[android] How do I set ANDROID_SDK_HOME environment variable?

I'm working with Eclipse on Windows 7, x64. I'm getting an error when running ADT bundle of android development:

Error: Error parsing the AVDs
Unable to get the Android SDK home directory.
Make sure the environment variable ANDROID_SDK_HOME is set up.

I know what the issue is. Is it because it is linked to a wrong directory C:users:????

How do I set this environment variable android_sdk_home to the proper directory?

Just set the path to the Android SDK directory

flutter config --android-sdk c:\android\sdk

Android SDK

Installing the Android SDK is also necessary. The Android SDK provides you the API libraries and developer tools necessary to build, test, and debug apps for Android.

Cordova requires the ANDROID_HOME environment variable to be set. This should point to the [ANDROID_SDK_DIR]\android-sdk directory (for example c:\android\android-sdk).

Next, update your PATH to include the tools/ and platform-tools/ folder in that folder. So, using ANDROID_HOME, you would add both %ANDROID_HOME%\tools and %ANDROID_HOME%\platform-tools.

If you face the same error, here are the step by step instructions:

1. Open control panel
2. Then go to System
3. Then go to Change Environment Variables of the User
4. Then click create a new environment variables
5. Create a new variable named ANDROID_SDK_HOME
6. Set its value to your Android directory, like C:/users/<username>/.android

Although the above answers mostly get them right, there is one slight issue with them all.. Follow these steps and you are good to go

1. Right click on This PC -> Properties
2. On the left pane select "Advanced System Settings"
3. On the new window select -> Advanced tab
4. Click on the "Environment Variables" button
5. On the first top section click on the "New" button

set variable name -> ANDROID_HOME

set variable value -> the custom location of the Android SDK

6. Now click on the newly created variable name and in the box below select "Path" and click on the Edit button
7. Now click on New and paste the location of the "platform-tools"
8. Again click on New and paste the location of the "tools" You can find the locations of the above platform-tools and tools - they are generally inside the Android SDK folder
9. MOST IMPORTANT OF ALL...

   save all those by clicking ok If you are using the terminal(cmd) close it and open it again

from command prompt:

set ANDROID_SDK_HOME=C:\[wherever your sdk folder is]

should do the trick.

Copy your SDK path and assign it to the environment variable ANDROID_SDK_ROOT

Refer pic below:

open your adt and open preferences, then modify directory with your sdk dir, it may help you follow the pic link indication

AVD cant find SDK root, possibly because they are in different directories.Set your environment variables as shown in the screenshot below:

This worked for me:

1. Open control panel
2. click System
3. Then go to Change Environment Variables
4. Then click create a new environment variables
5. Create a new variable named ANDROID_HOME path C:\Android\sdk

ANDROID_HOME

Deprecated (in Android Studio), use ANDROID_SDK_ROOT instead.

ANDROID_SDK_ROOT

Installation directory of Android SDK package.

Example: C:\AndroidSDK or /usr/local/android-sdk/

ANDROID_NDK_ROOT

Installation directory of Android NDK package. (WITHOUT ANY SPACE)

Example: C:\AndroidNDK or /usr/local/android-ndk/

ANDROID_SDK_HOME

Location of SDK related data/user files.

Example: C:\Users\<USERNAME>\.android\ or ~/.android/

ANDROID_EMULATOR_HOME

Location of emulator-specific data files.

Example: C:\Users\<USERNAME>\.android\ or ~/.android/

ANDROID_AVD_HOME

Location of AVD-specific data files.

Example: C:\Users\<USERNAME>\.android\avd\ or ~/.android/avd/

JDK_HOME and JAVA_HOME

Installation directory of JDK (aka Java SDK) package.

Note: This is used to run Android Studio(and other Java-based applications). Actually when you run Android Studio, it checks for JDK_HOME then JAVA_HOME environment variables to use.
