I set the android_sdk_home variable so that my application could find .android when trying to run. Now I get an error stating that "android_sdk_root is undefined". I am running win 7 with a new installation of Android Studio, inside parallels on a macbook pro.
Thank you for your response. I checked the location and it is identified as the same location as the ANDROID_SDK_HOME environment path. It still says root is undefined. I created an ANDROID_SDK_ROOT enviroment path to the same location and it is still undefined.

You need to make a system env variable with the name: ANDROID_SDK_ROOT and it's value should be C:\Users\your_user_name\AppData\Sdk\tools\bin worked for me
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.
ANDROID_HOME, which also points to the SDK installation directory, is deprecated. If you continue to use it, the following rules apply: If ANDROID_HOME is defined and contains a valid SDK installation, its value is used instead of the value in ANDROID_SDK_ROOT. If ANDROID_HOME is not defined, the value in ANDROID_SDK_ROOT is used. If ANDROID_HOME is defined but does not exist or does not contain a valid SDK installation, the value in ANDROID_SDK_ROOT is used instead.
MAC - one liner
echo "export ANDROID_HOME=~/Library/Android/sdk \
export ANDROID_SDK_ROOT=~/Library/Android/sdk \
export ANDROID_AVD_HOME=~/.android/avd" \
>> ~/.bash_profile && source ~/.bash_profile
android_sdk_root is a system variable which points to root folder of android sdk tools. You probably get the error because the variable is not set. To set it in Android Studio go to:
If you have installed android SDK please refer to this answer to find the path to it: https://stackoverflow.com/a/15702396/3625900
Open the terminal and run the command: nano $HOME/.bashrc aggregate the follow line:
export ANDROID_HOME=$HOME/Android/Sdk
export ANDROID_SDK_ROOT=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools
Ctrl+o save and ctrl+x close.
And run the command:
source $HOME/.bashrc
echo $ANDROID_SDK_ROOT
This is how to change it :
Step 1 :
Open a Terminal / CMD As Administrator (Right-click on cmd and click "Run as Administrator")
Step 2:
type in " set ANDROID_SDK_ROOT=E:\Android\sdk\ " (type it without the quotes and replace "E:\Android\sdk" with your actual sdk file path location - Mine was : C:\Users\YOUR_ACCOUNT\AppData\Local\Android\Sdk
step 3:
Press "Enter" and i noticed nothing happened
Step 4:
Build your app again and it should reflect your file path. For me it doisplayed as :
Preparing Firebase on Android Checking Java JDK and Android SDK versions ANDROID_SDK_ROOT=C:\Users\Kurt\AppData\Local\Android\Sdk (recommended setting) ANDROID_HOME=C:\Users\Kurt\AppData\Local\Android\Sdk (DEPRECATED) Subproject Path: CordovaLib Subproject Path: app
I got that info from this site :
https://developer.android.com/studio/command-line/variables#android_sdk_root
Check it out for more information Have Fun!!
in mac os you can try brew install gradle
on Mac edit .bash_profile use code or vim
code ~/.bash_profile
export ANDROID_SDK_ROOT=~/Library/Android/sdk
export ANDROID_HOME=~/Library/Android/sdk
In Android Studio 3.2.1 I got this error because I installed a new API(28) level emulator without installing that API SDK components. After I installed SDK platform and SDK platform tools for the API level 28 and updated Android Emulator the emulator started running.
Hope it may help someone.
I followed this tutorial to set up my android environment variables I was on mac and I had all the required environmental variable setup and working already. but i was still getting this error that requires environment ANDROID_SDK_ROOT.
I already had an android SDK exported environment variable.
So, what I simply did is adding ANDROID_HOME to the path with the following commands:
export PATH=$PATH:$ANDROID_HOME
and it worked for me on macOS
This is how I did it on macOS:
vim ~/.bash_profile # macOS 10.14 Mojave and older
vim ~/.zshrc # macOS 10.15 Catalina and newer (using zsh by default)
And added the following environment variables:
export ANDROID_HOME=/Users/{{your user}}/Library/Android/sdk
export ANDROID_SDK_ROOT=/Users/{{your user}}/Library/Android/sdk
export ANDROID_AVD_HOME=/Users/{{your user}}/.android/avd
Android path might be different, if so change it accordingly. At last, to refresh the terminal to apply changes:
source ~/.bash_profile # macOS 10.14 Mojave and older
source ~/.zshrc # macOS 10.15 Catalina and newer (using zsh by default)
I received the same error after installing android studio and trying to run hello world. I think you need to use the SDK Manager inside Android Studio to install some things first.
Open up Android Studio, and click on the SDK Manager in the toolbar.
Now install the SDK tools you need.
For each Android release you are targeting, hit the appropriate Android X.X folder and select (at a minimum):
The SDK Manager will run (this can take a while) and download and install the various SDKs.
Inside Android Studio, File->Project Structure will show you where your Android sdks are installed. As you can see mine is c:\users\Joe\AppData\Local\Android\sdk1.
If I navigate to C:\Users\Joe\AppData\Local\Android\sdk1\sources you can see the various Android SDKs installed there...
For macOS with zshrc:
ANDROID_HOME is depreciated, use ANDROID_SDK_ROOT instead
/Users/<USER>/Library/Android/sdk
echo 'export ANDROID_SDK_ROOT=/Users/<USER>/Library/Android/sdk' >> ~/.zshenv
source ~/.zshrc
echo $ANDROID_SDK_ROOT
env
You can apply this process to every environment variable beeing installed on your macOS system. It took me a while to comprehend it for myself
