Failed to find 'ANDROID_HOME' environment variable

You may want to confirm that your development environment has been set correctly.

Quoting from spring.io:

Set up the Android development environment

Before you can build Android applications, you must install the Android SDK. Installing the Android SDK also installs the AVD Manager, a graphical user interface for creating and managing Android Virtual Devices (AVDs).

  1. From the Android web site, download the correct version of the Android SDK for your operating system.

  2. Unzip the archive to a location of your choosing. For example, on Linux or Mac, you can place it in the root of your user directory. See the Android Developers web site for additional installation details.

  3. Configure the ANDROID_HOME environment variable based on the location of the Android SDK. Additionally, consider adding ANDROID_HOME/tools, and ANDROID_HOME/platform-tools to your PATH.

Mac OS X

export ANDROID_HOME=/<installation location>/android-sdk-macosx
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

Linux

export ANDROID_HOME=/<installation location>/android-sdk-linux
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

Windows

set ANDROID_HOME=C:\<installation location>\android-sdk-windows
set PATH=%PATH%;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools

The Android SDK download does not include specific Android platforms. To run the code in this guide, you need to download and install the latest SDK platform. You do this by using the Android SDK and AVD Manager that you installed in the previous section.

  1. Open the Android SDK Manager window:

    android

    Note: If this command does not open the Android SDK Manager, then your path is not configured correctly.

  2. Select the Tools checkbox.

  3. Select the checkbox for the latest Android SDK.

  4. From the Extras folder, select the checkbox for the Android Support Library.

  5. Click the Install packages... button to complete the download and installation.

    Note: You may want to install all the available updates, but be aware it will take longer, as each API level is a large download.


These are the steps that you need to follow to successfully set up your Ionic Project to work with android emulator:

  1. Create an Ionic Project: ionic start appName tabs (for tab theme)
  2. cd appName
  3. ionic setup sass
  4. To start the app on web: ionic serve

To add android platform:

Priori Things

First you need to setup the environment variables. For this you need to consider 3 files:

1. ~/.profile (For setting up the variables every time terminal opens or computer boots up):

//Code that you need to append at the last

set PATH so it includes user's private bin directories
PATH="$HOME/bin:$HOME/.local/bin:$PATH"
export ANDROID_HOME='/home/<user_name>/Android/Sdk' <Path to android SDK>
export PATH=$PATH:$ANDROID_HOME/bin
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools

2. /etc/environment (to set the environment variables):

//All the content of the file

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
JAVA_HOME="/usr/lib/jvm/java-8-oracle"
ANDROID_HOME="/home/<user_name>/Android/Sdk" <Path to android SDK>

3. /etc/profile:

//Code that you need to add at the last

JAVA_HOME=/usr/lib/jvm/java-8-oracle <Path where Java is installed>
JRE_HOME=$JAVA_HOME/jre 
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME
export JRE_HOME
export PATH

For loading the above changes made to the file you need to run the following command:

source ~/.profile
source /etc/environment
source /etc/profile

Posteori Things

1. Add platform: ionic platform add android (Note that you need to run this command without sudo)

2. If you are still getting error in the above command then do the following: (here appName = helloWorld)

    cd ..
    sudo chmod -R 777 helloWorld
    cd helloWorld 
    ionic platform add android
    If you are still getting the error then remove ".cordova" folder from the home directory of your PC.

3. To run the app in your android emulator: ionic run android

Thanks!


In Linux

First of all set ANDROID_HOME in .bashrc file

Run command 

sudo gedit ~/.bashrc

set andoid sdk path where you have installed

export ANDROID_HOME=/opt/android-sdk-linux 
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

to reload file run command

source ~/.bashrc

Now check installed platform, run command

ionic platform

Output

Installed platforms:
  android 6.0.0
Available platforms: 
  amazon-fireos ~3.6.3 (deprecated)
  blackberry10 ~3.8.0
  browser ~4.1.0
  firefoxos ~3.6.3
  ubuntu ~4.3.4
  webos ~3.7.0

if android already installed then need to remove and install again 

ionic platform rm android
ionic platform add android

If not installed already please add android platform

ionic platform add android

Please make sure you have added android platform without sudo command

if you still getting error in adding android platfrom like following

Error: EACCES: permission denied, open '/home/ubuntu/.cordova/lib/npm_cache/cordova-android/6.0.0/package/package.json'

Please go to /home/ubuntu/ and remove .cordova folder from there

cd /home/ubuntu/
sudo rm -r .cordova

Now run following command again 

ionic platform add android

after adding platform successfully you will be able to build andoid in ionic.

Thanks
