How to add android ionic platform

I've been able to install ionic and create the necessary files for the app by "$ionic start myApp tabs" but when i tried to build the app "ionic platform add android"
i'm getting this error http://i.stack.imgur.com/P4HDQ.png
I've looked online for any solutions and found some with no luck

You will need to go to your environment variables and update the below to your path.
android-sdk\platform-tools
android-sdk\tools
apache-ant-1.9.4\bin
jdk1.8.0_31\bin
Depending on your OS, for windows 8 the quickest way to get to the window to edit your path is by clicking the windows key on your keyboard and searching environment variables. The first item in the list, "edit environment variables for your account" is correct. Make sure you add the full path of each of the above.
Your PATH variable should look something like this...
C:\Users[user]\AppData\Local\Android\android-sdk\platform-tools;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files\nodejs\;C:\Program Files (x86)\Git\cmd;C:\Program Files (x86)\Git\bin;C:\Users[user]\AppData\Local\Android\android-sdk\tools;C:\Users[user]\Documents\Development\sdks\apache-ant-1.9.4\bin;%JAVA_HOME%\bin;C:\Users[user]\AppData\Roaming\npm
Where I have %JAVA_HOME% I have simply named a new variable JAVA_HOME which has the following path...
C:\Program Files\Java\jdk1.8.0_31
I did this simply to make the string of text in PATH shorter. You can just replace, where I have %JAVA_HOME%, with C:\Program Files\Java\jdk1.8.0_31 or where ever your path to jdk1.8.0_31 .
Please make sure that you put in the correct path that is relevent to where you have each of these and don't copy what I have above as this will not work for you.

Gradle can't user JAVA_HOME while debugging from Android Studio

I'm trying to compile a project in android studio and it gives the
Could not execute build using Gradle distribution 'http://services.gradle.org/distributions/gradle-1.6-bin.zip'.
I've already red that to gather more information i should use:
gradlew compileDebug --stacktrace
from the main folder, but when i do that i get that error:
JAVA_HOME is set toan invalid directory: C:\Program Files (x86)\Java\Jre7\bin\java.exe;
Please note that i tried to use a 64 bit version of the jre too in the JAVA_HOME path.
Anyone can give me some help ?
Thanks in advance

Change the value of environment variable JAVA_HOME to C:\Program Files (x86)\Java\Jre7\ instead of C:\Program Files (x86)\Java\Jre7\bin\java.exe
JAVA_HOME should be always pointing to the parent directory of JDK or JRE installation inside of which, we find the bin directory containing the java, javac, etc. binaries

I might be reading too much into the error message, but shouldn't JAVA_HOME look more like C:\views\p4\library\bea-jrockit\1.6.0_29\windows-x86_64\dist?
Notice that it points to a folder called 'dist' instead of to the java.exe itself. To help you figure out the folder, 'dist' has inside of it 'bin'. So maybe try something more like C:\Program Files (x86)\Java\Jre7\?

New android SDK 17 issue in my app?

Today i was update my android sdk to new android adk-17 .
i am facing some problems in this, that is unable to show AddMob in my app, if i remove addmob in the code able to run the app without any errors otherwise not. what is the solution for this, is this bug in new sdk.
this is the Logcat information
Caused by: java.lang.ClassNotFoundException: com.google.ads.AdView in loader
dalvik.system.PathClassLoader[/data/app/com.veritra.iflipout-1.apk]

Maybe the ADK update has messed-up with your project's build-path.
Try removing the admob JAR and add it again to your libs folder, add it to your Build Path and do a Clean Project.
Anyway it's hard to help you without more details on the error you encounter.
EDIT following poster's comment about not having a libs folder:
You should try this:
Remove all references to the AdMob JAR in your project -> your code should not build without error anymore
Create à libs folder at the root of your project
Copy the AdMob JAR into the libs folder
Make sure this AdMob JAR is in your Build Path (this will allow your code to build wihtout error)
(If still not running OK) Right click your project > Android Tools > Fix Project Properties

The 'problem' here is that the SDK is a lot more strict about the libraries. If you do not check the library as 'exported' in eclipse, it is not added to your APK, leading to this nasty class not found exception. You should mark your libraries as exported.
Project Properties | Java Build Path | Order and Export

when I updated my SDK it was total mess. Well, the only I had to change was the PATH in Environment Variables.
http://developer.android.com/sdk/installing.html :
Adding both tools/ and platform-tools/ to your PATH lets you run command line tools without needing to supply the full path to the tool directories. Depending on your operating system, you can include these directories in your PATH in the following way:
On Windows, right-click on My Computer, and select Properties. Under the Advanced tab, hit the Environment Variables button, and in the dialog that comes up, double-click on Path (under System Variables). Add the full path to the tools/ and platform-tools/ directories to the path.
On Linux, edit your ~/.bash_profile or ~/.bashrc file. Look for a line that sets the PATH environment variable and add the full path to the tools/ and platform-tools/ directories to it. If you don't see a line setting the path, you can add one:
export PATH=${PATH}:/tools:/platform-tools
On a Mac OS X, look in your home directory for .bash_profile and proceed as for Linux. You can create the .bash_profile if you don't already have one.

Set classPath for java

I am trying to run the draw9patch.bat from my cmd but it throws the following error.
WARNING: Java not found in your path.
Checking if it's installed in C:\Program Files\Java instead (64-bit).
Checking if it's installed in C:\Program Files\Java instead.
ERROR: No suitable Java found. In order to properly use the Android Developer
Tools, you need a suitable version of Java JDK installed on your system.
We recommend that you install the JDK version of JavaSE, available here:
http://www.oracle.com/technetwork/java/javase/downloads
You can find the complete Android SDK requirements here:
http://developer.android.com/sdk/requirements.html
I have java installed and have also tried changing the classpath from environment variables in the control panel.However it does not seem to solve the problem.What am i doing wrong.

For that you need to set the 'path' environment variable.
Something like this:
path=%path%;c:\program files\java\jdk 1.6\bin
or
the path where you have installed the java.

You may need the swing-worker-1.1.jar, place this in Android-sdk/tools/lib directory.

For people who are looking for solution for Windows 7 (maybe for xp too) and that last answers wasn't the right solution.
If you have problem with running this file, this problem will happens in almost all .bat files in android-sdks/tools files.
Here is what to do and all that batch files will work okay.
I assume that you have downloaded proper JDK so..
Go to folder android-sdks\tools\lib and edit file find_java.bat
Delete all text stored inside and insert into something like that:
set java_exe="C:\Program Files\Java\jre7\bin\java.exe"
if not defined java_exe goto :CheckFailed
:SearchJavaW
set javaw_exe="C:\Program Files\Java\jre7\bin\javaw.exe"
if not exist %javaw_exe% set javaw_exe=%java_exe%
goto :EOF
Please be carefull and put correct path to jre what you have! Here is an example for jre7!

How to set GNUMAKE variable for ndk-build to work

I am trying to make ndk-build to work within Cygwin on windows. As per the NDK documentation (specifically INSTALL.htm), "The NDK requires GNU Make 3.81 or later being available on your development."
I have Gnu Make installed on my computer.
So far, so good.
Within Cygwin bash, I cd over to the android NDK root directory. Now when I type in the following command (without parameters right now, just to see if the command works):
$./ndk-build
ERROR: Cannot find 'make' program. Please install Cygwin make package or define the GNUMAKE variable to point to it.
So I try to set the GNUMAKE variable, but no luck:
$export GNUMAKE='/cygdrive/c\Program Files\GnuWin32\bin'
ERROR: Your GNUMAKE variable is defined to an invalid name: /cygdrive/c\Program Files\GnuWin32\bin
Please fix it to point to a valid make executable (e.g. usr/bin/make)
I even tried setting it to usr/bin/make as it suggests, but same invalid name error.
Anyone, knows how to resolve this?
I'm using Windows 7, NDK r5, Cygwin 1.7.1

I had an issue with GNUMake when putting the ndk in a folder with a space in it (I originally put it in the program files directory). I moved everything to C:/android/android-ndk and C:/android/android-sdk and updated my path settings to include these directories.

Its not problem with the make but installing cygwin
in ndk-demo script the make path is found using which command mostly which command
installation is missing in cygwin.
Solution:
Relaunch your cygwin installation select utils (install )
Checking:
$ which make
should give you the make command path on cygwin prompt.

Vasu

This is a generic error. It means there was a problem somehow with the make command, but the error message itself is hidden. To help diagnose the problem, open your ndk_build script in the ndk directory, and change these lines:
ABS_GNUMAKE=`which $GNUMAKE 2> /dev/null`
...
GNUMAKE=`which make 2> /dev/null`
to these:
ABS_GNUMAKE=`which $GNUMAKE`
...
GNUMAKE=`which make`
And then you will get a more detailed error message. Note that it might not even be a problem with the 'make' command, it might be a problem with the 'which' command. Make sure you have cygwin installed.

delete Environmental variable GNUMAKE
close the cygwin terminal
open again cygwin terminal... go the path where u want to build.. and now build it...
I am sure hopefully you will build successfully..as i do..

The answer with moving NDK to a directory without spaces is definitely right. After that you will probably able to run ndk-build from the Cygwin shell.
However running ndk-build from Windows commmand line (like "bash ndk-build") will probably cause the same queer error with "incorrect GNU make".
It is reproducible with NDK 6b as well.
And I hope it is fixed in the newest version of NDK...

ERROR: Cannot find 'make' program. Please install Cygwin make package
or define the GNUMAKE variable to point to it.
While trying to install Cygwin i missed out to install MAKE PACKAGE
Just need to search make in the Search box and it will shows the Branches that includes devel branch and from devel branch i selected make package.
That's all issue fixed.

i worked hard on error in gygwin terminal "gnumake variable is define to invalid name" and after that i get to the point that we simply remove this error by deleting the GNUMAKE path in environment variable both in system and user variable if u created it hope its helps....
mycomputer > system properties > advanced system setting > environment variable

The problem here is the name of the GNUMAKE variable.The name given was
/cygdrive/c\Program Files\GnuWin32\bin change it into /cygdrive/c/Program Files/GnuWin32/bin/make
only use forword Slash .Sometime the space in the folder structure does not taken
Happy coding.
