Android Home应该是SDK的根文件夹。

  export ANDROID_HOME =$ HOME / android-sdk-linux
 pre> 

  EDIT ：打开终端并键入这些命令。 （是，在ternimal，不在bashrc文件中）
  export ANDROID_HOME =〜/ android-sdk-macosx 
 PATH = $ PATH：$ ANDROID_HOME / tools 
 PATH = $ PATH：$ ANDROID_HOME / platform-tools 
 
然后在同一个终端只需键入 android 。如果配置，您将能够使用从此终端的构建命令。 （这是一个临时解决方案）
 
I am trying to build android for ionic in linux but its showing me an error like this 
     [Error: Failed to find 'ANDROID_HOME' environment variable. 
      Try setting setting it manually.
      Failed to find 'android' command in your 'PATH'. 
      Try update your 'PATH' to include path to valid SDK directory.]
      ERROR building one of the platforms: Error: /home/kumar/myapp/platforms/android/cordova/build: Command failed with exit code 2

at Process.ChildProcess._handle.onexit (child_process.js:810:5)
and i've added this in my bashrc file 
export ANT_HOME="/usr/bin/ant"
export PATH="$PATH:$ANT_HOME/bin"
export HOME="/home/kumar"
export ANDROID_HOME="$HOME/android-sdk-linux/tools"
export ANDROID_PLATFORM_TOOLS="$HOME/android-sdk-linux/platform-tools"
export PATH="$ANDROID_HOME:$ANDROID_PLATFORM_TOOLS:$PATH"
I'm thinking i've given the path but i dont know why its showing me this error .. Please help....
Android Home should be the root folder of SDK. 
export ANDROID_HOME="$HOME/android-sdk-linux"
EDIT:  Open terminal and type these commands. (yes, on a ternimal , not in bashrc file)
export ANDROID_HOME=~/android-sdk-macosx
PATH=$PATH:$ANDROID_HOME/tools
PATH=$PATH:$ANDROID_HOME/platform-tools    
and then in the same terminal just type android. If configured you would be able to use build commands from this terminal. (it's a temporary solution)
