one of the targets. I have the correct path as I've included android sdk tools and platform-tools folders to it, but I am still getting the following error.
android can't find sdkmanager.jar
If I move described jar from lib folder to tools folder I'm getting some other similar error related to another jar, so it seems it just can't get this jar from lib folder. Please help.

I solved my problem. I had correct path and sdk installation directory. Problem was that my Jenkins was running under another user and couldn't locate directory with android lib because they where denied for it. So problem was in sdk folder permissions.
I've just ran chmod -R 0755 mySdkDirLocation from console under bash and became the happiest developer on earth for the moment:)

After I ran chmod -R 0755 mySdkDirLocation. The error "android can't find sdkmanager.jar" went away. But when I ran android update sdk -u, I cannot install archives. So I ran chmod 777 mySdkDirLocation. Then the downloading worked.

NDK - Error trying to generate a build.xml file for Hello-jni

I just installed Android NDK, r5b, and while trying to follow the steps from Exploring the hello-jni Sample, on the command line I receive the error:
MacBook-2:~ mvermant$ cd ndk/samples/hello-jni
MacBook-2:hello-jni mvermant$ android update project -p . -s
-bash: android: command not found
I'm using Eclipse Helios release 2 with Android SDK r10 and ADT 10.0.0 on MAC 10.6.6. I have also checked to have GNU Make 3.81, and installed GNU Awk(though I am not sure it's in the right place).
I've searched a lot, and seems there might be a class path missing somewhere, but I can't figure out where exactly and what to do to fix it.

You should make sure the tools directory of your android-sdk is on your (shell) path.
Something like:
export PATH="/path/to/sdk/tools:$PATH"
before you execute your command.
In general you will also need two other directories to be on your path:
/path/to/sdk/platform-tools - for adb and other android sdk tools
/path/to/ndk - for ndk-build and ndk-gdb, which are ndk tools
You can also do some setup so that you don't have to run these commands every time you open Terminal.

android eclipse plugin can't find valid paths

I just installed the latest galileo eclipse release. I added the
latest adt plugin and configured it to use my android sdk (r4).
Unfortunately, the eclipse plugin is wiggin out. for some reason, it
can't find(execute?) the android tools. I get this error on the
eclipse project:
Error executing aapt. Please check aapt is present at
~/android-sdk-linux_86/platforms/android-1.6/tools/aapt
but here is the output of ls:
ls -al ~/android-sdk-linux_86/platforms/android-1.6/tools/aapt
-rwxrwxrwx 1 solid solid 3416259 2009-12-18 21:02 /home/solid/android-sdk-linux_86/platforms/android-1.6/tools/aapt
When I try running the program directly, I see the following:
~/android-sdk-linux_86/platforms/android-1.6/tools/aapt
bash: /home/solid/android-sdk-linux_86/platforms/android-1.6/tools/aapt: No such file or directory
I just unzipped the sdk and installed the platforms and ls'd it so I know it is there.
I have tried recreating the project from the command line (which
works) but when I import it into eclipse I get the same error.
BTW this is linux amd 64

Something is very wrong here. These two lines contradict themselves:
$ ls -al ~/android-sdk-linux_86/platforms/android-1.6/tools/aapt
-rwxrwxrwx 1 solid solid 3416259 2009-12-18 21:02 /home/solid/android-sdk-linux_86/platforms/android-1.6/tools/aapt
$ ~/android-sdk-linux_86/platforms/android-1.6/tools/aapt
bash: /home/solid/android-sdk-linux_86/platforms/android-1.6/tools/aapt: No such file or directory
The file just can't exist one instant, then cease to exist in the next.
I don't think this is caused by running on amd64, since I'd suspect that would give you a different, more descriptive error. That being said, make sure you have the ia32-libs installed:
# Assuming you're on Ubuntu
$ apt-get install ia32-libs
My only advice would be to try completely deleting your SDK installation and re-installing it from scratch.
